Eutrophication is the ecosystem response to an excessive richness of nutrients in an aquatic ecosystem. Normally eutrophication is a non-harmful, natural process that occurs when a body of water is aging. The natural cause of eutrophication is the run-off of nutrients from nearby soil and erosion. However a different type of eutrophication is human-caused which accelerates the aging process and creates environmental issues. When there is an excessive richness of nutrients in a body of water, algae feeds off of these nutrients and creates an algal bloom. Algal blooms are harmful because when they die, a lot of oxygen is used to decompose the remains. This causes hypoxia and sometimes, in severe cases, anoxia. This is bad for the environment because it can destroy aquatic life in affected areas. Fish is one type of sea life that is severely affected by eutrophication.
Unfortunately, eutrophication is much more serious now because of human activity. The rise in eutrophic and hypoxic events have been attributed to the rapid increase of agricultural practices, industrial wastes, ...

Essay on The Pros And Cons Of Eutrophication

- Eutrophication: The eutrophication potential impact category of a WWTP is mostly associated with the emissions to water, mainly due to the phosphorus (P), nitrogen (N) and to a lower extent, biodegradable organics (COD) in wastewater effluent (Gallego et al.,b2008; Limphitakphong et al. 2016; Bai et al., 2017). Thus, the eutrophication potential impact can be decreased immediately by implementing more sophisticated technology to enhance the nutrient removal efficiency (however, generally with increase of other environmental impacts) ()....   [tags: Nitrogen, Eutrophication, Agriculture]

Effects Of Eutrophication On Coastal Waters Essay

- Eutrophication is defined as excessive richness of nutrients in a lake or other body of water. It is frequently due to runoff from the land, which causes a dense growth of plant life and, a subsequent death of animal life from a concentration lack of oxygen resulting from the oxidation of organic matter (Chrislock et al., 2013). Eutrophic systems can be observed to have shallow waters, high concentrations of nutrients, high productivity, and high oxygen usage. This process of eutrophication occurs naturally and is caused primarily by the accumulation of nitrogen and phosphorus....   [tags: Water pollution, Eutrophication, Sewage treatment]

Cultural Eutrophication And Its Effects On The Environment Essay

- Human activities continue to increase the amounts of carbon, nitrogen and phosphorus entering lakes and this may result in serious environmental and human health problems (Chen et al., 2015). Fossil fuel combustion, economic development, the use of pesticides and fertilizers, the increased demand for carbon, nitrogen and phosphorus in human activities, and land-use changes all have a significant impact on transforming carbon, nitrogen and phosphorus cycles (Chen et al., 2015). These changes are bringing serious environmental threats such as global warming, biodiversity decline, air pollution, eutrophication and water quality deterioration (Chen et al., 2015)....   [tags: Soil, Water pollution, Lake, Eutrophication]

Essay about The Effect Of Eutrophication On A Body Of Water

- Eutrophication is the over-enrichment of nutrients in a body of water, due to runoff from the land, which causes a condensed growth of plant life. This occurrence also causes death of animal life from lack of oxygen (Oxford Dictionary, 2016). The nutrients that become overly abundant are nitrogen phosphorus which causes problems in most natural environments. The problems caused by this nutrient are hypoxia and harmful algae blooms. Hypoxia is the depletion of oxygen. If oxygen is taken out of the water where organisms live and breathe then they will die....   [tags: Water, Water pollution, Algal bloom, Oxygen]

Essay about The Effects Of Eutrophication On The Environment

- Another social impact of eutrophication is an overall loss of biodiversity in areas of severe nutrient input due to the hypoxic conditions that can occur. As large amounts of algae go through their life cycles, decomposers subsequently eat the dead algae. As these algae are decomposed, the decomposers use up the oxygen in the surrounding water which leads to low oxygen conditions if carried on for long periods of time. Due to these low oxygen conditions, other organisms such as fish cannot survive in these areas and die....   [tags: Water pollution, Water, Sewage treatment]

Eutrophication in te Chesapeake Bay Essay

- ... A goal was set in 1985 to cut back the percent of nutrients being put into the bay by these two sources. It is thought that redirecting the flow of soil with nutrients in them will reduce the runoff, but if the nutrients seep into groundwater they still get into the Chesapeake Bay. Farmers have ways to help reduce these nutrient levels, but it is not the cheapest way to farm, so not all farmers are doing their part to save the bay. Another contributor of runoff land development. Runoff can occur from exposed land being prepared to be developed, or because of what has been used to replace what used to naturally be....   [tags: excessive nutrients, seafood businesses]

Essay on Cultural Eutrophication

- The process of eutrophication happens when natural as well as artificial nutrients, mostly nitrates and phosphates, find their way into an aquatic or terrestrial ecosystem. When these nutrients are added to a water body or soil the consequences can show up in numerous forms. One that flourishes when there is extra nutrients is the growth of the microscopic organisms known as phytoplankton (blue-green algae) in freshwater rivers and lakes. When there is an overabundance of them in a lake or river they show up as a green color on top of the water....   [tags: Terrestrial Ecosystem, Nutrient Limitation]

Eutrophication Essay

- What is eutrophication. Eutrophication is, in the simplest terms, too much of a good thing. It occurs when too many nutrients are deposited into a body of water, throwing off the established balance of production and consumption of organic matter. Eutrophication can take place in ponds, lakes, rivers, and oceans. At first, the overload of nutrients in the body of water encourages plant growth. However, soon this excess of organic material uses up most of the available oxygen in the water, taking it away from the other plants and animals....   [tags: Geology]

Eutrophication Essay

- Eutrophication comes from the Greek word "eutrophos" meaning well-nourished. In other words, this natural process found in water occurs as a result of additional rich nutrients forming a flourish in plant production. At this moment in time, eutrophication is causing worldwide devastation to not only aquatic life, but the fishing industry. The release of nutrients into fresh water lakes, rivers and reservoirs leads to excessive growth of three different plant species: a) Open water algae (phytoplankton) b) Attached algae (periphyton) c) Higher plants (macrophytes) Above all, these organisms encourage the growth of algae, which absorb dissolved oxygen in the water essential for the surviva...   [tags: Biology]
