济南市典型地段地下水氨氮污染分析评价

Analysis and assessment of ammonia nitrogen compound in groundwater of Jinan typical areas

通过对济南市4个监测点2005至2007年间地下水中的氨氮浓度的分析研究,探讨了氨氮污染物对地下水水质的影响,以及氨氮污染物的来源,并针对这4个监测点地下水中的氨氮污染物进行了健康影响评价。结果表明:(1)4个监测点地下水中都有氨氮出现,而且在这3年期间,地下水中的氨氮浓度增长很快,其中3个监测点的地下水质量,由于氨氮的影响,从2005到2006年由Ⅰ类降为Ⅲ类;(2)4个监测点地下水中的氨氮都来自人为污染,而且污染源没有得到有效控制;(3)健康风险评价结果显示,4个监测点地下水中的氨氮都还不会对人体健康造成危害。

Through the analysis of the concentration of ammonia nitrogen in groundwater of Jinan,the study explores the health risk assessment for ammonia nitrogen compound.Results show：（1） the ammonia nitrogen compound levels in 4 groundwater monitoring sites of Jinan increased rapidly between 2005 and 2007 and the quality of groundwater has been made declining;（2）the ammonia nitrogen compound in groundwater of Jinan comes from artificial pollution sources and the pollutions are continuing;（3）ammonia nitrogen compound in groundwater of Jinan has no serious detrimental effects on human health according to the hazard quotients.
