Review and revision of empirical critical loads and dose-response relationships : Proceedings of an expert workshop, Noordwijkerhout, 23-25 June 2010(Rijksinstituut voor Volksgezondheid en Milieu RIVMB-WARE (KUN), 2011-05-19)This report describes the scientific background and results from the review and revision of empirical critical loads of nitrogen that had been established for Europe in 2003 under the auspices of the UNECE Convention on Longrange Transboundary Air Pollution (LRTAP Convention). In 2009 the Coordination Centre for Effects started a project under the LRTAP Convention to bring empirical critical loads up to date. New relevant information from studies (autumn 2002 - spring 2010) on the impacts of nitrogen on natural and semi-natural ecosystems was incorporated in the existing European database on empirical critical loads of N. Empirical critical loads were structured following the classification used in the European Nature Information System (EUNIS). Consensus on the results was obtained in a UNECE workshop on the 'Review and revision of empirical critical loads and dose-response relationships' (23-25 June 2010, Noordwijkerhout, the Netherlands), organised by the Coordination Centre for Effects and the B-WARE Research Centre. The results, as provided in Table 1 of the Executive Summary, show that in many cases the outer ranges of the empirical critical loads have decreased. The resulting European database of 2011 includes both revised and newly established value ranges of empirical critical loads of nitrogen for each EUNIS class. The outcome of this report is of major importance for the protection of N-sensitive natural and semi-natural ecosystems across Europe. This knowledge is used in support of European policies to abate air pollution.
