Commercial grade phosphine derived from aluminum or magnesium phosphide can contain to a variable degree higher molecular weight phosphines including diphosphines. Scientists are scouring the galaxy for "biosignatures" that could provide evidence of simple forms of life. -87 °C, dangerous level ca. 104.1.1 Physical Properties. That makes phosphine potentially what scientists call a biosignature — a chemical signal that can be detected by spectroscopic telescopes that could indicate a planet harbors at least simple forms of life. An international team of astronomers has announced the finding of phosphine gas in the atmosphere of Venus, triggering excitement about the possibility of presence of life forms on that planet. Phosphine is naturally found in blood, cerebrospinal fluid, urine, and saliva. Please take the time to read this and pass it on. 20 insects 2. Preparation of phosgene. 3000-8000 ppm 3. There are a few ways to make phosphine chemically – in the extreme temperatures and pressures inside gas giants like Jupiter and Saturn, for example – but there are no known ways to make it in the atmosphere of a rocky planet like Venus, Petkowski said. What Does Bleach And Ammonia Make Crime Scene Clean Up Crew Crime scene cleaners decontaminate a crime scene, while protecting both themselves and any evidence they find during their work. The researchers have explored all the known chemical processes that could account for the phosphine gas on Venus – even exotic causes like volcanoes, lightning and delivery by meteorites – but they’ve found nothing to explain it. Odor is not an adequate indicator of phosphine's presence and may not provide reliable warning of hazardous concentrations. METHODS OF DISSEMINATION: Indoor Air: Phosphine can be released into indoor air as a gas. 50 ppm in air). Mg 3 P 2 + 6H 2 O à 2PH 3 ^ + 3Mg(OH) 2 Phosphine gas reacts with substances commonly found in the air. “Chemical biosignatures are one of the primary tools we have for looking for life in the universe,” said Caleb Scharf, director of astrobiology at Columbia University in New York, who was not involved in the study. The most widely reported and, perhaps, the most effective chemical agent of the First World War was sulfur mustard, known as "mustard gas".It is a volatile oily liquid. The chemical is phosphine, or PH3, a compound made up of phosphorus attached to three hydrogen atoms. The gas is produced from formulations of metallic phosphides (usually aluminium or magnesium phosphide) that contain additional materials for regulating release of the gas. Phosphine gas is formed by heating white phosphorus with concentrated caustic soda. The reaction that caused the fumigant aluminum phosphide to turn into deadly phosphine is one of the most elementary in chemistry—the acid-base reaction, also known as neutralization. Phosphine is a colorless, flammable, foul-smelling gas that occurs on Earth when organic matter decays, like in dead fish or swamps. Phosphine is a super- toxic gas with a probable oral lethal dose of 5 mg/kg or 7 drops for a 150 pound person. “Until we have a better handle on that, it'll be very hard to say that this phosphine is definitely coming from living things,” he said.
