Additional information

The determined Koc value of 12589 indicates that the substance will have a moderate potential to adsorb to sediment/soil (ECHA guidance 7c, 2012).

To assess the volatilisation potential of the substance a Henry's law constant was calculated which showed a value of 11.3 Pa. m3/mol at 12°C. Distribution modelling showed that some volatilisation will occur. 

Based on Level III distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 54464-57-2 and the measured physico-chemical parameters as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (89.1%) with smaller amounts to water (8.84%) and sediment (2.08%) and a negligible amount to air (0.02%).

The SimpleTreat model, which is incorporated in EUSES, simulated the distribution of the substance in a Sewage Treatment Plant based on vapour pressure, water solubility, log Kow and biodegradability. The model predicts that 0% of the substance will biodegrade, 37.2% of the substance will partition to water, 56.8% to sewage sludge and 6.03% to air at 12°C. Experimental data show that the removal from the STP ranges from >50% to far more than 90%.
