【摘要】 调查了珠江三角洲典型皮革厂生产过程中不同车间PM10的污染水平,并采用超声萃取和GC-MS联用技术研究了PM10中半挥发性特征有机污染物的含量和成分谱.在所采集的PM10样品中共检测出46种有机化合物,包括苯酚类、醇类、多环芳烃类、酸类、酰胺类和酯类等;真皮水场车间、真皮涂饰车间和人造皮革车间的PM10浓度分别为678.5、454.5和498.6μg.m-3,其颗粒相中有机物质量浓度分别为10.04、6.89和14.21μg.m-3;真皮水场车间以酯类和酰胺类物质所占比重较大,分别为43.47%和36.51%,真皮涂饰车间以酯类和醇类物质所占比重较大,分别为52.52%和16.16%,人造革生产车间以酯类和酰胺类物质所占比重较大,分别为57.07%和24.17%;在得到的具体成分谱中,水场车间以9-十八碳烯酰胺含量最高,为26.15%,真皮涂饰车间以邻苯二甲酸二辛酯的含量最高,为44.19%,而人造革车间的丁烯二酸二(2-乙基己基)酯和1-羟基哌啶含量明显高于其它2个车间.更多还原

【Abstract】 Through investigating current air pollution condition for PM₁₀ in every factories of different style leather plants in Pearl River Delta,characteristic profile of semi-volatile organic compounds in PM₁₀ emitted from leather factories and their contents were researched by using ultrasonic and gas chromatography and mass spectrum technology.The 6 types of organic compounds containing 46 species in total were found in the collected samples,including phenyl compounds,alcohols,PAHs,acids,esters and amides.The concentrations of PM₁₀ in leather tanning plant,leather dying plant and man-made leather plant were 678.5,454.5,498.6(μg·m^-3) respectively,and concentration of organic compounds in PM₁₀ were 10.04,6.89,14.21(μg·m^-3) in sequence.The more important type of pollutants in each leather plants had higher contribution to total organic mass as follows,esters and amides in tanning plants profile account for 43.47% and 36.51% respectively;esters and alcohols in dying plants profiles account for 52.52% and 16.16% respectively;esters and amide in man-made leather plant have the highest content and account for 57.07% and 24.17% respectively.In the aerosol organic source profiles of tested leather plants,9-octadecenamide was the abundant important species with the weight of 26.15% in tanning plant,and Bis（2-ethylhexyl） phthalate was up to 44.19% in the dying plant,and Bis（2-ethylhexyl） maleate and 1-hydroxy-piperidine had obviously higher weight in man-made plant than the other two plants.更多还原
