Description of key information

DTO is a UVCB substance and it is therefore appropriate for the purposes of assessing environmental fate to consider volatilisation of the constituents rather than whole substance.


The Henry’s Law constant (HLC) describes the potential for volatilisation from water. No measured values are available, hence the HLC can be estimated, e.g. from the values of vapour pressure and water solubility. Calculated HLC values for the constituent blocks of DTO are in Table 1.9.
