摘要 | To ensure good air quality for the 2014 AsiaPacific Economic Cooperation (APEC) summit, stringent emission controls were implemented in Beijing and its surrounding regions, leading to a significant reduction in PM2.5 loadings. To investigate the impact of the emission controls on aerosol chemistry, high-volume PM2.5 samples were collected in Beijing from 8 October to 24 November 2014 and determined for secondary inorganic aerosols (SIA, i.e., SO42-, NO3-, and NH4+), dicarboxylic acids, keto-carboxylic acid, and alpha-dicarbonyls, as well as stable carbon isotope composition of oxalic acid (C-2). Our results showed that SIA, C-2, and related secondary organic aerosols in PM2.5 during APEC were 2-4 times lower than those before APEC, which is firstly ascribed to the strict emission control measures and secondly attributed to the relatively colder and drier conditions during the event that are unfavorable for secondary aerosol production. |
