Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
The purpose of the study is to evaluate the test substance for its ability to generate toxic effects in Pseudokirchneriella subcapitata during an exposure period of at least 48 and at most 96 hours and, if possible, to determine the NOEC, EC10 and EC50 for both inhibition of growth rate and inhibition of yield.
Key value for chemical safety assessment
Additional information
Due to the very low solubility of this substance in test medium, concentration levels that might be toxic for algae could not be reached.
The EC50for both growth rate inhibition (72h-ERC50) and yield inhibition (72h-EYC50) was above the solubility limit of A4N3 in test medium.
The 72h-NOEC for both growth rate inhibition and yield inhibition was at the solubility limit of the substance in test medium.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).
