^aSamples of 653 μM of pLPC in 6 mL acetonitrile contained within fused-silica test tubes were used for all experiments.

^b(N) Oxygen removed from samples by sparging with argon for 30 minutes. (Y) samples irradiated without sparging.

^cConcentrations in μM determined by GC-MS reported as mean ± 95% confidence interval for four or more experiments. A Q-test with 99% confidence was performed to remove outlying data due to gross errors.

^dSamples Contains 1.0 mM of DBTO.

^esample irradiated with eight broadly emitting fluorescent bulbs centered at 350 nm for five hours.

^fOzone gas gently passed through sample for 10 minutes.

^gAir gently passed through sample for 10 minutes.

^hnot detected.
