Description of key information

A short-term toxicity limit test with Daphnia magna exposed to methacrylic acid, monoester with propane-1,2-diol and conducted under GLPs, semi-static conditions, and following standard test guidelines (OECD 202), resulted in 48-hour LC50 value of >143 mg/L, the measured limit concentration tested.

Additional information

One freshwater aquatic invertebrate study was available for methacrylic acid, monoester with propane-1,2-diol and considered reliable for assessment of this endpoint. The study was conducted with Daphnia magna and found to be of good quality and assigned a Klimisch score of one. The study was conducted as a limit test for 48-hours, under semi-static conditions, following OECD Test Guideline 202, and under GLPs. The study concluded the 48-hour EC50 value was >143 mg/L, the measured limit concentration tested and was considered the key parameter for this endpoint.
