Phosphorus toxicity is rare in people with normal kidney function. However, those with kidney problems may experience hyperphosphatemia, or elevated levels of phosphorus in the blood.  Phosphorus toxicity is rare in a healthy person, but could develop if too much is consumed or an individual has kidney problems that interfere with removal of excess phosphorus through the urine. Too much phosphorus can lead to an imbalance between phosphorus and calcium that robs calcium from the bones. Phosphorus is a mineral needed by your body for strong bones and teeth and other body processes. Learn about the functions and sources of this major mineral, as well as what happens to your body if there is too little or too much, in this lesson. 1 In water with low oxygen, white phosphorus may degrade to a highly toxic compound called phosphine, which eventually evaporates to the air and is changed to less harmful chemicals. 2  White phosphorus can build up slightly in the bodies of fish that live in contaminated lakes or streams. White phosphorus is used by the military in various types of ammunition, and to produce smoke for concealing troop movements and identifying targets. It is also used by industry to produce phosphoric acid and other chemicals for use in fertilizers, food additives, and cleaning compounds. a toxic condition caused by the ingestion of white or yellow phosphorus, sometimes found in rat poisons, certain fertilizers, and fireworks. phosphorus poisoning. Poisoning caused by the ingestion of substances containing yellow phosphorus, such as rat poison or roach poison. Yellow phosphorus is used in manufacturing fireworks and fertilizers. 1 White phosphorus is used in the manufacture of munitions, pyrotechnics, explosives, smoke bombs, in artificial fertilizers, rodenticides, phosphor bronze alloy, semiconductors, electroluminescent coating, and chemicals. ( 2 1, 4). 1 White or yellow white phosphorus is either a yellow or colorless, volatile crystalline solid that darkens when exposed to light and ignites in air to form white fumes and greenish light. ( 2 1). 3  The chemical symbol for white phosphorus is P; the vapor has the formula P 4 and the molecular weight is 124.0 g/mol. Phosphorus is a chemical element with symbol P and atomic number 15. As an element, phosphorus exists in two major forms— white phosphorus and red phosphorus —but due to its high reactivity, phosphorus is never found as a free element on Earth. Instead phosphorus-containing minerals are almost always present in their maximally oxidised state, as inorganic phosphate rocks. White phosphorus glows in the dark (when exposed to oxygen) with a very faint tinge of green and blue, is highly flammable and pyrophoric (self-igniting) upon contact with air and is toxic (causing severe liver damage on ingestion). Owing to its pyrophoricity, white phosphorus is used as an additive in napalm. 1 DESCRIPTION: White phosphorus is a toxic substance produced from phosphate-containing rocks. 2  White phosphorus is used industrially to manufacture chemicals used in fertilizers, food additives, and cleaning compounds.  phosphorus poisoning, a toxic condition caused by the ingestion of white or yellow phosphorus, sometimes found in rat poisons, certain fertilizers, and fireworks. Intoxication is characterized initially by nausea, throat and stomach pain, vomiting, diarrhea, and an odor of garlic on the breath. phosphorus poisoning. Poisoning caused by the ingestion of substances containing yellow phosphorus, such as rat poison or roach poison. Yellow phosphorus is used in manufacturing fireworks and fertilizers.
