The alum then reduces phosphorus levels by inactivating the phosphorus released from these lake sediments, thereby controlling phosphorus in the entire water column. This phosphorus supplied from within the lake sediments is known as "internally loaded" phosphorus, as opposed to "externally loaded" phosphorus supplied by sources outside the ...
Phosphorus can be transferred from the soil in one location to another as food is transported across the world, taking the phosphorus it contains with it. Once consumed by humans, it can end up in the local environment (in the case of open defecation which is still widespread on a global scale) or in rivers or the ocean via sewage systems and ...

EP additives which contain phosphorus/sulfur compounds are corrosive to yellow metals such as the copper and/or brass used in bushings and synchronizers, unless properly buffered; the GL-1 class of gear oils does not contain any EP additives and thus used to be the choice in applications which contain parts made of yellow metals.
New car smell is an odor that is commonly encountered in the interiors of new automobiles and other vehicles. The smell is caused by gases emitted from various manufactured materials, such as leather , plastics and textiles .
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.
Red phosphorus is often used to prepare chemicals where the P-P bond is retained. Upon room temperature action with sodium chlorite, Na 2 H 2 P 2 O 6 is formed. [17] Red phosphorus can be used as an elemental photocatalyst for hydrogen formation from the water. [18] [7] It has also been researched as a sodium ion battery anode. [19] [2]
