About half of PM2. 5 source apportionment work in China used chemical mass balance (CMB) model based on the statistics of previous relevant publications. Source profile is one of key input in CMB model. However, there is great lack of local source profiles in China. Often source profiles abroad or nonlocal source profiles have to be borrowed and applied in CMB to solve PM2. 5 sources in China. This study aims to establish new local industrial sources profiles in Shanghai for future source apportionment work in this area. According to emission inventory in Shanghai, industrial source is a major contributor to PM2. 5 among different source categories. An iso-kinectic sampling dilution tunnel system was used to collect PM2. 5 source samples at four sites including power plant 1 (PP1), power plant 2 (PP2), sintering plant (SP), and furnace plant (FP). PM2. 5 mass, ions, OC, EC, and elements were analyzed and quantified in these new industrial source profiles.
