Abstract The toxicity of aluminum on the phytoplankton species Monoraphidium griffithii and M.dybowskii (Chlorophyceae) was investigated. At pH 6.8 and low humus concentration, the growth of both species was reduced at 100–200 μg Al/l, whereas at pH 4.8 only the growth of M.griffithii was affected. The toxicity on the two species showed different relations to the pH-value. The results, supported by analyses of Al-fractions — total acid soluble, total monomeric and none-labile monomeric Al — indicate that the Al-toxicity is species-dependent, and that aluminium, soluble at neutral pH-conditions, can be toxic to the phytoplankton.
