Eutrophication is the main environmental problem caused by phosphorus pollution. Eutrophication deteriorates the water quality leading to the mortality of fish and plants. Moreover, it also reduces the use of the water for human purposes such as consumption and swimming.

Of all known nutrients, Phosphorus and Nitrogen have been historically identified as the major environmental concerns with respect to water quality. While P is perhaps of greater concern in terms of ecological quality of fresh waters, nitrate-N is of concern because it renders water unsuitable for drinking without further treatment. Phosphorus concentrations as low as 10 micrograme per litre have been known to reduce water quality. Studies have also shown that accelerated eutrophication of fresh water is commonly associated with transport of P and N from agricultural areas. This occurs because P and N are typically limiting nutrients in aquatic systems. Generally, increases in P and N concentrations increase, primary productivity in water resources which stimulates algae bloom and therefore eutrophication and subsequently, fish kill, and new species invasion. In conclusion, a major factor that alters the ecological structure and performance of water resources is elevated nutrient inputs. One such framework is its primary productivity which depends on nutrients and light as essential resources and, is limited by the availability of nitrogen (N), phosphorus (P) or a combination of both (NP co-limitation).

It may cause eutrophication in water bodies thus results in algal bloom, which eventually results in reduced DO levels and high BOD.

Eutrophication is the main environmental problem caused by phosphorus pollution. Eutrophication deteriorates the water quality leading to the mortality of fish and plants. Moreover, it also reduces the use of the water for human purposes such as consumption and swimming.

phosphorus in the water causes algae to grow faster than ecosystems can handle

Water body becomes eutrophic & self purifying ability of water is lost.

Well, eutrophication is one of the consequences. Increased turbidity due to excess algae. Precipitation of other nutrients such as calcium, magnesium

It is depend on phosphorus concentration in water. It may reduce dissolved oxygen and produces algal toxins which can be harmful to human and animal health.

1. Eutrophication

2. Loss of biodiversity in aquatic eco-system

3. Algal bloom

High levels of phosphorous in water results in nutrient pollution which causes decrease in dissolved oxygen level in water environment due to active algal growth. The consequence is death of aquatic organisms such as fish and plants. Similarly, it reduces the quality of water for human consumption.

A nicely written issue on nutient pollution.

Phosphorus is a common component of mineral and manure fertilizers because it boosts crop yields. However, a large portion of phosphorus applied as fertilizer is not taken up by plants, and either builds up in the soil or washes into rivers, lakes and coastal seas. Phosphorus load exceeded the assimilation capacity of freshwater bodies in 38 percent of Earth's land surface, an area housing 90 percent of the global human population. Eutrophication due to phosphorus pollution causes algal blooms, which can lead to the mortality of fish and plants due to lack of oxygen and light, It also reduces the use of the water for human purposes such as consumption and swimming.

Phosphorus is a common constituent of agricultural fertilizers, manure, and organic wastes in sewage and industrial effluent. It is an essential element for plant life, but when there is too much of it in water, it can speed up eutrophication (a reduction in dissolved oxygen in water bodies caused by an increase of mineral and organic nutrients) of rivers and lakes. Soil erosion is a major contributor of phosphorus to streams. Bank erosion occurring during floods can transport a lot of phosphorous from the river banks and adjacent land into a stream, lake, or other water body.

Hello Dr Manal Hadi Kanaan

Thank you so much for your detailed explanation

Dear Dr Isa Baba Koki

Thank you for your detailed response

Best regards

High concentrations of phosphorus usually result in producing algal toxins which cause many adverse effects to other organisms. In addition, phosphorus can cause increased growth of large aquatic plants, and decreasing the levels of dissolved oxygen (DO) in water.

Hello Bayan Khalaf

thank you so much

Eutrophication, possible acidification, possible phosphorus cytotoxicity, possible cellular breakdown, changes in biodiversity ( harmful succession) etc. Basically there must be a reason why it's rather scarce than over-abundant.

The increase of phosphorus in water bodies will lead to the presence of nitrogen to the phenomenon of nutritional enrichment and works to increase the young plants and algae and increase the vegetative growth that affects the environment of aquatic organisms as well as the low concentration of oxygen, especially at dawn. Phosphorus is one of the active elements in the chemical medium and leads to the formation of numerous compounds In the aqueous medium, toxic substances are formed according to the environmental conditions, as well as melted phosphorus, which is difficult to get rid of.

Dear Dr Nidhal Tahseen

The excess level of Phosphorus in the water creates algae to grow faster than the ecosystems can handle. Over-growth of algae disturbed the water quality, habitats, food resources, and reduce the oxygen level that fish and other aquatic life need to survive.

1. Phosphorus (note the correct spelling) in the form of phosphate, is an essential nutrient for all life. 2. In aquatic systems, especially freshwater lakes, ponds, and reservoirs, an overabundance of phosphorus, by stimulating primary production, can lead to algae blooms, including harmful algae, oxygen depletion, eutrophication, and fish kills. 3. The most common source of excess phosphorus in natural waters is runoff of fertilizers from agricultural systems, although poorly treated sewage is another important source.

IN ORGANOPHOSPHOR PESTICIDES IT IS DEADLY BUT IT IS HANDLED PROPERLY

Both nitrogen and phosphorous play a major role in the eutrophication of aquatic ecosystems. Concentrations of unionized ammonia greater than 10 μgNH3/L can be expected to impair aquatic communities while a phosphorus value higher than 0.5 mg/L constitutes a factor of pollution.

Phosphorus spontaneously ignites on contact with air, producing toxic fumes (phosphorus oxides). Phosphorus reacts violently with oxidants, halogens, some metals, nitrites, sulfur, and many other compounds, causing a fire and explosion hazard.

In most cases excessive phosphorus in the environment specifically water could lead to algae bloom which has a lot of environmental and economic importance. The environmental importance or effect could be seen as depletion of dissolved oxygen in the water bodies by the algae bloom. This would lead to death of aquatic lives. Economic importance or effect is a result of aesthetic defect and disruption of movement of ships, boats and the likes as a result of algae bloom on the surface of water bodies.

Your question has already been answered by our colleagues above and that's fine. Regards.

Phosphorus is an active and effective component in the environment, in addition to being involved in biological processes and energy production in living organisms, but it does not have a role in nature, such as hydrogen oxygen, and if it is found dissolved in water, it will carry water sources and be stable in the oceans and it is difficult to reuse it, but the presence of some plants Like azola and duckweed, they can reuse it within the food chain because these two plants have a high capacity for rapid growth, which may reach in the best conditions by doubling their living mass in less than a day and have the ability to store phosphorus above the plant’s need in order to benefit from it in the event of its low concentration in water Thus, we can recycle phosphorous in the natural world, rather than having its presence a problem. thank you very much

please find the following information

Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. Significant increases in algae harm water quality, food resources and habitats, and decrease the oxygen that fish and other aquatic life need to survive.

Halo dear friends

I need information by extracting materials of vital value in feeding fish from the fats of both duckweed and azola plants, which are floating aquatic plants.

Thank you for sharing your knowledge

Hello dear .

phosphorous is the second major plant nutrient. In living organisms, phosphorous is part of proteins adenosine) nucleic acids. Phosphate to the phosphate ester bonds in adenosine triphosphate It is the main energy storehouse (adenosine diphosphate) and adenosine diphosphate (triphosphate).The transfer of energy in cells was connected. Adenosine Triphosphate is a high-energy nucleotide that has a ribose sugar (Adenosine) and three phosphate groups. Breakdown of adenosine triphosphate releases a large amount of The energy that the cell uses for its various activities. Adenosine diphosphate has the sugar ribose and two groups

phosphate. Adenosine diphosphate is used to synthesize adenosine triphosphate with the energy released in respiration Cellular. When adenosine triphosphate is used for cellular activities, diphosphate is reconstituted Adenosine. In plant cells, adenosine triphosphate is produced in mitochondria and chloroplasts.

In addition to converting energy inside cells, phosphorous plays a role in cell growth, stimulating root growth at a time Early, and in the production of fruits and seeds. In humans and animals, phosphorous is essential for the growth of bones and teeth.

Manufactured from Calcium Phosphate. Phosphorous is present in the environment as organic phosphorous, i.e. as part of living or organic matter

And - 2) H2PO and its conjugate bases) - 5) H3PO is dead, or as inorganic phosphates, phosphoric acid 5) Orthophosphate is shortened to phosphate. As in carbonic acid, the distribution of (PO5) and -3 (HPO5) Phosphate families are a function of the pH
