This study was conducted to determine the composition of surfactants in the sea-surface microlayer (SML) and atmospheric aerosol around the southern region of the Peninsular Malaysia. Surfactants in samples taken from the SML and atmospheric aerosol were determined using a colorimetric method, as either methylene blue active substances (MBAS) or disulphine blue active substances (DBAS). Principal component analysis with multiple linear regressions (PCA-MLR), using the anion and major element composition of the aerosol samples, was used to determine possible sources of surfactants in atmospheric aerosol. The results showed that the concentrations of surfactants in the SML and atmospheric aerosol were dominated by anionic surfactants and that surfactants in aerosol were not directly correlated (p>0.05) with surfactants in the SML. Further PCA-MLR from anion and major element concentrations showed that combustion of fossil fuel and sea spray were the major contributors to surfactants in aerosol in the study area.
本研究旨在确定马来西亚半岛南部地区海-气界面（SML）和大气气溶胶中表面活性剂的组成。采用比色法（MBAS 或 DBAS）测定了从 SML 和大气气溶胶中采集的样品中的表面活性剂。利用主成分分析与多元线性回归（PCA-MLR），并结合气溶胶样品中的阴离子和主要元素组成，确定了大气气溶胶中表面活性剂的可能来源。结果表明，SML 和大气气溶胶中表面活性剂的浓度主要由阴离子表面活性剂主导，且气溶胶中的表面活性剂与 SML 中的表面活性剂之间无直接相关性（p>0.05）。进一步基于阴离子和主要元素浓度的 PCA-MLR 表明，在研究区域，化石燃料燃烧和海水喷雾是气溶胶中表面活性剂的主要来源。
