For the assessment of aquatic toxicity information on all three trophic
levels are available. Acute toxicity to fish was determined in three
different studies. The most sensitive species was Oryzias latipes showing
a LC50 of 19.1 mg/L after 96 h in a semi-static test system. The MOE
Japan reported a EC50 (48h) of 33 mg/L to Daphnia magna using a
semi-static test system according to OECD guideline 202. In a second
study a EC50 (48 h) of 53 mg/L was measured using the same species. In a
OECD Guideline 201 study the growth inhibitory effects of
2-dimethylaminoethyl methacrylate on Scenedesmus subspicatus was
determined as ErC50 = 69.7 mg/L.
No studies on long-term toxicity to fish are available. However, the
hazard assessment of 2-dimethylaminoethyl methacrylate reveals neither a
need to classify the substanceas
dangerous to the environment, nor is it a PBT or vPvB substance,
nor are there any further indications that the substance may be
hazardous to the environment. Therefore, and for reasons of animal
welfare, a long-term toxicity study in fish is not provided. The
long-term toxicity to aquatic invertebrates was assessed according to
OECD Guideline 211. After 21 days of exposure a NOEC of 4.35 mg/L was
For the determination of toxicity to microorganisms the results of two
studies of the structural analogues 2-dimethylaminoethyl acrylate
(CAS# 2439-35-2) was used. The toxicity of this substance on
microorganisms was determined in two different studies using Pseudomonas
putida (EC10 = 210 mg/L) and activated sludge from industrial sewage
treatment plant (EC20 > 1000 mg/L), respectively.
