【摘要】对济南东北郊菜地土壤及两种常见蔬菜(萝卜、白菜)中的重金属(镉、铅、汞)含量进行调查与分析.结果表明:菜地土壤中重金属单项污染指数为汞＞镉＞铅,值均小于1,超标率均为8.3%,综合污染指数为0.560,土壤属安全;蔬菜中重金属含量均未超标;蔬菜对镉的吸收能力远大于铅,且白菜对重金属的吸收能力较萝卜强.%In this paper, the contents of heavy metals (Cd, Pb and Hg) in soil and two common vegetables ( turnip and Chinese cabbage) in the main vegetable production areas of northeast suburbs of Jinan were examined and analyzed. The results showed that the single pollution index of heavy metal was in the order of Hg ＞Cd ＞ Pb and all were less than 1 with the over sanitary standard rate as 8.3％. The comprehensive pollution index was 0. 560, so the soil was safe. The contents of Cd, Pb and Hg in vegetables were below the sanitary standard for pollution -free vegetables. The absorption ability of Cd in vegetables was much higher than that of Pb and the heavy metal concentrations in Chinese cabbage were higher than those in turnip. 【总页数】3页(68-70)
