Description of key information
Additional information
In water isobutyl methacrylate (i-BMA) will be rapidly biodegraded, abiotic degradation by hydrolysis is not of major concern. From the water surface the test substance will evaporate moderately into the air. After exposure to the air, i-BMA will be rapidly degraded by photochemical processes (half life 16.97 h). Based on a logPow of 2.95, bioaccumulation of i-BMA is not expected. The adsorption rate constants (Koc) of i-BMA in soil was measured in three soil types, resulting in an average Koc value of 2767 l/kg indicating a high adsorption potential of i-BMA to the solid soil phase. Furthermore, based on a Mackay Level 1 calculation the substance will mainly partition to air (ca. 95.1 %) in this equilibrium model. In the Mackay Level III model, which additionally takes into account transport and degradation processes i-BMA, when released to air or water, will predominantly remain in the environmental compartment into which it was released (air: 95.8 %; water: 97.5 %).
