Veröffentlichung Critical Loads of Cadmium, Lead and Mercury and Their Exceedances in Europe(2015)In this chapter information is summarized on the assessment of the risk of impacts of cadmium, lead and mercury emissions and related depositions of these metals, with an emphasis on natural areas in Europe. Depositions are compared to critical loads to identify areas in Europe where critical loads are exceeded. Critical loads of cadmium, lead and mercury were based on (i) computations by 18 Parties to the Convention on Long-range Transboundary Air Pollution (LRTAP) and (ii) computations from available data on soil chemistry, meteorology and land cover for the other Parties. Two target years are considered, i.e. 2010 and 2020. Emissions for these years have been assessed in support of the negotiations for the review and possible revision of the Heavy metal protocol (Aarhus 1998). The relationship between emissions, depositions and critical load exceedances is analysed assuming the implementation of abatement techniques under Current LEgislation in 2010 (CLE2010) and in 2020 under Full Implementation of the Aarhus protocol (FI2020). Comparing the critical loads to atmospheric depositions in these years, shows that cadmium deposition is not a widespread risk in either years, that the computed risk of lead deposition affects about 22 and 16?% of natural European area in 2010 and 2020, respectively, and that mercury deposition is computed to affect an area of more than 74?% in both years.Quelle: http://link.springer.comVeröffentlichung Modelling approach for a PCB inventory in our environment(2016) Knetsch, GerlindeThe data of more than 100 monitoring programs in Germany for the substance group of persistent organic pollutants (POPs), including the polychlorinated biphenyls (PCBs) are to be used for a modelling approach for a PCB inventory.The application landscape of the Federation/Laender POP-Dioxin-Database, which is operated in the German Environment Agency, pursues an interdisciplinary approach and includes all these data. A cross-media evaluation and assessment of environmental data are necessary and relevant to the target system, compiling an inventory of PCBs in our environment. The question arises how the integrated modelling concept can control the knowledge-based methods, with the aim to assess the state of PCB contamination in context to PCB-footprints in the environment.
