摘要
为了对容县地区地下水水质进行调查和健康风险评价,主要对常规水质指标和部分重金属(Cu、Pb、Zn和Cd)进行采样分析。结果显示:研究区pH水化学指标偏低,NO 3-超标率达到50%。通过舒卡列夫分类方法和Piper图分析方法可知研究区水化学类型较多,其中HCO 3-Ca型水占的比重最大,占比为30%。地下水中Cu、Pb、Zn和Cd的浓度对儿童和成年人健康均没有明显危害。该研究可为容县地下水资源开发利用提供参考。
In order to investigate the quality and evaluate the health risk of groundwater in Rongxian County,this study mainly samples and analyzes the conventional water quality indexes and some heavy metals(Cu,Pb,Zn and Cd).The results show that the hydrochemical index of pH in the study area is low,and 50% of samples exceed the concentration limit of NO-3.After application of the Schukalev classification method and Piper diagram analysis method,it can be concluded that there are many hydrochemical types in the study area,among which HCO 3-Ca type water accounts for the largest proportion for 30%,and the low concentration of Cu,Pb,Zn and Cd has no obvious impact on the health of children and adults.This study could provide reference for the development and utilization of groundwater resources in Rongxian County.
