Conclusion on classification
In accordance with the CLP Regulation, No 1272/2008, the classification for acute aquatic hazard apply where the 96 hr LC50 (fish) and/or 48 hr EC50 (daphnia) and/or 72 hr ErC50 (algae) are less than or equal to 1 mg/L. The test item was determined to have a LC50 and ErC50 greater than 100 mg/L for fish and algae, respectively, and an EC50 of 41.0 mg/L for daphnia. As such, the classification criteria has not been met.
In accordance with thje CLP Regulation, No 1272/2008, where there are adequate chronic toxicity data for 1 or 2 trophic levels, both the following should be assessed:
- according to the criteria for long-term aquatic hazard where adequate chronic data are available. A classification is applicable where the chronic NOEC is less than or equal to 1 mg/L, and
- (if for the other trophic level(s) adequate acute toxicity data are available) according to the criteria for long-term aquatic hazard where adequate chronic toxicity data are not available. A classification is applicable where the 96 hr LC50 (fish) and/or 48 hr EC50 (daphnia) and/or 72 hr ErC50 (algae) is less than or equal to 100 mg/L.
Long-term data is available for daphnia and algae, with the chronic NOEC determined to be 3.2 mg/L and 10 mg/L, respectively. The LC50 for fish is greater than or equal to 100 mg/L. Therefore, based on the acute and chronic data, the test item does not meet thej criteria for classification.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
