Despite considerable research in the past decades, acid deposition remains a serious environmental problem for many areas in the northern hemisphere, particularly in the northeast United States (Driscoll and Van Dreason, 1993
David and Lawrence, 1996) and Central and Northern Europe (Ulrich et al., 1980
Nilsson et al., 1983
Rosseland and Henriksen, 1990
Matzner and Prenzel, 1992
DeVries et al., 1995), including the north-east of France in the Vosges mountains (Probst et al., 1990
Boudot et ai, 1994a). Acid inputs may have negative impacts on the chemistry and the biological quality of soils and surface waters, particularly through the appearance of soluble inorganic Al species (some of them being toxic to plants and aquatic communities), nutrient imbalance and low pH. Both forest decline and freshwater impoverishment may be related to acidification processes and its related nutrient imbalance as well as the occurrence of soluble Al (Baker and Schofield, 1982
Boudot et al, 1994).
