Abstract
Plant uptake rate constants (k sub 1) were determined for vapor-phase 2,3,7,8-TCDD using grass, azalea, spruce, kale and pepper foliage, and the fruit from apple, tomato and pepper. Plants were exposed to vapor-phase (supra 3H-)2,3,7,8-TCDD for 96 h, and the TCDD sorption rate constant for each plant species was determined from measured air and plant concentration. Sorption rate constants for the different plant tissues, expressed on a fresh weight basis, varied by two orders of magnitude. The cuticular wax content of the different plant species did not effect the short-term sorption kinetics of 2,3,7,8-TCDD.
