secondary coil pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground leve l oz one (photochemical smog). Major primar! y pollutants produced by gentleman activity allow: * Sulphur oxide and nitrogen oxide - sulphur dioxide which is produced by volcanoes and in miscellaneous industrial processes. Coal and petroleum consider sulphur compounds, which on further reactions generate acid rain. This is one of the causes for concern everyplace the environmental impact of the use of these fuels as power sources. * degree Celsius monoxide - which is a product by...If you want to grasp a all-inclusive essay, order it on our website: OrderCustomPaper.com
