摘要

China has set an ambitious target of increasing energy efficiency by 20% and reducing pollution discharges by 10% over the period 2006-2010. Promoting advanced technologies and closing outdated facilities are widely recognized as important measures to achieve these targets. These actions can also indirectly decrease release of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). The objectives of this paper are to identify and quantify reductions of PCDD/F emissions to air due to measures such as phasing out of obsolete facilities in the four most energy-intensive industrial sectors. Reductions in PCDD/F emissions from power generation were estimated to be 7,33 and 38 g I-TEQ in 2006, 2007 and 2008, respectively. For the cement industry, reductions were estimated to be 680 g I-TEQ between 2007 and 2008, and 740 g I-TEQ between 2009 and 2010. For the iron and steel industry, the reduction was estimated to be 113.3 g I-TEQ over the period 2007-2010, which includes 76.6 g I-TEQ in 2007. For the coke industry, the reduction was estimated to be 68 g I-TEQ in 2007 and 62 g I-TEQ in 2008. (C) 2009 Elsevier Ltd. All rights reserved.
