Acid–Base Characteristics of Russian Snow Cover

V. N. Vasilenko, I. E. Artemov, T. V. Belikova, and A. A. Uspin

The results of pH measurement results are summarized for 1994–2004. These were obtained from the snow pollution and acidity monitoring network in the Russian Federation. A map of acid–base characteristics is compiled for the Russian territory. The zones of the most frequent cases of snow acidification are singled out. Dependence of pH values on the concentration of acid-forming anions neutralizing cation acids is established based on the ion balance analysis.
