An important example of a secondary pollutant is ground level oz 1 (photoc hemical smog). Major primary pollutants pro! duced by mankind activity allow: * Sulphur oxide and nitrogen oxide - sulphur dioxide which is produced by volcanoes and in miscellaneous industrial processes. Coal and petroleum break off 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 impersonate a all-inclusive essay, order it on our website: OrderCustomPaper.com
