Thus, if sufficient phosphorus is available, elevated concentrations of nitrates will lead to algal blooms. Although levels of 0.08 to 0.10 ppm phosphate may trigger periodic blooms,
Nitrate and nitrite in drinking-water
www.who.int1.3 Major uses and sources in drinking-water Nitrate is used mainly in inorganic fertilizers. It is also used as an oxidizing agent and in the production of explosives, and purified potassium nitrate is used for glass making. Sodium nitrite is used as a food preservative, especially in cured meats.
OXIDATION-REDUCTION REACTIONS

The availability of electrons usually controls the oxidation/reduction reactions and this availability is expressed as redox potentials. Soil microbes often serve as catalysis for the release of electrons from a substance.
