徐州市北郊工业区浅层地下水重金属污染研究
Pollution Assessment of Heavy Metals in Shallow Groundwater
徐州市是我国重工业城市之一，目前徐州市大部分工业、企业分布在北郊。由于各种原因，十几年来北郊工业区重金属污染物的排放量并未减少，通过污水灌溉、地表径流下渗等途径扩散迁移到浅层地下水中的重金属可能已经危及到地下水的安全。为此，本研究以该区为研究对象，根据该区地下水的流向进行了系统采样，对采集到的地下水样品中的重金属元素进行了系统分析，以饮用水标准为评价标准，采用单因子法进行了评价。结果表明，Cu、Zn、Hg三种元素均未造成污染；Ni元素有三个采样点超标；61%上的样品中Cd元素达到或超过饮用水水质标准上限；Mn的浓度69％样品超标；Pb元素污染严重且已影响到整个研究区。
his article deals with the impacts of past industry activities and inefficient water resources management on shallow groundwater quality in the Northern Suburb of Xuzhou City. Thirteen water samples were collected during September 2005 and were analyzed for major heavy metals ions (Pb, Ni, Zn, Mn, Cu, Cr, Cd, Hg). High concentrations of heavy metals (Pb、Mn) are recorded in groundwater samples in the area. The highest came from the No.12 and 4 sampling point respectively. The concentration of cadmium exceeded the upper limit for drinking waters for 61% of the samples but Cu、Zn、Hg not.
