LC50 (48 h) > 113 mg/L for Daphnia magna (according to OECD 202)

Key value for chemical safety assessment

Additional information

The acute toxicity of 2 -isocyanatoethyl methacrylate (MOI) to invertebrates was tested in a study conducted by Showa Denko (2013), using daphnids (Daphnia magna) as test species. This static dose-response test was carried out according to the OECD-Guideline 202 under GLP-conditions over a period of 48 h. The nominal test concentrations used were 0, 6.25, 12.5, 25.0, 50.0 and 100 mg/L corresponding to mean measured concentrations of 0, 6.56, 13.0, 25.3, 52.4 and 113 mg/L. The resulting LC50 was >113 mg/L (geometric mean measured).
