Although S retention is the dominant process in peat soils in the region, drought simulations in the lab using fibric peat collected from a poor fen exhibited as much as a five-fold increase in SO4 2− concentration after drying and rewetting. Given the limited SO4 2− adsorption capacity of mineral soils and the potential drought-induced S release from peatlands in this region where increased S deposition is expected, further investigation of acidification impacts is warranted.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><custom2><style face="normal" font="default" size="100%">Athabasca Oil Sands Region (AOSR)</style></custom2><custom3><style face="normal" font="default" size="100%">http://www.worldcat.org/oclc/608095255</style></custom3><custom4><style face="normal" font="default" size="100%">OSEMB</style></custom4></record></records></xml>
