註釋This report provides a preliminary assessment of critical loads of Cu, Ni, Zn, Cr, As and Se for Europe. Critical loads were computed according to existing methods, for forest soils and agricultural soils. Critical loads were assessed aiming at groundwater protection and for avoiding ecotoxicological effects on soil organisms. Methods and input data for the models are described as well as critical limits used. Maps are provided showing the geographical distribution of 5 percentile critical loads for Europe for each metal and effect separately. Results of the study are discussed in terms of geographical patterns and critical load ranges, and some indication of uncertainties and possible improvements of the applied methods and data is provided.
