"Phosphorus concentrations" refers to the amount of phosphorus present in a substance or environment, like water or soil. It indicates the level or quantity of phosphorus that is measured to understand its presence or impact.
Full definition
Scientists have developed a model which gives the maximum potential capacity of water masses to produce cyanobacteria at
different phosphorus concentrations reaching lakes and reservoirs from agricultural or industrial activities.
Another way your veterinarian can gauge the severity of your pet's kidney problems is to add its blood calcium determination number to its blood phosphorus determination number to get a number called the sCaPP (the Serum calcium -
phosphorus concentration product).
Based on measurements of 45,000 individual plants from 3,680 species, and using high - tech statistical mapping protocols, the team created global maps of plant traits including leaf nitrogen concentration,
leaf phosphorus concentration, and specific leaf area (a measure of area displayed to intercept light per unit investment in leaf biomass).
The
total phosphorus concentrations found in the meltwater of the Leverett Glacier — which includes phosphorus - rich particles — was 10 times greater than concentrations found in Arctic river waters.
They found that phytoplankton were much more efficient at assimilating vanishingly
low phosphorus concentrations than would have been predicted from culture research.
The most notable result of the Ecosystems study was the
high phosphorus concentrations they found in the hypoxic bottom waters compared with the surface waters, where it was almost undetectable.
Specifically, they focused on how different phytoplankton taxa assimilated phosphorus in the same region, and how phosphorus uptake by those individual taxa varied across regions with
different phosphorus concentrations.
Your veterinarian can also add your pet's blood calcium determination to its blood phosphorus determination to get a number called the sCaPP (the Serum calcium -
phosphorus concentration product).
To assess the influence of phosphorus on nitrogen removal, the researchers used a comparative approach — they examined the differences between how much nitrogen goes into lakes and how much comes out downstream — coupled with time - series analyses of nitrogen and
phosphorus concentration in large lakes.
The acute regulation of blood calcium and
phosphorus concentrations is controlled through the actions of PTH and the active form of vitamin D.
After ingestion, vitamin D is transported to the liver, where most of it is stored and converted to 25 - hydroxyvitamin D. Later, in response to parathyroid hormone release initiated by low serum calcium or
phosphorus concentration, vitamin D is transported to the kidneys to be converted to its active form, calcitriol.
