Acetonitrile has only modest toxicity in small doses. [11] [19] It can be metabolised to produce hydrogen cyanide, which is the source of the observed toxic effects. [9] [20] [21] Generally the onset of toxic effects is delayed, due to the time required for the body to metabolize acetonitrile to cyanide (generally about 2–12 hours). [11]
Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are toxic metals, toxic chemicals, microbe neurotoxins, radiation particles and even specific neurotransmitters when the system is out of balance. Also some types of drugs, e.g alcohol, [1] and some venom, e.g. from the puff adder (Bitis arietans) or brown recluse ...
Among the most toxic cyanides are hydrogen cyanide (HCN), sodium cyanide (NaCN), potassium cyanide (KCN), and calcium cyanide (Ca(CN) 2). The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa 3 ), the fourth complex of the electron transport chain found in the inner membrane of the mitochondria of eukaryotic cells.

The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile).

Stronger or longer exposure will also lead to convulsions and coma. Very strong exposure causes severe toxic effects within seconds, and rapid death. [2] The blood of people killed by blood agents is bright red, because the agents inhibit the use of the oxygen in it by the body's cells. [2]
Bottom line: No, canola oil isn't toxic, but whether or not it's bad for you as an individual depends on a lot of factors, Taub-Dix says, for example your current health and what else you're eating.
The aqueous solution consists of acrylonitrile, acetonitrile, hydrocyanic acid, and ammonium sulfate (from excess ammonia). A recovery column removes bulk water, and acrylonitrile and acetonitrile are separated by distillation. One of the first useful catalysts was bismuth phosphomolybdate (Bi 9 PMo 12 O 52) supported on silica. [11]
