摘要
对山东省黄河下游地区浅层地下水中As、Ba、Be、Ca、Cd、Co、Cu、Fe、Hg、Mo、N i、Pb、Se、Zn、F-、C l-、Cr(Ⅵ)、NO2-、COD、pH等33项指标进行分析测试;通过研究这些指标在浅层地下水中的背景含量变化规律,认为调查区内浅层地下水中As、Be、Ca、Cd、Co、Cu、Fe、Hg、Mo、N i、Pb、Se、Zn、F-、Cl-、Cr(Ⅵ)、NO2-、COD、pH等大部分指标背景值含量低于国家Ⅲ类水标准;但由于各指标分布不均匀,且富集程度相对较高,局部地段某些指标可达到Ⅳ类、Ⅴ类水标准,水质变差,不能直接饮用。统计了调查区内各地市和不同地质单元中浅层地下水各指标的背景含量,分析研究各指标在不同行政区和地质单元中的含量变化及分布规律。
According to regulations on the investigation of the shallow ground water in downstream area of the Yellow River in Shandong, the shallow ground water samples, one in every 16 km^2, were collected and 33 com-ponents including As, Ba, Be, Ca, Cd, Co, Cu, Fe, Hg, Mo, Ni, Pb, Se, Zn, F^-, CI^-, Cr（Ⅵ）, NO2^-, COD, pH and etc. were analyzed. Through the study on the changes in background values of these items, it is found that the bac Se, Zn, F^-, Cl^- kground values for most of the items such as As, Be, Ca, Cd, Co, Cu, Fe, Hg, Mo, Ni, Pb,Se,Zn,F^- ,Cl^- ,Cr（Ⅵ）, NO2^-, COD, pH, etc. are lower than the values of grade Ⅲ of the National Water Standard. But due to the uneven distribution and relatively high concentration of some elements, the quality of the ground water in certain areas may deteriorate to grade 1V or grade V of the National Water Standard, which cannot be drunk directly. The data statistics for element background values of the shallow ground water for each city and geological unit in the investigated areas are implemented and the characteristics of the distribution and changes for the components in each city and geological unit are studied.
