Mercury Concentration of Four Dominant Species in the Bebar Peat Swampy Forest River, Malaysia

B.Y. Kamaruzzaman, M.C. Ong and A.H. Khali

Muscle, stomach and gill from four dominant fish species, Mytus nemurus, Pristolepis fasciata, Ompok bimaculatus and Osteochilus hasseltii, caught from Bebar peat swamp forest river were analyzed for mercury (Hg). The concentration of Hg was measured with a fast and sensitive Flow Injector Mercury Spectrometer (FIMS). The average Hg concentration of all species caught was 0.169 μg g^-1 dry weights, lower than a limit for human consumption recommended by the World Health Organization, 0.5 μg g^-1 dry weights. The mean concentration of Hg was relatively high in stomach (0.28x0.12 μg g^-1 dry weights) followed by gill (0.17x0.06 μg g^-1 dry weights) and lowest in muscle (0.05x0.02 μg g^-1 dry weights). The positive relationship of Hg with fish length and weight suggesting that the accumulation of Hg were formed in the fish.
