PM10 PM10 are particulate with diameters less than 10 um. The major sources of PM10 include dust from road traffic, emission from vehicles, open burning, construction, agriculture, or as a secondary pollutant transformed from other air pollutants. Due to its small size, PM10 can easily penetrate into the bronchus of human lung system. The respiratory system can be damaged by the physical presence of PM10 or by the pollutants that absorbed on the PM10. In addition to the natural occurring sulfur dioxides, sulfur dioxide can be formed during the combustion by combining sulfur in the fuel with oxygen.
Sulfur dioxide is a colorless gas with a very stink odors.
Sulfurous acids can be further oxided into sulfuric acids and become the major sources of acid rain formation. The formation of nitrogen oxides comes from the combustion process. Nitrogen in the air or in the fuel reacts with oxygen and forms nitrogen oxides. Nitrous oxide is a colorless, odorless gas and slightly dissolves in water.
