Additional information
Due to the low solubility and complex nature of the test item, media for investigations of short-term aquatic toxicity were prepared as a Water Accommodated Fractions (WAFs). Given that the toxicity cannot be attributed to a single component or a mixture of components, but to the test item as a whole, results were based on nominal loading rate.
Conclusion on classification
The test item is classified as Aquatic Acute 1 because the LL50 value determined for algal growth rate was < 1 mg/L. Since long-term toxicity data are available for only one trophic level (algae), experimental results should be assessed in terms of substances for which adequate chronic toxicity data are available and substances for which adequate chronic toxicity data are not available. The most stringent classification outcome is then applied. Based on the EL50 value of 0.51 mg/L determined for algal growth rate, classification as Aquatic Chronic 1 is applicable when the result is compared to criteria given by Regulation (EC) No 1272/2008 (2nd ATP; 10 March 2011) for non-rapidly biodegradable substances for which adequate toxicity data are not available.
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).
