英文摘要	The concentrations of alpha-, beta-, and gamma-hexabromocyclododecane diastereomers (HBCDs) in gas phase and particulate phase of Dalian urban air, China, were monitored from September 2016 to August 2017 with high-volume active sampler. The total concentration of aHBCDs (gas phase + particulate phase) ranged from 15.47 to 43.57 pg m(-3), with an average of 27.07 pg m(-3), and 73.39-96.76% of the total HBCDs were found in the particulate phase. No matter in gas phase or in particulate phase, alpha-HBCD was the predominant component in all, and there was a good negative correlation between the relative contribution of alpha-HBCD to aHBCDs and that of gamma-HBCD to aHBCDs. The average ratios of the air concentration of alpha-HBCD to gamma-HBCD were comparable with those found in decorative polystyrene, which indicated that HBCDs in outdoor air of Dalian probably came from indoor air and ventilation air from inside of buildings coupled with the already present contamination in background air. There were clear seasonal differences in the HBCD concentrations. Spearman's rank correlation analysis between the concentrations of HBCDs with meteorological parameters was conducted. The exposure risk of HBCDs was evaluated, which illustrated that the estimated exposure of HBCDs via the outdoor air in Dalian was well below the reference doses (200 ng kg(-1) bw day(-1)) derived by the US National Research Council.
