Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Sodium sulfate is not toxic to sediment dwelling animals, the lowest LC50 found for Hyalella azteca is 757 mg/l. Read-across from sodium sulfate to sodium hydrogensulfate is considered justified. Therefore it can be concluded that sodium hydrogensulfate is non toxic to sediment dwelling animals.
Key value for chemical safety assessment
Additional information
There were five publications found that were considered valid with restrictions. The lowest endpoint was found for Tricorythus sp., which was an experiment performed in river water (Goetsch and Palmer, 1997). The test species is a local organism from the southern part of Africa and Southeast Asia and is not a standard test species, therefore it is not considered representative for Europe and this endpoint is not used for the Risk Assessment.
Soucek and Kennedy (2005) performed tests with Hyalella azteca and Chironomus tentans. Davies and Hall (2007) and Soucek (2007) performed tests with Hyalella azteca. All tests were performed according to standard guidelines and had chemical monitoring. None of them were performed under GLP. Soucek and Kennedy (2005) found the lowest result for H. azteca, the LC50 found is 757 mg/l.
Sodium sulfate is not toxic to sediment dwelling animals.
Read-across from sodium sulfate to sodium hydrogensulfate is considered justified. Therefore it can be concluded that sodium hydrogensulfate is non toxic to sediment dwelling animals.
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.
