A high oral concentration of 10g Al kg −1 dry weight promoted toxicant accumulation in the muscle, gill, liver, kidney and mucus of trout. One mortality occurred and only a small proportion of the exposure dose was retained by the fish. The limited acute oral toxicity of Al implies that contamination levels found in food species are unlikely to be acutely toxic to wild trout.
