Conclusion on classification

Acute data:

Algae, OECD201: 72-hour ErC50: >0.217mg/L (measured)

Daphnia, OECD202: 48-hour EC50: 0.954 mg/L (measured)

Fish, OECD203: 96-hour LC50: 3.724 mg/L (zebra fish); 1.50 mg/L (Medaka) (measured)

 

Long-term data:

Algae, OECD201: 72-h NOEC: 0.0874 mg/L (measured).

Daphnia, OECD211: 21-day NOEC: 0.023 mg/L (measured)

And the substance is not readily biodegradable, water solubility was 7.26 mg/L at 20.0 °C, log Pow at 25 °C, was 4.3.

 

Acute classification:

In according to Regulation (EC) 1272/2008, amendment 286/2011, table 4.1.0, the substance should be classified as category 1 for Acute (short-term) aquatic hazard.

 

Chronic classification:

In according to Regulation (EC) 1272/2008, amendment 286/2011, table 4.1.0, the substance should be classified as category 1 for Chronic (long-term) aquatic hazard.
