Mercury emissions in Europe – electricity and heating欧洲汞排放-电力和供暖(EU-27, 1990-2008, from EEA, 2010) (欧盟27国,1990-2008年,欧盟环保署2010年数据)
Mercury emissions in Europe – metals production欧洲汞排放-金属生产(EU-27, 1990-2008, from EEA, 2010) (欧盟27国,1990-2008年,欧盟环保署2010年数据)
Mercury emissions in Europe – chemical industry, incl. chlor-alkali欧洲汞排放-化工,包括氯碱(EU-27, 1990-2008, from EEA, 2010) (欧盟27国,1990-2008年,欧盟环保署2010年数据)
Drivers for reductions in Europe • Technologies • Policies and legislation • Public awareness
Drivers for reductions in Europe Coal fired power plants and boilers: • Close down old power plants and boilers • Increasingly advanced SO2, PM and NOX control • Increasing energy efficiency • No specific mercury reducing technology! • All co-benefits of other measures Mercury emissions in Europe – electricity and heating欧洲汞排放-电力和供暖(EU-27, 1990-2008, from EEA, 2010) (欧盟27国,1990-2008年,欧盟环保署2010年数据)
Drivers for reductions in Europe Metals smelting: • Largest reduction before 1990! • Development of technologies for mercury control since 1970s, eg in Zn industry: • Norzink-Boliden process • Outokumpu/Outotec process • Increasing environmental awareness • Specific mercury reducing technology! • Very efficient reductions • Cost effective!

European strategy on mercury pollution欧洲汞污染防治策略 • Reduce emissions减排 • Reduce use (supply and demand)减少使用(供、需) • Resolve long-term fate of mercury解决汞的远期去向问题(in products still in use or in storage) (仍在使用或被储存的含汞产品) • Protect against exposure避免暴露 • Improve understanding提高认识 • Support international action支持国际行动

Conclusions结论 • Mercury emission control has been quite successful in Europe • 欧洲的汞排放控制非常成功 • China is now a key to reduce global mercury emissions • 减少全球汞排放,中国至关重要 • Mercury concentrations in the environment is not yet decreasing • 环境汞污染浓度并未下降 • Use of best available technology is important to reduce emissions • 着重利用“最佳可用技术”减少汞排放 • Possible in Europe, possible in China • 中国不妨借鉴欧洲的经验
