Abstract
About 20 years ago, long-term monitoring of small Norwegian catchments were initiated, because of increasing concern regarding acidification of surface water and damage to fish populations. Long range transported air pollutants were considered to be the major acidification factor and so both precipitation and runoff chemistry were included in the monitoring programme. This report contains a thorough hydrologic and chemical evaluation of precipitation and runoff water separately as well as relationships between precipitation chemistry and runoff chemistry. The data comes from four catchments: Birkenes, Storgama, Langtjern and Kaarvatn. The chapters are (1) Sampling and analysis, (2) Description of the catchments, (3) Hydrology, (4) Chemistry, with subsections on wet deposition, dry deposition, concentration of marine compounds with distance from the sea, acid precipitation, runoff chemistry, sulphuric acid and other acidifying compounds, acid neutralizing capacity, and aluminium, (5) Time trends in precipitation and runoff chemistry. The time trends are evaluated in relation to the declining emissions of sulphur compounds in Europe since the late seventies. 134 refs., 213 figs., 54 tabs.
