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, the substance need not be classified regarding toxicity to the environment.

Although the substance is not regarded as being readily biodegradable, classification is not justified based on the low toxicity observed in acute studies at three trophic levels, and low potential for bioaccumulation.

Overview of Results used for Classification and Labelling:

Fish, short-term, freshwater: LC50 ca 359 mg/L, NOEC 311 mg/L

Daphnia magna, short-term, freshwater: LC50 > 100 mg/L, NOEC 100 mg/L

Algae, freshwater: EC50 = > 100 mg/L, NOEC 66.7 mg/L (100 mg/L pH adjusted)
