A multiple-year emission inventory of hazardous air pollutants (HAPs) including particulate matters (PM), SO2, NOX, CO, HCl, As, Cd, Cr, Hg, Ni, Pb, Sb, and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs), discharged from municipal solid waste (MSW) incineration in China has been established for the period 2003-2010 by using best available emission factors and annual activity data. Our results show that the total emissions of NOX, SO2, CO, PM, HCl, Sb, Hg, Pb, Cr, Ni, Cd, As, and PCDD/Fs have rapidly amounted to 28471.1 metric tons (t), 12062.1 t, 6500.5 t, 4654.6 t, 3609.1 t, 69.5 t, 36.7 t, 9.4 t, 4.4 t, 2.8 t, 926.7 kg, 231.7 kg, and 23.6 g TEQ (Toxic Equivalent Quantity) by the year of 2010, respectively. The majority of HAPs emissions are concentrated in the eastern central and southeastern areas of China where most of MSW incineration plants are built and put into operation. Between 2003 and 2010, provinces always rank at the top three with largest HAPs emissions are: Zhejiang, Guangdong, and Jiangsu. To better understand the emissions of these HAPs and to adopt effective measures to prevent poisoning risks, more specific field-test data collection are necessary.
