Description: Das Projekt "Quecksilberarten in Europa (MOE)" wird vom Umweltbundesamt gefördert und von GKSS-Forschungszentrum Geesthacht, Institut für Gewässerphysik durchgeführt. The general objective of the MOE project is to identify and quantify sources of atmospheric mercury (Hg) species focusing on production and fluxes of methylmercury (MeHg). The primary objective is to find the relative importance of the atmospheric deposition of MeHg, in comparison to methylation/demethylation processes in terrestrial and limnic ecosystems, in the heavily impacted regions in nothern and central Europe. MOE will provide important missing pieces on the occurrence of direct and diffuse emissions, and of atmospheric production, of the Hg species contributing to the MeHg found enriched at different trophic levels in our ecosystems. From this, MOE will asses the capability of MeHg of atmospheric origin to act as a net source for MeHg transport over transition zones between terrestrial, wetland, and limnic ecosystems. The information will be necessary in constructing adequate multicompartment models for the fate and effects of eco-toxicologically relevant Hg species, eg MeHg, and assessing impacts from environmental changes.
