Description of key information

Acute toxicity on Daphia magna reveals an EC50 > 120 mg/L.

Key value for chemical safety assessment

Additional information

In a 48-hour acute toxicity study, neonate Daphnia magna were exposed to 5-Methyl-3- vinyloxazolidin-2-on at nominal concentrations of 0 (control) and 120 mg/L under static conditions in accordance with the OECD 202 guideline. The water pH, temperature and dissolved oxygen were within acceptable guideline specifications. Immobilization (mortality) and sublethal effects were observed daily. The 48 hour EC50 values determined in this acute toxicity study were >120 mg/L based on the nominal concentration of the test substance.
