Additional information

Short term tests with species of 3 trophic levels are available. Algae turned out to be the most sensitive species revealing an EC50 (72h) of 32 mg/L. Short term effects of the substance towards fish and daphnia were found in the same range providing a LC50 (96h) of 70 mg/L and an EC50 (48h) of 86 mg/L, respectively.

In a short respiration test a 30 -min EC20 of 35 mg/L was determined. The results for a Pseudomonas putida test were 30 min EC10 of 57 mg/L.

Thus, the test substance is acutely harmful to aquatic organisms. Depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible.
