| 摘 要： | 对天津市西青区某国家级蔬菜基地的土壤进行采样,用原子吸收光谱法和石墨炉法分析土壤中Cd、Cr、Cu、Pb、Zn、Hg、Se七种元素的含量。根据GB15618-1995土壤环境质量标准对检测结果进行了单因子和多因子综合污染指数评价。分析显示,调查区内除个别地块重金属元素Cd的含量达到轻度污染外,其它重金属元素的含量在安全警戒线内。调查结果表明,该区域内的土壤可以作为蔬菜基地使用。

| Abstract: | The soil was sampled in a vegetable planting base near suburbs of Tianjin City. The levels of Cd, Cr, Cu, Pb, Zn, Hg and Se in soil sample were determined by atomic adsorption spectral photometry. Based on soil environment quality standard, the classification and assessment of single factor and multifactor were done. Results showed that other heavy metals contents were in safe level except Cd, which indicated that the soil in this region is suitable for vegetable planting. |
