Acutely harmful to aquatic invertebrates.
To determine the toxicity of morpholine to aquatic invertebrates, a study following OECD 202 using Daphnia magna was performed according to GLP. The test animals were exposed under semi-static conditions Based on nominal, analytically verified test concentrations a 48-h EC50 of 45 mg/L was determined (NITE, 1997). This value was selected as key data.
In conclusion, morpholine is assessed to be acutely harmful to aquatic invertebrates.
