【摘要】 以上海化学工业区地下水水质监测资料为基础 ,结合实际情况选取 2 2项评价因子 ,依据地下水质量标准 ,采用综合评价法对该地区的地下水环境质量进行评价分析。评价结果表明 ,化工区地下水环境质量状况较差 ,监测项目中无机物超标情况严重 ,某些金属离子和酸根离子含量较高 ;而有机物指标含量均低于方法检出限。此外 ,该地区地下水水化学特征呈明显的水平分带性 ,由南至北宏量元素逐渐降低 ,酚类含量逐渐增高 ,而重金属含量则基本保持不变 ,水化学类型由咸水类型向淡水类型转变更多还原

【Abstract】 The paper is aimed to present the authors’ investigation of the groundwater situation of Shanghai Chemical Industrial Zone by taking 22 factors for samples to be evaluated, which was done in accordance with the groundwater quality standard given by the Mark Assessment. The results of our investigation are focused on the following points: the groundwater quality is comparatively lower in most areas. Some monitoring items, such as metal ions and acid radicals, yield to severe super-standard, to which it is necessary to pay more attention to. Nevertheless, the content of the organic substances have been found lower than the standard limit. In addition, the hydrochemical characteristics of the groundwater appear to be remarkable in horizontally zoning form, with its macro elements gradually decrease from the north to the south while the content of phenols being enhanced. Although the metal content in the groundwater is basically invariable, the hydrochemical types are changing from salt-water into fresh-water.更多还原
