WebSolid phosphides released into natural waters or water systems will generate phosphine gas, which can result in an inhalation hazard. Phosphine gas is non-reactive with and only slightly soluble in water, so if released into natural waters or water systems, it is expected to volatilize from the water and could result in an inhalation hazard. WebJan 1, 2006 · The tablet released 1.1 g (range 1.0-1.2 g) of phosphine in 7 days.
