Key value for chemical safety assessment

Additional information

Overall QSARs estimated half-life for degradation of TCPP in air based upon AOPWIN Model is 5.734 hours.

Based on the data on photochemical degradation of TCPP in the air, it is considered to rapidly degrade in the atmosphere via photooxidation process.

The following information is taken into account for any hazard / risk / persistency assessment:

AOPWINProgram, v.1.92 estimated data:

Reaction with hydroxyl radicals at 25oC:

Overall OH Rate Constant: =44.7631 x 10-12cm3/molecule-sec

Half Life: =0.239 days, 2.867 hours (12-hour day; 1.5x106OH/cm3)
