Nitrogen and phosphorus

Nitrogen and phosphorus are considered indicators of eutrophication in closed water bodies such as bays (marine) and lakes, according to the enforcement order of the Water Pollution Prevention Act. They are particularly measured to maintain environmental standards or discharge standards. Ammoniacal nitrogen primarily originates from the decomposition of organic matter in urine and domestic wastewater, as well as from industrial effluents, making it a significant indicator of water quality pollution.
