Additional information
Due to the complex nature of the test item, the test 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 not classified for short-term toxicity to the environment under the criteria given by Regulation (EC) No 1272/2008 (2nd ATP; 10 March 2011)because the lowest EL50 value from short-term testing of three trophic levels (22 mg/L loading rate WAF determined for algae) was > 1 mg/L.
The test item is not classified for long-term toxicity to the environment under the criteria given by Regulation (EC) No 1272/2008 (2nd ATP; 10 March 2011) because the substance is rapidly degradable and the lowest No Effect Loading Rate (NOELR) value from long-term testing of three trophic levels (4.5 mg/L loading rate WAF determined for algae) was > 1 mg/L.
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).
