A Review of Nitrate and Nitrite Toxicity in Foods
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...

متن کاملIon chromatography for determination of nitrite and nitrate in seawater using monolithic ODS columns.
A fast and highly sensitive ion chromatographic method using monolithic ODS columns was developed for the determination of nitrite (NO2-) and nitrate (NO3-) in seawater. Two monolithic ODS columns (50 mm x 4.6 mm i.d. + 100 mm x 4.6 mm i.d.) connected in series were coated and equilibrated with 5 mM cetyltrimethylammonium chloride (CTAC) aqueous solution. The column efficiency with 0.5 M NaCl a...
متن کاملDetermination of Nitrate and Nitrite Content of Dietary Supplements Using Ion Chromatography
Nitrate, a compound of low toxicity, when ingested orally, is absorbed from the gastrointestinal tract in its free form. About 20-28% of this is then secreted into saliva and only 4-8% of the ingested nitrate is converted into nitrite by nitrate reducing bacteria. The resulting nitrite is then further reduced to nitric oxide by the same bacteria [1-3]. Many studies have related the beneficial e...
متن کاملThe investigation of pyrocatechol electrochemical mechanism in presence of nitrite ion on platinum electrode
In this study, the electrochemical mechanism of catechol in presence and absence of nitrite ion, is investigated in phosphate buffer medium (pH=7) using platinum electrode through cyclic voltammetry method in various scan rates. Electrochemical oxidation of catechol showed how quinone has changed to o-benzoquinone and also how o-benzoquinone has reacted with nitrite ion and potential scan rate ...
