挥发性有机物(VOCs)是臭氧和二次有机气溶胶的重要前体物,道路移动源是我国大气VOCs的重要来源之一.本文在调研文献基础上,总结国内道路移动源VOCs成分谱建立方法,包括成分谱实测方法和成分谱整合方法.针对现阶段道路移动源VOCs排放已发展至在燃料的基础上区分排放标准,本文阐述实测条件下不同排放标准汽油车和柴油车的VOCs成分谱,指出现有成分谱的不足之处;对比基于实测数据和基于数据整合的道路移动源VOCs的差异,提出当前需建立统一的采样分析方法,更新现有道路移动源VOCs成分谱数据库.
Volatile organic compounds(VOCs)are critical precursors for ozone and secondary organic aerosols,among which on-road mobile source is one of the significant contributors to atmospheric VOCs in China.Based on a review of literature,this study summarizes the methods for the establishing VOCs profiles for on-road mobile source in China,including both direct measurement method and integrated method.Considering that the current emission standards for VOCs from on-road mobile source have evolved to differentiate based on fuel,this study describes the VOCs profiles from gasoline and diesel vehicles under different emission standards,highlighting the limitations of existing source profiles.By comparing the differences between measurement-based and integration-based VOCs from on-road mobile source,it is recommended to establish a unified sampling and analysis method,and update the existing source profile databases for on-road mobile source VOCs.
