What will be an ideal response?


Suspended particulate matter (PM): Sources are soot, smoke, metals, and carbon from combustion; dust, salts, metal, and dirt from wind erosion; and atmospheric reactions of gases. Volatile organic compounds (VOC): Sources are incomplete combustion of fossil fuels; evaporation of solvents and gasoline; and emissions from plants. Carbon monoxide (CO): Sources are incomplete combustion of fuels. Nitrogen oxides (NOx): Source is from nitrogen gas due to high combustion temperatures when burning fuels. Sulfur oxides (SOx): Source is primarily from the combustion of sulfur-containing fuels. Lead: Sources are combustion of leaded fuels and solid wastes. Air toxics: Sources are industry and transportation. Radon: Sources are rocks and soil; natural breakdown of radium and uranium.
