From Wikipedia


A pollutant is a waste material that pollutes air, water or soil, and is the cause of pollution.

Three factors determine the severity of a pollutant: its chemical nature, its concentration and its persistence. Some pollutants are biodegradable and therefore will not persist in the environment in the long term. However the degradation products of some pollutants are themselves polluting such as the products DDE and DDD produced from degradation of DDT

Types of pollutants

Stock pollutants

Pollutants that the environment has little or no absorptive capacity are called stock pollutants (e.g. persistent synthetic chemicals, non-biodegradable plastics, and heavy metals). Stock pollutants accumulate in the environment over time. The damage they cause increases as more pollutant is emitted, and persists as the pollutant accumulates. Stock pollutants can create a burden for future generations by passing on damage that persists well after the benefits received from incurring that damage have been forgotten.

Fund pollutants

Fund pollutants are those for which the environment has some absorptive capacity. Fund pollutants do not cause damage to the environment unless the emission rate exceeds the receiving environment's absorptive capacity (e.g. carbon dioxide, which is absorbed by plants and oceans). Fund pollutants are not destroyed, but rather converted into less harmful substances, or diluted/dispersed to non-harmful concentrations.

Notable pollutants

Notable pollutants include the following groups:

Zones of influence

Pollutants can also be defined by their zones of influence, both horizontally and vertically.

Horizontal zone

The horizontal zone refers to the area that is damaged by a pollutant. Local pollutants cause damage near the emission source. Regional pollutants cause damage further from the emission source.

Vertical zone

The vertical zone is referred to whether the damage is ground-level or atmospheric. Surface pollutants cause damage by concentrations of the pollutant accumulating near the Earth's surface Global pollutants cause damage by concentrations in the atmosphere



Pollutants can cross international borders and therefore international regulations are needed for their control. The Stockholm Convention on Persistent Organic Pollutants, which entered into force in 2004, is an international legally binding agreement for the control of persistent organic pollutants. Pollutant Release and Transfer Registers (PRTR) are systems to collect and disseminate information on environmental releases and transfers of toxic chemicals from industrial and other facilities.

European Union

The European Pollutant Emission Register is a type of PRTR providing access to information on the annual emissions of industrial facilities in the Member States of the European Union, as well as Norway.

United States

Clean Air Act standards. Under the Clean Air Act, the National Ambient Air Quality Standards (NAAQS) are standards developed for outdoor air quality. The National Emissions Standards for Hazardous Air Pollutants are emission standards that are set by the Environmental Protection Agency (EPA) which are not covered by the NAAQS.

Clean Water Act standards. Under the Clean Water Act, EPA promulgated national standards for municipal sewage treatment plants, also called publicly owned treatment works, in the Secondary Treatment Regulation. National standards for industrial dischargers are calledEffluent guidelines(for existing sources) andNew Source Performance Standards, and currently cover over 50 industrial categories. In addition, the Act requires states to publish water quality standards for individual water bodies to provide additional protection where the national standards are insufficient.

RCRA standards. The Resource Conservation and Recovery Act (RCRA) regulates the management, transport and disposal of municipal solid waste, hazardous waste and <

Question:Okay I have a pollution prject due soon and I need to know the following stuff... What is it made of? How does it pollute? What is its effect on humans? how long until it decomposes? How can we solve tis type of pollution project? I need this info for A Soda can and a glass bottle. First person to answer these and have a sourcce will get 10 points. :) Anything helps thanks!

Answers:i knw you can recycle glass,and metal to make other things which does not decompose carbon dioxide is bad pollution witch kills the ozone layer that mostly comes from cars you can get radiation from trash burner plants try google for better info this is the best i can do


Answers:Air pollution is a broad term applied to all physical (particulate matter), chemical, and biological agents that modify the natural characteristics of the atmosphere. Some definitions also consider physical perturbations such as noise pollution, heat, radiation or light pollution as air pollution.[citation needed] Definitions commonly include the term harmful as a requisite to consider a change to the atmosphere as pollution. Air pollutants are classified as either primary or secondary; a primary air pollutant is one that is emitted directly to the air from a given source, such as the Carbon monoxide produced as a byproduct of combustion, whereas a secondary air pollutant is formed in the atmosphere through chemical reactions involving primary air pollutants. The formation of ozone in photochemical smog is an example of a secondary air pollutant. The atmosphere is a complex, dynamic and fragile system. Concern is growing about the global effects of air pollutant emissions, especially global warming. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health.

Question:what are the different types of air pollution and how is it measured?

Answers:what causes air pollution is when a a power station uses coal to make electricity. when the coal is burned it releases Nox and Sox ( nitrus oxide, and sulphur oxide) into the atmosphere. This cause air pollution and acid rain. air pollution can be meased by a carbon menoxide measurer, or even by the amount of weathering on statues due to acid rain.

Question:My final for science is presenting a globa earth issue. I told my teacher that I wanted to do water pollution, but she told me what kind.. i didn't know there were even types of water pollution. Can any of you guys tell the types of water pollution and a description for each type that I can choose? Thank you

Answers:Well, that topic can be divided up in different ways. Like this: - Type of water resource - lakes, rivers, ground water, sea water - Type of pollutant - say, bacterial, chemical, organic, pesticides, fertilizers - Source of pollutant - industry, farming, sewage treatment plants. Contamination from farming might be a manageable sized topic. Nitrate and phosphorus are the big items there. You can find a lot of information on how those get into the water, and the possible affects they have, including health problems from drinking water with high nitrates and the problem of the "dead zone" in the Gulf of Mexico caused by runoff of ag chemicals. Another good one might be bacterial contamination of surface water. Dysentary is the biggest killer of babies in the world, and it is caused by water that is contaminated by bacteria from human and animal waste. The history of that is interesting and the fact that it is still so rampant in undeveloped countries is very important for us all to know. Good luck with this. I think there is a lot of info on the web to help you.

Types of Pollution. Noise Pollution, Air Pollution :Pollution is of six types. Many types of pollution can be noticed simultaneously like air pollution and noise pollution. This video was shot in a small city in North India. There is a nonstop row of automobile vehicles crossing the small city causing Noise Pollution due to horns and sound of vehicles,Air Pollution dhe to emissions from vehicles.

The Different Types Of Air Pollution :pollutioncontrol.free-health-care.info The Different Types Of Air Pollution According to the Environmental Protection Agency there are a great number of types of air pollution. These are all classifieds as different levels and threats to the environment in regards to how they are controlled and as to what level is allowed to be produced before it is considered as threatening to the environment. Because of the different types and health concerns brought on by the different types of air pollution, it is leading to an increase in healthcare costs across the board. polluters The different types of air pollution start as small not as threatening issues or pollutants and will range to more devastating and dangerous levels based on what it is that is being released into the air. One of the biggest polluters that are regulated by the United States EPA are those of large industries. If they are companies that produce sulfur dioxide and oxides of nitrogen. Since these are primarily power plants and manufacturing areas. These are regulated under the Clean Air Act and are regulated by the EPA. different types of air pollution There are different things that can be done in order to prevent and reduce the different types of air pollution. One of the biggest threats is Carbon Monoxide as a threat and that is a primary pollutant that is produced by cars. There are now regulations in place that reduce the emissions that are produced by cars and other Carbon Monoxide producing items. Using ...
