Sensitivity, Load and Time: Aspects of Determining a Target Load for Lake Regionsperties. There is a gradual deterioration of surface water ecosystems with the successive process of acidification. Therefore, the definition of the criteria for what might be considered as harmful is largely a matter of subjective decision. A number of studies have indicated that acidic deposition

Atmospheric Deposition of Sulfur, Nitrogen and Basic Cations onto European Forests: Observations andate deposition to deciduous forests very well, but underestimates deposition to conifers by 30 to 40%. The NH.-N deposition to forest is underestimated by the applied model. The model predictions of NO.-N deposition do not show any bias against observations, but are not better correlated with observ

Modeling Time Patterns of Forest Soil Acidification for Various Deposition Scenariossition. Major model outputs include base saturation, pH and the Al/BC ratio, where BC stands for divalent base cations. The processes accounted for are restricted to geochemical interactions, including weathering of carbonates, silicates and aluminum hydroxides, cation exchange and CO. equilibria. W
