Inorganic phosphorus poisoning

Phosphorus has a wide range of uses. It is used in the manufacture of matches, fireworks, firecrackers, signal bombs, certain synthetic dyes, artificial phosphate fertilizers, pesticides, rodenticides and medical drugs. Old-style matchsticks contain yellow phosphorus and are highly toxic. At present, daily matchsticks produced daily do not contain phosphorus, but some matchbox medicines contain about 40% red phosphorus. Phosphorus sulfide matches, which can be ignited anywhere, contain about 10% of tetraphosphorus trisulfide (P4S3) in toxic substances. Inorganic phosphorus poisoning is mostly caused by the misuse of phosphorus-containing rodenticides such as zincphosphide. The patient's vomitus and feces are bloody, and even a large amount of vomiting can occur within 1 to 2 days, causing coma, shock, and death.
