Phosphorus that runs into freshwater lakes and rivers can cause algal blooms. [16] [19] Phosphate-free detergent reduces the amount of phosphate that wastewater treatment plants must clean up. [16] From the 1960s-2010s the standard way to determine the amount of phosphate in water has been using colorimetry. [20]
Phosphorus is a member of the pnictogens, together with nitrogen, arsenic, antimony, bismuth, and moscovium, and consequently shares properties with them. Phosphorus is an element essential to sustaining life largely through phosphates, compounds containing the phosphate ion, PO 4 3−.
This combustion gives phosphorus(V) oxide, which consists of P 4 O 10 tetrahedral with oxygen inserted between the phosphorus atoms and at their vertices: P 4 + 5 O 2 → P 4 O 10. The odour of combustion of this form has a characteristic garlic smell. White phosphorus is only slightly soluble in water and can be stored under water.
The chemicals in the smoke, which often smell like garlic, can also harm lungs and eyes. During 20th century conflicts, including World War II and Vietnam, the U.S. used white phosphorus against ...

People exposed to white phosphorus can suffer severe and sometimes deadly bone-deep burns. It can cause organs to shut down, and burns on just 10% of the body can be fatal, HRW said.
Phosphogypsum is a by-product from the production of phosphoric acid by treating phosphate ore with sulfuric acid according to the following reaction: . Ca 5 (PO 4) 3 X + 5 H 2 SO 4 + 10 H 2 O → 3 H 3 PO 4 + 5 (CaSO 4 · 2 H 2 O) + HX
The remaining material, rich in nitrogen and phosphorus, can be used as natural fertilizer rather than the usual greenhouse gas-emitting synthetic kind. The dry composting method will be familiar ...
