| 中文摘要: |
| 采用GC-MS法测定拉链排咪、塑料制品、包装印刷行业的生产车间无组织VOCs排放，得到3个工业源VOCs源成分谱。结果表明：不同工业源排放的VOCs组分存在明显差异，拉链排咪以苯系物为主，占比3529%，主要污染物为正己烷、二氯甲烷、甲苯；塑料制品中苯系物占比为4735%，甲苯、乙酸乙酯、正己烷为主要污染物；包装印刷中苯系物质量分数高达6367%，甲苯、1，2，4-三甲苯、丙酮为主要污染物 |
| 英文摘要: |
| VOCs fugitive emission from the workshops of zipper， plastics， packaging and printing industries were detected by GC/MS， and VOCs source profiles from 3 industrial sources were obtained. The results showed that the components of VOCs from different industrial sources were significantly different. Benzene series were dominated in zipper industry， which accounted for 35.29% of TVOC. The main pollutants were n hexane， dichloromethane and toluene. Benzene series accounted for 47.35% in plastics industry， toluene， ethyl acetate and n hexane were the main pollutants. The mass fraction of benzene series in packaging and printing industry was up to 63.67%， toluene， 1，2，4 trimethylbenzene and acetone were the main pollutants. |
