Phosphorus: biological information
Biological role of phosphorus: phosphorus is a key component of biological molecules such as DNA and RNA. Phosphorus is a component of bones, and teeth, and many other compounds required for life. Chronic poisoning of people working unprotected with white phosphorus leads to necrosis of the jaw ("phossy-jaw").

You can use this form to calculate how much phosphorus your body contains. Enter your weight in either kilograms or pounds and click the "Calculate" button. You must enter a number, not text! Elements for which there are no data will always give a value of zero for the weight, no matter what you put in the weight box.
Hazards and Risks
Hazards and risks associated with phosphorus: elemental phosphorus is severely toxic, the white form more so than the red form. Chronic poisoning of those working unprotected with white phosphorus leads to necrosis of the jaw ("phossy-jaw"). Phosphate esters are nerve poisons and should only be handled by a competent chemist. Inorganic phosphate are relatively harmless. Phosphate pollution occurs as a result of leached fertilisers and from many detergents.
