Adsorption / desorption

The Koc of diethyl succinate was estimated to be 21.2 L/Kg, using the EPA OPERA (Q)SAR model.

Henry's Law constant

The Henry’s Law Constant of diethyl succinate was determined to be HLC = 4.6E-6 atm•m3/mole, equivalent to 0.47 Pa•m3/mole, using the EPA OPERA (Q)SAR model.

Distribution modelling

Distribution in environmental compartments has been calculated using a Fugacity model, under the emission scenario of 1000 kg/h into each of air, water and soil compartments, according to Mackay, Level III. Distribution in various environmental compartments is estimated as: Air= 4.73%; Water= 34.2%; Soil= 61% and Sediment= 0.0929%.

The soil was then found to be the major target compartment.
