Résumé :
|
Nitrogen input to our environment has increased tremendously during the last four decades. Much has arisen from farming and the related agro-industries, such as tanneries and food-processing. As a result there have been negative impacts on human health as well as to our environment due to the surplus nitrogen, such as acidification of soil and waters, eutrophication of valuable water resources including rivers, lakes and coastal waters, and loss of biodiversity in a variety of terrestrial and aquatic ecosystems; oxides of nitrogen also have a major impact on atmospheric chemistry.
