| 中文摘要 |
| 为满足城市臭氧污染的精准管控需求，基于实际调研的人为源活动水平数据与国内外VOCs源成分谱，采用排放因子法构建了沧州市2021年人为源VOCs组分排放清单，并系统分析了沧州市人为源VOCs排放特征和臭氧生成潜势（OFP）.结果表明，2021年沧州市人为源VOCs排放量为6.97万t；排放量最高的源类为工艺过程源（66.8%）；排放量最高的组分为烷烃、芳香烃和OVOCs，其中烷烃主要来源于石油、煤炭及其他燃料加工业，芳香烃主要来源于黑色金属冶炼和压延加工业，OVOCs主要来源于橡胶和塑料制品业；沧州市人为源VOCs的OFP为20.74万t，芳香烃和工艺过程源为OFP排放主要贡献组分和主要贡献源类.其中对沧州市OFP排放贡献率前10名的物种分别是：间/对-二甲苯、甲苯、丙烯、乙烯、邻-二甲苯、1-丁烯、乙苯、戊烷、1，2，4-三甲苯和甲基乙基酮.空间分布上，渤海新区和任丘市的VOCs排放和OFP显著高于其他区县，研究区域内VOCs排放高值点主要集中分布于各区县工业园区所在地.研究所构建的人为源VOCs组分清单可为沧州市臭氧污染治理及精细化管控政策制定提供数据支撑. |
| 英文摘要 |
| Accurate emission inventories are essential for effective ozone pollution control in urban areas. Cangzhou has been frequently plagued by volatile organic compounds （VOCs） pollution along with its rapid economic development and urbanization in recent years. In this study， a high spatial resolution VOCs emission inventory for Cangzhou was established for the year 2021 using source-specific emission factors and the latest activity data from different sources. The anthropogenic sources considered in this study were classified into seven major sources and 29 subcategories. The results indicated that a total of 69.7 kt of anthropogenic VOCs were emitted in Cangzhou in 2021. The industrial process source was identified as the largest emission source category， accounting for 66.8% of the total emissions. The main components of Cangzhou VOCs were alkanes， aromatics， and oxygenated volatile organic compounds （OVOCs）. Alkanes were mainly from the oil， coal， and other fuel processing industries. Aromatics were mainly from the ferrous metal smelting and rolling processing industry. OVOCs were mainly from the rubber and plastic products industry. The total OFP of anthropogenic VOCs in Cangzhou was 207.4 kt， with the aromatics and industrial processes source being the major contributing components and emission source category. The top 10 species contributing to OFP emissions in Cangzhou were m/p-xylene； toluene； propylene； ethylene； o-xylene； 1-butene； ethylbenzene； pentane； 1，2，4-trimethylbenzene； and methyl ethyl ketone. Spatially， the Bohai New Area and Renqiu City were the top two emitters of VOCs. High VOCs emission regions were concentrated in industrial parks within various districts and counties. The anthropogenic VOCs component inventory constructed in this study provided critical data support for ozone pollution control and refined policy measures in Cangzhou. |
