Additional information

Acute toxicity of 2 -isocyanatoethyl methacrylate to aquatic organisms was investigated for different trophic levels (fish, invertebrates and algae).

The test conducted with fish (Pimephales promelas) resulted in an LC50 -value of 162 mg/L (nominal) after 96 h. The aquatic toxicity of the test substance on invertebrates has been evaluated on an acute study on daphnids (Daphnia magna) resulting in an EC50 (48 h) of > 113 mg/L (geometric mean measured). For algae (Pseudokirchneriella subcapitata) an ErC50 (72 h) of > 97.4 mg/L (geometric mean measured) and a NOErC of 97.4 mg/L (geometric mean measured) is reported based on growth rate.
