A substance that causes pollution.

Any undesirable solid, liquid or gaseous matter in an environmental medium: "undesirability" is often concentration-dependent, low concentrations of most substances being tolerable or even essential in many cases. (In the context of air pollution, an undesirable modification is one that has injurious or deleterious effects.) A primary pollutant is one emitted into the atmosphere, water, sediments or soil from an identifiable source. A secondary pollutant is a pollutant formed by chemical reaction in the atmosphere, water, sediments, or soil. No entries

any chemical substance from outside an ecosystem, whether natural or man-made, that impacts the biological processes in the ecosystem.

is anything introduced into the environment that causes problems for people or animals. Air pollutants are unwanted chemicals or other materials found in the air, such as grasses, vapors, dust, smoke, or soot. Most pollutants are created as by-products of processes found to be useful.

An environmental contaminant.

waste matter that contaminates the water or air or soil

a discharge into the environment that does, or could, cause adverse impacts on human or ecological health, damage property or cause loss of amenity

a substance in the environment that by direct toxicity or by indirectly harming the ecosystem is considered to be harmful or dangerous to humans

a substance, such as bacteria or sediment, that is identifiable and in some way quantifiable

Solid waste, incinerator residue, pet waste, sewage, garbage, sediment, chemical wastes.

A contaminant at a concentration high enough to endanger the life of organisms.

A harmful substance emitted into the air, water or soil.

a contaminant that negatively impacts the physical, chemical, or biological properties of the environment

a harmful chemical emitted into the air, water, or soil. Pollutants can be solid, liquid, or gas.

any substance that directly or indirectly creates an adverse human health or environmental effect when introduced into any environmental media.

A substance that destroys the purity of air, water, or land.

A contaminant, a substance that is not naturally present in water or occurs in unnatural amounts that can degrade the physical, chemical, or biological properties of the water. Pollutants can be chemicals, disease-producing organisms, silt, toxic metals, oxygen-demanding materials, to name a few.

a liquid, gas, dust, or solid material that causes contamination of air, water, earth, and living organisms.

A substance in certain concentrations that is capable of degrading the environment's usefulness. Many such substances in diluted forms are not harmful to humans or to the environment.

any material that can damage living things or their environments

Any substance defined as such pursuant to the Water Pollution Control Act, N.J.S.A 58:10A- 1 et seq.

A substance, organism or energy form present in amounts that impair or threaten an ecosystem to the extent that its current or future uses are prevented.

Anything in the air, water, or earth that is harmful or interferes with a desired activity (For information on specific pollutants, see section on Pollutants in Long Island Sound)

a chemical or physical component found in water, land or air that makes conditions less favorable for living things (Improper fertilizer application can act as a pollutant.)

Air contaminants that fall in the categories for criteria and non-criteria pollutants. Criteria pollutants are carbon monoxide, particulate matter, nitrogen dioxide, sulfur dioxide, lead and ozone (volatile organic compounds and nitrogen oxides are precursors of ozone). The non-criteria pollutants include fluorides, asbestos, beryllium, mercury, vinyl chloride, sulfuric acid mists, hydrogen sulfide (H2S), total reduced sulfur (including H2S), and reduced sulfur compounds (including H2S). APC Rule 1220-3-9-.01(4)(b) and Rule 1200-3-3, Table 1. For Water Pollution Control, ÒpollutantsÓ are defined as sewage, industrial waste or other wastes. SWP Rule 69-3-103.(21)

any impurity, contaminant, or harmful substance found in the environment

A substance that pollutes air, water or land.

any substance suspended or dissolved in water that builds up in sufficient quantity to impair water quality.

Substance (such as a waste material) that pollutes or contaminates the air, soil, or water and can damage the environment.

Generally are substances introduced into the environment that adversely affect the usefulness of a resource.

A substance that doesn't normally belong somewhere and upsets the surroundings.

A pollutant is something that makes our environment dirty or harmful. Ozone is a pollutant because it makes the air unhealthy to breathe. (Back to Ozone Action! Days)

Any substance introduced into the environment that adversely affects the usefulness of a resource.

A contaminant, such as dredged soil, solid waste, incinerator residue, filter backwash, sewage, garbage, sewage sludge, munitions, chemical wastes, biological materials, or radioactive materials.

In addition to chemical substances,the term also embraces noise, vibration and alterations to the ambient temperature. pore space: The total space not occupied by soil particles in a bulk volume of soil.

Strictly too much of any substance in the wrong place or at the wrong time is a pollutant. More specifically, atmospheric pollution may be defined as 'the presence of substances in the atmosphere, resulting from man-made activities or from natural processes, causing adverse effects to man and the environment'.

A pollutant is any human-made substance that can damage the environment (air, water, or on the land).

Any undesirable solid, liquid or gaseous matter in a solid, liquid or gaseous environmental medium: "undesirability" is often concentration-dependent, low concentrations of most substances being tolerable or even essential in many cases. For the meaning of "undesirable" in air pollution contexts, see "pollution". A primary pollutant is one emitted into the atmosphere, water, sediments or soil from an identifiable source. A secondary pollutant is a pollutant formed by chemical reaction in the atmosphere, water, sediments, or soil. PS contaminant. RT pollution, secondary pollutant. After WHO, 1980
