During the coldest night recorded, 14 January 1982, the temperature fell to −20.8 °C (−5.4 °F) at Birmingham Airport, but just −14.3 °C (6.3 °F) at Edgbaston, near the city centre. Birmingham is a snowy city relative to other large UK conurbations, due to its inland location and comparatively high elevation. Between 1961 and 1990 Birmingham Airport averaged 13.0 days of snow lying annually, compared to 5.33 at London Heathrow . Snow showers often pass through

#17328519400561644-506: A constantly diversifying range of products, in a highly entrepreneurial economy of small, often self-owned workshops. This led to exceptional levels of inventiveness: between 1760 and 1850 – the core years of the Industrial Revolution – Birmingham residents registered over three times as many patents as those of any other British town or city. The demand for capital to feed rapid economic expansion also saw Birmingham grow into
1781-627: A danger to health. Particulate toxicity has been found to vary by region and source contribution which affects the particles chemical composition. The chemical composition of the aerosol directly affects how it interacts with solar radiation. The chemical constituents within the aerosol change the overall refractive index . The refractive index will determine how much light is scattered and absorbed. The composition of particulate matter that generally causes visual effects, haze , consists of sulfur dioxide, nitrogen oxides, carbon monoxide, mineral dust, and organic matter. The particles are hygroscopic due to

Well-designed cyclonic separators can be very efficient in removing even fine particulates, and may be operated continuously without requiring frequent shutdowns for maintenance. Fabric filters or baghouses are the most commonly employed in general industry. They work by forcing dust-laden air through a bag-shaped fabric filter leaving
2055-456: A further postponement of the scheme during the pandemic, Birmingham City Council leader Ian Ward refused, noting: "The government has made it crystal clear it will not tolerate any further delay". When the plan was put forward again, businesses still recovering from lockdowns expressed concern about its potential economic impact. According to a report in The Guardian , shortly before the scheme

A study published in 2013 however, states that "the best estimate for the industrial-era (1750 to 2005) direct radiative forcing of atmospheric black carbon is +0.71 W/m with 90% uncertainty bounds of (+0.08, +1.27) W/m " with "total direct forcing by all-black carbon sources, without subtracting
2329-576: A haven for Nonconformists from the 1660s. By 1700 Birmingham's population had increased fifteen-fold and the town was the fifth-largest in England and Wales. The 18th century saw this tradition of free-thinking and collaboration blossom into the cultural phenomenon now known as the Midlands Enlightenment . The town developed into a notable centre of literary , musical , artistic and theatrical activity; and its leading citizens – particularly
2466-562: A high sulfur content, primarily coal and certain less-refined fuels, like aviation and bunker fuel , had dominated. By 1990, global human-caused emissions of sulfur into the atmosphere became "at least as large" as all natural emissions of sulfur-containing compounds combined , and were at least 10 times more numerous than the natural aerosols in the most polluted regions of Europe and North America, where they accounted for 25% or more of all air pollution. This led to acid rain , and also contributed to heart and lung conditions and even
2603-612: A major financial centre with extensive international connections. Lloyds Bank was founded in the town in 1765, and Ketley's Building Society , the world's first building society , in 1775. By 1800 the West Midlands had more banking offices per head than any other region in Britain, including London. Innovation in 18th-century Birmingham often took the form of incremental series of small-scale improvements to existing products or processes, but also included major developments that lay at

#17328519400563014-426: A net negative radiative forcing. The magnitude of the resultant radiative forcing due to the direct effect of an aerosol is dependent on the albedo of the underlying surface, as this affects the net amount of radiation absorbed or scattered to space. For example, if a highly scattering aerosol is above a surface of low albedo it has a greater radiative forcing than if it was above a surface of high albedo. The converse
3151-408: A particle. The SSA tends to unity if scattering dominates, with relatively little absorption, and decreases as absorption increases, becoming zero for infinite absorption. For example, the sea-salt aerosol has an SSA of 1, as a sea-salt particle only scatters, whereas soot has an SSA of 0.23, showing that it is a major atmospheric aerosol absorber. The Indirect aerosol effect consists of any change to

More recently, a destructive T6/F3 tornado occurred in July 2005 in the south of the city, damaging homes and businesses in the area. The tornado took an almost parallel path to that of
3562-738: A regional scale. The failure of the Indian monsoon has been linked to the suppression of evaporation of water from the Indian Ocean due to the semi-direct effect of anthropogenic aerosol. Recent studies of the Sahel drought and major increases since 1967 in rainfall in Australia over the Northern Territory , Kimberley , Pilbara and around the Nullarbor Plain have led some scientists to conclude that

The city was extensively redeveloped during the 1950s and 1960s. This included the construction of large tower block estates, such as Castle Vale . The Bull Ring was reconstructed and New Street station was redeveloped. In the decades following World War II, the ethnic makeup of Birmingham changed significantly, as it received waves of immigration from

Birmingham has a temperate maritime climate ( Cfb according to the Köppen climate classification ), like much of the British Isles, with average maximum temperatures in summer (July) being around 21.3 °C (70.3 °F); and in winter (January) around 6.7 °C (44.1 °F). Between 1971 and 2000 the warmest day of the year on average was 28.8 °C (83.8 °F) and
4110-442: A wide variety of specialised and highly skilled trades, encouraged exceptional levels of creativity and innovation; this provided an economic base for prosperity that was to last into the final quarter of the 20th century. The Watt steam engine was invented in Birmingham. The resulting high level of social mobility also fostered a culture of political radicalism which, under leaders from Thomas Attwood to Joseph Chamberlain ,

4384-499: Is a first order effect and therefore classified as a radiative forcing by the IPCC . An increase in cloud droplet number due to the introduction of aerosol acts to reduce the cloud droplet size, as the same amount of water is divided into more droplets. This has the effect of suppressing precipitation, increasing the cloud lifetime, known as the cloud lifetime aerosol effect, second indirect effect or Albrecht effect. This has been observed as

Labour replaced the previous no overall control status at the May 2012 elections. The honour and dignity of
4658-428: Is also dependent upon air flow rates and the partial pressure of the gases in the inspired air. The fate of a specific contaminant is dependent upon the form in which it exists (aerosol or particulate). Inhalation also depends upon the breathing rate of the subject. Another complexity not entirely documented is how the shape of PM can affect health, except for the needle-like shape of asbestos fibres which can lodge in
4795-409: Is classified as the direct effect. It encompasses many individual mechanisms, and in general is more poorly defined and understood than the direct and indirect aerosol effects. For instance, if absorbing aerosols are present in a layer aloft in the atmosphere, they can heat surrounding air which inhibits the condensation of water vapour, resulting in less cloud formation. Additionally, heating a layer of

It should be distinguished from organic carbon (OC): clustered or aggregated organic molecules on their own or permeating an EC buckyball. Black carbon from fossil fuels is estimated by the IPCC in the Fourth Assessment Report of the IPCC, 4AR, to contribute
5069-810: Is defined according to European emissions standards , with the Birmingham scheme adopting class D of the A–D classification system. The idea of road pricing in the United Kingdom dates back to 1964, when the Smeed Report proposed that road users should pay the costs roads impose on society. After the London Congestion Charge Zone (CCZ) was introduced in 2003, around 30 other local authorities were expected to follow suit, although most, including Birmingham, failed to bring forward firm proposals at that time. In an interview with The Guardian that year, transport writer and commentator Christian Wolmar suggested this
5206-672: Is highest near the source of emission. Any information regarding DPM and the atmosphere, flora, height, and distance from major sources is useful to determine health effects. Particulate matter emissions are highly regulated in most industrialized countries. Due to environmental concerns , most industries are required to operate some kind of dust collection system. These systems include inertial collectors ( cyclonic separators ), fabric filter collectors (baghouses) , electrostatic filters used in facemasks, wet scrubbers , and electrostatic precipitators . Cyclonic separators are useful for removing large, coarse particles and are often employed as

To the immediate south west of the city lie the Lickey Hills , Clent Hills and Walton Hill , which reach 1,033 feet (315 m) and have extensive views over
5480-727: Is mainly because the presence of sulfate and nitrate causes the aerosols to increase to a size that scatters light effectively. Organic matter (OM) found in aerosols can be either primary or secondary, the latter part deriving from the oxidation of volatile organic compounds (VOCs); organic material in the atmosphere may either be biogenic or anthropogenic . Organic matter influences the atmospheric radiation field by both scattering and absorption. Some aerosols are predicted to include strongly light-absorbing material and are thought to yield large positive radiative forcing . Some secondary organic aerosols (SOAs) resulting from combustion products of internal combustion engines, have been identified as
5617-851: Is no safe level of particulates. Worldwide, exposure to PM 2.5 contributed to 4.1 million deaths from heart disease, stroke, lung cancer, chronic lung disease, and respiratory infections in 2016. Overall, ambient particulate matter is one of the leading risk factor for premature death globally. Human activities generate significant amounts of particulates. For example: Some types of dust, e.g., ashes , soot , paint , glass , plastic and dust from certain man-made fibres, which are brittle and break easily (can fragment and "proliferate"), can pose greater threats and irritations to humans. Those with sharp edges may be even more problematic. The number, shapes, stickiness, etc. of particulates may also be altered by different meteorological conditions. Human-made (anthropogenic) aerosols account for about 10 percent of

The zone covers the urban area inside the A4540 Middleway ring road , excluding the road itself, but including the Jewellery Quarter , the Chinese Quarter , the main shopping district, the area around Birmingham New Street railway station, and the rest of Birmingham city centre . Noncompliant vehicles that enter the zone are charged £8 per day (for private cars, taxis and vans) or £50 per day (for HGVs, coaches, and buses), with no charge for other vehicles. Compliance
10275-686: The amount of small aerosols from fires and human activities is greater there than in the Southern Hemisphere. Overland, patches of large-radius aerosols appear over deserts and arid regions, most prominently, the Sahara Desert in North Africa and the Arabian Peninsula, where dust storms are common. Places where human-triggered or natural fire activity is common (land-clearing fires in the Amazon from August–October, for example, or lightning-triggered fires in
10412-620: The area during the Bronze Age , when a substantial but short-lived influx of population occurred between 1700 BC and 1000 BC, possibly caused by conflict or immigration in the surrounding area. During the 1st-century Roman conquest of Britain , the forested country of the Birmingham Plateau formed a barrier to the advancing Roman legions, who built the large Metchley Fort in the area of modern-day Edgbaston in AD ;48, and made it
10549-479: The atmosphere relative to the surface results in a more stable atmosphere due to the inhibition of atmospheric convection . This inhibits the convective uplift of moisture, which in turn reduces cloud formation. The heating of the atmosphere aloft also leads to a cooling of the surface, resulting in less evaporation of surface water. The effects described here all lead to a reduction in cloud cover i.e. an increase in planetary albedo. The semi-direct effect classified as
10686-462: The borough are designated as green belt , as a portion of the wider West Midlands Green Belt. This is a strategic local government policy used to prevent urban sprawl and preserve greenfield land . Areas included are the aforementioned Sutton Park; land along the borough boundary by the Sutton Coldfield, Walmley and Minworth suburbs; Kingfisher, Sheldon, Woodgate Valley country parks; grounds by
10823-465: The city became increasingly dependent on the motor industry . The recession of the early 1980s saw Birmingham's economy collapse, with unprecedented levels of unemployment and outbreaks of social unrest in inner-city districts. Since the turn of the 21st century, many parts of Birmingham have been transformed, with the redevelopment of the Bullring Shopping Centre , the construction of
10960-531: The city centre. However, a Birmingham University study published in August 2023 found the zone had produced more "modest, but significant reductions in NO 2 of up to 7.3%", but "no detectable impact in the concentrations of fine particles , PM2.5 – the air pollutant with greatest health effects". In the first two years of the scheme's operation, Birmingham City Council raised £79 million from it in fees and penalties. Some of
11097-565: The city via the Cheshire gap on north westerly airstreams, but can also come off the North Sea from north easterly airstreams. Extreme weather is rare, but the city has been known to experience tornadoes . On 14 June 1931, an extremely damaging T6/F3 tornado struck the city, carving an 11-mile damage path through Hollywood, Hall Green, Sparkbrook, Tyseley, Greet and Small Heath, causing extensive damage and killing 1 woman. On 23 November 1981, during
11234-521: The city. Birmingham is drained only by minor rivers and brooks, primarily the River Tame and its tributaries the Cole and the Rea . Birmingham is located significantly inland, and its nearest body of sea is at Liverpool Bay . It lies at the same latitude as Lowestoft , Britain's easternmost settlement; it is therefore much more proximate to the western coast of Wales, at Cardigan Bay . The City of Birmingham forms
11371-451: The climate of the Earth by changing the amount of incoming solar radiation and outgoing terrestrial longwave radiation retained in the Earth's system. This occurs through several distinct mechanisms which are split into direct, indirect and semi-direct aerosol effects. The aerosol climate effects are the biggest source of uncertainty in future climate predictions. The Intergovernmental Panel on Climate Change (IPCC) stated in 2001: While
11508-549: The coldest night typically fell to −9.0 °C (15.8 °F). Some 11.2 days each year rose to a temperature of 25.1 °C (77.2 °F) or above and 51.6 nights reported an air frost. The highest recorded temperature recorded at the Edgbaston Campus was 37.4 °C (99.3 °F), whilst a temperature of 37.0 °C (98.6 °F) was recorded at Birmingham Airport on the city's eastern edge, both recorded on 19 July 2022 . Like most other large cities, Birmingham has
11645-473: The composition of sea water , and thus include magnesium , sulfate , calcium , potassium , and others. In addition, sea spray aerosols may contain organic compounds like fatty acids and sugars, which influence their chemistry. Some secondary particles derive from the oxidation of primary gases such as sulfur and nitrogen oxides into sulfuric acid (liquid) and nitric acid (gaseous) or from biogenic emissions. The precursors for these aerosols—i.e.
11782-457: The cooling from sulfate pollution while minimizing the negative effects on health through deploying in the stratosphere , where only a fraction of the current sulfur pollution would be needed to avoid multiple degrees of warming, but the assessment of costs and benefits remains incomplete, even with hundreds of studies into the subject completed by the early 2020s. Black carbon (BC), or carbon black, or elemental carbon (EC), often called soot,
11919-474: The creation of a planned market town and seigneurial borough within his demesne or manorial estate, around the site that became the Bull Ring . This established Birmingham as the primary commercial centre for the Birmingham Plateau at a time when the area's economy was expanding rapidly, with population growth nationally leading to the clearance, cultivation and settlement of previously marginal land. Within
12056-548: The currently present aerosols is between 0.1 °C (0.18 °F) to 0.7 °C (1.3 °F); the IPCC Sixth Assessment Report uses the best estimate of 0.5 °C (0.90 °F), with the uncertainty mainly caused by contradictory research on the impacts of aerosols of clouds . Some are certain that they cool the planet, though, and this led to solar geoengineering proposals known as stratospheric aerosol injection , which seeks to replicate and enhance
12193-507: The dirty air through a scrubbing solution (usually a mixture of water and other compounds) allowing the particulate to attach to the liquid molecules. Electrostatic precipitators electrically charge the dirty air as it passes through. The now charged air then passes through large electrostatic plates which attract the charged particle in the airstream collecting them and leaving the now clean air to be exhausted or recirculated. For general building construction, some places that have acknowledged
12330-466: The early 20th century. The earliest methods included relatively crude Ringelmann charts , which were grey-shaded cards against which emissions from smokestacks could be visually compared, and deposit gauges , which collected the soot deposited in a particular location so it could be weighed. Automated, modern methods of measuring particulates include optical photodetectors , tapered element oscillating microbalances , and Aethalometers . Besides measuring
12467-459: The exchange of knowledge between pure science and the practical world of manufacturing and technology. This created a "chain reaction of innovation", forming a pivotal link between the earlier Scientific Revolution and the Industrial Revolution that would follow. Birmingham's explosive industrial expansion started earlier than that of the textile-manufacturing towns of the North of England , and
12604-613: The fabric of privilege to its base" in 1832 led John Bright to make Birmingham the platform for his successful campaign for the Second Reform Act of 1867, which extended voting rights to the urban working class. The original Charter of Incorporation , dated 31 October 1838, was received in Birmingham on 1 November, then read in the Town Hall on 5 November with elections for the first Birmingham Town Council being held on 26 December. Sixteen Aldermen and 48 Councillors were elected and
12741-458: The first importance" in the development of the mechanised cotton industry . In 1741 they opened the world's first cotton mill in Birmingham's Upper Priory. In 1746 John Roebuck invented the lead chamber process , enabling the large-scale manufacture of sulphuric acid , and in 1780 James Keir developed a process for the bulk manufacture of alkali , together marking the birth of the modern chemical industry . In 1765 Matthew Boulton opened
12878-426: The first time the manufacturing capacity of human society from the limited availability of hand, water and animal power, this was arguably the pivotal moment of the entire Industrial Revolution and a key factor in the worldwide increases in productivity over the following century. Birmingham rose to national political prominence in the campaign for political reform in the early 19th century, with Thomas Attwood and
13015-627: The focus of a network of Roman roads . Birmingham was then later established by the Beormingas around the 6th or 7th century as a small settlement in the then heavily forested Arden region in Mercia . The development of Birmingham into a significant urban and commercial centre began in 1166, when the Lord of the Manor Peter de Bermingham obtained a charter to hold a market at his castle , and followed this with
13152-407: The forests of northern Canada in Northern Hemisphere summer) are dominated by smaller aerosols. Human-produced (fossil fuel) pollution is largely responsible for the areas of small aerosols over developed areas such as the eastern United States and Europe, especially in their summer. Satellite measurements of aerosols, called aerosol optical thickness, are based on the fact that the particles change
13289-521: The former forest. Birmingham is dominated by the Birmingham Fault, which runs diagonally through the city from the Lickey Hills in the south west, passing through Edgbaston and the Bull Ring, to Erdington and Sutton Coldfield in the north east. To the south and east of the fault the ground is largely softer Mercia Mudstone , interspersed with beds of Bunter pebbles and crossed by the valleys of
13426-562: The gases from which they originate—may have an anthropogenic origin (from biomass and fossil fuel combustion ) as well as a natural biogenic origin. In the presence of ammonia , secondary aerosols often take the form of ammonium salts; i.e. ammonium sulfate and ammonium nitrate (both can be dry or in aqueous solution ); in the absence of ammonia, secondary compounds take an acidic form as sulfuric acid (liquid aerosol droplets) and nitric acid (atmospheric gas). Secondary sulfate and nitrate aerosols are strong light-scatterers . This
13563-486: The ground by gravity in a matter of hours. The smallest particles (less than 1 micrometer) can stay in the atmosphere for weeks and are mostly removed by precipitation . There are evidence that aerosols can "travel across the ocean". For example, in September 2017 wildfires burning across the western United States and Canada, and the smoke was found to have arrived over the United Kingdom and northern France in three days, as shown by satellite images. Diesel particulate matter
13700-531: The heart of the emergence of industrial society . In 1709 the Birmingham-trained Abraham Darby I moved to Coalbrookdale in Shropshire and built the first blast furnace to successfully smelt iron ore with coke , transforming the quality, volume and scale on which it was possible to produce cast iron . In 1732 Lewis Paul and John Wyatt invented roller spinning , the "one novel idea of
13837-494: The industry's products. By the 1600s Birmingham formed the commercial hub of a network of forges and furnaces stretching from South Wales to Cheshire and its merchants were selling finished manufactured goods as far afield as the West Indies . These trading links gave Birmingham's metalworkers access to much wider markets, allowing them to diversify away from lower-skilled trades producing basic goods for local sale, towards
13974-476: The later expansion of the Anglo-Saxon population, in some cases possibly on earlier British sites. There is evidence of early human activity in the Birmingham area dating back to around 8000 BC, with Stone Age artefacts suggesting seasonal settlements, overnight hunting parties and woodland activities such as tree felling. The many burnt mounds that can still be seen around the city indicate that modern humans first intensively settled and cultivated
14111-522: The latter also housing the mini zoo, Birmingham Wildlife Conservation Park . The 2021 census recorded 1,144,900 people living in Birmingham, an increase of around 6.7% from 2011 when 1,073,045 were recorded. It is the 27th largest city in Europe by population within its city boundary. Birmingham's continuous urban area extends beyond the city's boundaries: the Birmingham Larger Urban Zone ,
14248-562: The local council. The composition and toxicity of aerosols , including particles, depends on their source and atmospheric chemistry and varies widely. Wind-blown mineral dust tends to be made of mineral oxides and other material blown from the Earth's crust ; this particulate is light-absorbing . Sea salt is considered the second-largest contributor in the global aerosol budget, and consists mainly of sodium chloride originated from sea spray ; other constituents of atmospheric sea salt reflect
14385-408: The lungs. Geometrically angular shapes have more surface area than rounder shapes, which in turn affects the binding capacity of the particle to other, possibly more dangerous substances. The table below lists the colours and shapes of some common atmospheric particulates: Composition of particles can vary greatly depending on their sources and how they are produced. For example, dust emitted from
14522-465: The members of the Lunar Society of Birmingham – became influential participants in the circulation of philosophical and scientific ideas among Europe's intellectual elite. The close relationship between Enlightenment Birmingham's leading thinkers and its major manufacturers – in men like Matthew Boulton and James Keir they were often in fact the same people – made it particularly important for
14659-425: The most well-known political figures who have lived in Birmingham. The city established its own university in 1900. The city suffered heavy bomb damage during World War II 's " Birmingham Blitz ". The city was also the scene of two scientific discoveries that were to prove critical to the outcome of the war. Otto Frisch and Rudolf Peierls first described how a practical nuclear weapon could be constructed in
14796-594: The new Library of Birmingham (the largest public library in Europe) and the regeneration of old industrial areas such as Brindleyplace , The Mailbox and the International Convention Centre , as well as the rationalisation of the Inner Ring Road . In 1998 Birmingham hosted the 24th G8 summit . The city successfully hosted the 2022 Commonwealth Games . On 5 September 2023 Birmingham city council issued
14933-591: The north and west. The city absorbed Sutton Coldfield in 1974 and became a metropolitan borough in the new West Midlands county . A top-level government body, the West Midlands Combined Authority , was formed in April 2016. The WMCA holds devolved powers in transport, development planning, and economic growth. The authority is governed by a directly elected mayor , similar to the Mayor of London . Birmingham
15070-528: The north of the city, is the largest urban park in Europe and a national nature reserve . Birmingham Botanical Gardens , located close to the city centre, retains the regency landscape of its original design by J. C. Loudon in 1829, while the Winterbourne Botanic Garden in Edgbaston reflects the more informal Arts and Crafts tastes of its Edwardian origins. Several green spaces within
15207-408: The number of cloud droplets. This leads to more scattering of shortwave radiation i.e. an increase in the albedo of the cloud, known as the cloud albedo effect, First indirect effect or Twomey effect . Evidence supporting the cloud albedo effect has been observed from the effects of ship exhaust plumes and biomass burning on cloud albedo compared to ambient clouds. The Cloud albedo aerosol effect
15344-422: The particulate to collect on the outer surface of the bag and allowing the now clean air to pass through to either be exhausted into the atmosphere or in some cases recirculated into the facility. Common fabrics include polyester and fiberglass and common fabric coatings include PTFE (commonly known as Teflon). The excess dust buildup is then cleaned from the bags and removed from the collector. Wet scrubbers pass
15481-677: The plan in 2019, but the scheme was delayed the following year by the COVID-19 pandemic. An opinion survey of 8000 Birmingham residents published by the Council in June 2020 found "Nearly 80% were in favour of measures to reduce car emissions, with 63% not wanting to return to the levels of pollution we had prior to the pandemic.... [and] 71% of... respondents backing the introduction of Zero Emission Zones to discourage high-polluting cars from entering cities". Although some businesses and local councillors called for
15618-430: The pollution control facilities and retain the videos for one month for future inspections. Besides removing particulates from the source of pollution, they may also be cleaned in the open air (e.g. smog tower , moss wall , and water truck), while other control measures employ the use of barriers. Particulates have been measured in increasingly sophisticated ways since air pollution was first systematically studied in
15755-420: The population were aged between 15 and 64, higher than when compared to the national average of 64.1% in England and Wales. Furthermore, 20.9% of the population were aged under 15, higher than the national average of 17.4% while the population aged over 65 was 13.1%, which was lower than the national average of 18.6% respectively. Birmingham is one of the youngest cities in Europe with 40% of its population below
15892-532: The population were born outside the UK, an increase of 4.5% percentage points from 2011. Figures showed that the five largest foreign-born groups living in Birmingham were born in Pakistan, India, Bangladesh, Romania and Jamaica. In 2011, 57% of primary and 52% of secondary pupils were from non-White British families. As of 2021, 31.6% of school pupils in Birmingham were White , 37.7% were Asian , 12.6% were Black , 9.7% were Mixed race and 8.4% were Other. There
16029-506: The possible health risks of construction dust for decades legally require the relevant contractor to adopt effective dust control measures, although inspections, fines and imprisonments are rare in recent years (for example, two prosecutions with a total fines of HKD$ 6000 in Hong Kong in the year 2021). Some of the mandatory dust control measures include load, unload, handle, transfer, store or dispose of cement or dry pulverized fuel ash in
16166-461: The preindustrial background, is estimated as +0.88 (+0.17, +1.48) W/m ". Volcanoes are a large natural source of aerosol and have been linked to changes in the Earth's climate often with consequences for the human population. Eruptions linked to changes in climate include the 1600 eruption of Huaynaputina which was linked to the Russian famine of 1601–1603 , leading to the deaths of two million, and
16303-465: The presence of sulfur, and SO 2 is converted to sulfate when high humidity and low temperatures are present. This causes reduced visibility and red-orange-yellow colors. Human-produced aerosols such as particle pollution tend to have a smaller radius than aerosol particles of natural origin (such as windblown dust). The false-color maps in the map of distribution of aerosol particles on the right show where there are natural aerosols, human pollution, or
16440-497: The problem some new laws were introduced since 2021. In some towns and cities in New South Wales wood smoke may be responsible for 60% of fine particle air pollution in the winter. There are a few ways to reduce wood smoke, e.g., buying the right wood heater and maintaining it well, choosing the right firewood and burning it the right way. There are also regulations in some countries where people can report smoke pollution to
16577-494: The radiative forcing due to greenhouse gases may be determined to a reasonably high degree of accuracy... the uncertainties relating to aerosol radiative forcings remain large, and rely to a large extent on the estimates from global modeling studies that are difficult to verify at the present time. The direct aerosol effect consists of any direct interaction of radiation with atmospheric aerosols, such as absorption or scattering. It affects both short and longwave radiation to produce
16714-856: The respiratory tract oxidative stress via reactive oxygen species, leading to cellular damage, and systemic effects, such as translocation of ultrafine particles into circulation affects organs beyond the lungs. Exposure to particulate matter is linked to various diseases across body systems, such as respiratory system (asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and rhinosinusitis), cardiovascular system (heart attacks, hypertension, arrhythmias, and atherosclerosis), nervous system (cognitive decline and neurodegenerative diseases), metabolic system (diabetes and metabolic syndrome due to inflammatory pathways). The World Health Organization (WHO) provides guidelines to limit exposure: The site and extent of absorption of inhaled gases and vapors are determined by their solubility in water. Absorption
16851-402: The revenue raised from the scheme was earmarked for green transport projects, including car-free school streets, improvements in cycle paths, and expansion of 20mph zones. In August 2023, The Telegraph reported that the scheme "is piling extra costs onto small businesses", quoting "local entrepreneurs" and residents affected by higher delivery costs and linking the issue to what it described as
16988-447: The rigid paternalism and deference of feudal society , and loyalties to the traditional hierarchies of the established church and aristocracy were weak. The town's reputation for political radicalism and its strongly Parliamentarian sympathies saw it attacked by Royalist forces in the Battle of Birmingham in 1643, and it developed into a centre of Puritanism in the 1630s and as
17125-517: The risk of preterm birth and low birth weight . Sulfate pollution also has a complex relationship with NOx pollution and ozone, reducing the also harmful ground-level ozone , yet capable of damaging the stratospheric ozone layer as well. Once the problem became clear, the efforts to remove this pollution through flue-gas desulfurization measures and other pollution controls were largely successful, reducing their prevalence by 53% and causing healthcare savings valued at $ 50 billion annually in
17262-546: The suppression of drizzle in ship exhaust plume compared to ambient clouds, and inhibited precipitation in biomass burning plumes. This cloud lifetime effect is classified as a climate feedback (rather than a radiative forcing) by the IPCC due to the interdependence between it and the hydrological cycle. However, it has previously been classified as a negative radiative forcing. The Semi-direct effect concerns any radiative effect caused by absorbing atmospheric aerosol such as soot, apart from direct scattering and absorption, which
17399-524: The surface for any pneumatic or power-driven drilling, cutting, polishing or other mechanical breaking operation that causes dust emission, unless there is the operation of an effective dust extraction and filtering device, provide hoarding of not less than 2.4 m in height along the whole length of the site boundary, have hard paving on open area and wash every vehicle that leaves the construction sites. Use of automatic sprinkler equipment, automatic carwash equipment and installation of video surveillance system for
17536-584: The total mass of aerosols in the atmosphere as estimated in 2010. The remaining 90 percent comes from natural sources such as volcanoes , dust storms , forest and grassland fires, living vegetation and sea spray , emitting particulates such as volcanic ash, desert dust, soot and sea salt. In the United Kingdom domestic combustion is the largest single source of PM 2.5 and PM 10 annually, with domestic wood burning in both closed stoves and open fires responsible for 38% of PM 2.5 in 2019. To tackle
17673-422: The total mass of particles per unit volume of air (particle mass concentration), sometimes it is more useful to measure the total number of particles per unit volume of air ( particle number concentration ). This can be done by using a condensation particle counter (CPC). To measure the atomic composition of particulate samples, techniques such as X-ray spectrometry can be used. Atmospheric aerosols affect
17810-593: The town of Tamworth and the city of Lichfield in Staffordshire to the north; the city of Coventry and the towns of Nuneaton , Bedworth , Whitnash , Kenilworth , Rugby, Atherstone , Coleshill , Warwick and Leamington Spa to the east in Warwickshire and the Worcestershire towns of Redditch and Bromsgrove to the south west. As the crow flies, Birmingham lies approximately 100 miles (160 km) north-west of London , 85 miles (137 km) north-east of
17947-430: The town with an unusually high degree of social and economic freedom and initiating a period of transition and growth. The importance of the manufacture of iron goods to Birmingham's economy was recognised as early as 1538, and grew rapidly as the century progressed. Equally significant was the town's emerging role as a centre for the iron merchants who organised finance, supplied raw materials and traded and marketed
18084-441: The way the atmosphere reflects and absorbs visible and infrared light. As shown in this page , an optical thickness of less than 0.1 (palest yellow) indicates a crystal clear sky with maximum visibility, whereas a value of 1 (reddish-brown) indicates very hazy conditions. In general, the smaller and lighter a particle is, the longer it will stay in the air. Larger particles (greater than 10 micrometers in diameter) tend to settle to
18221-817: The wider metropolitan area with a population numbering 3,558,916 in 2019 according to Eurostat. Around 305,688 or 26.7% of the population in 2021 were foreign-born , making it a city with one of the largest migrant populations in Europe . According to figures from the 2021 census, 48.7% of the population was White (42.9% White British , 1.5% White Irish , 4.0% Other White , 0.2% Roma , 0.1% Irish Traveller ), 31% were Asian (17.0% Pakistani , 5.8% Indian , 4.2% Bangladeshi , 1.1% Chinese , 2.9% Other Asian ), 10.9% were Black (5.8% African , 3.9% Caribbean , 1.2% Other Black ), 4.8% of Mixed race (2.2% White and Black Caribbean, 0.4% White and Black African, 1.1% White and Asian, 1.1% Other Mixed), 1.7% Arab and 4.6% of Other ethnic heritage. The 2021 census showed 26.7% of
18358-580: Was because councils feared a backlash from motorists and lobbying groups. The scheme gained new momentum in 2017 after the European Commission warned Birmingham City Council to reduce air pollution by 2020 or face a £60 million fine. In 2018, the Council published a business case for its plan, then costed at £68.7 million. The plan was backed by the British Heart Foundation , which said "In order to protect everyone living in Birmingham, it
18495-418: Was driven by different factors. Instead of the economies of scale of a low-paid, unskilled workforce producing a single bulk commodity such as cotton or wool in large, mechanised units of production, Birmingham's industrial development was built on the adaptability and creativity of a highly paid workforce with a strong division of labour , practising a broad variety of skilled specialist trades and producing
18632-572: Was implemented in 2021, opponents published Facebook advertising urging people to oppose what they described as a "war on motorists" and a "travel tax", while the Birmingham Mail noted how a local MP had branded it a "tax on the poor". The scheme was finally launched on 1 June 2021. In the month after the introduction of the charge, the number of the most polluting vehicles entering the zone each day dropped from 18,787 to just over 11,000, and compliance rose from 73.8% to 80.4%. Around 40,000 drivers
18769-608: Was to give it a political influence unparalleled in Britain outside London and a pivotal role in the development of British democracy. From the summer of 1940 to the spring of 1943, Birmingham was bombed heavily by the German Luftwaffe in what is known as the Birmingham Blitz . The damage done to the city's infrastructure, in addition to a deliberate policy of demolition and new building by planners, led to extensive urban regeneration in subsequent decades. Birmingham's economy
