Acid-base chemistry of high-elevation streams in the great smoky mountains

Stream-water chemistry in upland streams in the southern Appalachian Mountains of Tennessee and North Carolina was characterized. Spatial and temporal variations in major ions affecting acid-base chemistry were also determined. Catchment processes responsible for observed patterns in stream chemistry, particularly acid neutralizing capacity, were evaluated on the basis of these data. Particular attention was given to biogeochemical controls on sulphate, nitrate and aluminium which were responsible for many acidification-related effects in aquatic ecosystems. Five streams in the Great Smoky Mountains National Park were sampled in this study. There are 74 references.
