摘要
本文对太原市污灌区水质、土壤和作物中Hg、Cd、As三种元素的污染状况进行了研究.结果表明,二坝灌区水质属轻度污染;土壤中Hg和Cd含量超过背景值;土壤与作物中三种元素的含量之间存在一定的相关性,其中Hg的相关系数为显著水平.
The polluted situation of mercury, cadmium and arsonium in irrigation water, soils and crops in sewage irrigation area of Tanyuan has been discussed. The results of experiment show that the water quality of second dam irrigation area has been lightly polluted , the content of mercury and cadmium in the soils has exceeded background value.
