| Summary: | An experiment was carried out to determine the uptake rate and fate of SO₂ absorbed by the forest canopy. The radioactive tracer, ³⁵S was used. Branches of loblolly pine were exposed to ³⁵SO₂ 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 ³⁵S content. The results indicated that a portion of the ³⁵S 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 ³⁵S that could be removed by rinsing appeared to be surface absorption. |
