Trends in Nitrogen loads and concentrations, Baltic Sea, 1900-2030
Year:
2006
Author:
Philippe Rekacewicz, UNEP/GRID-Arendal
Description:
The graphic show trends in Nitrogen loads and concentrations in the Baltic Sea from 1900 to 1995 with projections to 2030. The main source of nitrogen in soils is from organic matter. Nitrogen also comes from sources such as factories. A common concern with these forms of inorganic nitrogen is the incremental amount of nitrates they add to the nitrogen cycle, which may threaten groundwater, inland waters and fisheries.
