Surface sediment samples were collected from 5 different zones of the Langkawi coastal waters, Malaysia to determine the concentration of Lead (Pb) and Copper (Cu) by using the sensitive Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The concentration of heavy metals was compared with the world average concentration of shale values. It was found that the total concentration of Pb was between 12.25 and 71.38 μg g-1 dw with mean concentration value of 41.87±7.30 μg g-1 dw which was two fold higher than the average shale value (20 μg g-1). Statistical analysis showed that the significant variation in Pb concentration between different sampling stations (p |
