The concentration of ammonia in livestock and poultry houses depends on the temperature, feeding density, ventilation, ground structure, feeding and management level, and fecal pollution removal. Because ammonia is easily soluble in water, the concentration of ammonia is relatively high when the ...
Compared to an earlier similar study covering all the measured transitions of NH3 [Al-Derzi et al., J. Quant. Spectrosc. Rad. Transfer 161 (2015) 117鈥 130], the present investigation is limited to transitions with an upper energy level below 7500 cm1, considers 82 sources (28 new) of ...
TYPE OF TEST : LCLo - Lowest published lethal concentration ROUTE OF EXPOSURE : Inhalation SPECIES OBSERVED : Human DOSE/DURATION : 5000 ppm/5M TOXIC EFFECTS : Details of toxic effects not reported other than lethal dose value TYPE OF TEST : ...
(dashed grey lines). Ammonium never increased above the level of detection (5 µM) and urea concentrations remained below 2.5 µM (Supplementary Table6).b, NO2−and NO3−production (combined). At the end of the incubation, 78% of the total added guanidine nitrogen was oxidized ...
Flooded Liquid Recirculation Systems:In flooded systems, a pump or pressurized gas circulates a large quantity of liquid ammonia through the evaporator, often exceeding the amount that can be vaporized. This ensures a constant liquid level in the evaporator coil, maximizing heat transfer efficiency. ...

Naturally occurring arsenic, typically harmless in its natural state, can undergo transformation into inorganic arsenic, thereby contaminating groundwater sources used for drinking or irrigating crops. The accumulation of arsenic from one trophic level to another level, depends not only on the total ars...
economic and environmental impacts on sustainable NH3synthesis. As the NO3–reduction to NH3involves 8e−transfers and many possible reaction pathways (NO2, NO2–, NO, N2O, N2, NH2OH, NH3, and NH2NH2)37,38,39, an in-depth molecular level understanding of elementary steps can guide the ...
can cause damage to trachaeal mucous membranes in broilers. As ammonia level increases to 25 ppm and higher, there can be increased damage to lungs and air sacs, leading to respiratory illnesses. The increased ammonia can also cause reduction in body weight and, as mentioned above, a failure...
