Major Air pollutants
Lead
-
It can be found in all parts of the environment
Much of it comes from burning fossil fuels mining and
manufacturing.
-
Nitrogen Oxides
-
Two of the most toxicologically significant nitrogen oxides are nitric oxide and nitrogen dioxide; both are nonflammable and colorless to brown at room temperature.
-
Sulfur Dioxides
-
Sulfur dioxide is a colorless gas with a pungent odor. It is a liquid when under pressure, and it dissolves in water very easily. Sulfur dioxide in the air comes mainly from activities such as the burning of coal and oil at power plants or from copper smelting.
Toxicological profile
Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance.
Carbon monoxide
Carbon monoxide is a colorless, nonirritating, odorless, and tasteless gas. It is found in both outdoor and indoor air.
-
Ground level ozone
Ozone can be “good” or “bad” for health and the environment depending on where it’s found in the atmosphere.
Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun.
Ground-level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma.
The EPA has identified six pollutants as “criteria” air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels.
