抄録: A study has been carried out at the Langat Estuary, Selangor. The primary objective of this research is to determine the sources and concentration of polycyclic aromatic hydrocarbon (PAHs) in the sediments in the Langat Estuary. 6 stations were chosen, beginning at the Estuary and ending at the upstream river of the Langat Estuary. The determination of concentration and compound of PAHs were analyzed by using Gas Chromatography-Mass Spectrometry (GC-MS). The samples were calculated using methylphenanthrene/phenanthrene (MP/P) ratio to determine the sources. The value of less than 1 is the pyrogenic sources and more than 1, consist of petrogenic sources. Total PAHs for sediment samples of Station 1 until Station 6 ranged from 322ng/g to 2480ng/g (dry weight). Furthermore, MP/P ratios for sediment samples had values ranging from 0.88 to 1.27, while L/H ratios for the same samples ranged from 0.25 to 26.96. There were 17 compounds of PAHs detected in the samples. Sediment samples from Station 1 until Station 6 showed an MP/P ratio value of less than 1, with the exception of Station 4 and Station 6. This points out that this area is dominated by pyrogenic sources.
