To detect changes in concentrations of chemical parameters in surface waters (rivers and lakes) related to changes in anthropogenic deposition input from longrange transboundary air pollution, in particular sulpur and nitrogen. The results are used as a basis to understand the biological responses to changes in acid deposition input.
The monitoring programme includes measurements of: - Cations: Ca, Mg, Na, K, NH4, Al (rective Al, Inaorganic and organic bound) - Anions: Cl, SO4, NO3, PO4 - Other: Organic Carbon (TOC), Total N
