Acidification processes in remote mountain lakes, at high elevations above the timberline, have been identified as a potential further priority area for research. Because of their situation, such lakes are subjected to little pollution other than by long range air pollution. Recent studies have pointed out the low buffering capacity of many of these lakes; these indications, together with the data on forest decay in the Alpine environment, indicate a high sensitivity of this environment to acidification processes. The workshop addressed at first some general geographical, meteorological, physico-chemical and biological features of remote mountain lakes, followed by highlights on the chemical processes occurring in catchments and in the waterbodies, ranging from deposition of acidic substances and geological weathering processes to modelling of exchange processes at the soil/water interface. Historical changes of acidity in remote mountain lakes, in particular drawn from paleolimnological studies on lake sediments, were considered to assist in separating natural from anthropogenic acidification.
