Determination of heavy metals in water, sediment and fishes of Bakun Hydroelectric Reservoir

In this study, the concentration of selected metals (Cd, Cu, Fe, Hg, Mn, Se and Zn) in water, sediment and fishes of Bakun hydroelectric reservoir and the adjacent vicinity were determined. Heavy metals were analysed using a flame atomic absorption spectrophotometer and a mercury analyser. In water,...
