Eutrophication Wikipedia. Eutrophication Greek eutrophia from eu well trephein nourish. German Eutrophie, or more precisely hypertrophication, is the enrichment of a water body with nutrients, usually with an excess amount of nutrients. This process induces growth of plants and algae and due to the biomass load, may result in oxygen depletion of the water body. One example is the bloom or great increase of phytoplankton in a water body as a response to increased levels of nutrients. Eutrophication is almost always induced by the discharge of phosphate containing detergents, fertilizers, or sewage, into an aquatic system. Mechanism of eutrophicationeditEutrophication arises from the oversupply of nutrients, which leads to overgrowth of plants and algae. After such organisms die, the bacterial degradation of their biomass consumes the oxygen in the water, thereby creating the state of hypoxia. According to Ullmanns Encyclopedia, the primary limiting factor for eutrophication is phosphate. The availability of phosphorus generally promotes excessive plant growth and decay, favouring simple algae and plankton over other more complicated plants, and causes a severe reduction in water quality. Phosphorus is a necessary nutrient for plants to live, and is the limiting factor for plant growth in many freshwater ecosystems. Phosphate adheres tightly to soil, so it is mainly transported by erosion. Once translocated to lakes, the extraction of phosphate into water is slow, hence the difficulty of reversing the effects of eutrophication. The sources of these excess phosphates are phosphates in detergent, industrialdomestic run offs, and fertilizers. With the phasing out of phosphate containing detergents in the 1. Ubers board was widely expected to be prepared for a vote finalizing its punishing search for a new CEO to replace Travis Kalanick, who resigned earlier this year. Tesla CEO Elon Musk and Google AI expert Mustafa Suleyman are among 116 experts from 26 countries who have signed a letter to the United Nations asking it to ban.

Sodium triphosphate, once a component of many detergents, was a major contributor to eutrophication. Excess nutrients are applied to the soil. Some nutrients leach into the soil where they can remain for years. Eventually, they get drained into the water body. Some nutrients run off over the ground into the body of water. The excess nutrients cause an algal bloom. The algal bloom blocks the light of the sun from reaching the bottom of the water body. The plants beneath the algal bloom die because they cannot get sunlight to photosynthesize. Eventually, the algal bloom dies and sinks to the bottom of the lake. Bacteria begins to decompose the remains, using up oxygen for respiration. The decomposition causes the water to become depleted of oxygen. Larger life forms, such as fish, suffocate to death.

Cultural eutrophicationeditCultural Eutrophication is the process that speeds up natural eutrophication because of human activity. Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays. Extra nutrients are also supplied by treatment plants, golf courses, fertilizers, farms, as well as untreated sewage in many countries. Lakes and riversedit.

When algae die, they decompose and the nutrients contained in that organic matter are converted into inorganic form by microorganisms. This decomposition process consumes oxygen, which reduces the concentration of dissolved oxygen. The depleted oxygen levels in turn may lead to fish kills and a range of other effects reducing biodiversity. Nutrients may become concentrated in an anoxic zone and may only be made available again during autumn turn over or in conditions of turbulent flow. Enhanced growth of aquatic vegetation or phytoplankton and algal blooms disrupts normal functioning of the ecosystem, causing a variety of problems such as a lack of oxygen needed for fish and shellfish to survive. The water becomes cloudy, typically coloured a shade of green, yellow, brown, or red. Eutrophication also decreases the value of rivers, lakes and aesthetic enjoyment. Health problems can occur where eutrophic conditions interfere with drinking water treatment. Human activities can accelerate the rate at which nutrients enter ecosystems. Runoff from agriculture and development, pollution from septic systems and sewers, sewage sludge spreading, and other human related activities increase the flow of both inorganic nutrients and organic substances into ecosystems. Elevated levels of atmospheric compounds of nitrogen can increase nitrogen availability. Phosphorus is often regarded as the main culprit in cases of eutrophication in lakes subjected to point source pollution from sewage pipes. The concentration of algae and the trophic state of lakes correspond well to phosphorus levels in water. Studies conducted in the Experimental Lakes Area in Ontario have shown a relationship between the addition of phosphorus and the rate of eutrophication. Humankind has increased the rate of phosphorus cycling on Earth by four times, mainly due to agricultural fertilizer production and application. Between 1. 95. 0 and 1. Earths surface, primarily on croplands. Policy changes to control point sources of phosphorus have resulted in rapid control of eutrophication. Natural eutrophicationeditAlthough eutrophication is commonly caused by human activities, it can also be a natural process, particularly in lakes. Eutrophy occurs in many lakes in temperate grasslands, for instance. Paleolimnologists now recognise that climate change, geology, and other external influences are critical in regulating the natural productivity of lakes. Some lakes also demonstrate the reverse process meiotrophication, becoming less nutrient rich with time. The main difference between natural and anthropogenic eutrophication is that the natural process is very slow, occurring on geological time scales. Ocean waterseditEutrophication is a common phenomenon in coastal waters. In contrast to freshwater systems, nitrogen is more commonly the key limiting nutrient of marine waters thus, nitrogen levels have greater importance to understanding eutrophication problems in salt water. Estuaries tend to be naturally eutrophic because land derived nutrients are concentrated where run off enters a confined channel. Upwelling in coastal systems also promotes increased productivity by conveying deep, nutrient rich waters to the surface, where the nutrients can be assimilated by algae. The World Resources Institute has identified 3. Western Europe, the Eastern and Southern coasts of the US, and East Asia, particularly Japan. In addition to runoff from land, atmospheric fixed nitrogen can enter the open ocean. A study in 2. 00. It has been suggested that accumulating reactive nitrogen in the environment may prove as serious as putting carbon dioxide in the atmosphere. Terrestrial ecosystemseditTerrestrial ecosystems are subject to similarly adverse impacts from eutrophication. Increased nitrates in soil are frequently undesirable for plants. Many terrestrial plant species are endangered as a result of soil eutrophication, such as the majority of orchid species in Europe. Meadows, forests, and bogs are characterized by low nutrient content and slowly growing species adapted to those levels, so they can be overgrown by faster growing and more competitive species. In meadows, tall grasses that can take advantage of higher nitrogen levels may change the area so that natural species may be lost. Harpoon. 3. 6 1. 98. DB2. 00. 0 Database Scenarios Warfare Sims.
