Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC50 (120 h, cell number, Nitzschia linearis) = 2430 mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 2 430 mg/L
Additional information
Three studies are available from published literature on acute toxicity of sodium chloride to algae and cyanobacteria. One additional study (Setter 1982) looks at mechanisms of toxicity from changing sodium chloride concentration in the media (i.e. uses pre-adapted cultures).
The diatom Nitzschia linearis was found most sensitive with an EC50 (120 h, cell number) of 2430 mg/L. Unfortunately, the article does not provide sufficient information to conclude on a No Observed Effect Concentration for Nitzschia linearis.
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.
