Toxic Pollutants: Materials that cause death, disease, or birth defects in organisms that ingest or absorb them. The quantities and exposures necessary to cause these effects can vary widely.
toxic pollutants Materials contaminating the environment that cause death, disease, and birth defects in organisms that ingest or absorb them. The quantities and length of exposure necessary to cause these effects can vary widely.
Marine Pollutant: A material which is listed in appendix B to § 172.
Pollutants emitted by combustion engines on farm and construction equipment, gasoline-powered lawn and garden equipment, and powerboats and outboard motors.
Non-Transient Non-Community Water System ...
Pollutants/Pollution
Unwanted chemicals or other materials found in the air. Pollutants can harm health, the environment and property. Many air pollutants occur as gases or vapors, but some are very tiny solid particles: dust, smoke or soot.
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.
Air pollutants which are not covered by ambient air quality standards but which, as defined in the Clean Air Act, may reasonably be expected to cause or contribute to irreversible illness or death.

National Pollutant Discharge Elimination System (NPDES): A provision of the Clean Water Act which prohibits discharge of pollutants into waters of the United States unless a special permit is issued by EPA, a state, or, where delegated, ...
criteria pollutants Pollutants known to be hazardous to human health. The term derives from the requirement to describe the characteristics and potential health and welfare effects of these pollutants from which standards are set or revised.
Exposure to pollutants on the job is believed to account for about 4 percent of all cancer deaths, while exposure to both man-made and natural environmental pollutants account for another 2 percent.
Photochemical pollutants Chemicals which react photochemically (in the presence of sunlight) to destroy ozone in the stratosphere.
...
Nonthreshold pollutant: Substance or condition harmful to a particular organism at any level or concentration.
Emissions: Pollutants released into the air or waterways from industrial processes, households or transportation vehicles. Air emissions pertain to atmospheric air pollution; water emissions refer to pollutants released into waterways.
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.
NPI = National Pollutant Inventory
nutrients = A substance that provides plants food, includes vitamins and minerals
NWC = National Water Commission; See NWC's Water Dictionary ...
NPDES: National Pollutant Discharge Elimination System. A federal permit authorized by the Clean Water Act, Title IV, which is required for discharge of pollutants to navigable waters of the United States, ...
Acid Rain Rain or any form of precipitation of dilute solutions of strong mineral acids, created by the mixing in the atmosphere of pollutants, typically sulfur dioxide and nitrogen oxides compounds, ...
Near the ground, it is a pollutant that comes from car exhausts, irritating the lungs. ozone layer A thin layer of ozone high in the atmosphere that prevents high energy UV radiation from getting to earth.
photochemical smog Air pollution caused by chemical reactions among various substances and pollutants in the atmosphere.
point source A stationary source or fixed facility from which pollutants are discharged. Compare non-point source. pollutant Any substance introduced into the environment that adversely affects the usefulness of a resource.
Persistent Organic Pollutants (POPs) 7 include two major types: Organochlorines (OCs) as well as Polycyclic Aromatic Hydrocarbons (PAHs). Organochlorines (OCs) are almost always human-made.
ATMOSPHERIC POLLUTION Atmospheric pollution is caused when pollutants released into the atmosphere disturb the natural balance of atmospheric systems in various ways. These disturbances include ozone depletion, acid rain and climate change.
internal loading nutrients or pollutants entering a body of water from its sediments
interstitial spaces small spaces between objects, i.e., such as the spaces between gravels, cobbles, or boulders, or between pieces of large woody debris (LWD).
Most NPS pollution comes from pollutants being washed into a waterbody by rainfall and snowmelt.
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.
Stormwater Management - Water runs more quickly off hard surfaces than it does off unpaved surfaces, and when it runs over parking lots in particular it carries with it many pollutants.

Residual: The amount of a pollutant remaining in the environment after a natural or technological process has taken place, e.g.
emission - release of pollutants into the air from a source.
exposure - contact with a chemical by swallowing, by breathing or by direct contact (such as through the skin or eyes).
Air Pollution: Airborne contaminants or pollutants that adversely affect the environment or human health. A byproduct of the manufacturing process and transportation of goods. Buying eco-friendly products indirectly reduces air pollution.
smog - a dense, discolored radiation fog containing large quanities of soot, ash, and gaseous pollutants such as sulfur dioxide and carbon dioxide, responsible for human respiratory ailments.

The level of selected pollutants set by law that may not be exceeded in outside air. Used to determine the amount of pollutants that may be emitted by industry. ...
Note that anthropogenic emissions of other pollutants - notably sulphate aerosol - exert a cooling effect; this can account for the plateau/cooling seen in the temperature record in the middle of the 20th century [16].
