北京市大气挥发性有机物(VOCs)的污染特征及来源

摘要

Emission of volatile organic compounds (VOCs) is a significant source of atmospheric pollution and has become one of the most important environmental problems in China,especially in Beijing.In this review,we summarized the pollution situation,including concentrations and sources of VOCs as well as benzene series (BTEX),either under different control measures or not in Beijing in recent years.We also proposed directions for future research.%挥发性有机物(VOCs)的排放是大气污染的重要来源,已经成为我国最重要的环境问题之一,北京市的污染尤为严重.本文对北京市近年来大气挥发性有机物、苯系物的污染情况和来源以及不同控制措施下挥发性有机物的浓度变化进行了总结概括,并对今后的研究进行了展望.
