Soluble and total concentrations Total phosphorus concentrations are more stable, and are thus a more reliable index of the phosphorus status of effluents and natural waters. Limits for total phosphorus concentration in effluent permits for non-aquaculture activities usually are 0.1 to 1.0 milligrams per liter.

PHOSPHORUS IN THE ENVIRONMENT To control eutrophication, the USEPA has established a recommended limit of 0.05 mg/L for total phosphates in streams that enter lakes and 0.1 mg/L for total phosphorus in flowing waters (U.S. Environmental Protection Agency, 1986).

An effluent limitation equal to 1 mg/L total phosphorus as a monthly average shall apply in cases where the discharge of wastewater from all outfalls of a facility other than those subject to ch.

Although there is no actual phosphorus discharge limit for wastewater into general water bodies, it is generally now considered that for a water body to actually achieve 'good' status under the WFD, a limit as low as 0.1 mg/l may be necessary.

The UL for phosphorus for adult men and women ages 19-70 years old is 4,000 mg daily, and for older adults 71+ years, 3,000 mg daily. The UL for pregnant and lactating women ages 14-50 years is 3,500 and 4,000 mg, respectively.

Phosphorus AAS Standard, 1 ml = 1 mg P (1000 ppm P) in H₂O, RICCA Chemical Company. Supplier: Ricca Chemical. Description: 1000 ppm P ion in water. For use in standardizing atomic absorption spectrophotometers.

The EPA-approved method for measuring total orthophosphate is known as the ascorbic acid method. Briefly, a reagent (either liquid or powder) containing ascorbic acid and ammonium molybdate reacts with orthophosphate in the sample to form a blue compound.
