Applicability of ammonia sensors for controlling environmental parameters in accommodations for lamb fattening
(2018)
Electrochemical ammonia sensors were used to analyse the existing relationship between the ammonia concentration and ambient levels of both temperature and relative humidity in commercial lamb fattening housing equipped ...
Amônia (NH3) atmosférica: Fontes, transformação, sorvedouros e métodos de análise
(2004-01-01)
Ammonia is the most common alkaline gas of the atmosphere, being important in the neutralization of various processes that occur in the atmosphere. Its main sources of emission are the decomposition of organic matter and ...

Ammonia toxicity in Southern King Crab (Lithodes santolla, Molina 1742) larvae
(Springer, 2019-07)
Effects of ammonia on zoea I of the Southern King Crab, Lithodes santolla (Decapoda, Lithodidae) were analyzed through acute (96 h) and chronic (29 days in total) assays (seven total ammonia nitrogen (TAN) concentrations: ...
Estimating the uncertainty in the atmospheric ammonia concentration in an urban area by Ogawa passive samplers
(2013)
Ammonia, one of the ambient gasses that require environmental monitoring, is typically measured using a passive sampling method. The present work presents an evaluation of the uncertainty according to the Guide to the ...
