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.
