After one year of monitoring and analysis of the atmospheric precipitation in Weinan, the precipitation amount, pH value, and the change characteristics of conductivity of the atmospheric precipitation were obtained. The concentrations of five kinds of cation （Ca^2＋,NH^4＋,Mg^2＋,Na^＋,K^＋） and four kinds of anion （F^-,Cl^-,SO4^2-,NO3） in the precipita- tion of Weinan and Nanjiao Village were determined by ion chromatography. The results showed that the concentration of SO3 and NO3 in atmospheric precipitation of Weinan changed significantly, while there was no significant change observed on the concentration of F^-, Cl^-, Mg^2＋, K^＋ and Na^＋ in a year.展开更多
