Anthropogenic activities that happen in Terengganu River were contributed to sediment pollution at that area.  The sediment pollution occurred when sediment are additional influenced with chemical adsorption between the metals, grain size, and organic matter. Thus, this study was conducted to assess the metal pollution using Enrichment Factor (EF) and Pollution Load Index (PLI) and compared with the previous study. A total of 15 sediment samples were collected from 5 different rives and metal concentration were analyzed using flame Atomic Absorption Spectrometer (ASS). The metal concentration ranged as followed: Cr (0.48-12.80 mg/kg), Cu (0.38-15.20 mg/kg), Mg (202.00-2769.00mg/kg), K (63.36-1730.00 mg/kg), Mn (4.27-33.70 mg/kg), Zn (2.05-31.30 mg/kg) and Cl (141.00-584.00 mg/kg) respectively. Enrichment Factor (EF) and Pollution Load Index (PLI) were used as a pollution indicator to access the sediment pollution in selected Terengganu Rivers. The mean Enrichment Factor (EF) value indicated in decrease order Cl (34.70) > Zn (23.44) > Cu (10.37) > Cr (1.95) > K (1.58) > Mg (1.16)> Mn (0.87). Meanwhile, Pollution Load Index (PLI) value showed below than 1 in all sampling stations. When compared with previous study, Mg  and Cl metals need to take further action due to dramatically increased within seven years. The output from this study will be useful for environmental management at Terengganu Rivers.

Rapid development of industrialization and urbanization along Sungai Kerteh and Sungai Pakawas become a problem due to metal pollution. Namely, anthropogenic activities nearby SungaiKerteh and Sungai Paka were contributed to heavy metals pollution into those rivers. The aims forthis study were to determine the selected heavy metals contamination in water samples andcompared with National Water Quality Standard for Malaysia (NWQS). A total of 8 watersamples were collected from both rivers and heavy metal concentration were analyzed usingflame Atomic Absorption Spectroscopy (ASS). Four parameters of physical chemical propertieswere also analyzed which are pH, temperature, dissolved oxygen and turbidity. The ranges ofphysical chemical properties are pH (7.84-8.78), temperature (31.20 -38.70 oC), dissolved oxygen(27.90-107.20%) and turbidity (1.83-10.5 NTU) respectively. The mean of heavy metalsconcentration was ranged as followed; As (2323.00 ug/L) > Hg (571.93 ug/L) > Pb (402.13 ug/L)> Zn (87.13 ug/L) >Cr (74.63 ug/L) > Cu (48.50 ug/L) > Ni (17.25 ug/L) > Cd (11.38 ug/L).When compared with NWQS, most of metals (Cu, Pb, Ni and Zn) are below the NWQS thresholdlimit except As, Cd, Cr and Hg. The output data from this study can be used as database forcontinuous monitoring at both rivers.
