After skin exposure, onset of symptoms may be immediate or delayed for 30 to 60 minutes. The pH of the intermembrane space would increase, the pH gradient would decrease, and ATP synthesis would stop. How much cyanide is too much depends on the route of exposure, the dose, and duration of exposure? The major sources of cyanides in water are discharges from some metal mining processes, organic chemical industries, iron and steel plants or manufacturers, and publicly owned wastewater treatment facilities.

The number one differential diagnosis is probably carbon monoxide inhalation. Cyanide's main effect is that it inhibits oxidative phosphorylation, a process where oxygen is utilized for the production of essential cellular energy sources in the form of ATP. As quickly as possible, wash any cyanide from your skin with large amounts of soap and water. The pH of the intermembrane space would increase, the pH gradient would decrease, and ATP synthesis would stop. In addition, patients treated with hydroxocobalamin should avoidsun exposure to prevent photosensitivity. Complex III (and, it seems, Complex IV) contains an Iron-Sulphur protein (also known as "Rieske"-protein), in which the iron-atom "oscillates" between the Ferric and the Ferrous states, facilitating temporary acceptance of the electron (s).
