The log Kow of the xylene isomers and ethylbenzene ranges from 3.12 to
3.2 which suggests that they have the potential to sorb to soil and
sediment. A reliable adsorption/desorption study with xylene or one of
the other streams in this category as the test substance was not
identified. However, a study using o-xylene, conducted to a method
equivalent to OECD 121 using a HPLC method (Hodson et al 1988), gave an
estimated log Koc of 2.73 based on the measured K value.
Based on similar physico-chemical properties, this value is considered
appropriate for read across to all streams in this category.
The calculated Henrys Law constant is 623 Pa m³/mol. The
Henry's Law constants of the xylene isomers and ethylbenzene have been
calculated by a QSAR model and are supported by results from a
peer-reviewed handbook. The calculated value indicate that
volatilisation from water is expected to occur at a rapid rate.
