Toxicity of perfluorinated carboxylic acids for aquatic organismsToxicity of perfluorinated carboxylic acids with carbon chain C8to C12were tested with oligochaetaTubifex tubifex.Toxicity was evaluated as the exposure time ET50from onset of damage of the oligochaeta in saturated aqueous solutions. The ET50fluctuated between 25 and 257 minutes. No statistically significant difference was found among the C8, C9and C12acids (ET50between 143 and 257 minutes with large standard deviation). The acids with carbon chain C10and C11induced the effect significantly quicker (25 to 47 minutes). No acute toxicity measured in the three-minute test was observed in any case.
