White phosphorus, yellow phosphorus, or simply tetraphosphorus (P 4) is an allotrope of phosphorus. It is a translucent waxy solid that quickly yellows in light (due to its photochemical conversion into red phosphorus ), [ 2 ] and impure white phosphorus is for this reason called yellow phosphorus.
People exposed to white phosphorus can suffer severe and sometimes deadly bone-deep burns. It can cause organs to shut down, and burns on just 10% of the body can be fatal, HRW said.
The white phosphorus allotrope presents a significant hazard because it ignites in the air and produces phosphoric acid residue. Chronic white phosphorus poisoning leads to necrosis of the jaw called "phossy jaw". White phosphorus is toxic, causing severe liver damage on ingestion and may cause a condition known as "Smoking Stool Syndrome". [143]
The Berne Convention (formally, the International Convention respecting the Prohibition of the Use of White (Yellow) Phosphorus in the Manufacture of Matches (French: Convention internationale sur l'interdiction de l'emploi du phosphore blanc (jaune) dans l'industrie des allumettes)) of 1906 is a multilateral treaty negotiated in Berne, Switzerland, which prohibits the use of white phosphorus ...
The Pentagon recommended providing the white phosphorus shells to Ukraine as part of several aid packages, including a recent one, as a Presidential Drawdown Authority, according to the officials.
National Security Council spokesperson says Biden administration ‘concerned’ over reports that Israel may have misused the controversial weapons
White phosphorus, yellow phosphorus or simply tetraphosphorus (P 4) exists as molecules of four phosphorus atoms in a tetrahedral structure, joined by six phosphorus—phosphorus single bonds. [1] The free P 4 molecule in the gas phase has a P-P bond length of r g = 2.1994(3) Å as was determined by gas electron diffraction . [ 2 ]
Poor management of phosphorus is leading to water pollution and food shortages, with farmers struggling to afford some fertilisers for their crops.
