A Comparison of the Acidity of Rain and Snow with Chemical Components in Winter

The data of the rain and snow acidity and the chemical components in winter from 1985 to 1991 are analysed.The results show that the frequence of acid snow is different every year,but.it is loWer than that of the acid f rain iii the same season.The snow acidity is less than that of the rain.The negative relationship between the snow acidity and the cond.uctivity is very clear.The analysis of the chemical components of snow suggest f that the SO^2-₄ content is becoming more and more the Cl^- level tends to disctease,the NH⁺₄ is of in4inly positive irans.
