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 µM), 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 µM) persisted throughout the Holocene until the industrial period. Then, Ali concentrations continuously increased (up to 28 µM in the mid-1980s) due to atmospheric acidification. Alo (5.5 µM) is predicted to dominate Al concentrations around 2050.
