| 英文摘要 | Atmospheric mixing ratios of carbonyl sulfide (COS) in Beijing were intensively measured from March 2011 to June 2013. COS mixing ratios exhibited distinct seasonal variation, with a maximum average value of 849 +/- 477 pptv in winter and a minimal value of 372 +/- 115 pptv in summer. The seasonal variation of COS was mainly ascribed to the combined effects of vegetation uptake and anthropogenic emissions. Two types of significant linear correlations (R-2 > 0.66) were found between COS and CO during the periods from May to June and from October to March, with slopes (Delta COS/Delta CO) of 0.72 and 0.14 pptv/ppbv, respectively. Based on the emission ratios of COS/CO from various sources, the dominant anthropogenic sources of COS in Beijing were found to be vehicle tire wear in summer and coal burning in winter. The total anthropogenic emission of COS in Beijing was roughly estimated as 0.53 +/- 0.02 Gg/year based on the local CO emission inventory and the Delta COS/Delta CO ratios.
