33-462: The World Plumbing Council (WPC) is an international organization of plumbing associations and plumbing industry participants . There are currently over 200 WPC members from more than 30 countries around the world. World Plumbing Day is an international event on March 11 every year, initiated by the WPC as a means of highlighting the role plumbing plays in health, safety and sustainability. The WPC hosts

66-412: A build-up of gases inside the gut, prompting the sphincter to relieve the pressure and release the feces. After an animal has digested eaten material, the remains of that material are discharged from its body as waste. Although it is lower in energy than the food from which it is derived, feces may retain a large amount of energy, often 50% of that of the original food. This means that of all food eaten,

99-493: A certification exam. There is no federal law establishing licenses for plumbers. In Canada, licensing requirements differ by province; however, the provinces have pooled resources to develop an Interprovincial Program Guide that developed and now maintains apprenticeship training standards across all provinces. The Red Seal Program, formally known as the Interprovincial Standards Red Seal Program,

132-433: A deterrent for humans, as consuming or touching it may result in sickness or infection. Feces are discharged through the anus or cloaca during defecation . This process requires pressures that may reach 100 millimetres of mercury (3.9 inHg) (13.3 kPa) in humans and 450 millimetres of mercury (18 inHg) (60 kPa) in penguins. The forces required to expel the feces are generated through muscular contractions and

165-409: A plant in having fruit is that animals will eat the fruit and unknowingly disperse the seed in doing so. This mode of seed dispersal is highly successful, as seeds dispersed around the base of a plant are unlikely to succeed and often are subject to heavy predation . Provided the seed can withstand the pathway through the digestive system, it is not only likely to be far away from the parent plant, but

198-477: A significant amount of energy remains for the decomposers of ecosystems. Many organisms feed on feces, from bacteria to fungi to insects such as dung beetles , who can sense odors from long distances. Some may specialize in feces, while others may eat other foods. Feces serve not only as a basic food, but also as a supplement to the usual diet of some animals. This process is known as coprophagia , and occurs in various animal species such as young elephants eating

231-470: A valuable purpose in paleontology because they provide direct evidence of the predation and diet of extinct organisms. Coprolites may range in size from a few millimetres to more than 60 centimetres. Palaeofeces are ancient feces , often found as part of archaeological excavations or surveys. Intact paleofeces of ancient people may be found in caves in arid climates and in other locations with suitable preservation conditions. These are studied to determine

264-413: Is a program that sets common standards to assess the skills of tradespeople across Canada. The Red Seal, when affixed to a provincial or territorial trade certificate, indicates that a tradesperson has demonstrated the knowledge required for the national standard in that trade. National Vocational Qualifications ( NVQ ) remained the main form of plumbing qualification until they were superseded in 2008 by

297-502: Is among the world's most expensive coffees. Paper is also made from elephant dung in Thailand. Haathi Chaap is a brand of paper made from elephant dung. Dog feces was used in the tanning process of leather during the Victorian era . Collected dog feces, known as "pure", "puer", or "pewer", were mixed with water to form a substance known as "bate", because proteolytic enzymes in

330-536: Is burned as fuel in many countries. Animals such as the giant panda and zebra possess gut bacteria capable of producing biofuel. The bacterium in question, Brocadia anammoxidans , can be used to synthesize the rocket fuel hydrazine . A coprolite is fossilized feces and is classified as a trace fossil . In paleontology they give evidence about the diet of an animal. They were first described by William Buckland in 1829. Prior to this, they were known as "fossil fir cones " and " bezoar stones". They serve

363-494: Is called constipation . The appearance of human fecal matter varies according to diet and health. Normally it is semisolid, with a mucus coating. A combination of bile and bilirubin , which comes from dead red blood cells , gives feces the typical brown color. After the meconium , the first stool expelled, a newborn's feces contains only bile , which gives it a yellow-green color. Breast feeding babies expel soft, pale yellowish, and not quite malodorous matter; but once

396-427: Is even provided with its own fertilizer. Organisms that subsist on dead organic matter or detritus are known as detritivores , and play an important role in ecosystems by recycling organic matter back into a simpler form that plants and other autotrophs may absorb once again. This cycling of matter is known as the biogeochemical cycle . To maintain nutrients in soil it is therefore important that feces returns to

429-535: Is no singular form, making the word a plurale tantum ; out of various major dictionaries, only one enters variation from plural agreement . "Feces" is used more in biology and medicine than in other fields (reflecting science 's tradition of classical Latin and Neo-Latin ) There are many synonyms in informal registers for feces, just like there are for urine . Many are euphemistic , colloquial , or both; some are profane (such as shit ), whereas most belong chiefly to child-directed speech (such as poo or

462-470: Is relatively high in paleofeces, making it more reliable than skeletal DNA retrieval. The reason this analysis is possible at all is due to the digestive system not being entirely efficient, in the sense that not everything that passes through the digestive system is destroyed. Not all of the surviving material is recognizable, but some of it is. Generally, this material is the best indicator archaeologists can use to determine ancient diets, as no other part of

495-517: Is the scientific terminology, while the term stool is also commonly used in medical contexts. Outside of scientific contexts, these terms are less common, with the most common layman's term being poop or poo . The term shit is also in common use, although it is widely considered vulgar or offensive. There are many other terms, see below. The word faeces is the plural of the Latin word faex meaning "dregs". In most English-language usage , there

528-562: Is used as a cement to make adobe ( mudbrick ) huts, or even in throwing sports, especially with cow and camel dung. Kopi luwak , or civet coffee, is coffee made from coffee beans that have been eaten and excreted by Asian palm civets ( Paradoxurus hermaphroditus ). Giant pandas provide fertilizer for the world's most expensive green tea . In Malaysia , tea is made from the droppings of stick insects fed on guava leaves. In northern Thailand , elephants are used to digest coffee beans in order to make Black Ivory coffee , which

561-441: The diet and health of the people who produced them through the analysis of seeds, small bones, and parasite eggs found inside. Feces may contain information about the person excreting the material as well as information about the material. They also may be analyzed chemically for more in-depth information on the individual who excreted them, using lipid analysis and ancient DNA analysis. The success rate of usable DNA extraction

594-504: The palindromic word poop ) or to crude humor (such as crap , dump , load and turd .). The feces of animals often have special names (some of them are slang), for example: In all human cultures, feces elicit varying degrees of disgust in adults. Children under two years typically have no disgust response to it, suggesting it is culturally derived. Disgust toward feces appears to be strongest in cultures where flush toilets make olfactory contact with human feces minimal. Disgust

627-615: The Qualification and Credit Framework (QCF) and then again, in 2015, into the National qualifications frameworks in the United Kingdom . The terms NVQ and SVQ ( Scottish Vocational Qualification ) are still widely used. Plumbers in the United Kingdom are required to pass Level 2 and Level 3 vocational requirements of the City and Guilds of London Institute . There are several regulatory bodies in

660-651: The United Kingdom providing accredited plumbing qualifications, including City and Guilds of London Institute and Pearson PLC . In Ireland, a four-year apprenticeship plus qualification exam was necessary for someone to practice professionally. Accreditation of businesses is of great help in order to show their credibility and experience in the job. Plumbing work is defined in the Australian Standards (AS3500) Regulations 2013 and refers to any operation, work or process in connection with installation, removal, demolition, replacement, alteration, maintenance or repair to

693-670: The World Plumbing Conference once every three years. The last conference was in September 2019 in Melbourne , Australia. Plumber The origin of the word "plumber" dates from the Roman Empire . Roman roofs used lead in conduits and drain pipes and some were also covered with lead; lead was also used for piping and for making baths. The Latin for lead is plumbum . In medieval times, anyone who worked with lead

726-463: The archaeological record is so direct an indicator. A process that preserves feces in a way that they may be analyzed later is the Maillard reaction . This reaction creates a casing of sugar that preserves the feces from the elements. To extract and analyze the information contained within, researchers generally have to freeze the feces and grind it up into powder for analysis. Animal dung occasionally

759-423: The area from which they came, which is not always the case in human society where food may be transported from rural areas to urban populations and then feces disposed of into a river or sea. Depending on the individual and the circumstances, human beings may defecate several times a day, every day, or once every two or three days. Extensive hardening of the feces that interrupts this routine for several days or more

792-514: The baby begins to eat, and the body starts expelling bilirubin from dead red blood cells, its matter acquires the familiar brown color. At different times in their life, human beings will expel feces of different colors and textures. A stool that passes rapidly through the intestines will look greenish; lack of bilirubin will make the stool look like clay. The feces of animals, e.g. guano and manure , often are used as fertilizer . Dry animal dung , such as that of camel , bison and cattle ,

825-431: The case of human feces , fecal transplants or fecal bacteriotherapy are in use. Urine and feces together are called excreta . The distinctive odor of feces is due to skatole , and thiols ( sulfur -containing compounds), as well as amines and carboxylic acids. Skatole is produced from tryptophan via indoleacetic acid. Decarboxylation gives skatole. The perceived bad odor of feces has been hypothesized to be

858-508: The dog feces helped to relax the fibrous structure of the hide before the final stages of tanning. Dog feces collectors were known as pure finders . Elephants, hippos , koalas and pandas are born with sterile intestines, and require bacteria obtained from eating the feces of their mothers to digest vegetation. In India, cow dung and cow urine are major ingredients of the traditional Hindu drink Panchagavya . Politician Shankarbhai Vegad stated that they can cure cancer . Feces

891-534: The eye, and hernias. Working at height or in confined spaces, or working with lead and asbestos are all on-site dangers that plumbers can face. Plumbers risk infections when dealing with human waste while repairing sewage systems. Microbes can be excreted in the faecal matter or vomit of the sufferer onto the toilet or sewage pipes. Human waste can contain infectious diseases such as cholera , typhoid , hepatitis , polio , cryptosporidiosis , ascariasis , and schistosomiasis . The term " White House Plumbers "

924-425: The feces of their mothers to gain essential gut flora , or by other animals such as dogs, rabbits, and monkeys. Feces and urine, which reflect ultraviolet light, are important to raptors such as kestrels , who can see the near ultraviolet and thus find their prey by their middens and territorial markers. Seeds also may be found in feces. Animals who eat fruit are known as frugivores . An advantage for

957-575: The supervision of a fully qualified gas fitter. To obtain a full gas license from the Department of Mines and Energy, the plumber will need to have worked on an interim gas license for a minimum period of twelve months and successfully completed a Certificate IV in Plumbing. There are many types of dangers to a plumber. These include electric shock, strains and sprains, cuts and lacerations, bruises and contusions, fractures, burns and scalds, foreign bodies in

990-463: The system of pipes and fixtures that conveys clean water into and liquid waste out of a building. To become a licensed plumber a four year apprenticeship and a Certificate III in Plumbing is required. As part of this course, instruction in the basics of gas fitting will be undertaken. Upon completion, these basics in gas fitting will allow the plumber to not only apply for their plumbing license but also an interim gas license, and carry out gas work under

1023-526: Was a popular name given to the covert White House Special Investigations Unit established on July 24, 1971, during the presidency of Richard Nixon . Their job was to plug intelligence " leaks " in the U.S. Government relating to the Vietnam War (i.e. the Pentagon Papers ); hence the term "plumbers". Feces Feces ( or faeces ; sg. : faex ) are the solid or semi-solid remains of food that

1056-538: Was not digested in the small intestine , and has been broken down by bacteria in the large intestine . Feces contain a relatively small amount of metabolic waste products such as bacterially altered bilirubin , and dead epithelial cells from the lining of the gut. Feces are discharged through the anus or cloaca during defecation . Feces can be used as fertilizer or soil conditioner in agriculture. They can also be burned as fuel or dried and used for construction . Some medicinal uses have been found. In

1089-862: Was referred to as a plumber; this can be seen from an extract about workmen fixing a roof in Westminster Palace; they were referred to as plumbers: "To Gilbert de Westminster, plumber, working about the roof of the pantry of the little hall, covering it with lead, and about various defects in the roof of the little hall". Years of training and/or experience are needed to become a skilled plumber; some jurisdictions also require that plumbers be licensed. Common plumbing tasks and skills include: Each state and locality may have its own licensing and taxing schemes for plumbers. Some states license journeymen and master plumbers separately, while others license only master plumbers. To become licensed, plumbers must meet standards for training and experience, and in most cases, pass
