Description of key information
No reliable data on magnesium sulphate itself are present. Several supporting studies show LC50s from 24 -96 hr of > 10000 mg/L. A key study on potassium sulphate and potassium magnesium sulphate is available. As for the potassium magnesium sulphate no effect has been found at the highest dose tested (63.3 mg/L) and the sulphate contains a double salt, the study with potassium sulphate is a key study. The static study was performed according to EPA test guidelines with fathead minnow fish and a 96hr LC50 of 680 mg/L was determined. Although fish were fed once during the study it is not expected that this will affect the result. Analytical monitoring was performed.
