Document Summary

Carbon monoxide coal, forest fires: natural: incomplete oxidation of methane, forest fires, anthropogenic: incomplete combustion of fossil fuels, incomplete combustion of. Nitrogen monoxide: natural: lightning, bacterial decomposition of organic matter, anthropogenic: fertilizers, combustion of fossil fuels. Sulfur oxides: natural: volcanoes, sea spray (this is a sulfur-containing aerosol), biological decomposition of organic matter, anthropogenic: process of smelting plants, burning sulfur-containing fossil fuels. Particulates: natural, dust (mechanical breakup of solid water, pollen (from fungal spores, ash (from volcanic eruptions, anthropogenic, soot (incomplete combustion of hydrocarbons in powerstations, arsenic (insectisides, ash (combustion of fossil fuels in furnaces) Co, no, voc"s: minimization, catalytic converters- the exhaust gas is passed over a platinum-based catalyst and aerated. The carbon monoxide is converted into carbon dioxide. The converter also reduces hydrocarbon (voc"s) emissions by reacting it with oxygen and producing carbon dioxide. Anthropogenic: burning of sulfur-containing fossil fuels: s + o2 (cid:224) so2. Smelting plants to make metal oxides: cu2s + 2o2 (cid:224) 2cuo + so2.
