挥发性有机化合物(VolatileOrganicCompounds)一般是指在101,325Pa标准大气压下,任何沸点低于或等于250qC的有机化合物,简称VOCsllJ。随着工业的发展,我国的挥发性有机污染物的排放量正逐年增加。VOCs对人体健康、环境质量、生产活动等会产生直接危害,在光化学反应下容易形成二次有机气溶胶,导致光化学烟雾、酸雨、城市灰霾等一系列环境问题。2010年国务院发布了《关于推进大气污染联防联控工作改善区域空气质量指导意见》,首次将VOCs作为防控重点污染物。随后,《大气污染防治行动计划》《重点行业挥发性有机物综合整治办法》《挥发性有机物(VOCs)污染防治技术政策》《挥发性有机物排污收费试点办法》H以及系Y ̄VOCs重点行业排放标准等政策和标准的发布,推进了VOCs治理的进一步发展。
