Additional information

Conclusion on classification

Acute aquatic data are available for three trophic levels for the test item and read-across substances. No effects were seen in any of the tests at up to 100 mg/L. The test item achieved biodegradation of 36 % after 28 days and therefore is considered to be not readily biodegradable. Since the effect value is > 100 mg/L, the test item does not need to be classified for acute aquatic hazard.

 

Chronic toxicity data are only available for algae for the test item. Based on a NOELR of 25 mg/L, the substance does not need to be classified for chronic aquatic toxicity.

However, as chronic toxicity data are only available for one trophic level, acute toxicity together with environmental fate data are also assessed. The test item is considered to be not readily biodegradable. The short-term EC50/LC50 values are > 100 mg/L, therefore the test item is not considered as hazardous to aquatic environment with long-lasting effects and no classification for chronic toxicity is required.
