This work introduces a wireless, solid-state, portable, and automated device capable of semi-continuously measuring the total ammonia (ammonia (NH3) and ammonium (NH4 + )) levels of fluids, including biological samples. This device reliably measures the total ammonia of biological samples (e.g., urine) faster than current ammonia quantification techniques. Medical professionals typically estimate NH4+ levels using error-prone indirect measurement techniques (i.e., urine anion gap), which are time-consuming and are seldom suitable for periodic measurements. Several instantaneous measurements of total ammonia levels in a patient urine could be utilized as an early warning for both acid-base and/or potassium disturbances. Given the devices operation mechanism, it is able to quantify the total ammonia concentration within a biological sample in only five seconds and can simultaneously transmit data to other devices via Bluetooth. The analytical operation demonstrated high sensitivity, high ...

To test the significance of the purine nucleotide cycle in renal ammoniagenesis, studies were conducted with rat kidney cortical slices using glutamate or glutamine labelled in the alpha-amino group with 15N. Glucose production by normal kidney slices with 2 mM-glutamine was equal to that with 3 mM-glutamate. With L-[15N]glutamate as sole substrate, one-third of the total ammonia produced by kidney slices was labelled, indicating significant deamination of glutamate or other amino acids from the cellular pool. Ammonia produced from the amino group of L-[alpha-15N]glutamine was 4-fold higher than from glutamate at similar glucose production rates. Glucose and ammonia formation from glutamine by kidney slices obtained from rats with chronic metabolic acidosis was found to be 70% higher than by normal kidney slices. The contribution of the amino group of glutamine to total ammonia production was similar in both types of kidneys. No 15N was found in the amino group of adenine nucleotides after ...

Background and aim: In acute liver failure (ALF), the brain is exposed to high levels of ammonia. Human studies defining the clinical significance of ammonia in ALF are lacking. This prospective study evaluated the relationship of arterial ammonia levels at admission to complications and survival among patients with ALF. Methods: Eighty consecutive ALF patients admitted from March 2001 to December 2003 were followed up until death or complete recovery. All had arterial ammonia estimation at admission (enzymatic method). Logistic regression analysis was performed to identify independent predictors of mortality. Results: Forty two (52.5%) patients died. Non-survivors had significantly higher median ammonia levels than survivors (174.7 v 105.0 μ mol/l; p,0.001). An arterial ammonia level of = 124 μ mol/l was found to predict mortality with 78.6% sensitivity and 76.3% specificity, and had 77.5% diagnostic accuracy. Patients with higher ammonia levels also developed more complications, including ...

anhydrous ammonia. Dry soil can hold ammonia. It is free ammonia (NH3) and not ammonium that can be lost from soil at application and is damaging to microorganisms and plant roots/seedlings. On the other hand, anhydrous ammonia is essentially pure (over 99 percent) ammonia.

Dr. John Sawyer is a professor of agronomy and extension specialist in soil fertility and nutrient management at Iowa State University. Ammonia; Ammonia; Ammonia gas; Ammonia solution, strong; Ammoniac [French] Ammoniaca [Italian] Ammoniak [German] Amoniaco [Spanish] Amoniak [Polish] Anhydrous ammonia; Aromatic ammonia, vaporole; Caswell No. With the high affinity for water, soil moisture is important for limiting the movement of ammonia, but water does not ultimately determine retention in soil. Only after conversion to nitrate (NO3-), via the nitrification process, can it be lost from soil by leaching or denitrification. Anhydrous ammonia is a clear, colorless gas at standard temperature and pressure conditions and has a very characteristic odor. However data on ammonia escapes has shown this to be an extremely small risk in practice, and there is consequently no control on the use of ammonia refrigeration in densely populated areas and buildings in almost all jurisdictions in the world. ...

The larvae of the mosquito Aedes aegypti inhabit ammonia rich septic tanks in tropical regions of the world that make extensive use of these systems, explaining the prevalence of disease during dry seasons. Since ammonia (NH3/NH4+) is toxic to animals, an understanding of the physiological mechanisms of ammonia excretion permitting the survival of A. aegypti larvae in high ammonia environments is important. We have characterized a novel ammonia transporter, AeAmt2, belonging to the Amt/MEP/Rh family of ammonia transporters. Based on the amino acid sequence, the predicted topology of AeAmt2 consists of 11 transmembrane helices with an extracellular N-terminus and a cytoplasmic C-terminus region. Alignment of the predicted AeAmt2 amino acid sequence with other Amt/MEP proteins from plants, bacteria, and yeast highlights the presence of conserved residues characteristic of ammonia conducting channels in this protein. AeAmt2 is expressed in the ionoregulatory anal papillae of A. aegypti larvae where it is

TY - JOUR. T1 - Ammonia transport. AU - Wingreen, Ned S.. PY - 2004/1/1. Y1 - 2004/1/1. N2 - This review reviews the ammonium/methylammonium transport (Amt) proteins of Escherichia coli and Salmonella enterica serovar Typhimurium. The Amt proteins and their homologs, the methylammonium/ammonium permease proteins of Saccharomyces cerevisiae, constitute a distinct class of membrane-associated ammonia transporters. Members of the Amt family are found in archaea, bacteria, fungi, plants, and invertebrate animals. In E. coli and serovar Typhimurium, the Amt proteins are essential to maintain maximal growth at low concentrations of ammonia, the preferred nitrogen source. Soupene and coworkers showed that a mutant of E. coli with only the low-affinity glutamate dehydrogenase pathway for assimilation of ammonia, which therefore grows slowly at low ammonia concentrations, is not relieved of its growth defect by overexpression of AmtB. A recent study on an Amt protein from tomato concluded that it was a ...

An ammonia converter was constructed using a commercially available platinum catalyst, with the aim of applying it for the measurement of ammonia concentrations. The dependence of the ammonia converter efficiency on the reaction temperature and the ammonia concentration was investigated by measuring the concentration of the converted nitric oxide. The results showed that the catalyst almost completely oxidized ammonia into nitric oxide at temperatures above 600℃ in the tested range of ammonia concentrations. In addition, by combining the ammonia converter with a chemiluminescent NO_x analyzer we were able to measure the ammonia concentration in an ammonia-nitric oxide mixture to an accuracy of within 3% by making a correction due to the oxygen concentration.

A process for the separation of ammonia dissolved in a gaseous solvent is used to recover ammonia during the production of ammonia from a synthesis gas. The process may be used to extract and recover ammonia in either the supercritical region or the subcritical region. The process can be used to remove ammonia from synthesis gas, or other gaseous solvents, by removing ammonia whose chemical potential decreases as the density of the solvent increases. The process utilizes a sorbent to remove the ammonia followed by an in situ regeneration of the sorbent and recovery of the ammonia. Typically, a gaseous solvent containing the ammonia is passed through a bed of sorbent to sorb the ammonia onto the bed of sorbent, thereby producing a purified gaseous solvent. At least a portion of the gaseous solvent is then acted upon to increase its solvent capacity for the ammonia. The increased solvent capacity gaseous solvent is passed through the bed of sorbent in the opposite direction to desorb the ammonia from the

The major excretory product of fish and many other aquatic organisms. Ammonia is formed during the utilization of proteins which the organism receives through its diet. In fish, the majority of ammonia is excreted through the gills.. Ammonia exists in two forms in water, the gaseous or un-ionized form (NH3) and the ionic form (NH4+) which is called ammonium. While the sum of the two forms (called total ammonia) always equals 100%, the percentage present in the water of either form depends mostly on the pH of the water and, to a lesser extent, the water temperature and salinity. For example, assuming a total ammonia concentration of 1 mg/L at a pH of 7.5 and a temperature of 75°F (24°C), the gaseous fraction (NH3) will be 0.0165 mg/L, while the ammonium concentration is 0.9835 mg/L, with the sum of total ammonia equaling 1.0 mg/L. If everything is kept the same except the pH is increased to 8.5, the NH3 value becomes 0.144 mg/L while NH4+ will equal 0.856 mg/L (the sum still equaling 1.0 ...

Ammonia is the major waste product of protein or nitrogenous metabolism in fish and other aquatic organisms. The major source of nitrogen compounds in fishpond culture is the protein contained in the feed. Therefore, the rate of ammonia production of fish is proportional to the feeding rate. It is excreted primarily across the gills, and in urine and faeces. Ammonia is also produced during the aerobic decomposition of organic matter by bacteria.. In water, the total ammonia-nitrogen (TAN) occurs in two forms, unionised ammonia (NH3) which is toxic to fish, and the ammonium ion (NH4) which is relatively non-toxic, except at extremely high concentrations. Ammonia can change from one form to the other creating a balance between the two forms. Water pH and temperature influence the proportion of total ammonia occurring as the toxic (NH3) form.. Consequently, water samples are taken for TAN levels in the afternoon when pH and temperature are at the daily maxima. Ammonia levels then decrease during ...

Interpretive Summary: Ammonia emissions from agricultural systems contribute to poor air quality and pollution of terrestrial and aquatic ecosystems. Various approaches are used to measure and better understand ammonia emission from agricultural systems. A common method for measuring emission or gaseous concentration is to trap ammonia in an acid solution, and later measure the total ammonia content of the solution. In this paper, we present a modification of this method, where the ammonia content of the acid solution is determined indirectly by measuring the solution pH. Ammonia content is calculated from pH by application of a chemical speciation model. The method is rapid and non-destructive, and so can be applied repeatedly to the same acidic solution at a high frequency. Testing of the method through laboratory ...

Glutamine synthetase (GS) catalyzes the recycling of NH4+ with glutamate to form glutamine. Glutamine synthetase is highly expressed in the renal proximal tubule, suggesting ammonia recycling via glutamine synthetase could decrease net ammoniagenesis and thereby limit ammonia available for net acid excretion. This studys purpose was to determine the role of proximal tubule glutamine synthetase in ammonia metabolism under basal conditions and during metabolic acidosis. We generated mice with proximal tubule-specific glutamine synthetase deletion (PT-GS-KO) using Cre-loxP techniques. Under basal conditions, PT-GS-KO increased urinary ammonia excretion significantly. Increased ammonia excretion occurred despite decreased expression of key proteins involved in renal ammonia generation. Following induction of metabolic acidosis the ability to increase ammonia excretion was impaired significantly by PT-GS-KO. The blunted increase in ammonia excretion occurred despite greater expression of multiple ...

Through its important role in the formation of particulate matter, atmospheric ammonia affects air quality and has implications for human health and life expectancy1,2. Excess ammonia in the environment also contributes to the acidification and eutrophication of ecosystems3-5 and to climate change6. Anthropogenic emissions dominate natural ones and mostly originate from agricultural, domestic and industrial activities7. However, the total ammonia budget and the attribution of emissions to specific sources remain highly uncertain across different spatial scales7-9. Here we identify, categorize and quantify the worlds ammonia emission hotspots using a high-resolution map of atmospheric ammonia obtained from almost a decade of daily IASI satellite observations. We report 248 hotspots with diameters smaller than 50 kilometres, which we associate with either a single point source or a cluster of agricultural and industrial point sources-with the exception of one hotspot, which can be traced back to a

Abstract. The variability of atmospheric ammonia (NH3), emitted largely from agricultural sources, is an important factor when considering how inorganic fine particulate matter (PM2.5) concentrations and nitrogen cycling are changing over the United States. This study combines new observations of ammonia concentration from the surface, aboard aircraft, and retrieved by satellite to both evaluate the simulation of ammonia in a chemical transport model (GEOS-Chem) and identify which processes control the variability of these concentrations over a 5-year period (2008-2012). We find that the model generally underrepresents the ammonia concentration near large source regions (by 26 % at surface sites) and fails to reproduce the extent of interannual variability observed at the surface during the summer (JJA). Variability in the base simulation surface ammonia concentration is dominated by meteorology (64 %) as compared to reductions in SO2 and NOx emissions imposed by regulation (32 %) over this ...

Most patients with neurological Lyme Disease and coinfections (i.e., MS, ALS, Parkinsons Disease, Autism), have elevated levels of ammonia in the brain which is neurotoxic. This is due to the fact that the spirochete, Borrelia burgdorferi, produces urease enzymes, and ammonia accumulation results. Sometimes ammonia levels will be elevated in the blood, but many times they are also normal. This is because the ammonia concentration is localized in specific tissues (brain), where the concentration is not high enough to be detected in the blood. But that doesnt mean that ammonia is not causing destruction. It is VERY neurotoxic, and needs to be removed with herbal supplements and diet changes ...

Passive selective catalyst reduction (SCR) systems can be used as aftertreatment systems for lean burn spark ignition (SI)-engines. Their operation is based on the interaction between the engine, an ammonia formation catalyst (AFC), and an SCR catalyst. Under rich conditions the AFC forms ammonia, which is stored in the SCR catalyst. Under lean conditions, the SCR catalyst reduces the engine out NOx using the stored NH3.This study compared the ammonia production and response times of a standard three way catalyst (TWC) and a Pd/Al2O3 catalyst under realistic engine operating conditions. In addition, the relationships between selected engine operating parameters and ammonia formation over a TWC were investigated, considering the influence of both the chosen load point and the engine settings.Tests at the loadpoint of 1500 rpm/2.63 bar break mean effective pressure (BMEP) showed that most ammonia was formed over a TWC at a lambda of 0.93 with a 50% mass fraction burned (MFB) at 3 crank angle ...

Ammonia is known to be a potent neurotoxin that causes severe negative effects on the central nervous system. Excessive ammonia levels have been detected in the brain of patients with neurological disorders such as Alzheimer disease (AD). Therefore, ammonia could be a factor contributing to the progression of AD. In this review, we provide an introduction to the toxicity of ammonia and putative ammonia transport proteins. We also hypothesize how ammonia may be linked to AD. Additionally, we discuss the evidence that support the hypothesis that ammonia is a key factor contributing to AD progression. Lastly, we summarize the old and new experimental evidence that focuses on energy metabolism, mitochondrial function, inflammatory responses, excitatory glutamatergic and GABAergic neurotransmission, and memory in support of our ammonia-related hypotheses of AD.

It is generally accepted that the toxicity of ammonia to aquatic life is dominated by free ammonia (NH3), with the ammonium ion (NH4+) being relatively non toxic. Algorithms for calculating un-ionised ammonia are readily available for freshwater systems. However they have not been sufficiently accurate in saline systems where the fraction of the total ammonia present in the unionised form is dependent on pH, temperature and salinity. Recently Plymouth Marine Laboratory have produced a new algorithm for the N.R.A., specifically to improve our understanding of the behaviour of ammonia in estuaries and coastal waters ...

The raw energy density of liquid ammonia is 11.5 MJ/L,[60] which is about a third that of diesel. Although it can be used as a fuel, for a number of reasons this has never been common or widespread. In addition to direct utilization of ammonia as a fuel in combustion engines there is also the opportunity to convert ammonia back to hydrogen where it can be used to power hydrogen fuel cells or it can be directly used within high temperature fuel cells[61].. Ammonia engines or ammonia motors, using ammonia as a working fluid, have been proposed and occasionally used.[62] The principle is similar to that used in a fireless locomotive, but with ammonia as the working fluid, instead of steam or compressed air. Ammonia engines were used experimentally in the 19th century by Goldsworthy Gurney in the UK and the St. Charles Avenue Streetcar line in New Orleans in the 1870s and 1880s,[63] and during World War II ammonia was used to power buses in Belgium.[64]. Ammonia is sometimes proposed as a practical ...

The optical properties and density of ammonia have not been exhaustively studied despite the relevance of these characteristics in astrophysical scenarios. This work presents new data pertaining to the real part of the refractive index of ammonia at 632.8. nm and the density at different temperatures of deposition ranging from 13. K to ammonias desorption temperature of approximately 110. K. The results indicate a significant variability for both parameters versus temperature: an increase of 50% for the density and of 10% for the refractive index as the temperature increases in the range of 13-60. K; at temperatures greater than 60. K, a constant value is reached for both parameters. This initial variation and the following plateau reflect structural differences in the form of ammonia at low and high temperatures of deposition that can play an important role in the interaction of ammonia with other molecules of astrophysical interest. © 2013 Elsevier Inc ...

Anabaena cylindrica was immobilized in calcium alginate beads and was placed in a batch reactor in the presence of a glutamine synthetase inhibitor (methionine sulfoximide). Ammonia was released in the medium during two days with a rate of 0.35 μ moles h−1mgChl−1. Addition of nitrite to the medium increased the ammonia production as cells used the nitrite reductase pathway to form ammonia. When reactors were placed in anaerobiosis by N2 bubbling, ammonia production was sustained several days and the total ammonia formed was about two fold higher than in aerobiosis. Long term effects of MSX, nitrite and anaerobiosis are discussed.

Ammonia is a key precursor to atmospheric fine particulate matter (PM2.5) and an important component of the reactive nitrogen cycle, with strong implications for both regional air quality and ecosystems [1]. Due to limited information about fertilizer usage, two of the most important ammonia emission sources-i) livestock production and farm practices, and ii) ammonia emission estimates for agricultural fertilization and livestock farming across China-are usually based on time-averaged emission factors and temporal profiles, leading to uncertainties in the evaluation of controls on ammonia in emission levels and control technologies. In this study, we update activity data and emission factors in the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model [2] to improve spatial and temporal distribution of baseline ammonia inventory in China.

Fritz Ammonia Remover Instantly neutralizes toxic chlorine, chloramine, ammonia and heavy metals. Most dechlorinators have no effect on the highly toxic chloramine in city water. When this tap water is added to an aquarium, the chloramine kills fish, corals and plants. A chemical reaction then gives off deadly ammonia. Fish have no chance of survival! Fritz Ammonia Remover is the safe, easy way to neutralize these toxins. It leaves water fresh, clear, clean and free of toxins, perfectly safe and balanced for all fish and aquatic life. Great for treating ammonia buildup in goldfish, turtle or newt tanks, small bowls, desk-top aquariums and tropical community aquariums. 16 oz. Treats 600 gal.

AMMONIA SCAVENGER by PHP 90 capsules. An elevated blood ammonia level can affect your entire body. A by-product of poor protein digestion and impaired Urea cycle function, it can have many damaging effects on the body, including reduction of BH4, the molecule needed for neurotransmitter production and nitric oxide production. This may also impact mental health and increase damaging oxidative stress. Other symptoms of elevated blood ammonia include muscle weakness, fatigue, neurodegenerative diseases,liver and kidney damage and/ or possible failure. Ammonia Scavenger has a specific blend of nutrients to support the Urea Cycle and to safely reduce ammonia in the body.. ...

How to Lower Ammonia Levels in the Body. Ammonia is a normal byproduct of digestion that is usually removed from the body by the liver. If you have elevated ammonia levels, it is typically due to a problem with your liver function....

TY - JOUR. T1 - Growth, activity and temperature responses of ammonia-oxidizing archaea and bacteria in soil microcosms. AU - Tourna, Maria. AU - Freitag, Thomas E. AU - Nicol, Graeme W. AU - Prosser, James I. PY - 2008/5. Y1 - 2008/5. N2 - Ammonia oxidation, as the first step in the nitrification process, plays a central role in the global cycling of nitrogen. Although bacteria are traditionally considered to be responsible for ammonia oxidation, a role for archaea has been suggested by data from metagenomic studies and by the isolation of a marine, autotrophic, ammonia-oxidizing, non-thermophilic crenarchaeon. Evidence for ammonia oxidation by non-thermophilic crenarchaea in marine and terrestrial environments is largely based on abundance of bacterial and archaeal ammonia monooxygenase (amo) genes, rather than activity. In this study, we have determined the influence of temperature on the response of ammonia-oxidizing bacteria and archaea in nitrifying soil microcosms using two approaches, ...
