摘要

In this second part of our review on nitrogen loss to the environment, we discuss the increasing problem of air and water contamination with nitrogenous compounds with a focus on agricultural contributions, water quality standards and legislation andmitigation options available to land managers. Excess nitrogen in soil, aquatic and atmospheric environments is a growing global problem due to human activity increasingly dominating nutrient cycling. While sources of environmental nitrogen pollution arediverse considerable concern exists regarding the impact of intensified agricultural systems and the effects of increasing rates of fertilisation on water and air qualitv which negatively affect human and animal health, increase climate change, ozone depletion and atmospheric nitrogen deposition and cause the deterioration of aquatic habitats. Over recent decades, regional, national and international legislation has been introduced to control and mitigate nitrogen loss from agricultural sources. Whilethe effects of nitrogen on human and animal health have resulted in the introduction of limits that ensure drinking water quality, the role of nitrogen in aquatic eutrophication has greatly been underestimated in the past and the implementation of new standards and laws has been recommended. In addition, a wide range of mitigation measures mostly practical farm management solutions, is available to agriculture to reduce nitrogen loss to the biosphere The involvement of land managers in the decision making and implementation processes is, however, crucial to guarantee the success of measures that optimise agricultural production, minimise adverse effects on human and animal health and reduce environmental pollution Profitable environmentally sound and socially acceptable agricultural production has to be achieved through a joint approach by researchers land managers and policy makers aimed at cost effective, targeted and innovative implementation of mitigation measures to reduce environmental N emissions.
