Description of key information

No reliable study on magnesium sulphate is present. Based on a reliable 48-hours study with daphnia magna performed on potassium sulphate the LC50 is determined to be 720 mg/l.

Additional information

No reliable data on magnesium sulphate itself are present. A supporting study shows LC50s of 24 hr of > 1000 mg/L. A key study on potassium sulphate is available. The static study was performed according to EPA test guidelines with daphnia magna exposed to 500, 1000, 1250, 1500, 2000, 2500, 5000, and 10000 mg/L (nominal concentrations) and a 48hr LC50 of 720 mg/L was determined. Analytical monitoring was performed.
