Abstract
Sewage pollution is one of major concerns of coastal and shoreline settlements in Southeast Asia, especially
Brunei. The distribution and sources of LABs as sewage molecular markers were evaluated in surface sediments
collected from Brunei Bay. The samples were extracted, fractionated and analyzed using gas chromatographymass
spectrometry (GC-MS). LABs concentrations ranged from 7.1 to 41.3 ng g−1 dry weight (dw) in surficial
sediments from Brunei Bay. The study results showed LABs concentrations variably due to the LABs intensity
and anthropogenic influence along Brunei Bay in recent years. The ratio of Internal to External isomers
(I/E ratio) of LABs in sediment samples from Brunei Bay ranged from 0.56 to 2.17 along Brunei Bay stations, indicating
that the study areaswere receiving primary and secondary effluents. This is the first study carried out to
assess the distribution and sources of LABs in surface sediments from Brunei Bay, Brunei.
