| 英文摘要 | New industrial parks, including fine chemical, medical manufacturers, etc., are emerging in modern cities in China, whereas their emissions and impacts have not been fully illuminated. In this study, ambient volatile organic compounds (VOCs) in Huizhou were measured in three functional zones, namely new industrial, roadside, and residential zones. The average mixing ratios of total VOCs were as follow: industrial (56.22 +/- 15.06 ppbv) > roadside (39.30 +/- 12.96 ppbv) > residential (26.03 +/- 7.31 ppbv). The ozone formation potential (OFP) and secondary organic aerosol formation potential (SOAP) of VOCs in the industrial zone were 1.5-2.3 and 1.7-3.1 times those in the other zones, respectively. Aromatics contributed the most to OFP (39.8 %- 44.8 %) and SOAP (78.9 %- 91.0 %), with much less contributions to VOCs mixing ratios (18.3 %- 21.2 %). Naphthalene was the most abundant aromatic species across the three zones and ranked among the top contributors to OFP and SOAP among all VOCs species. Source apportionment identified that new industrial emissions and solvent use was the largest VOCs contributor in the industrial zone (53.9 %), traffic-related emissions dominated in the roadside zone (40.7 %), while new industrial and traffic-related emissions contributed similar in the residential zone (32.9 % and 34.7 %, respectively). The carcinogenic and non-carcinogenic risks of hazardous VOCs were above the acceptable threshold, primarily due to new industrial and traffic-related emissions. Our results sug- gested to strengthen the control of new industrial emissions and aromatics sources in Huizhou city to improve air quality and protect human health. |
