The aim of the experiment was to evaluate the effect of the gas phosphine on germination and on vigor (accelerated aging and seedling length) of soybean seeds. (1,3) Phosphine is also used as an intermediate in the synthesis of flame retardants for cotton fabrics, as a The risk from acute exposure to phosphine gas was estimated using a critical NOEL of. Loss of phosphine in the corrosion of copper Effect of relative humidity and concentration of phosphine. Phosphine concentrations tested were 0 (control), 250, 500, 1,000, 1,500, and 2,000 ppm.
In total, 46,911 eggs were used. Phosphine Safety Data Sheet P-4643 ... Gas H250 Flam. ABSTRACT. When liquid phosgene is released, it quickly turns into a gas that stays close to the ground and spreads rapidly. Gas 1 H220 Press. As exposure deadens the sense of smell, do not use smell to determine phosphine concentration. INGESTION EXPOSURE: Phosphine is present as a gas at room temperature, so ingestion is unlikely. 1 (Inhalation:gas) H330 Skin Corr. Ocular exposure to phosphine gas has not been known to cause systemic toxicity. From: Reproductive and Developmental Toxicology, 2011 5 ppm (internal dose .1.7 mg/kg) based on the deaths of 4/10 female rats Phosphine is a toxicant gas with strong reducing properties capable of chemical and biologic oxidant effects. At room temperature (70°F), phosgene is a poisonous gas. Phosgene gas may appear colorless or as a white to pale yellow cloud. Most important symptoms and effects, both acute and delayed No additional information available Red and white phosphorus are allotropes, with white phosphorus existing as P 4 molecules and red phosphorus as an amorphous network. With cooling and pressure, phosgene gas can be converted into a liquid so that it can be shipped and stored. H280 Acute Tox. Direct eye contact with liquefied or compressed phosphine gas, which is unlikely, may cause frostbite. Phosphine is a commonly used insecticide in noxious gas form that protects stored products from pest infestation, utilizing oxygen for its toxic effects. Fumigation is a technique employed to eliminate insect pests in stored seeds by using gas. The effects of exposure to any hazardous substance depend on the dose, the duration, how you are exposed, personal traits and ... No information is available regarding reproductive effects in humans exposed to phosphine gas. Phosphine is a colorless gas with an odor that has been described, by various observers, as similar to that of garlic, rotting fish or stale urine. This chapter describes its usage, toxicology, metabolism, and treatment.
It is an odorless and colorless gas with a molecular weight of 34.00 and density of 1.17 at 25 °C. Each jar assigned to a given treatment had three to five vials containing E. postvittana eggs, and each treatment was replicated six times. Exposure to phosphine gas generates acute effects in animals that include lassitude, ataxia, apnea, cardiovascular collapse and renal and pulmonary histopathology. When 1 g of copper turnings (surface area about 47 cm') was exposed to 4.27 mg/l of phosphine in 250 ml flasks at 0, 22, 70 and 100% r.h. the loss of phosphine from the atmosphere was found to be closely related to the relative humidity (Fig. Gas (Liq.) 2).
