【摘要】 通过研究浅层地下水中29项元素或指标的地球化学特征,认为研究区浅层地下水中Mo、Pb、Mn、Fe、Cl^-、NO₂^-、总硬度等含量变化较大,局部水质变差,其他指标含量变化较小,在浅层地下水中分布均匀。该区不可直接饮用的浅层地下水占44.88%,综合环境质量较差;地下水污染多发生在主要城市、工矿企业及其周边地区,单指标水污染呈点（源）状、线状分布,主要超标项目为总硬度、溶解性总固体、高锰酸钾指数、NO₂^-、Cl^-、F^-、Mn、Fe等8项指标。更多还原

【Abstract】 In this paper,the geochemical characteristics of the 29 elements & indicators had been analyzed,the results show that several indicators of the shallow groundwater in study area changed more,such as Mo,Pb,Mn,Fe,Cl -,NO2 -and total hardness,other indicators changed less,and evenly distributed in the shallow groundwater., Based on the shallow groundwater data which belong to the agro-ecological geochemical survey in regions of eastern Shandong Province,which leaded to deterioration of local groundwater quality.The evaluation of the single factor and integrated environmental quality were executed,,according to the Quality standard for groundwater and Standards for Drinking Water Quality,the results show that the area of shallow groundwater can not be directly for drinking accounted for 44.88%,and integrated environmental quality is poor.Groundwater pollution mainly occurred in major cities,industrial and mining enterprises resident and the surrounding area.Single indicator groundwater pollution was one point source like or linear distribution,and the indicators,which included total hardness,total dissolved solids,potassium permanganate index,NO2-,Cl-,F-,Mn,Fe etc.,exceeded the permission.更多还原
