Abstract |
The photolysis of a series of aryl ketones on air-dried soil surfaces was examined to establish whether vapor transport has an effect on the rate and extent of photolysis. If vapor transport were significant on light-exposed soils, then differences in the observed photolysis rate profiles would be expected, with the compounds having higher vapor pressures exhibiting the greatest photolysis. The aryl ketones, including hexanophenone, dodecanophenone, octanophenone, hexadecanophenone, and octadecanophenone, had nearly identical photolysis rates in solution exposed to sunlamps (lambda max 310 nm). The results suggest that vaporization is not important for loss or transport of the compounds with vapor pressures less than 1.3 x 10(-3) torr on air-dried soils within the 15-d irradiation. |
