the contamination of the atmosphere by the introduction of pollutants from human and natural sources
a small discrete mass of solid or liquid matter that remains individually dispersed in gas or liquid emissions (usually considered to be an atmospheric pollutant)
Small particles of dust released into the atmosphere by many natural processes and human activities
extremely small units of matter
Air pollutants formed as a result of sunlight acting on compounds such as nitrogen oxides and sulfur dioxide.
a gas molecule that is made up of three oxygen atoms
air pollution by a mixture of smoke and fog
A brownish haze that is a mixture of ozone and other chemicals, formed when pollutants react with each other in the presence of sunlight
Los Angeles-type smog
Smog that is dominated by oxidants such as ozone. Also known as Photochemical smog; Brown smog.
Smog that is dominated by oxidants such as ozone. Also known as Photochemical smog; Los Angeles-type smog
Exists in cities that use coal for heat; they are located in cold, moist climates & generally older in terms of development
Does not need sunlight
Smog dominated by sulfur dioxide and sulfate compounds. Also known as Sulfurous smog; Gray smog; Industrial smog.
smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels, especially coal.
Type of air pollution consisting mostly of a mixture of sulfur dioxide, suspended droplets of sulfuric acid formed from some of the sulfur dioxide, and suspended solid particles.
VOCs (volatile organic compounds)
group of primary pollutants that comes from gas, solvents, and evaporating chemicals; component of photochemical smog
pollutants that are put directly into the air by human or natural activity.
pollutants that are formed by the combination of primary pollutants in the atmosphere.
The temperature inversion in which warm air traps cold air and pollutants near the earth.
A layer of air that is warmer than the air below
A long, thin, fibrous silicate mineral with insulating properties, which can cause cancer when inhaled.
sick building syndrome
headaches, allergies, chronic fatigue and other symptoms caused by poorly vented indoor air contaminated by pathogens or toxins
a gas that is the natural decay product of uranium in bedrock; it is a leading cause of lung cancer in non-smokers
