Bioconcentration of aluminium in fish is a function of the water quality
(e.g. pH and total organic carbon). Estimated steady-state
bioconcentration factors (BCFs) for aluminium in brooktrout (Salvelinus
fontinalis) were 215 at pH 5.3, 123 at pH 6.1 and 36 at pH 7.2. These
BCFs are inversely related to pH. The maximum observed factors BCFs were
232 at pH 5.3, 153 at pH 6.1 and 46 at pH 7.2. When transferred to water
of the same pH but with no added aluminium, the brook trout eliminated
aluminium from tissues more rapidly at pH 5.3 than at 6.1 and 7.2.
