摘要
通过对乌鲁木齐市“菜篮子”种植基地——安宁渠土壤中重金属、农药、多环芳烃等污染物的监测结果分析得出,该区域内的土壤中总砷、总汞、总铬、总镉等重金属和土壤中六六六、滴滴涕等含量均低于国家标准限值,土壤污染综合指数属于安全级别之内,但与历史背景值相比,部分重金属含量呈现明显的增加趋势,尤其是总铅、总砷和总镉的含量增幅较大。污染增加趋势与城市工业发展和交通污染及施用化肥、农药有关。
The pollutants such as heavy metal, pesticide and polycyclic aromatic hydrocarbon in soil of Anningqu ＂shopping basket＂ base had been monitored. The results showed that the concentration of arsenic, hydrargyrum, cadmium, DDT and 666 was under the level of national standard, and soll pollution synthetical index was in the range of safety. Compared with background value, part of heavy metals took the increase trend, especially lead, arsenic and cadmium. The trend had a relation with industry development, traffic pollution and fertilizer utilization.
