摘要
挥发性有机物(volatile organic compounds,简称VOCs)是造成我国城市大气污染的主要因素之一,包括众多行业活动在内的工业源是VOCs污染的重要来源.本研究在2007年VOCs污染源普查结果的基础上,选取了包括汽车制造、包装印刷、装备业制造、电子制造、家具制造以及生物制药等重点VOCs污染排放行业,针对每一行业,选取数家代表性企业,进行现场调研和在线监测分析.研究结果表明,这些行业排放VOCs浓度水平为中低水平,总排放浓度TVOCs一般小于1000mg/m3,每一行业特征排放物不尽相同.排放的VOCs主要包括苯系物、酯类、醇类、酮类、烯烃、氯代烃、烷烃等,其中以苯系物检出频率最高.从降低大气氧化活性,改善空气质量角度来看,汽车制造应为优控行业;从保护人体健康方面来看,家具制造和短链氯代烃应为优控行业和优控污染物.污染控制分析认为,研发低成本、高效的治理技术和建立健全相关的排放标准/法规是当前行业VOCs排放控制工作的关键所在.
