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.
