Acidification and weathering processes in high mountain lakes in Southern Alps

  title={Acidification and weathering processes in high mountain lakes in Southern Alps},
  author={Aldo Marchetto and Alberto Barbieri and Rosario Mosello and G. Tartari},
About 200 lakes in Southern Alps (Italy and Switzerland) were studied in order to quantify their acidification. Although samplings were carried out in summer, long after the acid shock caused by snowmelt, some lakes were found to be acidic and 47% of them show alkalinity values of below 50 µeq 1-1. Losses in alkalinity (acidification levels) were evaluated using a titration model with variable F-factor. Factor analysis shows that the main factors influencing water chemistry are related to rock… CONTINUE READING
