Frequency of sister chromatid exchange in peripheral lymphocytes of male pesticide applicators.
In the present study 61 male pesticide applicators who worked in cotton fields and regularly sprayed pesticides such as DDT, BHC, endosulfan, malathion, methyl parathion, phosphamidon, dimethoate, monocrotophos, quinalphos fenvelrate, and cypermethrin were analyzed for sister chromatid exchanges, mitotic index, and cell cycle kinetics in peripheral lymphocytes. Subjects who handled pesticides were non-smokers and teetotalers and the data were compared with the matched control group. Statistical analysis revealed that the frequency of sister chromatid exchanges was significantly higher among the pesticide applicators at all the durations of exposure when compared to controls. Subjects exposed to pesticides also showed cell cycle delay and decrease in mitotic index when compared to the control group.
