Description of key information

Additional information

Tests on three trophic levels are available either with the test substance or an analogue (Chemservice 2010a, Harlan 2013e, Harlan 2013f). All tests indicate that at a loading rate of 100 mg/L, no toxicity is observed at the maximum attainable concentration. In a daphnia reproduction study (Envigo 2016) performed on a close analogue substance no toxicity was observed at a loading rate of 100 mg/L (measured concentrations were below the LOQ (0.021 mg/L).

Therefore the starting point for risk assessment will be the water solubility limit of 0.2 mg/L.

Based on a test on respiration of activated sludge with an analogue of the test substance, no toxicity to micro-organisms is expected at 100 mg/L (Chemservice 2010b), which will be used a NOEC for risk assessment.
