Deposition of major inorganic compounds in Norway 1978-1982 and 1997-2001: status and trends.

The total deposition of sulphur and nitrogen compounds in Norway during the period 1978-1982 and 1997-2001 has been estimated on the basis of available measurement data for concentrations and precipitation. Deposition of non-marine base cations is also estimated. Results are compared with previous estimates for 1988-92 and 1992-96.
