Abstract The toxicity of natural lake waters contaminated with heavy metals from mining effluents was studied by perfusing water samples through the olfactory organs of Arctic char (Salvelinus alpinus) while recording the olfactory bulbar electrical responses to the standard stimulant, L-serine. Of the five lake waters tested, only Ross Lake, the closest to the mining-smelting site, showed significant depressing effect on the olfactory response at levels as high as 100 times dilution. Chemical analysis of lake waters revealed that Ross Lake had the highest concentrations of heavy metals; 43 μg/1 Cd, 98 μg/1 Cu, <15 μg/1 Ni and 7720 μg/1 Zn. Single component experiments showed that Cu and Cd are probably responsible for most of the depressive effect. The depressive effect of natural lake water was less than that of an artificial lake water composed of heavy metals based on the natural lake concentrations. Possible involvement of complex formation of heavy metals in the reduction of their toxicity is discussed.
