Additional information
The following data were obtained for Similar Substance 1. It is expected that the Target substance will present similar effect levels to aquatic plants. Justification for Read Across is given in Section 13 of IUCLID.
A GLP guideline study according OECD 221 has been conducted. After 7 d of semi-static exposure the growth rate inhibition and the inhibition of yield was determined. The ErC10 was determined to be 12.5 mg/L based on frond number and the ErC50 was determined to be > 200 mg/L. Therefore, the test item is not acutely harmful to aquatic 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.
