| 摘 要： | 目的]评价山东省蔬菜基地灌溉水重金属环境质量。方法]对山东省主要蔬菜产地的灌溉水进行了重金属Hg、Cd、As、六价Cr、Pb、Cu和Zn含量的抽样调查分析,并采用单项质量指数与综合质量指数相结合的方法对重金属的环境质量状况进行了评价。结果]寿光、莱阳、金乡和章丘4个蔬菜产地灌溉水中各重金属的平均含量均远低于《食用农产品产地环境质量评价标准》（HJ332-2006）规定的限值,未发现重金属含量超标现象;4地灌溉水重金属的单项质量指数均小于0.5,综合质量指数分别为0.3178、0.3204、0.2326和0.2607,灌溉水环境质量均为1级。结论]4个蔬菜产地的灌溉水环境质量属于清洁水平,适宜作为无公害蔬菜的灌溉用水。

| Abstract: | Objective]The aim was to evaluate heavy metal environmental quality of irrigation water in vegetable farmlands of Shandong province.Method]Heavy metal contents including Hg、Cd、As、Cr(+6)、Pb、Cu and Zn in irrigation water of main vegetable farmlands of Shandong province were investigated by randomly sampling,and the environmental quality conditions of these heavy metals were evaluated by methods of single quality index and complex quality index.Result]The results showed that the average contents of heavy metals in irrigation water of Shouguang,Laiyang,Jinxiang and Zhangqiu were all far lower than the limit values prescribed by "Farmland environmental quality evaluation standards for edible agricultural products" (HJ332-2006),and no heavy metal was found beyond the limit value in every sample. The single quality indices of the seven elements in the studied four places were all lower than 0.5,the comprehensive quality index of the seven elements was 0.317 8 in Shouguang,0.320 4 in Laiyang,0.232 6 in Jinxiang,and 0.260 7 in Zhangqiu. The environmental quality of irrigation water in the studied four places were all set at the first class.Conclusion]The environmental quality of irrigatiom water in the four places belong to clean level and were fit for the plantation of no pollution vegetables. |
