2-[2-(2-ethoxyethoxy)ethoxy]ethyl methacrylate

Short-term toxicity to aquatic invertebrates

Description of key information

There are no short-term data available for aquatic invertebrates with Ethyltriglycol methacrylate but there is a long-term toxicity study to daphnia 
(21-day study, semi-static conditions according to OECD 211, Klimisch score 1, Evonik Industries 2012). In this vaild long-term guideline study for aquatic invertebrates (daphnids) Ethyltriglycol methacrylate has a NOEC of 100 mg/L (21-day, daphnia magna) based on mortality of adult daphnids. Therefore the short-term toxicity to daphnids EC50 (48 h) for Ethyltriglycol methacrylate is expected to be greater than 100 mg/L (based on mortality). For this reason there is no reason to perform a short-term toxicity test on aquatic invertebrates.

Additional information

There are no short-term data available for aquatic invertebrates with Ethyltriglycol methacrylate but the mortality data of the adult daphnia in the long-term toxicity study under semi-static conditions according to OECD 211 indicate that up to 100 mg/L there is no immobilisation of daphnia within 48 h, but also within 21 d (Klimisch score 1, Ibacon 2012). In this vaild long-term guideline study for aquatic invertebrates (daphnids) Ethyltriglycol methacrylate has a NOEC of 100 mg/L (21-day, daphnia magna) based on mortality of adult daphnids. Therefore the short-term toxicity to daphnids EC50 (48 h) for Ethyltriglycol methacrylate is expected to be greater than 100 mg/L (based on mortality). For this reason there is no reason to perform a short-term toxicity test on aquatic invertebrates.
