Tendencies of Change in the Chemistry of Precipitation at Three Monitoring Stations 1996-1999

Abstract

This study compares the results of three stations differing greatly in geography, and tendencies of change in the chemistry of precipitation (open and throughfall) in the years 1996-1999. The mean annual pH is lower than 5.2, and often drops below 4.6. A distinct decline in the concentrations of sulphate ions at all the stations is observed.
