Elemental yellow phosphorus causes second- and third-degree burns on skin contact and may cause systemic symptoms from absorption. The compound is highly toxic. The acute fatal dose in adults is 15 to 100 mg (1 mg/kg), although survival has occurred after an ingestion exceeding 1 g. The fatality rate varies between 20% and 50%, and the prognosis is good if the patient survives for 6 days.

The human lethal oral dose of phosphorus (white) is about 1 mg/kg body weight, and as little as 0.2 mg/kg may produce adverse effects. Acute oral phosphorus intoxication generally has two stages. In the initial phase gastrointestinal effects predominate and may include nausea, vomiting, and belching. The onset may be within 30 min after ingestion. Death from cardiovascular collapse can occur in about 12 hr. A period of regression and apparent recovery lasting about 2 days may occur. The second stage is characterized by the return of the gastrointestinal distress plus signs of hepatic, renal, and cardiovascular problems, for example, jaundice, pitting edema, oliguria, high pulse rate, and low blood pressure. In either phase, smoking, luminescence, and a garlic odor of the vomitus and feces are characteristic but not diagnostic. The most common pathological findings in deaths have been fatty degeneration of the liver and kidneys.
[Clayton, G.D., F.E. Clayton (eds.) Patty's Industrial Hygiene and Toxicology. Volumes 2A, 2B, 2C, 2D, 2E, 2F: Toxicology. 4th ed. New York, NY: John Wiley & Sons Inc., 1993-1994. 786]**PEER REVIEWED**

A dose of 15 mg of phosphorus can cause severe poisonings in humans and as little as 50 mg may be fatal. Shortly after ingestion phosphorus produces severe gastrointestinal irritation, and if a sufficient dose in ingested, hemorrhage and cardiovascular failure may prove fatal within 24 hours. The vomitus after phosphorus ingestion is luminescent and has a characteristic garlic odor. If the patient survives the initial gastrointestinal irritation phase, secondary systemic poisoning due to liver necrosis may ensue. Severe acute yellow atrophy of the liver is one delayed sequela that may ultimately prove fatal.

White phosphorus is extremely poisonous and can cause "phossy jaw", a disease ... caused by phosphorus fumes that are inhaled or absorbed through cavities in the teeth and that then attack and destroy bones, particularly the jaw bone. Phossy jaw is usually fatal ... .
[Toy ADF, Walsh EN; Phosphorus Chemistry in Everyday Living 2nd ed p.8 (1987)]**PEER REVIEWED**

The most important manifestation of chronic phosphorus poisoning is osteomyelitis of the jaw bones ("phossy jaw"), most frequently of the mandible and less often of the maxilla, which commonly begins as a dental disturbance. If the tooth is extracted, in the subsequent course of the condition, the pressure of a purulent discharge and failure of the tooth socket to heal normally will generally make the dentist suspicious of a severe underlying condition in the bone. In that case, he will allow the infected bone to separate and then remove it surgically, trying to conserve as much as possible of the natural bone outline to avoid facial disfigurement. /Phosphorus/

The mortality rate for acute phosphorus poisoning is approximately 25% for victims who had early symptoms of nausea and vomiting, nearly 50% when both gastrointestinal and CNS symptoms were present, and almost 75% when the first manifestation of poisoning was restlessness, irritability, drowsiness, stupor, or coma. This difference in survival rates most likely reflect the interval between time of ingestion and treatment. The toxic dose is 15 mg, and as little as 50 mg may be lethal.

First aid can be given by standard treatment. After ingestion of white phosphorus a 0.1 M solution of copper sulfate should be given orally until vomiting occurs.

Rabbits and rats were exposed to single doses of smoke from pyrotechnic mixtures containing red phosphorus. The survivors were observed for up to 14 days.

A system was developed which could continuously produce quantities of fresh phosphorus aerosol for several hours for inhalation exposure studies. In a preliminary range-finding study, Sprague-Dawley rats were exposed to red phosphorus derived-aerosol entailing four one-hr (3.2, 4.3, 5.3 or 8.5 mg/l) exposures and one 4-hr (1.5 mg/l) exposure. Rats died on days 1, 2, 6, 8, 9, 10 or 11 after exposure, suggesting both acute and delayed effects. At the lower doses, the laryngeal region appeared to be the most consistent target area with laryngeal and epiglottal ulcerations and edema. Pulmonary congestion, edema and hemorrhage were more pronounced only in the higher dose groups.

Mice and rats were exposed to the smoke produced by ignition of a red phosphorus pyrotechnic composition, 1 hr/dy, 5 dy/week, at two different dose levels, together with controls. The mice received 180 exposures, while the rats received 200 exposures. Guinea pigs also underwent 200 exposures at the lower concentration, but all animals exposed at the higher concentration died during or immediately after the first dose. Growth of the test groups of mice and rats was depressed during the exposure period. Organ specific toxicity appeared not to be present in rats and was generally confined to the respiratory tract of the mice and the guinea pigs. A significantly higher proportion of the test group mouse lung showed aggregates of macrophages containing granules than was present in the control group. Severe congestion was observed in practically all the lung from the decedent high-dose group guinea pigs.

In a one-generation reproduction study, male and female Sprague Dawley rats (15 males and 30 females/group) were orally exposed by gavage to elemental yellow phosphorus in corn oil vehicle at dose levels of 0, 0.005, 0.015 or 0.075 mg/kg/day for 80 days prior to mating (2 females/male), and continued throughout mating, gestation and lactation periods. Due to low fertility in the first litter, the study was extended to 2 litters and dosing continued throughout the entire study. All pups were sacrificed at weaning and parental animals were sacrificed after weaning of the F1b litter. There were significant differences between treated and control animals in the following: decreased F0 male body weights (high-dose group, after 15 weeks of the study). There were no significant differences between treated and control animals in the following: parental mortality, food consumption, fertility indices, mean length of gestation, numbers of viable pups and pup survival, pup body weights, and gross or microscopic examinations at necropsy.

FIFRA Requirements:

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Phosphorus is found on List C. Case No: 3111; Case Status: No products containing the pesticide are actively registered ... The case /is characterized/ as "cancelled." Under FIFRA, pesticide producers may voluntarily cancel their registered products. EPA also may cancel pesticide registrations if registrants fail to pay required fees or make/meet certain reregistration commitments, or if EPA reaches findings of unreasonable adverse effects.; Active ingredient (AI): phosphorus; AI Status: The active ingredient is no longer contained in any registered pesticide products ... "cancelled."

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
