Atomic absorption spectrometric determination of zinc, copper, and selenium in fish from Lake Tanganyika, Burundi, Africa.
Atomic absorption spectrometric determination of zinc, copper and selenium in fish from Lake Tanganyika (Burundi) shows that, although this lake is not polluted, trace element intake by fish contributes an important part of the elemental intake by man. No correlations were found between trace element levels in the fish and fish lipid and protein content. Copper and zinc were positively and highly correlated (P less than 0.005). Interspecies comparison for trace element content of fish samples is discussed. Unless the level of water pollution is taken into account, intraspecies variation cannot be evaluated.
