Abstract
This publication provides a scientific synthesis of the current state of research and knowledge about the response of terrestrial and aquatic ecosystems to nitrogen (N) inputs (N deposition or N additions), and, where possible, identifi es critical loads for atmospheric N deposition. It also targets policy makers and resource managers who are seeking a scientific basis for making decisions about the potential broad ecological impacts of air pollution, as well as the impact of specific pollution sources on particular ecosystems.
