Air Pollutant: Any substance in the air that could, in high enough concentration, harm man, other animals, vegetation, or material. Pollutants may include almost any natural or artificial composition of airborne matter capable of being airborne.
A group of air pollutants classified under the US Clean Air Act as dangerous to human health and detrimental to the environment. Among the Clean Air Act's list of hazardous pollutants are: asbestos, benzene, mercury and vinyl chloride.
National Emissions Standards for Hazardous Air Pollutants (NESHAPS)
Emissions standards set by EPA for an air pollutant not covered by NAAQS that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
Air Pollutant: Any unwanted substance in air.
Algae: Simple rootless plants that grow in sunlit waters in proportion to how many nutrients are available.
Air Pollutants: Amounts of foreign and/or natural substances occurring in the atmosphere that may result in adverse effects to humans, animals, vegetation, and/or materials. (See also air pollution.) ...

Criteria Air Pollutants - The Six Major Air Pollutants
INFO-AD ...
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 (CO) produced as a byproduct of combustion; ...
Air pollutants that are not covered by ambient air quality standards but which, as defined in the Clean Air Act, may present a threat of adverse human health effects or adverse environmental effects.
Air pollutants for which standards for safe levels of exposure have been set under the Clean Air Act. Current criteria pollutants are sulfur dioxide, particulate matter, carbon monoxide, nitrogen oxides, ozone and lead.
Cumulative impact ...
Air Pollutants can travel long distances from their source. During this transport, secondary pollutants such as acid rain and ozone are produced. Tree foliage may act as a filter, concentrating the pollution.
An air pollutant which is neither a criteria nor hazardous pollutant, as described in the Clean Air Act, but for which new source performance standards exist.
An air pollutant consisting of small particles with an aerodynamic diameter less than or equal to a nominal 10 micrometer (about 1/7 the diameter of a single human hair).
Hazardous Air Pollutants- Air pollutants which are not covered by ambient air quality standards but which, as defined in the Clean Air Act, may present a threat of adverse human health effects or adverse environmental effects.
Hazardous Air Pollutants (HAP's) - air pollutants, as defined by the Clean Air Act, that present a threat to human health and/or the environment. Pollutants include asbestos, beryllium, mercury, benzene, etc.
Hazardous air pollutants-Air pollutants that may reasonably be expected to cause or contribute to irreversible illness or death as defined under the Clean Air Act.
The movement of air pollutant from one place to the other by wind.
Atom
The smallest particles of an element that can exist either alone or in combination, considered a source of vast potential energy.
HAPs Hazardous air pollutants.
Hardness The sum of the divalent cation concentrations expressed as meq/L or mg calcium carbonate per liter [mg CaCO3/L].
Air Pollutant: Any substance in air that could, in high enough concentration, be harmful. Pollutants may include solids, liquids, gases or any combination thereof. Air pollutants are often grouped in categories for ease in classification.

Certain kinds of air pollutants, like ozone, can make asthma and other lung conditions worse. Ozone found high in the atmosphere is called "good ozone" because it protects life on Earth from the sun's harmful ultraviolet rays.
The EPA's rationale for deregulating lead as an air pollutant is like a case study for convoluted logic.

Designated Pollutant- An air pollutant which is neither a criteria nor hazardous pollutant, as described in the Clean Air Act, but for which new source performance standards exist.
In an emissions trading program, sources of a particular pollutant (most often an air pollutant) are given permits to release a specified number of tons of the pollutant.
For an air pollutant, this is the additional lifetime cancer risk occurring in a hypothetical population in which all individuals are exposed continuously from birth throughout their lifetimes to a concentration of 1 microgram per cubic meter (μ ...
Fugitive Emissions: Air pollutants released to the air other than those from stacks or vents; typically small releases from leaks in plant equipment such as valves, pump seals, flanges, sampling connections, etc.
photochemical oxidants Air pollutants formed by the action of sunlight on oxides of nitrogen and hydrocarbons. photochemical smog Air pollution caused by chemical reactions of various pollutants emitted from different sources.
Best available control technology An emission limitation, including a visible emissions standard, based on the maximum possible reduction of an air pollutant.
Billet A bar of steel or iron that is in an intermediate manufacturing stage.
The 3M company in the USA, over a 10-year period, eliminated 10 000 tonnes of water pollutants, 90 000 tonnes of air pollutants and 140 000 tonnes of sludge, saving over $192 million at the same time.
VOC (volatile organic compound): The term used to describe the organic gases and vapours that are present in the air. They are believed to be involved in ground-level ozone formation. Some VOCs are toxic air pollutants.
chemicals include gasoline, industrial chemicals such as benzene, solvents such as toluene and xylene, and tetrachloroethylene (perchloroethylene, the principal dry cleaning solvent). Many volatile organic chemicals are also hazardous air pollutants.
