Abstract

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 ∑ 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. Total concentration of PAHs in the sediment of east coast of Peninsular Malaysia were in the range of between 0.26 to 0.59 µg/g dry weight, which is considered by Ulun et. al. as slightly polluted [18]. Several ratio of PAHs species concentration such as Phen/Anth, Fl/FL+Py and ∑MePhen/Phen were applied to identify sources of the anthropogenic pollutants, which indicate that the source is pyrolytic (petroleum combustion.



Pencemaran polisiklik aromatik hidrokarbon (PAH) di beri perhatian disebabkan oleh sifatnya yang gigih dalam ekosistem marin, ia boleh menyebabkan kesan buruk kepada kehidupan marin dalam jangka masa panjang. Pengukuran kepekatan PAH dalam sediment di pantai timur Semenanjung Malaysia dijalankan dalam kajian ini. Sepuluh lokasi telah dipilih disepanjang kawasan pantai timur untuk diambil sampel sedimen menggunakan pensampel cangkup. PAH daripada sampel sedimen dijalankan ekstraksi soxhlet menggunakan campuran heksana dan diklorometana (DCM). Pemisahan dilakukan menggunakan turus silica/alumina. 17 sebatian PAH ditentukan dengan menggunakan Gas Kromatografi-Spektrometer Jisim (GC-MS model QP5050A). ∑ PAH yang diperolehi adalah diantara 0.26µg/g hingga 0.59µg/g berat kering. Data daripada kajian ini menunjukan punca utama pencemaran PAH di dalam sedimen diperairan pantai timur Semenanjung Malaysia berasal dari sumber pirolitik.
