Additional information

Conclusion on classification

Based on the available studies for the short-term aquatic toxicity, the lowest LC50/EC50 value is 0.3 mg/L. The substance is considered as not readily biodegradable and the partition coefficient was determined to be greater than 4.

Therefore, the substance is classified as Hazardous to the aquatic environment, Acute category 1 and Chronic category 1.

Acute M-factor =1
