摘要
通过对乌鲁木齐市郊区部分蔬菜基地土壤中重金属的调查和采样分析,依据国家土壤环境质量二级标准评价其单项和综合污染指数,结果表明,其单项污染指数小于1.0,综合污染指数均低于0.7,评价结果均为安全指标范围内,土壤质量基本上对蔬菜和环境不造成污染和危害。
The soil samples collected frown the vegetable bases in suburb of Urumqi were investigated and the heavy metal contents in soils were analyzed. Evaluation of indexes of single contaminants and combined pollution was made according to the national standard for evaluation of soil environmental quality. The results showed the indexes of monomial and synthetic pollution were less than 1 and 0,7, respectively. The evaluation indicated that soil environmental quality is in a safe degree.
