摘要: 利用排放因子法和浓度实测法,研究厦门市挥发性有机物(VOCs)的排放特征。2013年移动源、植物、工业源排放VOCs所占的比例分别为47.0%、33.9%、19.1%;同时,植物排放的稀烃比机动车高1倍;利用过氧乙酰硝酸酯(PAN)的特性研究了本地区光化学污染过程;揭示了本地区植物排放的VOCs比移动源和本地工业源更容易产生光化学污染的特点以及O3的区域传输特征,提出优化树种减少光化学污染的建议措施。Abstract: The emission characteristics of VOCs in Xiamen were studied by the analysis of measured concentrations and the emission factors. The percentages of VOCs emissions of moving sources,plant source and industrial source were 47. 0,33. 9, 19. 1 respectively, and olefins emissions from plant are one time more than vehiche. The characteristics of PAN was analyzed to study the photochemistry pollution process. The results suggested that VOCs emitted by plant source was more easily to induced photochemical pollution and characteristics of regional transmission of O3 were also revealed,the photochemistry pollution can reduce by the optimized tree species.
