天津市浅层地下水Pb污染研究

Research on Lead Pollution of Shallow Groundwater in Tianjin City

介绍了 Pb在自然条件和人为条件下的行为特征 ;以天津地区为例 ,对浅层地下水中的 Pb与其他化学组份进行了相关分析和聚类分析 .结果表明 ,天津市浅层地下水 Pb含量为 0 .0 1 2～0 .360 mg/L,并呈正偏态分布 ,其峰型比正态分布更尖锐 ;Pb与矿化度 ,Fe,NH4+ 的线性关系密切 ,与 Fe。

Behaviour of Pb in both natural and artificial conditions was introduced. The shallow ground water of Tianjing area was taken as an example to make the correlative analysis as well as cluster analysis of Pb with other chemical compositions. The result shows that the content of Pb is 0.012~0.360 mg/L, and is in a normal skew distribution, with its peak form being sharper than that of normal distribution. The Pb is closely related to the mineralization, Fe, and NH + 4; And the similarity of Pb to Fe and Mn is good.
