how long does it take potassium cyanide to kill you
Potassium cyanide Potassium cyanide is a potent inhibitor of cellular respiration, acting on mitochondrial cytochrome c oxidase, hence blocking oxidative phosphorylation. This prevents the body from oxidizing food to produce useful energy. Lactic acidosis then occurs as a consequence of anaerobic metabolism. Initially, acute cyanide poisoning causes a red or ruddy complexion in the victim because the tissues are not able to use the oxygen in the blood. The effects of potassium and sodium cyanide are identical, and symptoms of poisoning typically occur within a few minutes of ingesting the substance: the person loses consciousness, and brain death eventually follows. During this period the victim may suffer convulsions. Death is caused by cerebral hypoxia.
Kīlauea The first well-documented eruption of Kīlauea occurred in 1823 (Western contact and written history began in 1778). Since then, the volcano has erupted repeatedly. Most historical eruptions occurred at the volcano's summit or its eastern rift zone, and were prolonged and effusive in character. The geological record shows, however, that violent explosive activity predating European contact was extremely common; in 1790 one such eruption killed more than 400 people, making it the deadliest volcanic eruption in what is now the United States.[5] Should explosive activity start anew, the volcano would become much more of a danger to humans. Kīlauea's current eruption dates back to January 3, 1983, and is by far its longest-duration historical period of activity, as well as one of the longest-duration eruptions in the world; as of January 2011, the eruption has produced 3.5 km3 (1 cu mi) of lava and resurfaced 123.2 km2 (48 sq mi) of land.
