摘    要:由于土壤中重金属元素的含量对人体健康影响很大,淮阴市环境监测中心站于1993年至1997年造反某污灌区中0.667hm^2的蔬菜田及其邻近的某一地下水灌区中0.667hm^2的蔬菜田按梅花布点法分别布设8个测点,对其土壤中的总镉、总汞、总砷、总铬和总锅进行监测。结果表明,地下水藻区5年来综合污染指数变化不大,污染等级属安全级,说明该灌区没有受到重金属污染,而污灌区的综合污染指数逐年增高,1995年

关 键 词:重金属  土壤污染  污灌区  地下水灌区

Abstract:Cadmium, mercury, arsenic, chromium and lead were monitored by Huaiying Municipal Environmental Monitoring Station from 1993 to 1997 in a vegetable field of 0667 hm2 in polluted irrigation and in a vegetable field of 0667 hm2 in ground water irrigation with 8 related monitoring spots. The monitoring results showed that in those 5 years in field of ground water irrigation the comprehensive pollution index did not change much, the pollution was in safety category; while in field of polluted irrigation the comprehensive pollution index increased year by year, with its reaching warning category, which indicated that corresponding heavy metals were accumulated and crops were polluted. The article points out that longterm polluted irrigation deposited heavy metals in soil, which polluted the soil and need to be countermeasured.
Keywords:Heavy  metals  Soil  pollution  Polluted  irrigation  Ground  water  irrigation
