White phosphorus is the most deadly weapon that human knows. It is used in gas-paralytic bombs; it has the capacity of caking spontaneously fire in the air. In contact with human skin, it produces very bad wounds, deep burns. It can also affect the liver, vital organs like heart or kidneys.In nature phosphorous is not encountered in its pure form. The most common form of phosphate found in the environment is apatite. From phosphates, after industrial refinement the phosphor forms are obtained.There are several phosphor forms, different by colors: white, red and black.Black phosphorus has also proprieties that can be used by human, but there is not black phosphorus in the human body. It is like graphite and has propriety found bought in graphite and black phosphor: it can conduct electricity. Phosphoric acids can also be used by human like fertilizers for agriculture. Our body has also phosphorus. This may seem dangerous, but in the human body, the phosphorus is found with another chemical structure, called phosphate. It is a slat, and it is very safe, because it has lost all the dangerous proprieties. In fact, the phosphate is found almost in every cells of the body, alone or in combinations with other substances, and has very important roles.With calcium, a combination called calcium phosphate can be found in bones, building the bones skeleton. In teeth it can be found like phosphate salt, called hydroxyapatite. Using mouthwash, which contains fluoride, there take places some changes. The hydroxyapatite is converted to fluorapatite, a much more stronger substance that offers protection to teethes for a longer period of time, and is contributing to the stability of teethes. Also phosphate can be fund in every fluid of the body and is a part of the DNA materials.One of the principal’s roles of the phosphor in the human body is in adenosine triphospate, also called ATP. These molecules are involved in every action that takes place in the human body.The ATP is used for the energy storage. These molecules assure that the hart function well, that the lungs can make the air change, the digestion function normally, because all this actions are using energy. In the human body there are few ATP molecules, but there is a cycle of using and reforming the ATP, so that the body can function at optimal level with a few components.The ATP molecules are the ones that are attacked when a paralytic gas bombed is dropped near a human. By blocking them, the body is paralyzed, because it can not do any of its normal function.The quantities of phosphor recommended per day are around 800 mg. Sources of phosphorus are legumes, grain, cereals or nuts and all other foods because it is a critical component of every living organism.By our daily diet a person take around 1000-1200 mg per day much more that is needed.The phosphate deficiency is very rare, because it is very spread in nature. Low intakes of phosphorus can lead to hypophosphate, manifested with anemia, bone pain, osteomalacy, rickets or muscle weakness.Hyperphosphatemia has also negative effects. It can lead to calcification of the non-skeletal tissues. One of the most affected organs is kidneys. By perturbing they’re function can lead to kidney failure. Those persons should follow dialyses to keep them alive, but in some cases dead can occur.Also osteoporosis can result if too much phosphate is in the organism.Accidents involving with phosphor can lead to death. Because of it’s harmfully proprieties, white phosphorus is used in making poison. There have been accidents, persons ingesting by mistake rat poison and died at once.
