Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
With high probability acutely not harmful to algae, no toxic effects occur in the range of water solubility.
Key value for chemical safety assessment
Additional information
The inhibiting abilities of Perylen Schwarz/Black I to Pseudokirchnerella subcapitata were examined in a GLP study according to OECD guideline 201.
After 72 h the EC50 value for Perylen Schwarz/Black I was determined to be > 100 mg/L based on the nominal concentration of the test substance (BASF AG 2006).
No effect was observed up to the solubility limit of the test substance in water.
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.
