Induction of sister-chromatid exchanges in cultured human lymphocytes by Aldicarb, a carbamate pesticide

Abstract

The aim of this work was to investigate the effects of Aldicarb on human lymphocytes in vitro in the presence of an exogenous metabolic activation system. This was done by means of an analysis of SCE and mitotic delay. CP was used to compare the chromosomal effects of Aldicarb with a known genotoxic agent. Our experiments showed that Aldicarb as well as CP induced a significant increase of SCE values in the absence of S9 mix. In vitro metabolic activation of both chemicals increased the SCE values. The addition of a metabolic system slightly decreased the successive mitotic progression of cells in culture.
