Soil-acid deposition interactions and their possible effects on geochemical weathering rates in British uplands

Abstract
An attempt is made to quantify the effects that acidic pollutant depositions of anthropogenic origins may have on long-term geochemical weathering and soil acidification rates at upland locations. The factors which naturally regulate geochemical weathering kinetics in such areas are summarized, and the possible ways in which deposition acidity may interact with these regulatory factors are examined. Aspects considered include modifications to soil chemical, microbiological and physical characteristics. The ways in which such changes may influence the extent and pattern of mineral weathering are critically discussed.
