In a study conducted according to OECD Guideline 106 (Prelininary Tests) soil sorption coefficients (Koc) from 96230 (log Koc= 4.98) to 3009119 (log Koc=6.48 ), depending on the soil type, were obtained. Based on these results and taking into account the classification of Blume & Ahlsdorf (1993), a very high sorption of Bis(2-ethylhexyl) carbonate onto soil organic matter is to be expected.

Henry's Law Constant of Bis(2-ethylhexyl) carbonate was calculated using EPIWIN v3.20, HENRYWIN v3.10 (bond method). The calculation yielded a very high value: H=0.0328 atm x m³/mole corresponding to H=3322.6 Pa x m³/mole at 25°C. This result indicates that Bis(2-ethylhexyl) carbonate would be highly volatile from aqueous solution. Due to missing information about the applicability of the calculation model in respect to the substance under investigation the results should be treated with care.

Taking into account a high Henry's Law constant the derivates will migrate in the gas phase of the atmosphere in appreciable amounts, therefore this elimination path will be of high importance.
