摘要: Deposition monitoring may generally serve at least one of the following purposes: (a) determining ecosystems risk, (b) evaluating temporal and spatial trends, (c) developing numerical models, or (d) estimating deposition effects. In this paper, an overview available knowledge about methods is given. Furthermore, it tried to illustrate (dis)agreement between results obtained using different methods. It might be concluded that throughfall, micro meteorological (supplemented/supported by inference) watershed balance (S saturated systems) yield similar estimates annual mean total sulphur, within acceptable uncertainly limits (∼ 30%). A larger uncertainty exists estimate reduced oxidized nitrogen base cation fluxes. clear for individual in general, dry particular, can still not quantified with sufficient accuracy. The various have advantages drawbacks choice a certain method estimation flux specific pollutant ecosystem many cases depend on purpose study requirements accuracy costs.
