Modelling and mapping of atmospheric nitrogen and sulphur deposition and critical loads for ecosystem specific assessment of threats to biodiversity in Germany – PINETI (Pollutant INput and EcosysTem Impact) Part 1

Biodiversity in Europe is strongly affected by the deposition of nitrogen and sulfur on terrestrial ecosystems. Therefore, the deposition of these atmospheric substances is assessed for the years 2008 and 2009 within the PINETI project. Dry, wet and occult deposition of NHx, NOy, SOx and the base cations Ca2+, Mg2+, K+ und Na+ are calculated and added up to the total deposition. By means of the latter and the Critical Load the Critical Load exceedances for sensitive ecosystems are assessed.
