| 中文摘要 |
| 基于四川省环境统计调查数据和相关统计资料,利用排放因子法计算得到2011年四川省典型人为源VOCs的排放量及其地区分布情况,同时还估算了各污染源排放的VOCs的臭氧生成潜势与二次有机气溶胶生成潜势. 四川省典型人为污染源VOCs排放总量为482 kt,其中生物质人为燃烧源、溶剂使用源、工业过程源、化石燃料分配源、固定化石燃料燃烧源排放量分别为174、153、121、21和13 kt; 溶剂使用源中,建筑墙壁涂料使用、家具、木器装修以及人造板制造为主要排放行业; 工业过程源中,19.4%的VOCs排放量来自于制酒行业. 四川省各地区排放数据中,成都市排放量最高为112 kt. 四川省臭氧生成潜势总量为1930 kt. 二次有机气溶胶生成潜势中,溶剂使用排放源贡献50.5%,生物质人为燃烧源与工业过程源的贡献均为23%左右,化石燃料分配和固定化石燃料燃烧源分别贡献1.0%和1.4%. |
| 英文摘要 |
| Based on Sichuan province environmental statistical survey data and other relevant activity data, volatile organic compounds(VOCs) emissions from typical anthropogenic sources in Sichuan province were calculated for the year of 2011 by applying the emission factor method. Besides, ozone and secondary organic aerosol formation potentials of these typical anthropogenic sources were discussed. The total VOC emission from these sources was about 482 kt in Sichuan province, biomass burning, solvent utilization, industrial processes, storage and distribution of fuel, and fossil fuel combustion contributed 174 kt, 153 kt, 121 kt, 21 kt and 13 kt, respectively; architecture wall painting, furniture coating, wood decoration painting and artificial board were the major emission sectors of the solvent utilization; while for the industrial processes, 19.4% of VOCs emission was from the wine industry. Chengdu was the largest contributor compared to the other cities in Sichuan, whose VOCs emission from these typical anthropogenic sources in 2011 was 112 kt. OFP of these sources was 1930 kt altogether. Solvent utilization contributed 50.5% of the total SOA formation potentials, biomass burning and industrial processes both contributed about 23%, with storage and distribution of fuel and fossil fuel combustion accounting for 1% and 1.4%, respectively. |
