长江口地区饮用水源地有毒有害污染状况分析与评价

通过分析与评价长江口南通地区集中式饮用水源地有毒有害污染状况,为保护区域饮用水源质量提供科学依据.对8个集中式饮用水源地的有毒有害物质的浓度进行了调查,在普查的基础上筛查出3个跟踪点,对其中挥发性有机物、半挥发性有机物、重金属、农药、多氯联苯、生物毒性、抗生素及其他项目等有毒有害物质的浓度进行了深度调查,并对各饮用水源地有毒有害污染状况作了初步评价.结果表明南通地区集中式饮用水源地有毒有害物有一定的检出,但检出值均为痕量级.建议完善饮用水水源地监控预警体系,尤其要提升饮用水源水的有毒有害物的监测能力,定期开展水源地有毒有害物的普查工作,并不断更新南通市饮用水源地中有毒有害物优先监测名录.
