Above 330 °C sodium nitrite decomposes (in air) to sodium oxide, nitric oxide and nitrogen dioxide. [88] 2 NaNO 2 → Na 2 O + NO + NO 2. Sodium nitrite can also be used in the production of nitrous acid: 2 NaNO 2 + H 2 SO 4 → 2 HNO 2 + Na 2 SO 4. The nitrous acid then, under normal conditions, decomposes: 2 HNO 2 → NO 2 + NO + H 2 O
Sodium nitrate and nitrite are associated with a higher risk of colorectal cancer. [ 19 ] Substantial evidence in recent decades, facilitated by an increased understanding of pathological processes and science, exists in support of the theory that processed meat increases the risk of colon cancer and that this is due to the nitrate content.
Kenneth Law (born 1965) is a Canadian man who was charged with shipping sodium nitrite, a potentially lethal substance, to people intending to kill themselves. He was arrested in May 2023 on two counts of counselling or aiding suicide. [1] He was later charged with 14 counts of first-degree murder. [2]
Sodium nitrite/sodium thiosulfate, sold under the brand name Nithiodote, is a fixed-dose combination medication used as an antidote for cyanide poisoning. [1] It contains sodium thiosulfate and sodium nitrite. [1] It is given by intravenous infusion into a vein. [1] It was approved for medical use in the United States in January 2011. [2]
The SAD PERSONS scale is an acronym utilized as a mnemonic device.It was first developed as a clinical assessment tool for medical professionals to determine suicide risk, by Patterson et al. [1] The Adapted-SAD PERSONS Scale was developed by Gerald A. Juhnke for use with children in 1996.
Command hallucinations are often considered indicative of suicide risk, but the empirical evidence for this is equivocal. [31] [33] Another psychiatric illness that is a high risk of suicide is schizophrenia. The risk is particularly higher in younger patients who have insight into the serious effect the illness is likely to have on their lives ...
The botulinum toxin as the most toxic substance known has an LD 50 value of 1 ng/kg, while the most non-toxic substance water has an LD 50 value of more than 90 g/kg; a difference of about 1 in 100 billion, or 11 orders of magnitude. As with all measured values that differ by many orders of magnitude, a logarithmic view is advisable.
The nitrate ion. Alkali metal nitrates are chemical compounds consisting of an alkali metal (lithium, sodium, potassium, rubidium and caesium) and the nitrate ion. Only two are of major commercial value, the sodium and potassium salts. [1] They are white, water-soluble salts with melting points ranging from 255 °C (LiNO 3) to 414 °C (CsNO
