Corrosion of metals depends on the kind of metal and the prevailing conditions in the medium (temperature, pH, pressure, concentration, etc.) as well as the type of ions such as CO3 , NO − 3 , Cl − and NO2 present in the medium. It will be useful to briefly discuss the effects of some ions on metals. The ions mentioned above have different effects on metals. For example, CO3 is adsorbed on the ...

Alkyl nitrites have been problematic worldwide due to their recreational use. Although there is a lack of scientific information on their action on the central nervous system (CNS), many anecdotal reports and case studies have inferred the CNS actions of alkyl nitrites. The objective of this study was to investigate the effects of alkyl nitrites on the CNS, especially focusing on the dopaminerg...

agricultural advancement and population growth have prompted increases in food supplies, and higher crop yields have been made possible through the application of fertilizers. large quantities of livestock and poultry on farms, along with the accumulation of biomass and agricultural residues, can cause contamination of ground water resources and other water sanitation concerns in both developin...

Kinetics of nitrite uptake and reduction by Chlamydomonas reinhardtii cells growing phototrophically has been studied by means of progress curves and the Michaelis-Menten integrated equation. Both uptake and reduction processes exhibited hyperbolic saturation kinetics, the nitrite uptake system lacking a diffusion component. Nitrite uptake and reduction showed significant differences in K(s) fo...

Nitrate and nitrite can be organic or inorganic chemicals depending on their chemical structures. This profile pertains to inorganic nitrate and nitrite, specifically the nitrate anion and the nitrite anion. Nitrate and nitrite occur naturally in the environment as part of the nitrogen cycle, and are produced both endogenously and exogenously. Ammonia-oxidizing bacteria convert ammonia into nit...

a kinetic method developed for the determination of ultra-trace amounts of nitrite based on its catalytic effect on the reaction between potassium bromate and nile blue a in strongly acidic media is reported. the reaction was monitored spectrophotometrically by measuring the decrease in absorbance of nile blue a at 645 nm by the fixed-time method. the decrease in absorbance during the first 0.5...

Nitrite secures essential nitric oxide (NO) bioavailability in hypoxia at low endogenous concentrations, whereas it becomes toxic at high concentrations. We exposed brown trout to normoxic and hypoxic water in the absence and presence of added ambient nitrite to decipher the cellular metabolism and effects of nitrite at basal and elevated concentrations under different oxygen regimes. We also t...

BACKGROUND Generalized hypoxic pulmonary vasoconstriction (HPV) occurring during exposure to hypoxia is a detrimental process resulting in an increase in lung vascular resistance. Nebulization of sodium nitrite has been shown to inhibit HPV. The aim of this project was to investigate and compare the effects of nebulization of nitrite and different formulations of acidified sodium nitrite on acu...
