Description of key information

A long-term toxicity test with Daphnia magna exposed to 2-hydroxyethyl methacrylate and conducted under GLPs, semi-static conditions, and following standard test guidelines (OECD 202, part 2), resulted in a NOEC for reproduction of 24.1 mg/L.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
24.1 mg/L

Additional information

One long-term freshwater aquatic invertebrate study was available for 2-hydroxyethyl methacrylate 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 for 21-days, under semi-static conditions, following OECD Test Guideline 202 (part 2), and under GLPs. The study concluded the 21-day NOEC for reproduction was 24.1 mg/L and was considered the key parameter for this endpoint.
