Data is available on the acute toxicity of calcium sulfate to invertebrates. No short-term toxicity was observed at the concentrations tested.
guideline study was performed which assessed the acute toxicity of
calcium sulfate dihydrate (NIER, 2003) to Daphnia magna in a
limit test. The 48 h LC50 for calcium sulfate dihydrate was found to be
>100 mg/L, which is equivalent to >79 mg/L for calcium sulfate
anhydrous. No mortalities or adverse effects were noted at this
A further OECD guideline study (van Eijk, 2009), investigated the
toxicity of flue gas desulphurisation gypsum on Daphnia
A literature study is available that quotes the 48 h LC50 values for
calcium sulfate as >1970 mg/L for Daphnia magna and >1910 mg/L
dubia (Mount et al, 1997).
weight of evidence approach, the acute toxicity of calcium sulfate to
invertebrates is generally greater than the highest concentration tested
and is considered to be greater than the maximum solubility of
calcium sulfate in water.
Calcium sulfate showed no short-term toxicity to aquatic invertebrates
and is therefore not acutely toxic to invertebrates at the limit of its
