Trends in aluminium export from a mountainous area to surface waters, from deglaciation to the recent: Effects of vegetation and soil development, atmospheric acidification, and nitrogen-saturation

Popis výsledku v původním jazyce

We reconstructed the history of terrestrial export of aluminium (Al) to Plešné Lake (Czech Republic) since the lake origin 12,600 BC, and predicted Al export for 2010?2050 on the basis of mass budget studies, palaeolimnological data, and MAGIC modelling.We focused on three major Al forms; ionic Al (Ali), organically-bound Al (Alo), and particulate Al hydroxide (Alp). In early post-glacial time, Plešné Lake received high terrestrial export of Al, but with a minor proportion of Alp (4?25 ?M), and concentrations of Ali and Alo were negligible. Since the forest and soil development (9900?9000 BC), erosion has declined and soil organic acids increased export of Alo from soils. The terrestrial Alo leaching (7.5 ?M) persisted throughout the Holocene until the industrial period. Then, Ali concentrations continuously increased (up to 28 ?M in the mid-1980s) due to atmospheric acidification. Alo (5.5 ?M) is predicted to dominate Al concentrations around 2050.
