48-hr-acute toxicity of m-Xylylenebismaleimide to Daphnia magna was
studied under semi-static conditions according to OECD Guideline 202
(2004). Daphnids were exposed to control and test chemical at
concentrations of 0.221, 0.322, 0.446, 1.19, 3.60 mg test item /L (geom.

Pseudokirchneriella subcapitata after 72 hours. The EC50-value with 95%
confidence intervals (ErC50) after 72 h was 1.09 mg/L (1.04 - 1.11). The
EC10-value with 95% confidence intervals ErC10 after 72 h was 0.722 mg/L

most sensitive organism to m-Xylylenebismaleimide. The EC50 value
determined during a 48h short-term toxicity study under semi-static
conditions was 0.415 mg/L.
