Gases and airborne particulate matter usually resulting from combustion or venting of chemicals associated with human, industrial or other activities. Pollutants are one of the major causes of deterioration of museum objects.
Things that pollute water, land, and air, such as metals, chemicals, oil, and sediment (soil).
potentially harmful chemicals that are produced or released by human activity.
Pollutants are substances that pollute, especially a waste material that contaminates air, soil or water. Some pollutants can be triggers to an asthma attack. Other pollutants may also be allergens. In either case, the pollutant is an irritant for breathing. However, pollutants can also affect someone with skin allergies, if they come into contact with it.
Substances that destroy the purity of air, water, or land
Substances that enter the environment or become concentrated within it, and that has or may have a detrimental biological effect, whether by natural causes or resulting from human activity.
A substance in excess in an ecosystem or not belonging to an ecosystem.
A contaminating substance.
Anything that lessens or spoils the quality of the water, air, or land that it touches.
materials can include, but are not limited to, trash, paper, plastics, cleaning chemicals, animal waste, yard wastes, used oil, fertilizers, pesticides, sediment, metals, fuels, solvents, detergents and fecal coliform.
Man made elements such as sediment, organic debris, increased temperature, nutrients, chemicals, trash and soil degradation which exceed a water's natural ability to neutralize before changes in the physical, chemical or biological integrity of waters of the state occur.
Unwanted chemicals or contaminants found in the environment. Pollutants can harm human health, the environment, and property. Air pollutants occur as gases, liquid droplets, and solids. Once released into the environment, many pollutants can persist, travel long distances, and move from one environmental medium (e.g., air, water, land) to another.
Any gaseous, chemical, or organic matter that contaminates the atmosphere, soil or water.
Dredged spoil, solid waste, incinerator residue, sewage, garbage, sewage sludge, munitions, chemical wastes, geological materials, radioactive materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt, and industrial, municipal, and agricultural waste discharged into water (Section 502(6) of the Clean Water Act as amended by the Water Quality Act of 1987).
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.
Chemicals, biological substances, particles, or thermal changes, discharged into bodies of water, that are potentially detrimental to the environment.
A potentially harmful agent that occurs in the environment as a result of human actions (Suter 1993).
