Description of key information

Sodium sulfate is not toxic to fish. The study according to EPA guideline with Pimephales promelas gave an LC50 value of 7960 mg/L.

Key value for chemical safety assessment

LC50 for freshwater fish:
7 960 mg/L

Additional information

Many publications are available on short-term toxicity of sodium sulfate to fish, but most were not found reliable. Only one study was reliable with restrictions, Mount et al. (1997). The study was performed according to EPA guideline and with determination of test substance concentrations (ion-chromatography).

It was not performed under GLP. Pimephales promelas was exposed to a range of sodium sulfate concentrations in reconstituted water. The critical confounding factors pH and oxygen were within acceptable ranges. The acute toxicity for fish is very low, with LC50values far above 1000 mg/L.
