Air pollution causes 1 in 8 deaths worldwide and is the largest single environmental health crisis we face.
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog. Some air pollutants are poisonous.
