According to Annex IX column 2 of REGULATION (EC) No 1907/2006,
terrestrial toxicity studies do not need to be conducted if direct and
indirect exposure of the soil compartment is unlikely.The substance is
not expected to partition into the terrestrial environment according to
the CSR which determined almost exclusive partitioning to the aquatic
environment under several scenarios. Environmental monitoring data from
the Perstorp production facilities did not detect any monomers in any
soil and sediment samples. The measured Log Kow of 0.32 and the
classification of the substance as readily biodegradable in the aquatic
environment, provide further validation that exposure to soil
macroorganisms is not expected.
