How can white phosphorus affect my health?
Little information is available about the health effects that may be caused by white phosphorus. Most of what is known about the effects of breathing white phosphorus is from studies of workers. Most of what is known about the effects of eating white phosphorus is from reports of people eating rat poison or fireworks that contained it.
Breathing white phosphorus for short periods may cause coughing and irritation of the throat and lungs. Breathing white phosphorus for long periods may cause a condition known as "phossy jaw" which involves poor wound healing of the mouth and breakdown of the jaw bone.
Eating or drinking small amounts of white phosphorus may cause liver, heart, or kidney damage, vomiting, stomach cramps, drowsiness, or death. We do not know what the effects are from eating or drinking very small amounts of white phosphorus-containing substances over long periods of time. Skin contact with burning white phosphorus may burn skin or cause liver, heart, and kidney damage.
We do not know whether or not white phosphorus can affect the ability to have children or cause birth defects in people.
