    Notizen: Abstract Chemical sediment stratigraphy of four high alpine lakes is discussed with respect to atmogenic eutrophication as well as acidification. All lakes show more or less clearly paleoindications of atmospheric, anthropogenic impacts, mainly as slight eutrophication (Schwarzsee and Upper Plenderlesee, Tyrolia, and Gippersee, Carinthia). In Schwarzsee and Goaßelesee (Carinthia), there are weak but not yet significant indications of slight lake acidification, additionally.

    Living in a Dusty World: Airborne Dust as a Key Factor for Alpine Lakes (1999)
    Springer
    Water, air & soil pollution 112 (1999), S. 217-227 
    Details
    ISSN: 1573-2932
    Schlagwort(e): acidification ; dust deposition ; high mountain lakes

    Thema: Energietechnik
    Notizen: Abstract For a long time studies on precipitation and lake-water chemistry have focussed on the deposition of strong acids. Dust in snow and rain was analyzed much less intensively, but recent findings suggest that it may be the missing link which explains why many low-alkalinity lakes in the Alps and the Pyrenees did not become acidic and nutrient levels are seasonally high, whereas lakes in areas which are rarely influenced by dust depositions, for instance in Scandinavia, have acidified. Beside being a dominant factor for nutrient inputs to oceans, rain forests and remote lakes, dust can also play a major role in global warming and cooling, and it may significantly contribute to soil formation at mountain sites in the Mediterranean. I suggest that future changes in dust deposition and warming will be key factors for the development of alpine lakes.
