Abstract
Atmospheric deposition of nitrogen compounds over the countryside has had a significant influence on plant production in such a way that the addition of nitrogen in woods, heaths and high-lying bogs is the main source of nitrogen supply to the plant communities. The atmospheric conveyance of this nitrogen to Danish inner channels is the main concern of the study. Deposition in the form of rain and of gases and particles is measured from 17 measurement stations. This constitutes between one quarter and one third of the total amount of added nitrogen to Danish inner waters. The results of these measurements are presented. It is concluded from these continuous measurements over the past three years that the atmospheric content of nitrogen dioxide, ammonia and nitrate is partly the result of long-distance transport, mainly by southerly and westerly winds, though ammonia also originates from local Danish sources, especially from farming areas. Sulfur dioxide and sulfates appear to be blown over from sources in Eastern Europe. Sulfur compounds are of special significance with regard to soil acidification. Heavy metals have contributed to the general contamination of land and marine areas. (AB) (23 refs.).
