Measurement of the deposition and fate of {sup 35}SO{sub 2} in a pine plantation

PDF Version Also Available for Download.

Description

An experiment was carried out to determine the uptake rate and fate of SO{sub 2} absorbed by the forest canopy. The radioactive tracer, {sup 35}S was used. Branches of loblolly pine were exposed to {sup 35}SO{sub 2} in the field with a portable chamber. The exposed branches were excised and a sample of needles was immediately washed with distilled water. The needles and water collected in the field was analyzed for {sup 35}S content. The results indicated that a portion of the {sup 35}S could be washed from the needles and another portion was not removed with a water rinse. ... continued below

The results indicated that a portion of the {sup 35}S could be washed from the needles and another portion was not removed with a water rinse. The portion that could not be removed by rinsing was absorbed at a rate, and followed patterns of absorption, that suggested that absorption was controlled by stomatal diffusion, and thus was internal. The {sup 35}S that could be removed by rinsing appeared to be surface absorption.
