Additional information
No analytical monitoring was done in tests on fish and daphnia. However, no evidence of precipitation was reported.
Analytical monitoring was carried out only in the test on lemna. OECD medium was used instead of 20AAXP medium, as test item precipitated from the 20AAXP medium in 24 hours, even upon filtration. As test substance was not stable for 3 days in OECD medium, the test was run as semistatic, with renewals on day 3 and 5. Final results were derived from measured concentrations. Results were only based on frond numbers as dry weigth could not be assessed due to the substance deposition on roots and/or leaves of plants.
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.
