为了解长沙市边缘带菜园土壤重金属污染状况,建立无公害蔬菜生产基地,指导蔬菜生产,通过田间采样方法,对长沙市郊陈家渡、东湖村、潭阳洲、杉木村和(朗木)梨村5个主要蔬菜基地0～20 cm表土共计290个样本中7种重金属元素的含量进行了分析.结果表明,Cu、Cd、Pb、Zn、Cr、As、Hg全量分别为10.70～122.20、0.10～3.70、23.50～95.90、81.00～309.80、9.90～145.60、6.70～39.90、0.02～1.50 mg/kg;含量的变异系数分别为8.2%～29.4%、31.2%～182.4%、8.1%～21.6%、10.5%～33.2%、11.3%～29.8%、5.7%～28.1%、20.8%～37.9%.Hg、Cu、Cd为主要重金属污染元素.5个蔬菜基地中,陈家渡达中度污染水平,其他4个...

By field investigation and sampling and laboratory analysis, contents and current pollution situation of the heavy metal elements were investigated at peri-Urban Changsha. 290 soil samples were obtained from 0-20 cm topsoil from 5 sampling areas, such as northern suburbs of Chenjiadu, the eastern suburbs ofDonghu, Tanyang, Shamu and the southern suburbs of Langli. The levels of 7 heavy metals in soil sample were determined by atomic adsorption spectrometry and atomic fluorescence spectrometry analysis. The results showed that the average content of Cu, Cd, Pb, Zn, Cr, As andHgwere 10.70-122.20...
