The physical and chemical water quality of four rivers in Taman Negara namely Sg. Terenggan, Sg. Keniyam, Sg. Sat and Sg. Tahan are within limits of the recommended Malaysian water criteria for domestic supply. Ten fish species were caught and analysed for heavy metals. Lead, zinc, copper, manganase, iron and cadmium content were determined in the gills, stomach, muscle tissues, bones and tails using Atomic Absorption Spectrophotometric methods. Levels of lead, zinc, copper and iron were high in the tail region. Heavy metal content in fish muscle tissues varied between fish species. The heavy metal contents (g/g wet weight) were generally within these ranges: Pb (0.03-0.70), Zn (6.2-18.9), Cu (0.4-0.5), Mn (0.2-2.3), Fe (0.9-13.1), Cd (0.1-0.2)
