Phototransformation in air

Description of key information
No experimental data on the phototransformation of the substance in air are available. Based on estimation with the QSAR model AopWin (v1.92), in air the substance undergoes rapid degradation after reaction with hydroxyl radicals or ozone. The DT50-values after reaction with hydroxyl radicals are 2.21 hours and 2.13 hours for the Cis-isomer and Trans-isomer, respectively. The DT50-values after reaction with ozone radicals is 0.61 hours for both the Cis- and Trans-isomers. This indicates that the substance is not a long-range transported chemical in air according to the UNECE criteria (http://www.unece.org/fileadmin/DAM/env/documents/2000/ece/eb/ece%20eb%20air.60.e.pdf). These halflives will not be used for the CSA because these are calculated and not experimental values.
