White phosphorus
Its chemical properties and effects on human health
White phosphorus is a waxy, colorless, white, or yellow solid with an odor resembling garlic. It does not occur naturally but is manufactured from phosphate rocks. White phosphorus reacts quickly with oxygen, igniting easily at temperatures 10 to 15 degrees above room temperature. It is used by the military in various types of munitions, as well as to produce smoke for concealing troop movements and identifying targets. It is a highly reactive and toxic compound, causing large fires. When exposed to oxygen, it spontaneously ignites at around 30°C, producing dense and irritating smoke. White phosphorus is extremely dangerous to human health, causing severe burns, internal injuries, and can damage vital organs, especially when inhaled or ingested. It also has devastating effects on the environment, contaminating soils and waters, and disrupting ecosystems.
