在过去的三十年里，对欧洲和北美森林生态系统生物地球化学的大量研究表明，大气中矿物元素的沉积强烈影响着它们的功能。土壤酸化、地表水和地下水、氮饱和度和森林衰退是随着矿物元素沉积速率而变化的关键过程（Ulrich 1994; Fenn等人1998; Evans等人2001）。作为生态系统功能的一个例子，可以考虑通过渗漏和径流从生态系统中损失的元素。在整个欧洲范围内，S和N的沉积被证明决定了酸性森林土壤中渗漏和径流的Al损失（Dise等人，2001年），N沉积决定了NO3损失（MacDonald等人，2002年），Mg沉积在很大程度上决定了Mg损失（Armbruster等人，2002年）。
In the past three decades, numerous studies on the biogeochemistry of forested ecosystems in Europe and North America have shown that the deposition of mineral elements from the atmosphere strongly influences their functioning. Acidification of soils, surface- and groundwaters, N saturation and forest decline are key processes that change with rates of deposition of mineral elements (Ulrich 1994; Fenn et al. 1998; Evans et al. 2001). As an example of ecosystem functioning, the losses of elements from the ecosystem by seepage and runoff can be considered. On a European-wide, scale the deposition of S and N was shown to determine the Al losses from seepage and runoff in acid forest soils (Dise et al. 2001), the N deposition to determine the NO3 losses (MacDonald et al. 2002) and the Mg deposition to largely determine the Mg losses (Armbruster et al. 2002).
