nitriteAny salt or ester of nitrous acid (HNO2). The salts are inorganic compounds with ionic bonds, containing the nitrite ion (NO2−) and any cation. The esters are organic compounds with covalent bonds, having the structure R−O−N−O, in which R represents a carbon-containing combining group and the bonding is from carbon to oxygen. These covalent nitrites are constitutional isomers (see isomerism) of the nitro compounds, nitric acid derivatives (R−NO2), in which the bonding is from carbon to nitrogen. Nitrites are used as food preservatives and color enhancers, though they are so toxic they have caused deaths and combine with amines to produce carcinogens. They are used in medicine to dilate blood vessels. nitrite any salt or ester of nitrous acid nitrite [′nī‚trīt] (chemistry) A compound containing the radical NO2-; can be organic or inorganic.

1987) reviewed the experimental data on reproductive toxicity and reported no evidence of teratogenic effects but found indication that nitrates and nitrites may induce abortion in experimental animals (Fan and Steinberg 1996; Fan et al. They suggest that carcinogens caused by cooking red meat at high temperatures or the nitrites in processed meats may explain the link. When grass crops are stressed, such as by drought conditions, the concentration of nitrates in plant tissues increases because the ability of the plant to reduce nitrates to nitrites is impaired," explains Wallace. |
