Micronuclei Induced by Landfill Leachate in Root-Tip Cells of Vicia faba and Early Spermatids of Mice / 环境与健康杂志

ABSTRACT

Objective To study the pollution of organic components in landfill leachates which produced from industrial city-Z and their cytogenetic toxicity. Methods The landfill leachates and groundwater samples collected from an industrial city-Z were analyzed by GC-MS and determined by micronucleus test of the root-tip cells of Vicia faba. The organic extracts of the landfill leachates samples were also determined by micronucleus test of early spermatids of mice exposed to organic extracts to be tested via peritoneal injection. Results Benzene, phenol, B(a)P were found in this two samples. Significantly higher levels of micronucleus rates of the root-tip cells of Vicia faba were observed in the original landfill leachates and diluted samples(1∶10,1∶2)compared with those of the negative samples(P
