邯郸市郊区菜园土壤重金属污染状况的调查与评价

对邯郸市郊区环城路附近菜园土壤进行了采样 ,用原子吸收光谱法分析土壤中Cu、Pb、Zn三种元素的含量。根据GB1 5 61 8- 1 995土壤环境质量标准对检测结果进行了单因子和多因子分级与评价。调查区内 ,重金属元素Cu、Pb、Zn的污染较普遍 ,且多为 2种以上元素的复合污染。Zn元素污染较显著 ,达中度污染 ,Cu、Pb为非污染至轻度污染。调查区域土壤的综合污染指数为 1 .3,达 3级为轻度污染

Study on pollution of heavy metal in vegetable-planting soils in the suburbs of Handan city

The sampling of soil was done in the vegetable planting soils near the suburbs of Handan city. The levels of Cu, Pb and Zn in soil sample were determined by atomic adsorption spectrophotometry. According to the soil environment quality standard (GB15618-1995), the classification and the assessment of the single factor and multi factor were done to the detect result. The result showed that the soil pollution from the heavy metals (Cu, Pb and Zn) was quite obvious, and most of them was polluted. The soil samples were highly polluted by Zn, which was moderate polluted, and slightly polluted by Cu and Pb, which was non polluted or slight polluted. And the synthetic index of soil pollution was 1.3, which was three grade slight pollution.
