14 Country-scale pollution assessment Case studies of HM pollution in selected EMEP countries Approach: Evaluation of pollution levels in a country with fine spatial resolution involving variety of national data Requirements: Detailed emissions data (fine resolution, source categories, LPS) Additional measurements from national monitoring networks Participation of national experts in joint analysis of the results Countries involved: CountryCzech RepCroatiaNetherlandsBelarus Statuscomplete in progress Croatia Netherlands Czech Republic Workshop on CLRTAP Assessment report, 2015

18 Climate change has the potential to affect all POPs pathways in the atmosphere, hydrosphere, cryosphere, biosphere, and soil. There is evidence that climate change phenomena, e.g., elevated temperatures and sea-ice reduction, and extreme climate events, such as forest fires, flooding and glacial melting, will remobilize POPs previously deposited in sinks, e.g., forest soils and vegetation, ocean and lake sediments and glaciers.
