| 摘 要： | 对成都市5类典型溶剂使用行业挥发性有机物(VOCs)进行采样监测,测定了其主要组成成分,得出了各行业的VOCs本地化排放系数.结果表明:芳香烃和含氧VOCs是主要成分,不同行业的特征VOCs组分各有不同;大气化学反应活性较大的物种大部分为芳香烃,其中对/间二甲苯的臭氧生成潜势(OFP)值约为141.88 mg·m~(-3),甲苯的OFP值约为90.90 mg·m~(-3),二者占总OFP的53%;家具制造行业的VOCs排放系数为0.61 kg·件~(-1),汽车喷涂行业VOCs排放系数为3.1 kg·辆~(-1),制鞋行业VOCs排放系数为4.04 g·双~(-1),印刷行业VOCs排放系数为34.7g·kg~(-1)油墨,人造板生产行业VOCs排放系数为3.67 g·m~(-3)人造板.

| Abstract: | VOC emissions compositions from 5 typical industries of solvent use in Chengdu city were measured by field sampling and analysis, in order to obtain their local emissions factors. Results identified that the characterized VOC emissions compositions for each industry were different, whilst aromatics and oxygenated VOCs were the major species. In addition, the aromatics were also identified as the principal species to have a significant impact on atmospheric chemistry reactivity. Two components of the aromatics, i.e., xylene, methylbenzene contributed to 53% of the total ozone formation potential (OFP), in which the former was calculated as 141.88 mg·m-3, the latter as 90.90 mg·m-3. The VOCs emissions factor for local furniture manufacture, vehicles coating, shoemaking, printing, and wood-based panel industry was measured as 0.61 kg per piece, 3.1 kg per vehicle, 4.04 g per pair, 34.7 g per kg printing ink, 3.67 g per m3 wood-based panel, respectively. |
