Additional information

The adsorption rate of i-BMA to soil was measured in three types of soil. The calculated value of 2767 l/kg indicates a high adsorption potential of i-BMA to the solid soil phase. However, the study failed establish an adsorption plateau and used non-sterilised soil and therefore rapid biodegradation by soil microflora may have contributed to the disappearance of iBMA from the aqueous phase and the true Koc is likely to be lower than that assumed.

Based on the calculated Henry´s Law constant (63.9 Pa*m3/mol at 25°C) i-BMA will evaporate moderately from the water surface. In addition, based on a Mackay Level 1 calculation the substance will mainly partition to air (ca. 97.2 %) 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 %).
