The atmosphere remains the major source of mercury in Swedish ecosystems. Since the late eighties, atmospheric emissions of mercury have drastically decreased in Europe. Wet deposition of mercury has decreased over the last decade but still exhibits a clear south-to-north gradient, greatly influenced by source areas in northern and central Europe. The decreases in emissions can be attributed to both direct measures to close known point sources and a declining economy and energy consumption in many East European countries. Further reductions of mercury emissions will require that other source categories such as indirect emissions from mercury-containing products and crematories are be considered.
