Some Effects of Ammonia on Plant Metabolism and a Possible Mechanism for Ammonia Toxicity.
Plant injury has been traced to ammonia derived from organic sources such as urine (9), chicken manure (8), cottonseed meal (12) and animal manure (3). In addition, inorganic sources such as aqua ammonia, anhydrous ammonia, and ammonium salts have been reported injurious to plants when placed too close to the root zone (3, 7). The toxicity of ammonia to animals has been demonstrated by Sumner (...
متن کاملAmmonia toxicity and cerebral oxidative metabolism.
Ammonia toxicity and cerebral oxidative metabolism. Am. J. Physiol. 200(3) : 420-424. 1961. -Effects of NH&l on oxidative metabolism of cat cerebral cortex slices and mitochondria incubated in vitro were studied. In slices, addition of IO mM NH&l to the incubation medium resulted in significant (16%) reduction of O2 uptake, doubling of lactic acid production and marked increase of glucose utili...
متن کاملEffects of Ammonia Loading on Porcellio Scaber: Glutamine and Glutamate Synthesis, Ammonia Excretion and Toxicity
The effects of ammonia loading in the terrestrial isopod Porcellio scaber were studied by exposing animals to atmospheres of high PNH3. Isopods show a remarkable tolerance of elevated ambient PNH3, with an LD50 of 89 Pa for a 7-day exposure. However, haemolymph total ammonia concentrations generally remained below 5 mmol l-1 (PNH3=0.37 Pa) over the range of ambient ammonia levels used (6.6­...
متن کاملUse of zeolite for removing ammonia and ammonia-caused toxicity in marine toxicity identification evaluations.
Ammonia occurs in marine waters including effluents, receiving waters, and sediment interstitial waters. At sufficiently high concentrations, ammonia can be toxic to aquatic species. Toxicity identification evaluation (TIE) methods provide researchers with tools for identifying aquatic toxicants. For identifying ammonia toxicity, there are several possible methods including pH alteration and vo...
