Description of key information
Very toxic (acute effect) to aquatic algae and cyanobacteria.
Very toxic to aquatic algae and cyanobacteria based on long-term (chronic) toxicity study data.
Key value for chemical safety assessment
Additional information
The toxicity to aquatic algae and cyanobacteria was assessed in a study conducted according to OECD guideline 201 under consideration of GLP and the OECD 23 guidance document for difficult substances. The test was conducted as static test with 0.625 - 1.25 - 2.50 - 5.00 - 10.0 % of the saturated solution. The compound is strongly adsorbing therefore, the effects after an exposure time of 72h were based on the initial measured test concentrations. The ErC 50 was determined to be 0.0303 mg/L and the ErC10 was determined to be 0.0230 mg/L.
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.
