文摘 中等挥发性有机物(IVOCs)作为二次有机气溶胶的重要前体物倍受关注。柴油机(包括船舶)是重要的IVOCs排放源,但其排放特征和环境影响亟待研究。本文选择船舶活动密集的上海洋山港为研究区,采集夏季(2016年8月~9月)和冬季(2017年1月~2月)环境空气IVOCs样品,分析其浓度、组成和季节变化特征,探讨船舶排放对港口环境空气IVOCs的贡献,并评估杭州G20峰会期间船舶管控措施的实际效果。结果表明: (1)上海洋山港环境空气IVOCs平均浓度为(5.1±0.8) μg/m~3,其中,正构烷烃和多环芳烃分别占4.3%±0.8%和1.6%±0.5%,其余为不能单体识别的组分(UCM),包括支链烷烃(26.9%±3.9%)和剩余UCM(67.2%±4.4%); (2)时间上,洋山港IVOCs浓度夏季((5.7±0.3) μg/m~3)高于冬季((4.6±0.7) μg/m~3), “上午”(采样时段7:30~15:30)高于“下午”(15:30~23:20)和“夜晚”(23:30~7:20),显示船舶活动对港口环境空气的重要影响; (3)杭州G20会期(2016年9月4日~5日)相比于会前(8月22日~29日),洋山港IVOCs、OC、SO_2和NO_2浓度分别下降了8%、47%、31%和19%,表明船舶排放管控措施具有较显著的减排效果。
其他语种文摘 There are serious concerns about intermediate-volatility organic compounds (IVOCs), which are important precursors of secondary organic aerosols. Diesel engines, such as those on ships, are important sources of IVOCs, and the associated emission characteristics and impacts on ambient air need to be understood. In this study, atmospheric IVOC samples were collected at Yangshan Deep-Water Port in Shanghai during summer (late August to early September 2016, and during the G20 Summit in Hangzhou, China) and winter (January and February, 2017). Concentration levels, components, and seasonal variation characteristics of IVOCs were analyzed. The contribution of IVOCs from shipping emissions to ambient air in the harbor area was then discussed, and the actual effect of controlling measures on shipping emissions during G20 Summit session (September 4-5, 2016) was also evaluated. Results showed that: (1) The average concentration of atmospheric IVOCs in Yangshan Deep-Water Port was (5.1 ± 0.8) μg/m~3; 4.3% ± 0.8% of this amount was attributed to n-alkanes and 1.6% ± 0.5% to aromatic hydrocarbons, whereas the remaining amount was an Unresolved Complex Mixture (UCM). The UCM was comprised of two parts: an unspeciated b-alkanes accounting for 26.9% ± 3.9%; and residual UCM, which accounted for 67.2% ± 4.4%. (2) With respect to temporal characteristics, the average concentration of atmospheric IVOCs was higher in summer ((5.7 ± 0.3) μg/m~3) than winter ((4.6 ± 0.9) μg/m~3), and higher in “morning” (sampling time 07:30 - 15:30) than during “afternoon” (sampling time 15:30 - 23:30) and “night” (sampling time 23:30 - 7:20), which shows the strong influence of ship emissions on ambient air in the harbor. (3) Due to the controlling measures of ship emissions during Hangzhou G20 summit (September 4 - 5, 2016), there were evident declines in concentrations of IVOCs, OC, SO_2, and NO_2 by 8%, 47%, 31%, and 19%, respectively, which shows the significant emission reduction effect.
