Inducibility of aryl hydrocarbon hydroxylase in BALB/c/Ki mice exposed to urban air pollution

Abstract
In two separate experiments BALB/c/Ki mice were exposed to urban air pollution. Mice exposed to clean air served as controls. In both experiments there were no obvious quantitative or qualitative differences in lung or liver tissue examined by light microscopy. In both experiments higher aryl hydrocarbon hydroxylase activities and higher trace metal concentrations were observed in the mice exposed to polluted urban air. These data are interpreted in terms of health hazards of urban air pollutants.
