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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
NOEC (Multiday) respiration inhibition: 5000-8000 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 5 000 mg/L
Additional information
Sodium chloride in waste water treatment plant is well investigated as waste water treatement plant based on the sea shore may use sea water to flush the system. Sodium chloride can stimulate growth in pure cultures up to concentrations of 300 -600 mg/L. Activated sludge in simulated sewage treatment plants have a high tolerance for sodium chloride in waste water. While the available data gives wide ranges for the NOEC concentration in simulated sewage treatment plants, no data has been identified from experiments comparable to the standard activated sludge inhibition protocol. In the absence of such data, the lower end of the reported multi day expoure NOEC for BOD performance (i.e. respiration inhibition) after intermittent dosing of sodium chloride is used as key value.
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.
