Bioaccumulation: aquatic/ sediment

According to REACH Regulation 1907/2006/EC, Annex IX section 9.3.2 column 2 a study for bioaccumulation in aquatic species, preferably fish need not be conducted if no direct or indirect exposure to the aquatic environment is expected.

At production sites, the ester is handled in closed systems for polymerisation. Diffuse releases into the environment from residual monomers in the polymeric products are not of concern due to the extremely low vapour pressure of the substances. Direct and indirect exposure of the test item to water is highly unlikely. Thus no test is required.

In the supporting study to 2-Propenoic acid, octadecyl ester the bioaccumulation potential of the test substance was calculated to be 323.6 L/kg or log BCF = 2.510 using the EPA Epiwin (v.4.11) software. According to Annex XIII a substance does not fulfil the Bioaccumulation criterion (B-) when the bio concentration factor (BCF) is lower than 2000, therefore a test for bioaccumulation: aquatic/sediment to 2-Propenoic acid, octadecyl ester does not need to be conducted.
