摘要

An inventory of anthropogenic primary aerosol emissions in China wasdeveloped for 1990–2005 using a technology-based approach. Taking intoaccount changes in the technology penetration within industry sectors andimprovements in emission controls driven by stricter emission standards, adynamic methodology was derived and implemented to estimate inter-annualemission factors. Emission factors of PM2.5 decreased by 7%–69%from 1990 to 2005 in different industry sectors of China, and emissionfactors of TSP decreased by 18%–80% as well, with the measures ofcontrolling PM emissions implemented. As a result, emissions of PM2.5and TSP in 2005 were 11.0 Tg and 29.7 Tg, respectively, less than what theywould have been without the adoption of these measures. Emissions ofPM2.5, PM10 and TSP presented similar trends: they increased inthe first six years of 1990s and decreased until 2000, then increased againin the following years. Emissions of TSP peaked (35.5 Tg) in 1996, while thepeak of PM10 (18.8 Tg) and PM2.5 (12.7 Tg) emissions occurred in2005. Although various emission trends were identified across sectors, thecement industry and biofuel combustion in the residential sector wereconsistently the largest sources of PM2.5 emissions, accounting for53%–62% of emissions over the study period. The non-metallic mineralproduct industry, including the cement, lime and brick industries, accountedfor 54%–63% of national TSP emissions. There were no significanttrends of BC and OC emissions until 2000, but the increase after 2000brought the peaks of BC (1.51 Tg) and OC (3.19 Tg) emissions in 2005.Although significant improvements in the estimation of primary aerosols arepresented here, there still exist large uncertainties. More accurate anddetailed activity information and emission factors based on local tests areessential to further improve emission estimates, this especially being sofor the brick and coke industries, as well as for coal-burning stoves andbiofuel usage in the residential sector.
