Název v původním jazyce

Response of alpine lakes and soils to changes in acid deposition: the MAGIC model applied to the Tatra Mountain region, Slovakia-Poland

Popis výsledku v původním jazyce

A dynamic process-based model of surface water acidification, MAGIC, was applied to 31 representative alpine lakes in the Tatra Mountains (~50% of all alpine lakes >0.3 ha in the lake-district). The model was calibrated to observed lake chemistry for theperiod 1980-2002. Surface water and soil chemistry were reconstructed from 1860 to 2002, given estimates of historical acid deposition, and forecast to 2020 based on the reduction in sulphur and nitrogen emissions presupposed by the Gothenburg Protocol.In the 1860s, all lakes were buffered by the carbonate system and only ~6% of lakes had acid neutralising capacity (ANC) <20 #eq l-1. Lake acidification progressed until 1980s, at which time 23% of lakes had a depleted carbonate buffering system and 33%of lakes had ANC <20 #eq l-1. Reversal of water chemistry from acidification started in the late 1980s as a response to decreasing acid deposition. ANC has increased such that only ~16% of the lake population currently has ANC <20 #eq l-
