上海地区浅层地下水有机污染基本特征

The Contamination of Phreatic Water in Shanghai by Organic Compounds

上海地区浅层地下水中含有不同种类的有机物,大多数检出浓度相对较低,并呈散点状空间分布特征。局部地段存在有机物聚集与含量偏高,与以往的工业污染源关系密切。环境治理成效的显现将使地下水中有机物的检出与含量进一步降低。

Several classes of organic compounds have been detected in the phreatic waters of the Shanghai area.Most are found in very low concentrations,but are widely distributed.However,locally high concentrations of these organic compounds do occur,particularly close to contaminated former industrial sites.Improved treatment of such contaminated sites will further reduce the rate of leaching of organic compounds into the environment,and so reduce their concentration in phreatic water.
