Conclusion on classification
Figure 4.1.1. "Catergories for substances long term hazardous for the aquatic environment" details the procedure for classifying a material when there are adequate chronic toxicity data available for 1 trophic level. Based on the results of the 72h algae study the NOEC has been established as 1.2 mg/l, which in comparison with table 4.1.0 (b)(i) indicates that the substance should not be classified as Chronic Category 2. The results of the 48 hr daphnia study (EC50 = 32 mg/l) in conjunction with the substances lack of rapid degradability indicate that the substance should be classified as Category Chronic 3 - H412 Harmful to aquatic life with long lasting effects.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
