Abstract
As Volatile Organic Compounds (VOCs) are one of the precursors of ozone, their distribution and variable concentrations are highly related to local ozone pollution control. In this study, we obtained vertical profiles of VOCs in Shanghai’s Jinshan district on 8 September and 9 September in 2016 to investigate their distribution and impact on local atmospheric oxidation in the near surface layer. Vertical samples were collected from heights between 50 m and 400 m by summa canisters using an unmanned aerial vehicle (UAV). Concentrations of VOCs (VOCs refers to the 52 species measured in this study) varied minimally below 200 m, and decreased by 21.2% from 100 m to 400 m. The concentrations of VOCs above 200 m decreased significantly in comparison to those below 200 m. The proportions of alkanes and aromatics increased from 55.2% and 30.5% to 57.3% and 33.0%, respectively. Additionally, the proportion of alkenes decreased from 13.2% to 8.4%. Toluene and m/p-xylene were the key species in the formation of SOA and ozone. Principal component analysis (PCA) revealed that the VOCs measured in this study mainly originated from industrial emissions.
摘要
挥发性有机物(VOCs)作为环境大气臭氧(O3)的重要前体物,其在环境大气中的浓度以及分布与O3的局地化学生成高度相关。本研究在2016年9月8日和9月9日,通过使用无人机搭载VOCs采样罐的形式,对上海市郊区的50米至400米高度的环境大气进行离线采样分析。VOCs廓线的分析结果显示,环境大气中的VOCs浓度在200米高度之下变化幅度较小,从100米高度到400米高度VOCs浓度能够降低21.2%。对不同高度的VOCs组成成分分析发现,烷烃和芳香烃的占比分别从55.2%和30.5%上升至57.3%和33.0%。但是烯烃的占比却从13.2%下降到8.4%。在对环境大气中不同高度下的VOCs的O3生成潜势(OFP)和二次有机气溶胶(SOA)生成潜势(SOAFP)进行计算发现,苯、间/对-二甲苯是对当地O3和SOA生成贡献最大的关键物种。在使用主成分分析(PCA)方法对当地VOCs来源进行解析发现,当地VOCs主要来自于工业排放。
