Description of key information
A relevant exposure of soil microorganisms is not expected.
Key value for chemical safety assessment
Additional information
In order to assess the effects of methyl methacrylate on terrestrial organisms, a test on the respiration inhibition of natural soil micro-flora is available. After two days incubation it appeared to be a dose-related inhibition of respiration. But at the end of an exposure duration of 28 days even for the highest concentration of 1,000 mg/kg this effect was no longer significant. Furthermore, the substance shows a low adsorptive (log Koc = 0.94 – 1.86) as well as a bioaccumulative (log Pow = 1.38) potential.
In conclusion, a relevant distribution into soil and a considerable exposure of soil microorganisms is not expected. Methyl methacrylate is not toxic to soil microorganisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
