The xylene isomers and ethylbenzene are expected to degrade by indirect
photolysis in air, predominantly through reaction with hydroxyl
radicals. Using rate constants recommended by Atkinson (1985) and the
concentration of hydroxyl radicals recommended in the ECHA guidance
(2010), half lives of around 1 -2 days are calculated for each of the
xylene isomers and ethylbenzene. These data indicate that indirect
photolysis is expected to be a significant route of removal from the
