GB
CAS No. 42001, 7723-14-0
Molecular Formula P4
molecular weight of 123.90

colorless to yellow waxy solid, a garlic smell, dark hair in a light green phosphorescence; vapor pressure 1.3kPa/20 ° C flash point <23 ° C; the temperature of 44.1 ° C; boiling point of 280.5 ° C; solubility : do not dissolve in water, micro - soluble benzene, chloroform, soluble in carbon disulfide; density : relative density (water = 1) 1.82; the relative density (Air = 1) 4.42; Stability : the air separation stable. The air of spontaneous combustion, have white smoke; Risk Marker 9 (spontaneous items), 13 (inorganic Judaipin); The main purposes : special match for raw materials, and for phosphate and pesticides, such as flares manufacturing


2. The impact on the environment :
a health hazard


pathways : inhaled, ingested, percutaneous absorption.
health hazards : acute inhalation poisoning manifested symptoms of respiratory irritation, headache, dizziness, weakness, vomiting, bradycardia, abdominal pain, jaundice, liver size. Severe acute hepatic necrosis, toxic pulmonary edema. Oral mouth erosion poisoning, acute gastroenteritis and even the esophagus, stomach perforation. A few days later there liver and kidney damage. Severe hepatic, renal failure. Fosavance induced skin burns, phosphorus absorption by the skin burns caused poisoning, which occurred severe liver toxicity, kidney damage, acute hemolytic, died as a result.
chronic poisoning : neurasthenic syndrome, digestive disorders, toxic liver disease. Caused bone damage, particularly following jaw significantly, the late mandibular alveolar necrosis and atrophy.


two, toxicology information and environmental behavior


toxicity : it is a high drug category.
acute toxicity : LD503.03mg/kg (rat oral)
subacute toxicity : 0.3mg/kg 117 days, the rabbit by mouth, bone growth system disorders; 150mg/m3, 60 days, rats inhaling, skeletal system barriers to growth, death; 150mg/m3, 60 days, rabbit inhalation, blood system, circulatory system, structure and biochemical changes. Death.
chronic toxicity : long-term exposure to the elements phosphorus workers began indigestion, weakness, anemia, respiratory a garlic flavor, the late Dr biliary disease, mucosal bleeding, urine protein symptoms until death, the autopsy found liver and kidney damage very serious. China discovered the element phosphorus poisoning to chronic liver disease more prominent, the growth inhibitory effect. Foreign conclusion is the liver, kidney, blood system, the nervous system, digestive system with a variety of symptoms, particularly in the liver and kidney lesions most prominent.
Teratogenicity : no relevant reports.
Mutagenicity : mammalian cell culture phenotype genetic tests, many changes.
reproductive toxicity : rat poisoning by mouth lowest dose (TDL0) : 11 µ g / kg (~ 22 pregnant women a day), right index influential male fertility, mortality increased after implantation and fetal change in the number of piglets.


metabolism and degradation : phosphorus chemical nature of the instability in the environment and the air was oxygen contact oxidation P2O5, Er, water generation phosphoric acid, phosphine and Phosphorous Acid (most of P2O5), decreased toxicity. Phosphorus entering mammals most of the state still exists element phosphorus, a small part of the oxidation of a low-phosphorus oxide in the blood circulation and metabolism gradually organic phosphorus and inorganic phosphate.


residues and accumulation : there's no-phosphorus majority still stored in the status quo within the liver and skeleton, interference with intracellular acid phosphatase and ALP functions. Pesticide poisoning, the body phosphorus content increased, and creating a calcium phosphate, and lactate from the increase, resulting in bone calcium deficiency. Poisoning animals pathological anatomy can be seen in liver, kidney and skeletal elements of high levels of phosphorus. Residue from the human element phosphorus from the slow, small part to the form of phosphate metabolites with urine, feces, sweat discharged may also be elements in the form of phosphorus from the faeces of breath and discharges. But most people still left in the body. Aquatic life can be enriched element phosphorus in water, fish right elements phosphorus concentration factor of at least 20 times more, crustaceans aquatic organisms can be enriched even as much as 100 times more. While fish from the elements phosphorus reported rate of 50% / 5.3h.


migration and transformation : It is "international common toxic chemicals concise manual" Sweden quoted "informed Ecology" information. Earth phosphorus in the overall prognosis of the general environment : the world from the air transfer to soil volume is 360 ~ 390 million tons / year; Marine from the air to the volume of 260 ~ 12.3 million tons / year. Fresh water from the soil to 250 ~ 12.3 million tons / year; Freshwater Sediment to 1 million tons / year; Freshwater mud in the end one million tons / year. From freshwater organisms to 10 million tons / year; Freshwater organisms to 10 million tons / year. Water from freshwater to 17.4 million tons / year. Large amounts of phosphorus into the ocean of marine life was then absorbed through the food chain reunification. The information is not right for a separate element phosphorus statistics, only the element phosphorus, mainly through the atmosphere and wastewater into the environment. The exhaust most of phosphorus oxide, a small number dropped to the ground with the dust by atmospheric precipitation scour entered waters, the phosphorus wastewater directly into surface water, phosphorus into the water, the majority of adsorbed on the particle on the sediment into the water and mixed with a small amount of phosphorus to slowly release water, and by oxidation of dissolved oxygen in the water. The sediment phosphorus residue can be very long unchanged.


hazardous characteristics : white phosphorous exposed to air and can cause spontaneous combustion and explosion. The humid air of self-ignition point lower than in dry air of self-ignition point. As with perchlorate oxidizer mixed explosion. Its debris and detrital dry skin after contact with fire, and can cause severe skin burns.
combustion (decomposition) product : oxidation of phosphorus.


3. Emergency Monitoring Methods :
