Air pollution is a mixture of solid particles and gases in the air. Many activities pollute the air we breathe, including driving cars and trucks; burning coal, oil, and other fossil fuels; and even such everyday activities as dry cleaning, painting operations, and filling your car with gas. When these gases and particles accumulate in the air in high enough concentrations, they can harm us and our environment. The Clean Air Act, first passed in 1970, was created to clean up air pollution and help protect the health of all Americans.
