摘　　要：目的 :探讨鲁西南地区地面水水质化学指标和微量元素含量 ,为防治污染和水资源开发利用提供科学依据。方法 :采集微山湖、东平湖和尼山水库水样 ,按GB5 75 0 - 85《生活饮用水标准检验法》和GB/T85 38- 1995《饮用天然矿泉水检验方法》进行水质分析。金属元素测定用石墨炉原子吸收光谱法。结果 :鲁西南地区地面水中氯化物、硫酸盐、总硬度、溶解性总固体含量较高 ,水质盐化问题突出。尼山水库水质明显优于东平湖和微山湖 ;离城市近的地面水体污染重 ,化合物和微量元素含量多 ,部分指标含量明显高于地下水。结论 :鲁西南地区地面水中化学指标和微量元素含量升高可能与地质环境和人为环境污染有关。Objective:To explore the chemical index and trace metal levels of surface water in south-western Shandong province and to provide basic scientif ic data for preventing pollution and developing water resource. Methods:The water samples collected from the surface water in Weishan Lake ,DongPing Lake and NiShan Reservoir(n=24) were analyzed according to GB5750-85 Standard Examination Methods for Drinking Water and GB/ T8538 -1995 Methods for Examination of Drinking Natural Mineral Water.The c ontents of metall ic elements were determined by graphite furnance-atomic absorption spec trophoto metry.Results:The contents of chloride,sulfate,total hardness and total deliquescent solid in surface water was high in South-western Shandong Province.The salinization of water was a problem clearly.The water quality in Nishan Reservoir was better than that in Dongping Lake or Weis han Lake.The surface water in areas near cities was polluted obviously.Ther e were more chemical composition and trace elements in water. Many of them were higher in surface water than in underground water.Conclusion:The increase of contents of chemical composition and tr ace elements in surface water of Sourh-western Shandong Province were probably caused by geological environment and anthropogenic environment pollution.
