为了解长株潭地区集中式饮用水水源地周边土壤环境质量情况,以长株潭地区6处具有代表性的集中式饮用水水源地周边土壤为监测对象,对采集土壤样品中的pH值、阳离子交换量、有机质含量及典型污染物进行了测定与分析。结果表明:长株潭地区6个集中式饮用水水源地周边土壤中pH值、阳离子交换量及有机质含量存在差异;30个监测点位土壤中Cd,Pb,Zn,As和Ni平均含量超标率分别为63.33%,63.33%,73.33%,33.33%,13.33%,Hg,Cr,Cu平均含量超标率均为16.67%,六氯环己烷、滴滴涕及苯并[a]芘含量均未超标;单因子评价和综合评价得出,水源地周边土壤主要以无机污染为主,只有3个监测点位存在有机污染,所有监测点位的土...

In order to understand the environmental quality of the surrounding drinking water source in Changsha—Zhuzhou—Xiangtan area,The pH value,cation exchange capacity,organic matter content and typical pollutants in the collected soil samples from the surrounding soil of the centralized drinking water source area in Changsha—Zhuzhou—Xiangtan area were measured and analyzed. The results showed that there were differences in pH value,cation exchange capacities and organic matter contents in the surrounding soil of six centralized drinking water so...
