Any other information on results incl. tables
14C-PBO was found to rapidly photolyze in an aqueous buffer at pH 7 and 25 °C
when exposed to natural sunlight. Within 36 hours of exposure to sunlight less
than 10 % of the total radioactivity in the exposed sample was 14C-PBO.
The calculated t1/2 of the aqueous photolysis rate of PBO was 8.4 hours of
sunlight and the photolysis of PBO followed first order kinetic. Two major
degradates were observed at concentrations greater than 10 % of the total
radioactivity. One degradate was identified as an alcohol degradate of PBO,
the other was identified as the corresponding aldehyde of the alcohol degradate.
Applicant's summary and conclusion
- Conclusions:
- The substance was found to rapidly photolyze in an aqueous buffer at pH 7 and 25 °C when exposed to natural sunlight.
DT50 = 8.4 hours at pH 7
