摘　　要：以工业密集的珠江三角洲地区为研究对象,通过建立2010~2017年主要工业源VOCs排放趋势清单和成分谱数据集,识别了VOCs总量排放趋势和组分结构变化特征,并探讨了典型工业行业VOCs排放结构与组分特征变化的原因.结果显示,2010~2013年珠三角主要工业源VOCs排放量从38万t上升至41万t,而后由于VOCs减排政策的落实持续下降,2017年降至32万t.VOCs组分以间对二甲苯、甲苯、乙苯等芳香烃、乙酸乙酯、丁酮等含氧VOCs和异丁烷等烷烃组分为主.水性涂料替代和末端治理设施等控制政策对工业源VOCs排放与组分结构均有一定程度的影响,排放结构上,金属表面涂装､家具制造､橡胶与塑料制品等行业排放贡献有所下降,组分结构上,芳香烃组分总体下降显著,而烷烃和OVOCs组分占比上升.The industrial source is one of the major contributors to volatile organic compounds(VOCs)emission,which are the crucial precursors to ozone(O3)and aerosols.Due to several VOC emission control policies enacted in recent years,the industrial VOC emission structure in the Pearl River Delta region(PRD)might have changed greatly.In this study,a long-term industrial VOC emission inventory in the PRD region during 2010~2017 was developed.Based on a time-dependent speciated profile database,the industrial VOC emission inventory was disaggregated into species by sub-sector.The change of industrial VOC emission structure and its cause were also discussed.VOC emissions from industrial sources in the PRD region increased from 380kt in 2010 to 410kt in 2013 but then decreased to 320kt in 2017 due to the implementation of VOCs emission control measures,such as promoting the use of water-based coatings and the installment of exhaust treatment facilities.As a result,emission contributions of metal surface coating industry,furniture manufacturing industry and rubber and plastic products industry,which were dominated by aromatic hydrocarbons,also declined to some extent.The aromatic species of industrial VOCs emission decreased significantly,partly led to the increase of proportions of alkanes and VOCs.These results were informative to develop robust control measures to further control VOC emission in the PRD region.
