The 72-h EC10 value is >100 mg/L as observed
in a Microbiological Inhibition Test.
The toxicity of 2-hydroxyethyl
acrylate to microorganisms of a domestic sewage treatment plant was
investigated according to ASTM´s "Microbiological Inhibition Testing
Procedure" (Roy F. Weston, Inc., 1996). Activated
sludge was incubated with nominal test substance concentrations of 0
(control), 0.1, 1.0, 5.0, 10, 15, 20, 100, 300, 500 and 800 mg/L. After
72 hours of exposure an EC10 > 100 mg/L was determined measuring the
