【摘要】 文章对环境空气挥发性有机物(VOCs)进行研究,筛选出了在VOCs浓度总和中占比大的前10种因子。分析了VOCs浓度变化趋势,与大气压、气温的变化关系不明显,与湿度的变化有相似之处,但其峰值或谷值不对应;与臭氧变化形态较为吻合,两者变化折线相似,除个别点位外,折线的峰值或谷值基本对应。核算了57种原PAMS物质的臭氧生成潜势(OFP),对臭氧生成贡献较大的因子为乙烯、甲苯等。更多还原

【Abstract】 In this paper, the volatile organic compounds(VOCs) in ambient air were studied. The top 10 factors that occupied a larger proportion in the total concentration of VOCs were selected. The change trend of VOCs was analyzed, which was not obviously related to the change of atmospheric pressure and air temperature, but similar to the change of humidity, not corresponding to the peak or valley value. It was more consistent with the change trend of ozone, two broken lines are similar and the peak or valley value basically corresponds to each other except for some individual points. The Ozone Formation Potential(OFP) of 57 kinds of PAMs substances was calculated and the factors contributing to ozone formation were Ethylene, Toluene and so on.更多还原
