L’ammoniac d’origine agricole : impacts sur la santé humaine et animale et sur le milieu naturel

Abstract : Most of the gaseous ammonia emissions are from agricultural origin : the livestock sector contributes to 80% of this total. Ammonia is a harmful gas which can injure the respiratory tract of animals and humans (asthma, chronic bronchitis) and can affect animal performances. The return of ammonia compounds to the biosphere occurs through dry and wet deposition, either near the emitting source or following long transport distances (particularly with the ammonia species). Such deposition has several consequences: (1) the availability of both essential and toxic nutrients to plant growth is affected causing nutrient imbalances and increasing the sensibility to secondary factors; (2) the effects on soil and water ecosystems lead to eutrophication (nitrogen enrichment) and/or acidification with the disappearance of fauna and flora in the extreme situation.
