[The mutagenicity of some insecticides in the Salmonella/microsome test system]

The mutagenic effects of 4 insecticides, i.e., bioallethrin, tetramethrin, propoxur, lethane and three commercial formulation of insecticides i.e. asbo, formulation I, formulation II was determined in a standard Salmonella typhimurium assay with the use of strains TA 98 and TA 100. Bioallethrin was found to be a weak mutagen in the TA 100 and TA 98 strains of S. typhimurium, whereas propoxur, formulation I showed weak mutagenic effects only on S. typhimurium TA 98 strain.
