Additional information

Conclusion on classification

Available data: the acute and chronic data are as follows.

Fish acute data: 96h-LC50: > 98.2 mg/L (measured)

Daphnia Acute data: 48h-EC50: >100 mg/L (measured)

Algae growth inhibition data: 72h-ErC50 value (growth rate): >100 mg/L (measured); 72h No-Observed

Effect Concentration (NOEC): 100 mg/L (measured)

And the substance is not readily biodegradable, water solubility was 218 g/L at 20.0 °C, and logPow of the test substance at pH 5.0, 7.0 and 9.0 were all found to be <0.3.

Acute classification:

In according to Regulation (EC) 1272/2008, amendment 286/2011, table 4.1.0, the substance should be not classified 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 not be classified for Chronic (long-term) aquatic hazard.
