Several studies have examined the toxicity of white phosphorus smoke in humans and animals (White and Armstrong et al. Also the lack of phosphorus can be affected by certain drugs (eg, diuretics). 2 In one study mortality rate was recorded as 50% 3 and, in another study, 48% of those who ingested large doses. As a result, symptoms of phosphorus toxicity when they do occur are actually symptoms of iron and/or zinc deficiency. Systemic toxicity has been described extensively in the animal model. Phosphorus is a mineral found in many foods like beer, cheese, beans, and fish. Phosphine residues were detected in … Acute (short-term) oral exposure to high levels of white phosphorus in humans is characterized by three stages: the first stage … The appearance of symptoms may be sudden and dramatic or they may be delayed. Phosphorus is an essential structural component of cell membranes and nucleic acids but is also involved in several biological processes, including bone mineralization, energy production, cell signaling through phosphorylation reactions, and regulation of acid-base homeostasis. Severe toxic symptoms have been reported following a single oral dose of 15 mg [Sollmann 1943]. Phosphorus deficiency Although phosphorus is enough in food its deficiency is mainly due to certain diseases such as diabetes, starvation, and alcoholism. JAMA. Dietary phosphorus deficiency is uncommon and often only observed in cases of near-total starvation or in rare inherited disorders involvi… In addition, they generate electrical impulses that enable cells to communicate with each other. Higher phosphate levels within the normal range are associated with vascular and valvular calcification in patients with moderate CKD, independent of PTH and calcitriol levels . A person with low levels of phosphorus may experience fatigue, joint pain, or confusion. [] Pathologic changes have been documented in the liver and kidney. DESCRIPTION: White phosphorus is a toxic substance produced from phosphate-containing rocks. Phosphorus is highly toxic to humans and animals. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). A phosphate supplement is typically used to prevent a phosphorus deficiency, a condition considered rare in the United States outside of certain high-risk groups. Ingestion of elemental white or yellow phosphorus typically causes severe vomiting and diarrhea, which are both described as “smoking,” “luminescent,” and having a garlic-like odor. Phosphorus is the principal element in the structure of the nucleus and cytoplasm of all tissue cells. (More information) 2. 1948]. Mild organophosphate exposure may cause: narrowed, pinpointed pupils impaired, blurry vision stinging eyes runny nose watery eyes excess saliva glassy eyes headache nausea muscle weakness muscle twitching agitation Human data: Death has reportedly resulted from a single dose of 1 mg/kg [Smyth 1956]. In addition, some diseases can reduce the digestibility of phosphorus (Crohn's disease, celiac disease). It is also one of the most common substances in your everyday environment and in your body. 1963;186(11):170. doi:10.1001/jama.1963.03710110096052 Download citation file: Transported at high temperatures. White phosphorus is used in the manufacture of munitions, pyrotechnics, explosives, smoke bombs, in artificial fertilizers, and rodenticides. It has been used in the past as a pesticide and in fireworks. This allotrope of phosphorus is extremely toxic and the estimated human lethal dose is 50 - 100 mg. Most people get enough phosphorus in their diet, but some … Red phosphorus is not considered to be potentially toxic as it is insoluble, nonvolatile, and unabsorbable. Phosphorus has a garlic-like odor and, when exposed to air, it … Phosphorus Poisoning in Humans. Background. 1. DESCRIPTION: White phosphorus is a toxic substance produced from phosphate-containing rocks. According to a studyfrom Harvard Medical School, phosphorus deficiency is most commonly seen in: 1. people with chronic obstructive pulmonary disease(affecting 21.5 percent) 2. chronic alcoholics (up to 30.4 percent) 3. people in intensive care units (up to 33.9 percent) 4. people involved in major trauma, such as a severe burn (75 percent) 5. people wit… Sources Food sources. A reduced concentration of phosphate in the blood serum is a disorder known as hypophosphatemia. Abstract Maintenance of phosphate balance is essential for life, and mammals have developed a sophisticated system to regulate phosphate homeostasis over the course of evolution. phosphate toxicity, and discuss future directions for the management of phosphate balance in individuals with normal and impaired kidney function. This compound can have mild effects like affecting the skin upon direct contact or the eyes in case of white phosphorus gas. Phospate omeostatis In humans, w85% of the total phosphate is in the bone and teeth,10% to15%isinsoft tissues, and <1%isinextracellular Correspondence: Masafumi Fukagawa, Division of Nephrology, Endocri- Hazard Summary. Citation. Fumigation with phosphine gas is by far the most widely used treatment for the protection of stored grain against insect pests. Severe toxic symptoms have been reported following a single oral dose of 15 mg [Sollmann 1943]. This page was last edited 20:20, 1 February 2019 by, https://www.wikem.org/w/index.php?title=Phosphorus_toxicity&oldid=205077, Two naturally occurring forms: red and white phosphorus, Red is not absorbed well, limited toxicity, Toxicity largely due to inadvertent production of white phosphorus or phosphine gas during manufacture, Exposure predominantly from use as incendiary munition by armed forces (though occasionally used in manufacture of fertilizers, food additives, and cleaning compounds), Caustic and cellular poison; ignites spontaneously in air, forms phosphorus pentoxide, which then reacts with water to form phosphoric acid, Damage due to both thermal and chemical burns, Vomit and other secretions may have garlic-like odor, Phosphorus particles may fluoresce under Wood's lamp. (1998). Yellow phosphorus (white phosphorus) is a significantly more hazardous form of the element and may be present as a contaminant in red phosphorus. 1980, 1981; Starke et al. (1947) study is a report of the health effects observed in workers exposed to white phosphorus smoke during a factory fire. [] These changes result in the development of progressive anuria, decreased creatinine clearance, and increased blood phosphorus levels. However, due to the dependence of phosphate elimination on the kidney, humans with decreased kidney function are likely to be in a positive phosphate balance. Signs of Toxicity - Humans. It is also a universally distributed component of skeletal, nerve, and muscle tissues. Very high phosphorus intakes over short periods (e.g., two 6,600 mg doses of sodium phosphate taken in one day) can cause hyperphosphatemia [69,70]. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here. Phosphorus is highly toxic to humans and animals. Make an edit and help improve WikEM for everyone. 1950; Newburger et al. Table 4-1 summarizes the composition of phosphoric acids in RP-BR smoke. The potassium concentration is balanced again… Excess phosphorus in the body occurs frequently and may be more concerned than the lack of it. Chronic poisoning is the poisoning which occurs as a result of repeated, small, non-lethal doses over a long period of time. The highly flammable phosphorus-based compounds have been found in human and animal faeces, but in tiny quantities. Symptoms of phosphorus deficiency are: Overdose [] Pathologic changes have been documented in the liver and kidney. Phosphorus is found in most food because it is a critical constituent of all living organisms. Each of the electrolytes has a specific role in the body with potassium being the major positive ion within the cells. This allotrope of phosphorus is extremely toxic and the estimated human lethal dose is 50 - 100 mg. Biologic: No specific test for elemental white or yellow phosphorus is available; however, an elevated serum phosphate level might indicate that an exposure has occurred. JAMA. Although phosphate production is a by-product of elemental phosphorus metabolism in humans, a normal phosphate concentration does not rule out an elemental phosphorus exposure. Systemic toxicity has been described extensively in the animal model. Dysfunction of phosphate regulation has serious clinical consequences. Also the lack of phosphorus can be affected by certain drugs (eg, diuretics). The Walker et al. 1935; Brown et al. A high intake of phosphorus leads to: nonskeletal calcification of tissues (especially the kidneys, where it creates a kidney stone). Two naturally occurring forms: red and white phosphorus; Red is not absorbed well, limited toxicity. 1950; Newburger et al. Yellow phosphorus (white phosphorus) is a significantly more hazardous form of the element and may be present as a contaminant in red phosphorus. Ingestion: mucus membrane irritation/burns, Chronic exposure associated with mandibular osteonecrosis ("phossy jaw"), Phosphorus in Krokodil likely contributes to the significant skin, vascular, and muscle damage that earned it the nick name "the flesh-eating drug", Serum phosphorus level NOT helpful in diagnosing (though may want to monitor if concern for other electrolyte abnormalities), Remove contaminated clothing, wash exposed areas with soap and water, Submersion in water/wet dressings can prevent spontaneous ignition of phosphorus particles, Manually debride/remove remaining phosphorus particles- may need wood's lamp to find, Inhalation: manage airway (may have significant irritation/edema), give, Rehydrate if significant GI losses, correct electrolyte abnormalities. Ingestion up to 1.5 grams have also been reported following a single dose of 1 mg/kg [ Smyth 1956..
