Additional information
OECD guideline 221.
In the preliminary test, nominal concentration were: 0, 10, 100 and 500 mg/l. Concentrations were determined by photometry at day 0 and day 7 and resulted to be stable. Therefore, static conditions were used for the test.
Definitive test was run as limit test, as no significant toxic effects were noted in the preliminary test. Effect levels were assessed based on nominal concentrations as measured concentrations were within the 80 - 120 % range of nominal ones.
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.
