Phosphate is a nutrient needed for plant and animal growth and is also a fundamental element in metabolic reactions. High levels of this nutrient can lead to overgrowth of plants, increased bacterial activity, and decreased dissolved oxygen levels. Phosphate comes from several sources including human and animal waste, industrial pollution, and agricultural runoff.

A key nutrient in ecosystems, phosphates are natural minerals important to the maintenance of all life. Their role in laundry detergents is to remove hard water minerals and thus increase the effectiveness of the detergents themselves. They are also a deflocculating agent; that is, they prevent dirt from settling back onto clothes during washing. ...

phosphate

An additive to drinking water to inhibit corrosion. Phosphates create a protective coating on metal surfaces and reduces its chemical activity, which decreases the processes that lead to corrosion. Zinc orthophosphate is commonly used to control corrosion, such as general corrosion, pitting, and lead or copper control.

phosphate
|
is, in ecological terms, often a limiting reagent in many environments--the availability of phosphate governs the rate of growth of many organisms. Introduction of non-naturally occurring levels of phosphate to those environments causes an ecological disequilibrium, leading to booms in the population of some organisms and subsequent busts in the populations of others deprived of other nutrients or essential elements by the rapid growth and consumption by the booming population.
