The polycyclic aromatic hydrocarbons (PAHs) are pollutants of concern due to their persistent in the marine ecosystem, thus
its can cause long-term adverse effect to the marine life. In this study the concentrations of PAHs in east coast Peninsular
Malaysia sediments were determined. About ten stations along the east coast of the coastal area were selected to collect
sediment samples using grab sampler. The PAHs from the sediment samples were soxhlet extracted using mixture of hexane
and dichloromethane (DCM). Fractionation was done using the silica-alumina column. About 17 compounds of the PAHs
were determined using the Gas Chromatography-Mass Spectrometer (GCMS model QP5050A). The Σ PAHs was found in
range between 0.26μg/g to 0.59μg/g dry weight. The data from the study signified that the main source of PAHs in the
sediment of the east coast peninsular Malaysia is originated from the pyrolytic source
