- 摘要:
- 近年来,由于大庆市石油开采和化工业迅速发展,造成周围农田土壤重金属污染。为更好地了解这一状况,在大庆市大同区4个乡镇选取了70个样点进行采样和测试分析,利用单因子污染指数法和内梅罗综合污染指数法进行评价。结果表明:从单因子污染指数上看,4个乡镇汞因子污染相对较高,铅因子偶有超标;从综合污染指数上看,4个乡镇均存在一定的污染,其污染指数双榆树乡<太阳升镇<八井子乡<老山头乡,70个样点中61.4%属于清洁级,污染等级为安全,37.2%属于尚清洁,污染等级为警戒级,1.4%属于轻度污染。
- Abstract:
- In recent years,dued to the oil exploration and the rapid development of chemical industry in Daqing city,resulted in field soil heavy metal pollution around the farmland.For better understanding of this situation,it had select 70 samples in four villages in Datong for sampling and analyzing.And it evaluated by using single-factor of pollution index method and Nemerow integrated pollution index method.The results showed that from single factor pollution index,Hg factor pollution index relative high,Pb factor pollution was occasionally exceed the standard in four Township.From integrated pollution index,they all existed soil heavy metal pollution.Its pollution index was:Shuangyushu village < Taiyangsheng village < Bajingzi village
