During the past decade, there has been renewed effort examining the extent to which hazardous compounds (particularly mutagens and carcinogens) are found in the urban atmosphere. Most of these studies examined organic material associated with the particles emitted from specific sources. In contrast, few studies have examined the volatile airborne organics before and after they undergo atmospheric transformation. Such studies have shown that the mutagenicity of organic material from combustion sources can dramatically increase after photooxidation processes and that a variety of atmospheric hydrocarbons can be transformed into mutagenic species through these same processes. A review of the Salmonella bioassay genotoxicity of volatile organic pollutants and their atmospheric transformation products is presented.
