Additional information

Conclusion on classification

Classification related key information

Biodegradation in water: screening tests: not readily biodegradable

The partition coefficient (n-octanol/water) log Pow is > 3. 78.

Acute toxicity

-         to fish: LC50 (96 h) >1000 mg/L

-         to aquatic invertebrates: LC50 (48 h) >1000 mg/L for Daphnia

-         to aquatic algae: EC50 (96 h) =354.67 mg/L

Chronic toxicity not available

Classification according to CLP

Based on the data above, UV-1084 is considered to be not rapidly degradable. The acute aquatic toxicity L(E)C50 values are >1000 mg/L for fish and aquatic invertebrates and 354.67 mg/L for algae. No chronic data are available. Therefore, according to Regulation (EC) No. 1272/2008 (CLP), no aquatic toxicity classification is taken.
