我国重金属污染土壤的利用研究

检测了重金属污染地区粮食、蔬菜、水果等不同作物的重金属含量。结果表明,这3类作物对高背景值耕地土壤中有害元素吸收能力的顺序为:蔬菜粮食水果。同一地区不同地块采样点土样中重的金属含量有所差异,同一有害元素在不同作物中的积累特性不同,不同作物种类对高背景值元素的吸收差异较大,为合理开发利用被重金属污染的土地资源提供了理论依据。

Application of Pollution Soil by Heave Metal in China

The results of heavy metal contents of grain,vegetables,fruits were tested in the heavy metal contaminated areas.The outcoming showed that three types of crops cultivated on the high background values of the absorptive capacity of the soil of harmful elements in the order of vegetables,food fruit.The reason was that in the same area plot sampling points were different contents of heavy metals in soil samples,the same harmful elements had different accumulation characteristics for different crops and crop ty...
