What are the two air pollutants?
These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
What 3 are natural pollutants?
Natural air pollutants include radon, fog and mist, ozone, ash, soot, salt spray, and volcanic and combustion gases. Radon is a radioactive gas that seeps from the ground in some areas, and fog and mist are both dense water vapor at ground level that obscures vision.
What are natural pollutants?
A natural pollutant is a pollutant created by substances of natural origin such as volcanic dust, sea salt particles, photochemically formed ozone, and products of forest fibres, among others.
What are 2 common indoor air pollutants?
The most common indoor air pollutants include:
- Asbestos.
- Biological Pollutants.
- Carbon Monoxide.
- Cookstoves and Heaters.
- Formaldehyde.
- Lead (Pb)
- Nitrogen Dioxide (NO2)
- Pesticides.
What are types of pollutants?
Different types of pollutants include:
- Nitrogen oxides (NOx)
- Sulfur oxides (SOx)
- Particulate matter (PM)
- Ground level ozone (O3)
- Volatile organic compounds (VOCs)
- Mercury (Hg)
- Peroxyacyl nitrates (PANs)
- and more.
What are the different types of pollutants?
What are some examples of primary air pollutants?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.
What are the natural resources of air pollution?
natural sources, including volcanic eruptions, windblown dust, sea-salt spray and emissions of volatile organic compounds from plants.
What is a natural indoor air pollutant?
Carbon monoxide – An odorless, colorless gas produced by appliances or heaters that burn natural gas, oil, wood, propane, or kerosene. Radon – An odorless, colorless radioactive gas that comes from the natural breakdown of uranium in rock and soil. It can seep into homes through cracks in the foundation, floors, walls.
What are indoor air pollutants give an example?
Indoor sources specifically include those from combustion (e.g., tobacco products, oil, wood, and coal), building materials (e.g., asbestos-containing insulation and pressed wood products), household cleaning products, radon infiltration, and those biologic (e.g., mold, dust) in their makeup.
What are four examples of air pollutants?
Sources and Effects of the 9 Major Air Pollutants Ozone. Ozone (O 3) is a secondary pollutant gas produced when two primary pollutants react in sunlight and stagnant air. Carbon Monoxide. Carbon Monoxide is a primary pollutant gas that comes from the burning of fossil fuels. Nitrogen Dioxide. Particulate Matter. Sulfur Dioxide. Toxic Air Pollutants. Stratospheric Ozone Depleters. Greenhouse Gases. Lead.
What are the most common air pollutants?
The U.S. Environmental Protection Agency (EPA) has named the six most common air pollutants, which are found all over the United States. These pollutants are ozone, particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide and lead.
What are some natural pollutants?
Natural Sources of Air Pollution. Natural air pollutants include radon, fog and mist, ozone, ash, soot, salt spray, and volcanic and combustion gases.
What is a natural source of air pollution?
Natural sources of air pollution include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity. These natural sources of pollution often soon disperse and thin settling near their locale.
