Description of key information

Sodium sulfate is not toxic to sediment dwelling animals, the lowest LC50 found for Hyalella azteca is 757 mg/L.

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.
