Assesment of the Genotoxic Effect of the Diazinon on Root Cells of Allium cepa (L.)

ABSTRACT Organophosphorous pesticides (OPs) posses a great potential of acute toxicity for exposed animals and men. To evaluate the toxic potential of the organophosphate diazinon on root meristematic cells of Allium cepa L., was created two groups: In group 1 (control group), was not given any chemical. In group 2 (diazinon-treatment group), different doses (10, 40, 80 and 160 ppm) and times periods (24, 48 and 72 h) were administered. After exposure, cell death, effective concentration (EC50), mitotic index, cellular /chromosome aberrations, DNA damage by comet assay and RAPD-PCR were assess...
