Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertiary sodium phosphate is valuable as a detergent and water softener.

Phosphates have caused increasing attention recently. The focus is on the environmentally harmful effects in household detergents. Wastewater, from laundering agents, contains phosphates, which are said to be a water pollutant.
Providing an alkaline solution pH 9. Eutrophication is the progressive over-fertilization of water, in which festering masses of algae's blooms, choking rivers and lakes. Phosphorus compounds act as a fertilizer for all plant life, whether free-floating algae or more substantial rooted weeds, and are implicated in eutrophication.
Many countries control phosphate levels, whereas Switzerland has banned the use of phosphates. The marine environment is both fragile and more resistant than the terrestrial ecosystem.
It is fragile for the reasons that nutrients are generally present in very low concentrations, permanently consumed by living organisms and pollutants diffuse rapidly.
Lakes and rivers are extremely complex ecosystems. Nutrients are taken up by both algae and rooted weeds. The weeds act as a shelter for fish larvae and zooplankton, both of which eat algae and are, in turn, eaten by larger fish.
Scientists have concluded that unpolluted lakes can absorb surprisingly large amounts of phosphates without uncertainty. When a fertilizer, such as a phosphate, is added more algae will grow, and consequently will the populations of zooplankton and fish. Difficulties only arise when the lake is already impure.
Zooplankton are sensitive to their environment and many substances are toxic to them. If any of these substances, including phosphates, are present the zooplankton population cannot increase.
Adding phosphates to this polluted system will case algae growth. The floating masses cut off the light supply. Weeds die and decompose using up dissolved oxygen, and causing sulfurous smells and plagues. Deprived of shelter and food, the fish larvae starve. The lake is well on the way to catastrophe.
Without wetlands there would be a minimal amount of fresh drinking water due to the fact that wetlands filter the waters of our lakes, rivers and streams, sequentially reducing contamination of water. The plant growth in wetlands removes phosphates and other plant nutrients washed in from the surrounding soil, consequently restricting the growth of algae and aquatic weeds.
This growth is a serious problem in some of Canada's major waterways, where dead and decaying algae deprive the deeper waters of their oxygen. Researches at Lancaster University have studied lakes whose plant and animal life has been killed by acid rain.
The excess acid in the lakes can be neutralized easily by adding lime, but this makes the waters rich in calcium.
Life will gradually return to the lake but, as these lakes should have low calcium levels, it will not be the same kind of life that existed in lakes before pollution.
The answer, they have concluded, is to add phosphates. These phosphates work by shielding the water. This depends upon nitrate ions in the lake. Contradictory, these ions also are produced by acid rain, contain oxides of nitrogen from combustion sources.Water Pollution occurs when a body of water is severely affected due to addition of large amount of materials to the water.[Missouri Botanical Garden] Pollutions such as sewage and fertilizers contain nutrients such as nitrates and phosphates.
Types of water pollution may be classified by the medium in which they occur, such as surface water pollution, ground water pollution, soil water pollution, etc.; the habitat in which they occur, such as river pollution, lake pollution, estuarine pollution, coastal water pollution, open ocean pollution, etc.; and source or type of contamination.
Essay on Water Pollution: Types, Causes, Effects and Control! When the quality or composition of water changes directly or indirectly as a result of man’s activities such that it becomes unfit for any useful purpose is said to be polluted.
Phosphates are also important in biochemistry. Surface runoff of phosphates from excessively fertilized farmland can be a cause of phosphate pollution in surface waters, leading to eutrophication.
