Abstract

The genotoxicity of industrial soils was evaluated. A single cell electrophoresis assay or comet assay, using eleocyte cells of Eisenia foetida, was performed to assess the genotoxicity of aqueous elutions. These were obtained from industrial soils containing metals. All soil samples meet the environmental quality guidelines for metal concentrations. However, elutions have produced genotoxic effects at dilutions as low as 6%. Total metal concentrations for each aqueous elution could express synergistic effects of these compounds.

摘要

对工业土壤的遗传毒性进行了评估。使用赤子爱胜蚓的血细胞进行单细胞凝胶电泳试验或彗星试验，以评估水提取物的遗传毒性。这些提取物取自含有金属的工业土壤。所有土壤样品的金属浓度均符合环境质量准则。然而，提取物在低至6%的稀释度下就产生了遗传毒性效应。每种水提取物的总金属浓度可能表明了这些化合物的协同效应。
