Dynamic models are therefore indispensable tools for the assessment of metal concentrations at changing levels of metal inputs to soil-water systems.

Effects and Empirical Critical Loads of Nitrogen for Ecoregions of the United Statesfts in competitive interactions and community composition, changes in species richness and other measures of biodiversity, and increases in invasive species. The range of critical loads of nutrient N reported for U.S. ecoregions, inland surface waters, and freshwater wetlands is 1–39 kg N ha. yr., s

Mass Balance Approaches to Assess Critical Loads and Target Loads of Metals for Terrestrial and Aquaches are also presented to calculate target loads, i.e. deposition levels at which a critical limit is attained within a predefined time horizon. Results are presented for critical loads of Cd in view of food quality, critical loads and target loads of Cd, Pb, Cu and Zn in view of soil biodiversity
