This review explores the potential adverse impact of the increasing phosphorus content in the American diet on renal, cardiovascular, and bone health of the general population. Increasingly, studies show that phosphorus intakes in excess of the nutrient needs of a healthy population may significantly disrupt the hormonal regulation of phosphate, calcium, and vitamin D, which contributes to diso...

[1] Phosphorus (P) availability constrains both carbon uptake and loss in some of the world’s most productive ecosystems. In some of these regions, atmospheric aerosols appear to be an important, if not dominant, source of new P inputs. For example, previous work suggests that mineral aerosols from North Africa bring significant amounts of new phosphorus to the P-impoverished soils of the Amazo...

Purpose Excess phosphorus from fertilizer application and mobilised soil phosphorus from erosion are partially lost to the aquatic environment where they might cause eutrophication. Phosphorus emissions vary spatially and it is the goal of this study to broaden the scope of the existing inventory to the global scale and to increase the spatial resolution by accounting for relevant environmental...

High specific capacity battery electrode materials have attracted great research attention. Phosphorus as a low-cost abundant material has a high theoretical specific capacity of 2596 mAh/g with most of its capacity at the discharge potential range of 0.4-1.2 V, suitable as anodes. Although numerous research progress have shown other high capacity anodes such as Si, Ge, Sn, and SnO2, there are ...

As early as 1911 Greenwald (1) showed that one of the first detectable results of the removal of the parathyroid glands was a decreased excretion of phosphorus in the urine. In 1913 he (2) extended these studies to show that the effect was on phosphorus directly and not on sodium or potassium. Some years later Greenwald (3) again drew attention to these findings. However, little emphasis was gi...
