12.2 Persistence and degradability
2-Hydroxyethyl methacrylate, present at 100 mg/l, reached 92-100% of its theoretical BOD in 2 weeks using an activated sludge inoculum and the Japanese MITI test(1).
12.3 Bioaccumulative potential
An estimated BCF of 1.3 was calculated for 2-hydroxyethyl methacrylate(SRC), using a log Kow of 0.47(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low.
12.4 Mobility in soil
The Koc of 2-hydroxyethyl methacrylate is estimated as approximately 43(SRC), using a log Kow of 0.47(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-hydroxyethyl methacrylate is expected to have very high mobility in soil.

Other Information
Boiling Point cannot be experimentally determined: at 1013 hPa polymerization occurs at elevated temperatures, other boiling point: 67 C at 4.6 hPa.Methacrylates are normally stabilized by addition of phenolic inhibitors during transport and storage.An added stabilizer or inhibitor can influence the toxicological properties of this substance; consult an expert.May cause cross sensitization towards other acrylates.
