Additional information

Environmental fate information related to transport and distribution was estimated with the PETRORISK tool. The log Koc values and Henry's Law constant (HLC) values were estimated based on the database included in the model. In addition, distribution to different environmental compartments was modelled with the tool.

The estimation of log Koc values and HLC values is based on individual compound structures, which are included in the CONCAWE Library. The overall range (all components) for the estimated log Koc values was from 1.83 to 5.20. The log Koc values of the representative individual structures that form the major part of the substance based on mass fraction (sum 0.7) are in the range 2.70 - 4.30.

The overall range for the estimated Henry's Law constant (HLC) values was from 0.00036 atm m³/mol to 8.416 atm m³/mol. The HLC values of the representative individual structures that form the major part of the substance based on mass fraction (sum 0.7) were in the range 0.521 atm m³/mol - 3.823 atm m³/mol.

According to the PETRORISK modelling results, major part of the emissions of the substance are distributed to air (ca. 97.6 %). Fractions distributed to other environmental compartments is expected to be low; water (1.7 %), sediment (0.45 %), soil (0.25 %).
