DNA Damage Caused By Pesticide-contaminated Soil

摘要

To determine the DNA damaging potential and the genotoxicity of individual compounds in pesticide contaminated soil. Methods In the present study, DNA damaging potential of pesticide-contaminated soil and the genotoxicity of individual compounds present in the soil were assessed using fluorimetric analysis of DNA unwinding assay. Results The contaminated soil sample showed 79% (P<0.001) of DNA strand break, whereas technical grade of major carbaryl andα-naphthol constituents of the contaminated soil showed 64% (P<0.01) and 60% (P<0.02) damage respectively. Conclusion Our results indicate that the toxicity caused by contaminated soil is mainly due to carbaryl andα-napthol, which are the major constituents of the soil sample analyzed by GC-MS.
