Abstract
Directly active mutagens are formed on exposure of the promutagen benzo[ a ]pyrene to gaseous pollutants in smog. In simulated atmospheres containing 1 part per million nitrogen dioxide and traces of nitric acid, directly mutagenic nitro derivatives are readily formed from both benzo[ a ]pyrene and perylene, a nonmutagen in the Ames reversion assay. Possible formation of direct mutagens by such reactions on sample collection filters, in exhaust effluents, and in the atmosphere should be recognized.This publication has 25 references indexed in Scilit:
