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 ...
Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride.Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4).
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.
Produced from phosphate embedded in rocks, white phosphorus is a toxic substance that’s used in fertilizers, cleaning compounds as well as military tools and weapons, according to the Centers ...

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 ...
Vegetable washing generates water with high loads of particulate matter and some dissolved organic matter. It may also contain surfactants and pesticides. Aquaculture facilities (fish farms) often discharge large amounts of nitrogen and phosphorus, as well as suspended solids. Some facilities use drugs and pesticides, which may be present in ...
