Rather, they form in ! the air when primary pollutants react or interact. An important deterrent example of a secondary pollutant is ground level ozone  one of the umteen secondary pollutants that make up photochemical smog. Some pollutants may be both primary and secondary: that is, they are both emitted directly and formed from other primary pollutants. Major primary pollutants produced by human activity include: * Sulfur oxides (SOx) - especially entropy dioxide, a chemical...If you want to get a intact essay, tack it on our website: OrderCustomPaper.com
