Aquatic
LC50Fish > 1970 mg/l, 96 hoursFathead minnow (Pimephales promelas)
Persistence and degradability
Not applicable for the salt of inorganic compounds. Calcium sulfate dissolves in water without
undergoing chemical degradation.
Bioaccumulative potential
Bioaccumulation is not expected.
Mobility in soil
Calcium sulfate has a low potential for adsorption to soil. If water is applied, gypsum dissolves and
the calcium and sulfate ions are mobile and penetrate the subsoil (7).
Other adverse effects
None expected.
