| 摘 要： | 由电子垃圾不当处理引起的环境污染问题已经引起普遍关注.采用SOS/umu测试方法对我国南方某电子垃圾处理地23个土壤样品的有机提取物的直接和间接遗传毒性进行了初步的评估和筛选.结果表明,在有机提取物最高暴露浓度相当于100mg·well-1时,只有很少一部分样品检出直接遗传毒性,而绝大多数样品的有机提取物经过代谢活化后,表现出遗传毒性.与对照地区土壤相比,从事电子垃圾回收处理的地区土壤中存在间接致突变物质的积累,这可能与当地粗放形式的电子垃圾处理活动有关.

| Abstract: | Contamination caused by primitive E-waste processing activities is one of environmental concerns in China. A total of 23 surface soil organic extracts from an E-waste processing area in Southern China were analyzed to screen and assess direct and indirect genotoxicity levels using SOS/umu test. When exposed to a given amount of extract(corresponding to 100mg·well-1), only several samples showed positive response for direct genotoxicity, but a majority of soil samples showed indirect gentoxicities. Compared with control soils, there was accumulation of indirect mutagens in soils which might be the consequences of primitive E-waste processing activities. |
