Description of key information

The substance is acutely toxic to aquatic organisms.

Long-term effects were observed at 0.91 mg/L.

Additional information

Acute tests on all three trophic levels were performed to examine the aquatic toxicity of the substance. Aquatic invertebrates turned out to be the most sensitive species revealing an EC50 (48h) of 7.59 mg/L. Effects towards fish and algae were slightly higher providing a LC50 (96h) of 17.8 mg/L and an ErC50 (72h) of 19 mg/L, respectively.

Long-term toxicity tests were performed for all three trophic levels. Here, fish turned out to be the most sensitive species with a NOEC of 0.91 mg/L (mean measured, Danio rerio, OECD 215). Effects were observed for growth rate, while no effect on survival and toxic symptoms or abnormalities were observed. For the two other trophic levels, an ErC10 value for algae was determined to be 11.2 mg/L (based on growth rate; Desmodesmus subspicatus, OECD 201) and a NOEC for aquatic invertebrates at 2.5 mg/L (based on reproduction and mortality, Daphnia magna, OECD 211).
