Acidification high-altitude alpine lakes

Acidification Effects on High-Altitude Alpine Lakes. 125... 

In order to verify whether atmospheric deposition directly affects surface water chemistry of high-altitude Alpine lakes, trend analyses were performed for 20 mountain lakes with low alkalinity on the key variables involved in acidification and recovery alkalinity (Gran alkalinity), pH, sulphate, nitrate, base cations (calcium + magnesium). The analysis covers the period 1980-2004 and allows a comparison between atmospheric inputs and surface water quahty.
