摘要: Abstract Size-segregated PM 10 samples were collected in Guangzhou, China during autumn of 2014. Nine amines, including seven aliphatic amines and two heterocyclic detected using a gas chromatography-mass spectrometer after derivatization by benzenesulfonyl chloride. The total concentration the nine (Ʃamines) was 79.6–140.9 ng m −3 . most abundant species methylamine (MA), which had 29.2–70.1 ng m MA, dimethylamine (DMA), diethylamine (DEA) dibutylamine (DBA) predominant accounted for approximately 80% Ʃamines each size segment. Two pyrrolidine (PYR) morpholine (MOR), all average concentrations 1.14 ± 0.37 1.89 ± 0.64 ng m , respectively, particles with aerodynamic diameters 7.9 ± 1.6 μg m −2 d −1 0.084 ± 0.0021 cm s respectively. results this study provide essential information on contribution to secondary organic aerosols dry removal mechanisms urban areas.
