title: Lack of mutagenicity of synthetic pyrethroids in Salmonella typhimurium strains and in V79 Chinese hamster cells.
abstract: Seven pyrethroids, i.e., cypermethrin, permethrin, deltamethrin, bioresmethrin, resmethrin, cismethrin and fenvalerate, were not found to be mutagenic in (a) Salmonella typhimurium strains TA100 or TA98 in the presence or absence of a rat liver activation system using the plate incorporation assay and fluctuation tests, or (b) V79 Chinese hamster cells in the presence or absence of hepatocytes.
