Hydrogeochemical characteristics in the arsenic poisoning area in western Jilin Province

Supported by field survey and sample test data,the SPSS is applied to analyze the relationship between arsenic concentration and chemical components.The results show that the total arsenic concentration is directly proportional to contents of Fe,HCO3-,Mn,Cl,PO43- and TDS,and inversely proportional to contents of SO42- and Se.By studying the hydrochemical conditions and integrating the quantitative relationship,the hydrogeochemical characteristics in the study area is summarized.The specific hydrogelogical characteristic in poisoning area is as follows: arsenic content in groundwater varies with different water type.It is found that the total arsenic concentration is the lowest in HCO3—Ca type water and the highest in Cl·HCO3—Na type water.
