Cyanide is a potent cytochrome c oxidase (COX, a.k.a. Complex IV) inhibitor, causing asphyxiation of cells. As such, cyanide poisoning is a form of histotoxic hypoxia, because it interferes with the ability of cells to take or use oxygen via oxidative phosphorylation. [ 25]: 1475. Specifically, cyanide binds to the heme a3-CuB binuclear center ...
Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the −C≡N group is linked by a single covalent bond to carbon.

Adults who aren’t getting enough fluids — as measured by higher sodium levels in the blood — may be more likely to die younger, a National Institutes of Health study published in 2023 found.
Cadmium poisoning. Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where only trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the ...
