title: Genotoxicity of the insecticide rotenone in cultured human lymphocytes.
abstract: We have investigated the genotoxic activity of rotenone on three genetic endpoints, sister-chromatid exchanges (SCE), chromosome aberrations (CA) and micronuclei (MN) in human lymphocyte cultures in the presence and absence of a metabolic activation system (S9 mix). Our results indicate that rotenone increases the frequency of binucleated micronucleated (BNMN) cells and causes a delay in the cell cycle but does not increase the frequency of CA and SCE at the concentrations used. The presence of S9 mix reduces the genotoxic activity of rotenone.
