Additional information

Where possible, PNEC calculations have been undertaken using default assessment factors in accordance with ECHA guidance on information requirements and chemical safety assessment Chapter R.10: Characterisation of dose [concentration] response for environment.

Conclusion on classification

Overview of Results used for Classification and Labelling:

Fish, short-term, freshwater: LC50 = 299 mg/L; Chronic, freshwater; NOEC = 18.5 mg/L

Daphnia magna, short-term, freshwater: LC50 = 154 mg/L: Chronic, freshwater: NOECD = 20.5 mg/L

Algae, freshwater: EC50 = >72.6 mg/L, NOEC = 72.6 mg/L

Classification for environmental effects is not justified based on the lack of toxicity in acute tests in three aquatic aquatic compartments and low toxicity in long-term tests in two aquatic compartments. While the substance is not readily biodegradable there is evidence that ultimate degradation may occur.
