Mobilization of aluminum by the acid percolates within unsaturated zone of sandstones

Popis výsledku v původním jazyce

The area of the Black Triangle has been exposed to extreme levels of acid deposition in the twentieth century. The chemical weathering of sandstones found within the Black Triangle became well-known phenomenon. Infiltration of acid rain solutions into the sandstone represents the main input of salt components into the sandstone. The infiltrated solutions?sandstone percolates?react with sandstone matrix and previously deposited materials such as salt efflorescence. Acidic sandstone percolates pH?3.2?4.8found at ten sites within the National Park Bohemian Switzerland contained high Al-tot (0.8?10 mg?L1) concentrations and high concentrations of anions SO4 (5?66 mg?L1) and NO3 (2?42 mg?L1). A high proportion (50?98 %) of Al-tot concentration in acid percolates was represented by toxic reactive Aln+. Chemical equilibrium modeling indicated as the most abundant Al species Al3+, AlSO4 +, and AlF2+. The remaining 2?50 % of Al-tot concentration was present in the form of complexes with dissol
