Toxicological evaluation of carcinogenicity of the pyrethroid imiprothrin in rats and mice

Abstract The carcinogenic potential of a non-genotoxic pyrethroid imiprothrin was examined in rats and mice. There was no carcinogenicity in rats up to a maximum dose of 5000 ppm of the diet. There was a higher (p = 0.03) incidence of lung adenocarcinomas at 7000 ppm in males, and females showed an increasing (p
