108-421: Noise pollution , or sound pollution , is the propagation of noise or sound with potential harmful effects on humans and animals. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems. Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Some of
216-512: A Global Framework on Chemicals aiming to reduce pollution was agreed during an international conference in Bonn , Germany. The framework includes 28 targets, for example, to "end the use of hazardous pesticides in agriculture where the risks have not been managed" by 2035. Pollution has a cost. Manufacturing activities that cause air pollution impose health and clean-up costs on the whole of society. A manufacturing activity that causes air pollution

The distraction of anthropogenic noise is possibly distracting the fish, and thereby affecting the escape response and routine swimming of the coral fish. A study conducted on species of coral larvae, which are crucial for the expansion of coral reefs, discovered that the larvae oriented towards
648-552: A factor of calculating optimal levels. While a study puts the global mean loss of life expectancy (LLE; similar to YPLL ) from air pollution in 2015 at 2.9 years (substantially more than, for example, 0.3 years from all forms of direct violence), it also indicated that a significant fraction of the LLE is unavoidable in terms of current economical-technological feasibility such as aeolian dust and wildfire emission control. In markets with pollution, or other negative externalities in production,
756-503: A grasshopper is dependent on its ability to attract a mating partner. Male Corthippus biguttulus grasshoppers attract females by using stridulation to produce courtship songs. The females produce acoustic signals that are shorter and primarily low frequency and amplitude, in response to the male's song. Research has found that this species of grasshopper changes its mating call in response to loud traffic noise. Lampe and Schmoll (2012) found that male grasshoppers from quiet habitats have
864-914: A health risk to animals. Motor vehicle emissions are one of the leading causes of air pollution. China , United States , Russia , India Mexico , and Japan are the world leaders in air pollution emissions. Principal stationary pollution sources include chemical plants , coal-fired power plants , oil refineries , petrochemical plants, nuclear waste disposal activity, incinerators, large livestock farms (dairy cows, pigs, poultry, etc.), PVC factories, metals production factories, plastics factories, and other heavy industry . Agricultural air pollution comes from contemporary practices which include clear felling and burning of natural vegetation as well as spraying of pesticides and herbicides. About 400 million metric tons of hazardous wastes are generated each year. The United States alone produces about 250 million metric tons. Americans constitute less than 5% of
972-449: A lesser degree, fish. In the past few years, scientists have shifted to conducting studies on invertebrates and their responses to anthropogenic sounds in the marine environment. This research is essential, especially considering that invertebrates make up 75% of marine species, and thus compose a large percentage of ocean food webs. Of the studies that have been conducted, a sizable variety in families of invertebrates have been represented in
1080-622: A local frequency maximum of about 7319 Hz. In contrast, male grasshoppers exposed to loud traffic noise can create signals with a higher local frequency maximum of 7622 Hz. The higher frequencies are produced by the grasshoppers to prevent background noise from drowning out their signals. This information reveals that anthropogenic noise disturbs the acoustic signals produced by insects for communication. Similar processes of behavior perturbation, behavioral plasticity, and population level shifts in response to noise likely occur in sound-producing marine invertebrates, but more experimental research

#17328450834871296-701: A physiological or behavioral response was triggered. Most of the time, this related to stress, and provided concrete evidence that marine invertebrates detect and respond to noise. Some of the most informative studies in this category focus on hermit crabs. In one study, it was found that the behavior of the hermit crab Pagurus bernhardus , when attempting to choose a shell, was modified when subjected to noise. Proper selection of hermit crab shells strongly contributes to their ability to survive. Shells offer protection against predators, high salinity and desiccation. However, researchers determined that approach to shell, investigation of shell, and habitation of shell, occurred over
1404-404: A population's evolutionary trajectory by selecting traits, sapping resources normally devoted to other activities and thus leading to profound genetic and evolutionary consequences. Several reasons have been identified relating to hypersensitivity in invertebrates when exposed to anthropogenic noise. Invertebrates have evolved to pick up sound, and a large portion of their physiology is adapted for
1512-427: A shorter time duration with anthropogenic noise as a factor. This indicated that assessment and decision-making processes of the hermit crab were both altered, even though hermit crabs are not known to evaluate shells using any auditory or mechanoreception mechanisms. In another study that focused on Pagurus bernhardus and the blue mussel, ( Mytilus edulis) physical behaviors exhibited a stress response to noise. When

And since most of the plastics do not biodegrade in any meaningful sense, all that plastic waste could exist for hundreds or even thousands of years. If plastic production is not circumscribed, plastic pollution will be disastrous and will eventually outweigh fish in oceans. Carbon dioxide , while vital for photosynthesis ,
1836-859: A source, while vision is limited to tens of meters underwater. As anthropogenic noises continue to increase, doubling every decade, this compromises the survivability of marine species. One study discovered that as seismic noises and naval sonar increases in marine ecosystems, cetacean , such as whales and dolphins, diversity decreases. Noise pollution has also impaired fish hearing, killed and isolated whale populations, intensified stress response in marine species, and changed species' physiology. Because marine species are sensitive to noise, most marine wildlife are located in undisturbed habitats or areas not exposed to significant anthropogenic noise, limiting suitable habitats to forage and mate. Whales have changed their migration route to avoid anthropogenic noise, as well as altering their calls. For many marine organisms, sound
1944-424: A typical U.S. population showed that chronic exposure to moderately high levels of environmental noise contributes to hearing loss. Noise exposure in the workplace can also contribute to noise-induced hearing loss and other health issues. Occupational hearing loss is one of the most common work-related illnesses in the U.S. and worldwide. It is less clear how humans adapt to noise subjectively. Tolerance for noise

High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease . In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss. Researchers measure noise in terms of pressure , intensity , and frequency . Sound pressure level (SPL) represents
2268-464: Is an example of a negative externality in production. A negative externality in production occurs "when a firm's production reduces the well-being of others who are not compensated by the firm." For example, if a laundry firm exists near a polluting steel manufacturing firm, there will be increased costs for the laundry firm because of the dirt and smoke produced by the steel manufacturing firm. If external costs exist, such as those created by pollution,

Noise pollution is associated with several health conditions, including cardiovascular disorders, hypertension , high stress levels, tinnitus , hearing loss, sleep disturbances, and other harmful effects. According to a 2019 review of
2592-688: Is for reproduction purposes, navigation, or to notify others of prey or predators. However, anthropogenic noises inhibit species from detecting these sounds, affecting overall communication within the population. Species such as birds, amphibians, reptiles, fishes, mammals, and invertebrates are examples of biological groups that are impacted by noise pollution. If animals cannot communicate with one another, this would result in reproduction to decline (not able to find mates), and higher mortality (lack of communication for predator detection). European robins living in urban environments are more likely to sing at night in places with high levels of noise pollution during
2700-513: Is frequently independent of decibel levels. Murray Schafer's soundscape research was groundbreaking in this regard. In his work, he makes compelling arguments about how humans relate to noise on a subjective level, and how such subjectivity is conditioned by culture. Schafer notes that sound is an expression of power in material culture. As such, fast cars or Harley Davidson motorcycles with aftermarket pipes tend to have louder engines not only for safety reasons, but for expressions of power by dominating
2808-447: Is important that policymakers attempt to balance these indirect benefits with the costs of pollution in order to achieve an efficient outcome. It is possible to use environmental economics to determine which level of pollution is deemed the social optimum. For economists, pollution is an "external cost and occurs only when one or more individuals suffer a loss of welfare". There is a socially optimal level of pollution at which welfare
2916-419: Is in keeping children and elderly healthy. Noise generated by traffic, ships, vehicles, and aircraft can affect the survivability of wildlife species and can reach undisturbed habitats. Although sounds are commonly present in the environment, anthropogenic noises are distinguishable due to differences in frequency and amplitude. Many animals use sounds to communicate with others of their species, whether that

Several metrics describing noise exposure include: Researchers with the US National Park Service found that human activity doubles the background-noise levels in 63 percent of protected spaces like national parks, and increases them tenfold in 21 percent. In the latter places, "if you could have heard something 100 feet away, now you can only hear it 10 feet away," Sound can be measured in
3132-436: Is maximized. This is because consumers derive utility from the good or service manufactured, which will outweigh the social cost of pollution until a certain point. At this point the damage of one extra unit of pollution to society, the marginal cost of pollution, is exactly equal to the marginal benefit of consuming one more unit of the good or service. Moreover, the feasibility of pollution reduction rates could also be

3456-645: Is now noisy and chaotic due to ships, oil drilling, sonar equipment, and seismic testing. The principal anthropogenic noise sources come from merchant ships, naval sonar operations, underwater explosions (nuclear), and seismic exploration by oil and gas industries. Cargo ships generate high levels of noise due to propellers and diesel engines. This noise pollution significantly raises the low-frequency ambient noise levels above those caused by wind. Animals such as whales that depend on sound for communication can be affected by this noise in various ways. Higher ambient noise levels also cause animals to vocalize more loudly, which

This includes regularly sound produced or perceived in the context of aggression or predator avoidance. Invertebrates also utilize sound to attract or locate mates, and often employ sound in the courtship process. Many of the studies that were conducted on invertebrate exposure to noise found that
8208-512: The main sources of noise in residential areas include loud music , transportation (traffic, rail, airplanes, etc.), lawn care maintenance, construction , electrical generators, wind turbines, explosions and people. Documented problems associated with noise in urban environments go back as far as ancient Rome . Research suggests that noise pollution in the United States is the highest in low-income and racial minority neighborhoods, and noise pollution associated with household electricity generators
8316-404: The manufacturer will choose to produce more of the product than would be produced if the manufacturer were required to pay all associated environmental costs. Because responsibility or consequence for self-directed action lies partly outside the self, an element of externalization is involved. If there are external benefits, such as in public safety , less of the good may be produced than would be
8424-410: The most frequent soil contaminants. A series of press reports published in 2001, culminating in the publication of the book Fateful Harvest, revealed a widespread practise of recycling industrial leftovers into fertilizer, resulting in metal poisoning of the soil. Ordinary municipal landfills are the source of many chemical substances entering the soil environment (and often groundwater), emanating from
8532-451: The nation $ 537–$ 678 billion annually. In the US, deaths caused by coal pollution were highest in 1999, but decreased sharply after 2007. The number dropped by about 95% by 2020, as coal plants have been closed or have scrubbers installed. In 2019, water pollution caused 1.4 million premature deaths. Contamination of drinking water by untreated sewage in developing countries is an issue, for example, over 732 million Indians (56% of
8640-508: The natural marine soundscape. Noise from shipping and small boats is at the same frequency as sounds generated by marine organisms, and therefore acts as a disruptive element in the sound environment of coral reefs. Both longer-term and acute effects have been documented on coral reefs organisms after exposure to noise pollution. Anthropogenic noise is essentially a persistent stressor on coral reefs and its inhabitants. Both temporary and permanent noise pollution has been found to induce changes in
8748-554: The natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard. The usefulness of the natural resource is usually impaired by the presence of pollutants and contaminants." In contrast, the United Nations considers pollution to be the "presence of substances and heat in environmental media (air, water, land) whose nature, location, or quantity produces undesirable environmental effects." The major forms of pollution are listed below along with
8856-471: The natural sound environment of the coral reefs. Anthropogenic sources of noise are generated by a range of different human activities, such as shipping , oil and gas exploration and fishing. The principal cause of noise pollution on coral reefs is boat and ship activities. The use of smaller motorboats, for purposes as fishing or tourism within coral reef areas, and larger vessels, such as cargo ships transporting goods, significantly amplifies disturbances to
8964-624: The noise around them. Therefore, it is suggested that marine invertebrates are likely perceiving the effects of noise differently than marine mammals. It is reported that invertebrates can detect a large range of sounds, but noise sensitivity varies substantially between each species. Generally, however, invertebrates depend on frequencies under 10 kHz. This is the frequency at which a great deal of ocean noise occurs. Therefore, not only does anthropogenic noise often mask invertebrate communication, but it also negatively impacts other biological system functions through noise-induced stress. Another one of
9072-439: The particular contaminants relevant to each of them: One of the most significant natural sources of pollution are volcanoes , which during eruptions release large quantities of harmful gases into the atmosphere. Volcanic gases include carbon dioxide, which can be fatal in large concentrations and contributes to climate change , hydrogen halides which can cause acid rain , sulfur dioxides, which are harmful to animals and damage
9180-1348: The population) and over 92 million Ethiopians (92.9% of the population) do not have access to basic sanitation . In 2013 over 10 million people in India fell ill with waterborne illnesses in 2013, and 1,535 people died, most of them children. As of 2007 , nearly 500 million Chinese lack access to safe drinking water. Acute exposure to certain pollutants can have short and long term effects. Oil spills can cause skin irritations and rashes . Noise pollution induces hearing loss , high blood pressure , stress , and sleep disturbance . Mercury has been linked to developmental deficits in children and neurologic symptoms. Older people are significantly exposed to diseases induced by air pollution . Those with heart or lung disorders are at additional risk. Children and infants are also at serious risk. Lead and other heavy metals have been shown to cause neurological problems, intellectual disabilities and behavioural problems. Chemical and radioactive substances can cause cancer and birth defects . The health impacts of pollution have both direct and lasting social consequences. A 2021 study found that exposure to pollution causes an increase in violent crime. A 2019 paper linked pollution to adverse school outcomes for children. A number of studies show that pollution has an adverse effect on
9288-550: The presence of many horses in concentrated areas made the cities the primary sources of pollution. King Edward I of England banned the burning of sea-coal by proclamation in London in 1272, after its smoke became a problem; the fuel was so common in England that this earliest of names for it was acquired because it could be carted away from some shores by the wheelbarrow . The Industrial Revolution gave birth to environmental pollution as we know it today. London also recorded one of
9396-414: The prevention of urban runoff . Policy , law and monitoring/transparency/ life-cycle assessment -attached economics could be developed and enforced to control pollution. A review concluded that there is a lack of attention and action such as work on a globally supported "formal science – policy interface", e.g. to " inform intervention, influence research, and guide funding". In September 2023
9504-465: The productivity of both indoor and outdoor workers. Pollution has been found to be present widely in the natural environment . A 2022 study published in Environmental Science & Technology found that levels of anthropogenic chemical pollution have exceeded planetary boundaries and now threaten entire ecosystems around the world. There are a number of effects of this: To protect
9612-458: The purpose of detecting environmental vibrations. Antennae or hairs on the organism pick up particle motion. Anthropogenic noise created in the marine environment, such as pile driving and shipping, are picked up through particle motion; these activities exemplify near-field stimuli. The ability to detect vibration through mechanosensory structures is most important in invertebrates and fish. Mammals, also, depend on pressure detector ears to perceive
9720-555: The quality of the soil and water . The pollution comes from the type of conduct of chemical treatments used e.g., in pretreatment, dyeing, printing, and finishing operations that many or most market-driven companies use despite "eco-friendly alternatives". Textile industry wastewater is considered to be one the largest polluters of water and soil ecosystems , causing "carcinogenic, mutagenic, genotoxic, cytotoxic and allergenic threats to living organisms". The textile industry uses over 8000 chemicals in its supply chain, also polluting
9828-665: The required standards set by the International Electrotechnical Commission (IEC) and in the United States, the American National Standards Institute as type 0, 1, or 2 instruments. Type 0 devices are not required to meet the same criteria expected of types 1 and 2 since scientists use these as laboratory reference standards. Type 1 (precision) instruments are to study the precision of capturing sound measurements, while type 2 instruments are for general field use. Type 1 devices acceptable by
9936-404: The research. A variation in the complexity of their sensory systems exists, which allows scientists to study a range of characteristics and develop a better understanding of anthropogenic noise impacts on living organisms. Even marine invertebrates, such as crabs ( Carcinus maenas ), have been shown to be negatively affected by ship noise. Larger crabs were noted to be negatively affected more by
10044-483: The responses recorded are similar to those identified when faced with a predator, it is implied that the squid initially viewed the sounds as a threat. However, it was also noted that the alarm responses decreased over a period of time, signifying that the squid had likely acclimated to the noise. Regardless, it is apparent that stress occurred in the squid, and although further investigation has not been pursued, researchers suspect that other implications exist that may alter
10152-574: The same loudness level. The most commonly used weighted levels are A-weighting , C-weighting, and Z-weighting. A-weighting mirrors the range of hearing, with frequencies of 20 Hz to 20,000 Hz. This gives more weight to higher frequencies and less weight to lower frequencies. C-weighting has been used to measure peak sound pressure or impulse noise, similar to loud short-lived noises from machinery in occupational settings. Z-weighting, also known as zero-weighting, represents noise levels without any frequency weights. Understanding sound pressure levels
10260-441: The sea hare to determine the effects of boat noise on the early stages of life and the development of embryos. Researchers have studied sea hares from the lagoon of Moorea Island , French Polynesia. In the study, recordings of boat noise were made by using a hydrophone. In addition, recordings of ambient noise were made that did not contain boat noise. In contrast to ambient noise playbacks, mollusks exposed to boat noise playbacks had
10368-418: The sound of healthy reefs. The noise created by anthropogenic activities could mask this soundscape, hindering the larvae from swimming towards the reef. Noise pollution ultimately poses a threat to the behavioral patterns of several coral organisms. Terrestrial anthropogenic noise affects the acoustic communications in grasshoppers while producing sound to attract a mate. The fitness and reproductive success of
10476-416: The sounds than smaller crabs. Repeated exposure to the sounds did lead to acclimatization . Underwater noise pollution due to human activities is also prevalent in the sea, and given that sound travels faster through water than through air, is a major source of disruption of marine ecosystems and does significant harm to sea life, including marine mammals, fish and invertebrates. The once-calm sea environment
10584-765: The soundscape are indicative of class differences in urban environments. Noise pollution can have negative affects on adults and children on the autistic spectrum . Those with Autism Spectrum Disorder (ASD) can have hyperacusis, which is an abnormal sensitivity to sound. People with ASD who experience hyperacusis may have unpleasant emotions, such as fear and anxiety, and uncomfortable physical sensations in noisy environments with loud sounds. This can cause individuals with ASD to avoid environments with noise pollution, which in turn can result in isolation and negatively affect their quality of life. Sudden explosive noises typical of high-performance car exhausts and car alarms are types of noise pollution that can affect people with ASD. While
10692-591: The soundscape with a particular sound. Other key research in this area can be seen in Fong's comparative analysis of soundscape differences between Bangkok, Thailand, and Los Angeles, California, US. Based on Schafer's research, Fong's study showed how soundscapes differ based on the level of urban development in the area. He found that cities in the periphery have different soundscapes than inner city areas. Fong's findings tie not only soundscape appreciation to subjective views of sound, but also demonstrates how different sounds of
10800-652: The squid's survival habits. An additional study examined the impact noise exposure had on the Indo-Pacific humpbacked dolphin ( Sousa chinensis ). The dolphins were exposed to elevated noise levels due to construction in the Pearl River Estuary in China, specifically caused by the world's largest vibration hammer—the OCTA-KONG. The study suggested that while the dolphin's clicks were not affected, their whistles were because of susceptibility to auditory masking . The noise from
10908-415: The standards have a margin of error of ±1.5 dB, while type 2 instruments meet a margin of error of ±2.3 dB. Sound can also be measured using a noise dosimeter, a device similar to a sound level meter. Individuals have used dosimeters to measure personal exposure levels in occupational settings given their smaller, more portable size. Unlike many sound level meters, a dosimeter microphone attaches to
11016-818: The threshold of hearing; this results in decibel units on the logarithmic scale. The logarithmic scale accommodates the vast range of sound heard by the human ear. Frequency, or pitch, is measured in Hertz (Hz) and reflects the number of sound waves propagated through the air per second. The range of frequencies heard by the human ear range from 20 Hz to 20,000 Hz; however, sensitivity to hearing higher frequencies decreases with age. Some organisms, such as elephants, can register frequencies between 0 and 20 Hz (infrasound), and others, such as bats, can recognize frequencies above 20,000 Hz (ultrasound) to echolocate. Researchers use different weights to account for noise frequency with intensity, as humans do not perceive sound at
11124-535: The top contributors to human death , beyond being a major driver of climate change whereby greenhouse gases are considered per se as a form of pollution (see above ) . Society derives some indirect utility from pollution; otherwise, there would be no incentive to pollute. This utility may come from the consumption of goods and services that inherently create pollution (albeit the level can vary) or lower prices or lower required efforts (or inconvenience) to abandon or substitute these goods and services. Therefore, it
11232-589: The wide variety of refuse accepted, especially substances illegally discarded there, or from pre-1970 landfills that may have been subject to little control in the U.S. or EU. There have also been some unusual releases of polychlorinated dibenzodioxins , commonly called dioxins for simplicity, such as TCDD . Pollution can also occur as a result of natural disasters. Hurricanes, for example, frequently result in sewage contamination and petrochemical spills from burst boats or automobiles. When coastal oil rigs or refineries are involved, larger-scale and environmental damage
11340-465: The worker and monitors levels throughout a work shift. Additionally, dosimeters can calculate the percent dose or time-weighted average (TWA). In recent years, scientists and audio engineers have been developing smartphone apps to conduct sound measurements, similar to the standalone sound level meters and dosimeters. In 2014, the National Institute for Occupational Safety and Health (NIOSH) within
11448-475: The world, that depend on the reefs for the services they provide, such as fishing and tourism. The reefs contribute substantially to global biodiversity and productivity, and is a critical part of the support systems of the earth. Anthropogenic noise, originating from human activities, has increased underwater noise in the natural sound environment of the reefs. The preeminent sources of noise pollution on coral reefs are boat and ship activities. The sound created by
11556-458: The world. Pollutants frequently have outsized impacts on vulnerable populations, such as children and the elderly, and marginalized communities, because polluting industries and toxic waste sites tend to be collocated with populations with less economic and political power. This outsized impact is a core reason for the formation of the environmental justice movement , and continues to be a core element of environmental conflicts , particularly in
11664-492: The worst in Europe. August Bebel recalled conditions before a modern sewer system was built in the late 1870s: Waste-water from the houses collected in the gutters running alongside the curbs and emitted a truly fearsome smell. There were no public toilets in the streets or squares. Visitors, especially women, often became desperate when nature called. In the public buildings the sanitary facilities were unbelievably primitive....As
