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.

PNECs were derived from the study with the most sensitive species available for each compartment/endpoint.

Conclusion on classification

Acute toxicity:

Based on the results obtained in the aquatic toxicity studies, together with teh consideration that the substance is not regarded as being readily biodegradable, classification regarding toxicity to the environment should be considered.

Overview of Results used for Classification and Labelling:

Fish, short-term, freshwater: LC50 9.26 mg/L

Daphnia magna, short-term, freshwater: LC50 > 120 mg/L

Algae, freshwater: EC50 = 71.7 mg/L
