摘要
测定了95份土壤样品、94份水样以及292份蔬菜样品中汞的含量,探讨了广州市蔬菜地土壤-蔬菜中重金属Hg污染状况。发现蔬菜中的Hg含量与土壤中的Hg含量较为密切。广州市土壤、蔬菜中Hg的含量水平均比过去大幅度降低。蔬菜中Hg含量与其它城市比较,污染情况较轻,处于其它城市的中低水平。
The levels of mercury in 95 soil samples, 94 water samples and 292 vegetable samples obtained from vegetable farm insuburb of Guangzhou were detected. The paper also discussed the pollution of mercury in vegetable farm soi1s and vegetables.Wefind that the content of Hg in vegetables is correlation to that one in soils.
