The 48-hr-acute toxicity of
trimethylolpropane to Daphnia magna was studied under static conditions.
Daphnids were exposed to the substance at nominal concentrations of
5,000; 7,500; 10,000; 15,000, 20,000, 25,000; 40,0000 mg/L.
Immobilization was observed at 24 and 48h. The 48-hour EC50 was 13,000
mg/L (based on nominal concentrations).
This study is classified as acceptable and
satisfies the guideline requirements for an acute toxicity study with
Reference: Walton, J.R. and Davis, E.M., 1980
Assessment is by read-across to the source substance trimethylolpropane
(CAS No: 77-99-6).
