| Short description: |
Long-term records of nitrogen deposition and concentrations in streamwater were analysed at 30 sites covering the major regions in Europe that are sensitive to acidification.
|
| Long description: |
Much of Europe has received high inputs of inorganic nitrogen during the past 20-30 years, with the exceoion of a decline of approximately 20% in central and northern Europe during the late 1990s. Nitrate concentrations in stream waters are related to the amount of N deposition. Sites where deposition is less than 10 kgN ha-1 yr-1 have low concentrations of nitrate in streamwater, whereas all sites receiving > 25 kgN ha-1 yr-1 have elevated concentrations. For the level of N deposition typical for Europe nitrogen saturation is a process that takes many decades, although declining nitrate concentrations at a few sites may reflect recent reductions in N deposition. Short and long-term variations in climate affect nitrate concentrations in streamwater, obscuring long-term trends. Empirical data for geographic pattern and long-term trends in the response of surface waters to changes in N deposition are used to predict future contributions of nitrate to acidification of soils and surface waters.
