Air pollution Gravity Wiki FANDOM powered by WikiaPollutantsSourcesIndoor Air QualityHealth EffectsReduction EffortsLegal RegulationsStatisticsAtmospheric DispersionEnvironmental ImpactsExternal LinksAn air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or manmade.Pollutants can be classified as either primary or secondary. Usually, primary pollutants are substances directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories.Se...how does gravity settlers reduce air pollution in industries
