Résumé

Abstract.: Four hundred and thirty-five white suckers were collected from 24 lakes in 7 regions (Wawa, La Cloche, Parry Sound, Algonquin, Muskoka, Haliburton, North Bay) of Ontario, concurrent with measurement of pH, alkalinity and 18 metals and ligands. Lakes Summit and Moran have been contaminated by the dumping of mine tailings. One hundred and seventy-eight fish of six additional species were collected from two of the lakes. Vertebral centra were analyzed by neutron activation analysis. Manganese concentration in lake water was correlated with [H+], Y = 0.024 + 5914X, r2 = 0.79, p < 0.0001, n = 22. In vertebral centra, [Mn] was similar among white suckers from the same lake, but with large differences between lakes (range of population means, 0.223 to 2.42 meq,100g?1 dw). Bone [Mn] was correlated positively with lake [Mn] (r2 = 0.55, p < 0.0001) and negatively with DOC (r2 = 0.36, p < 0.01); lake [Mn] and DOC were not correlated. In stepwise multiple regression, lake [Mn] + DOC + alkalinity accounted for 87% of the variance in bone [Mn]. Concentration factors, calculated as bone [Mn] ÷ lake [Mn] were 1,000 to 4,000X for many fish populations, with the lowest values from the two tailings-contaminated lakes, and the highest C.F.'s from lakes of lowest [Mn] in water, implying some degree of regulation of Mn uptake by the fish. Bone [Mn] of pelagic and littoral fishes were significantly lower than those found in the benthic-feeding white suckers.
