Abstract
AbstractThe sorption of sulphur dioxide by untreated wood samples has been investigated at a concentration of 90 μg/m3 by use of 35SO2. The softwoods sorbed less sulphur dioxide than the hardwoods and the sites of sorption were different in each class. Most of the sorbed sulphur dioxide was found in the outermost 0.05 mm of each sample and a large portion of it was water‐soluble. The possible role of sulphur dioxide in the weathering of woods is discussed.
