How do fossil fuels cause air pollution?

Explanation

Air pollution is the addition of particulate matter, gases and vapours into the atmosphere these have an adverse effect on humans, animals vegetation and human assets. Air pollution is of two main types: 1 Natural (e.g., forest fire, dust storm, pollen), 2. Human made (e.g., burning of fossil or fuels in industries. vehicles and thermoelectric plants, gaseous emission from industries, mining processing, stone crushing). The particulate air pollutants are also called suspended particulate matter or SPM because they remain suspended in air for a good period of time. SPM consists of smokes, soot (a black powder substance that is produced when coal, wood, etc, is burnt), fly ash and dust, (i.e., particles of silica, grit, lead, asbestos, cement, sulphur etc). Gases that causes air pollution are sulphur dioxide, nitrogen oxides, carbon monoxide, hydrogen sulphide, hydrogen cyanides, hydrogen fluorides, chlorine, methane and ammonia. They are formed from nitrogen, sulphur and carbon compounds of tossil fuels and decaying organic matter. pollutant vapours include unburnt hydrocarbons (benzene).
