Rather, they form in ! the air when chief(a) 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.
