Its main sources of emission are the decomposition of organic matter and dejections of animals. Ammonia is used by man in diverse activities of production, therefore it is a gas that can contaminate work environments. Measurements of ammonia concentration in some parts of the world have shown great spatial and weather variation. This large variability makes it difficult to estimate the input of reduced nitrogen to different ecosystems from measurements.123-130porAmmoniaNeutralizationVariationammoniaorganic matteratmospherecontaminationdecompositionecosystemenvironmentgas analysisreviewweatherArtigo10.1590/S0100-40422004000100022S0100-40422004000100022WOS:000189167000022Acesso aberto2-s2.0-08422907722-s2.0-0842290772.pdf9165109840414837
