title: Cytogenetic effect of malathion in in vitro culture of human peripheral blood.
abstract: Chromosomal aberrations, sister-chromatid exchanges and mitotic indices were observed in human peripheral leukocytes, treated with four different concentrations of malathion (0.02, 0.2, 2 and 20 micrograms/ml), an organophosphate pesticide, added to the culture medium at 0, 24 and 48 h after culture initiation. These cultures showed a dose-dependent increase in the frequency of chromosomal aberration as well as sister-chromatid exchanges. There was a significant decrease in mitotic index at all concentrations.
