An air pollutant, which exists in solid form, is;- *
Answers
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
Answer:
Air pollutants cause air pollution in high concentrations. They can take the form of solid particles (such as particulate matter, which is composed of solid or liquid particles from unburnt matter emitted from combustion), liquid droplets (such as acid rain), gases (such as sulfur dioxide and carbon monoxide), or a combination thereof (including some forms of particulate matter that are made up of solid or liquid molecules suspended in gas). Air pollutants come from natural and human sources, and natural and human activity can increase air pollutant concentrations to a level that may cause visibility problems, health problems in people, and/or damage natural ecosystems.[1]
Naturally occurring pollutants include ash, soot, sulfur dioxide, ground-level ozone (also known as smog), salt spray, volcanic and combustion gases, and radon. These pollutants are released during volcanic eruptions, forest fires, and grass fires. Human-caused pollutants include naturally occurring pollutants released from human activity: carbon monoxide, sulfur dioxide, nitrogen dioxide, and particulate matter. They are released from coal, oil, and natural gas use, electric power plants, factories, and motor vehicles.
