Key value for chemical safety assessment
Additional information
Acute toxicity to aquatic algae was assessed in a 72 -hour study under static exposure conditons, following OECD guideline 201.
In a preliminary test at concentrations between 1 and 100 mg/l, low toxicity, in terms of inhibition of growth rate and yield, was seen. Based on such results, main test was run as limit test at concentration of 100 mg/l. Controls were run and were valid. Analytical monitoring demonstrated that test substance solution were stable under the testing period, thus effect levels were referred as nominal concentrations. Effect levels at 72 after start of the study were determined.
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.
