| 内容記述 | Petroleum hydrocarbon pollution in the marine environment has been a major concern in recent years. A 50-year history of industrialization process in Malaysia is rapidly spreading to the East Coast regions. Some components of petroleum hydrocarbon had been demonstrated to disrupt endocrine systems in human. Very few measurement on compounds specific hydrocarbon has been made for the characterization and composition in the East Coast’s rivers and estuaries. A total of 14 surface sediment samples were collected in August, 2006 from the Kelantan, Besut and Terengganu rivers. The samples were dried, soxhlet extracted, fractionated and injected into GC-FID and GC-MS for alkanes and polycyclic aromatic hydrocarbons (PAHs), respectively. In general, elevated concentrations hydrocarbons were found in all stations located in the vicinity of urban runoffs for all rivers. The concentrations of aliphatic hydrocarbons range from 1000 to 7168000 ng/g (dry wt.) and PAHs concentration ranged from 58 to 1689 ng/g (dry Wt.) for the rivers. The PAHs patterns in urbanized stations suggest the dominance of low molecular weight PAH components (2.4 rings). Based on MP/P ratio, the source of hydrocarbons influenced by the city runoffs are mostly petrogenic origin. The sources of hydrocarbons on the upstream and downstream stations have been to be of pyrogenic origin. In general, the concentrations of PAHs and alkanes for a number of stations in this study are comparable to more polluted sites in Malaysia. In conclusion, all three rivers showed low to moderate petroleum hydrocarbon contamination. These results suggested that immediate remedial measure in preventing further contamination has to be implemented by local, state and federal agencies. | |||||
