| 摘 要： | 本文测定了山西太原污灌区农田土壤中汞污染状况 ,并采用盆栽模拟的方法 ,研究了汞污染对土壤酶活性、土壤有效磷含量、小麦产量以及地下水质的影响 ,结果表明污水灌区土壤中汞的累积量明显高于清水灌区 ,随着汞污染程度的加重 ,对土壤酶活性及小麦生长的抑制作用也增强 ,长期利用污水灌溉 ,土壤中汞会下移 ,从而对浅层地下水造成污染

| Abstract: | We investigated the effect of waste water irrigation on soil enzyme activity, soil available phosphate content, wheat yield, and groundwater quality by pot experiments. The results showed that the mercury content in the waste-water irrigated area was significantly higher than that in the clean water irrigated area. As pollution degree increased, the inhibition effect of mercury on soil enzyme activity and wheat growth became stronger. Long-term irrigation by using waste-water, mercury could be leached from soil, thus resulting in to groundwater pollution. |
