Abstract
Ethylcarbamate has a clear genotoxic potential in Drosophila melanogaster. In the somatic mutation and recombination test (SMART) it induces, in a dose-dependent manner, single spots as well as twin spots. The twin spots indicate a recombinogenic activity of ethyl carbamate. A strong strain difference demonstrates that the metabolic activation of ethyl carbamate to DNA binding metabolites most probably also in Drosophila involves cytochrome P450-dependent enzyme activities.
