ew the nature of soil acidity, and synthesize the major processes involved in the net generation and consumption of acidity in forest. Two case studies of loblolly pine (. L.) forests provide examples of how H. budgets are linked with rates of soil acidification.

Sonja M. Salmen,Michael Gröschelitation is normally acidic even in unpolluted areas, where the carbon dioxide in the atmosphere dissolves in water to form carbonic acid, H.CO.. Unpolluted precipitation also contains slight quantities of nitric acid (formed by lightning and by microbial activity) and sulfuric acid (formed from natu

Michael Gröschel,Ralph Kudaounds. An International Workshop was held in September 1995 at the Department for Inland Water Research of the UFZ-Centre for Environmental Research in Magdeburg on the limnology of lakes created by open-cast lignite mining, emphasizing the often observed geogenic acidification after oxidation of py

Jörg WunderlichTable 10.1). Pyrite oxidation takes place when the mineral is exposed to air and water. The process is complex because it involves chemical, biological, and electrochemical reactions, and varies with environmental conditions. Factors such as pH, pO., specific surface and morphology of pyrite, presen

Dorothea Heiss,Bernhard Kuchinkaic (Geller et al., this Vol.). In Germany there are three main districts of lignite surface mining: the Rheinish district near Cologne, the mid-German district around Leipzig and the Lusatian district around Cottbus in the most eastern part of Germany. Surface mining of lignite (brown coal) results
