Anthropogene Störung des Stickstoff-Kreislaufs

Nitrogen compounds accumulate in soils and the atmosphere and penetrate into groundwater reservoirs. This already affects terrestrial ecosystems, water and air quality, and the climate now and will even influence these parameters more in the future. Some of the effects only develop slowly, but the underlying processes can barely be influenced. Ecological precaution cannot be limited to a minimization of the exposure of organisms by xenobiotics, but should be equally concerned with the effects of anthropogenically enhanced concentrations of natural compounds upon organisms and ecosystems.
