Description of key information
According to ECHA guidance on information requirements and chemical safety assessment (v1.2, November 2012), Chapter r7b, Section 7.8.5, including Figure 7.8.4, if based on acute aquatic toxicity data neither fish nor invertebrates are shown to be substantially more sensitive, long term studies may be required on both. There are no indications from short term toxicity data that fish are substantially more sensitive than Daphnia. According to the integrated testing strategy, the chronic Daphnia study is to be conducted first. If based on the results of the chronic Daphnia test and the application of a relevant assessment factor no risks are observed (PEC/PNEC<1), no long term fish test may be conducted. A chronic Daphnia test result is available, and the results of the chemical risk assessment indicate no risk to the environment, thus the long term fish test is waived.

Additional information
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.
