Mutation spectra in Salmonella of complex mixtures: comparison of urban air to benzo[a]pyrene.

Environmental and molecular mutagenesis - 1 Jan 1994

DeMarini D M, Shelton M L, Bell D A

Abstract excerpt

We used an ion-exchange procedure coupled to the Salmonella assay to fractionate the dichloromethane-extractable particulate organics from an urban air sample collected in Boise, Idaho. A resulting base/neutral fraction contained 81% of the mutagenic activity but only 36% of the mass of the unfractionated sample. Chemical analysis showed that polycyclic aromatic hydrocarbons (PAHs) accounted for much of the...
