摘要
2020年5月至11月对增城经济技术开发区核心区域开展VOCs走航,对该区域VOCs组成特征和VOCs异常点位进行监测和分析,结果表明,该区域ΣVOCs浓度均值为74μg/m3处于较低水平;区域VOCs组成中,苯系物占比最大为61.1%;其次为烯烃占比21.1%,再次为含氧含氮烃占比11.9%;在走航过程中捕捉到6个ΣVOCs峰值浓度为1730~16141μg/m3的异常点位,其臭氧生成贡献较高关键物种为甲苯、二甲苯、苯乙烯。
The mobile measurement of ambient volatile organic compounds(VOCs)was conducted in the core area of Zengcheng Economic and Technological Development Zone from May to November in 2020. The composition and excessive emission of VOCs were monitored and analyzed. Results show that the average concentration of ΣVOCs was 74 μg/m3, which was in the low level. Among the VOCs, benzene accounted for the largest proportion of 61.1 %, followed by olefins(21.1 %), and oxygen-containing and nitrogen-containing hydrocarbons(11.9 %). Six excessive emissions of VOCs were measured with peak concentrations ofΣVOCs from 1730 to 16141 μg/m3. Toluene, xylene, and styrene were the key species to contributed higher ozone generation.
