Description of key information

Based on the low calculated log Pow value (log Pow= 1.23, Evonik Industries, 2012) for methacrylic anhydride a bioaccumulation rate of 2.2 was estimated according to the formula of Veith et al. 1979 (Guidance R.7C). A low bioaccumulation potential with a BCF of 3.0 L/kg has been estimated with EPIWIN, 2012, program BCFBAF (Evonik Industries, 2012).
