A study was done to determine the concentrations of surfactants on the sea-surface microlayer and in atmospheric aerosols in several coastal areas around the Malaysian peninsula. The concentrations of surfactants from the sea-surface microlayer (collected using rotation drum) and from aerosols (collected using HVS) were analyzed as methylene blue active substances and disulphine blue active substances through the colorimetric method using a UV-vis spectrophotometer. The results of this study showed that the average concentrations of surfactants in the sea-surface microlayer ranged between undetected and 0.36+/-0.34 micromol L(-1) for MBAS and between 0.11+/-0.02 and 0.21+/-0.13 micromol L(-1) for DBAS. The contribution of surfactants from the sea-surface microlayer to the composition of surfactants in atmospheric aerosols appears to be very minimal and more dominant in fine mode aerosols.
本研究旨在测定马来西亚半岛周边数个沿海地区的海洋表面微层和大气气溶胶中表面活性剂的浓度。采用旋转滚筒收集海洋表面微层（SMS）中的表面活性剂，采用高效体积采样器（HVS）收集气溶胶中的表面活性剂，再通过分光光度法，使用紫外可见分光光度计对亚甲蓝活性物质（MBAS）和二硫代丁二酸盐活性物质（DBAS）进行显色分析。研究结果表明，海洋表面微层中表面活性剂的平均浓度在无法检出和 0.36+/-0.34 微摩尔/升（MBAS）之间，海洋表面微层中表面活性剂对大气气溶胶中表面活性剂组成的贡献微乎其微，而在细颗粒气溶胶中则更为明显。
