Emission Inventory and Speciation of PM in the Yangtze River Delta region, China

摘要

In this paper, a high-resolution emission inventory of PM_(10) and PM_(2.5) for total 25 cities of the YRD in 2010 was established. The total emission of PM_(10), PM_(2.5) were 1006kt and 643kt, respectively. At the same time, we firstly gave the detailed speciation of PM_(2.5), which is important for the research of haze formation and radioactive forcing. Composite speciation profiles for more than 20 subsectors have been gotten from numerous literatures, of which more than 70% came from Chinese local measurements. For the YRD region in 2010, the major PM_(2.5) species are OC, EC and sulfate, with 136.9kt, 75.0kt and 74.5kt, respectively.
