Název v původním jazyce

Increasing temperature decreases aluminum concentrations in Central European lakes recovering from acidification.

Popis výsledku v původním jazyce

We evaluate the effect of increasing temperature (climate warming) on Al concentrations in four strongly acidified lakes in the Bohemian Forest, Czech Republic, over the 1984-2001 period. Pronounced decreases in atmospheric S and N deposition resulted ina sharp decrease in water concentration of total Al (-0.49 to -1.38 micro mol/l/yr). Residuals from the linear relationship between total Al concentrations and the sum of strong acid anions were inversely correlated with air temperature. An increase inthe average annual air temperature of +1.27 degrees C between 1984 and 2001 explained, on average, 13 of the total Al decrease in the lakes. The inverse relationship between Al solubility and temperature caused lower Al mobilization in soil horizons and/or enhanced precipitation of Al in the lakes at higher temperature but otherwise similar conditions. The recent period of warmer years and mild winters significantly contributes to the trend of decreasing Al in the lakes.
