Description of key information
Additional information
A Rate constant (for indirect photolysis) of 0.0000000000065 cm³/(molecule*sec) is reported for cumene resulting in a DT50 of 59 hours.
Data on the phototransformation in water of cumene is presented in the EU-RAR (2001) in section 3.1.1.2.1. Cumene is reported to have a DT50 of 0.4-5.1 h by Mill et al. (1980). For the chemical safety assessment the worst case DT50 of 5.1 h will be used.
No experimental data on photo-degradation and hydrolysis of cumene are presented in the EU-RAR (2001) and no more recent experimental data for these endpoints could be identified.
Hydrolysis of cumene is not expected to occur due to the lack of hydrolyzable functional groups.The test substance is regarded as readily biodegradable. Therefore, the performance of an experimental study on hydrolysis is unjustified. Cumene is expected to biodegrade in soil and may volatilize from the soil surface. Therefore, phototransformation in soil is expected to be of no or minor relevance for the fate of cumene in the terrestrial environment and the performance of an experimental study on photodegradation in soil is unjustified.
