A relevant exposure of soil microorganisms is not expected.
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.
