What does phosphine gas do to the body?
Inhaling phosphine causes respiratory irritation, compromises heart (cardiac) and circulatory functions, depresses the central nervous system, and produces severe gastrointestinal pain. EYE EXPOSURE: Phosphine gas produces no known adverse effects on the eyes.
How much phosphine is lethal?
A review of 59 poisonings suggests that the minimum lethal concentration of phosphine in air is 7-14 mg m-3, 2-4 h day-1 for several days [13].
What is phosphine made of?
Phosphine is made industrially from white phosphorus by hydrolysis with an alkali metal hydroxide or an aqueous acid–catalyzed disproportionation reaction. The industrial product is normally shipped as liquefied gas.
Can you legally buy red phosphorus?
It is unlawful for any person knowingly or intentionally to possess or distribute red phosphorus, white phosphorus, or hypophosphorous acid, knowing, or having reasonable cause to believe, these substances will be used to illegally manufacture methamphetamine.
Can u buy red phosphorus?
You can actually purchase red phosphorus online, although your source is likely to be located in China or some other part of Asia.
How is phosphine made naturally?
Phosphine is formed naturally via the anaerobic decay of phosphorus-containing organic matter.
How is phosphine made from life?
Earth bacteria are known to make phosphine: they take up phosphate from minerals or biological material, add hydrogen, and ultimately expel phosphine. Any organisms on Venus will probably be very different to their Earth cousins, but they too could be the source of phosphine in the atmosphere.
Where can I find phosphine?
Phosphine is a colorless, flammable, and explosive gas at ambient temperature that has the odor of garlic or decaying fish. Small amounts occur naturally from the break down of organic matter. It is slightly soluble in water.
Is phosphorus harmful to humans?
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. Other signs and symptoms of severe poisoning might include dysrhythmias, coma, hypotension, and death.
Where can you find phosphine?
Where can we find phosphine on Earth?
Phosphine is a chemical compound made up of one atom of phosphorus and three atoms of hydrogen, and scientists have also spotted it on Earth, Jupiter and Saturn. On the gas giants, it’s quite prevalent in the atmospheres, both of which are rich in hydrogen.
How do you make phosphine?
Preparation of Phosphine: Calcium phosphide is mixed with water or dilutes HCl. This results in the formation of phosphine. In the laboratory white phosphorous is heated with concentrated sodium hydroxide solution in an inert atmosphere of CO2 to form phosphine.
What is the smell of phosphine?
Phosphine. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4 ). With traces of P 2 H 4 present, PH 3 is spontaneously flammable in air (pyrophoric), burning with a luminous flame.
What are the side effects of phosphine gas?
Safety. Overexposure to phosphine gas causes nausea, vomiting, abdominal pain, diarrhea, thirst, chest tightness, dyspnea (breathing difficulty), muscle pain, chills, stupor or syncope, and pulmonary edema. Phosphine has been reported to have the odor of decaying fish or garlic at concentrations below 0.3 ppm.
What are the uses of phosphine?
Phosphine is used as an insecticide for the fumigation of grains, animal feed, and leaf-stored tobacco, and as a rodenticide. (1,3)Phosphine is also used as an intermediate in the synthesis of flame retardants for cotton fabrics, as a doping agent for n-type semiconductors, a polymerization initiator, and a condensation catalyst. (1,3)
What is the chemical name of the compound phosphine?
Phosphine is a highly toxic respiratory poison, and is Immediately dangerous to life or health at 50 ppm. Phosphine is also the general name given to the class of organophosphorus compounds of substituted phosphanes—a class of phosphanes in which the hydrogen atoms have been replaced with organic derivative, having a general formula PR 3.
