    Distribution of linear Alkylbenzenes (LABs) in sediments of Sarawak and Semnulan rivers, Malaysia
    (Thai Society of Higher Eduation Institutes on Environment, 2012) Sami Muhsen Magam; Mohamad Pauzi Zakaria; Normala Halimoon; Najat Masood; Murad Ali Alsalahi
    The current study is one of the first studies evaluating the levels of linear alkylbenzenes (LABs) in surface sediments of Sarawak and Sembulan rivers which are located in the east coast of Malaysia. The LABs, which are molecular tracers of sewage contamination, were measured in 15 surface sediment samples collected from these rivers. The samples were extracted, fractioned and analyzed by gas chromatography mass spectrometry (GC-MS).

    This study aims to determine the levels of methylene blue active substances (MBAS) and ethyl violet active substances (EVAS) as anionic surfactants and of disulphine blue active substances (DBAS) as cationic surfactants in the surface microlayer (SML) around an estuarine area using colorimetric methods.
