Additional information

Since 2-dimethylaminoethyl methacrylate is readily biodegradable an indirect exposure to soil via sewage sludge transfer is unlikely. In addition, no direct releases to soil from point sources are known; therefore, significant exposure of terrestrial compartments is not expected. At production sites methacrylates are handled in closed systems for polymerisation. Diffuse releases into the environment may occur from residual monomers in the polymeric products. Most of 2-dimethylaminoethyl methacrylate is industrially converted to the quaternary ammonium salt and polymerized for flocculent use in water treatment. This chemical is also used as a component monomer of copolymers in die polymer industry, and die products are used for paper agents, coatings and others.

Furthermore, the physical and chemical properties of 2-dimethylaminoethyl methacrylate demonstrate a low potential for adsorption (log Koc = 1.29) and bioaccumulation (log Pow = 1.13), respectively.

In conclusion, based on such low exposure levels studies on terrestrial organisms are not required. Thus, risk assessment will be based on EPM.
