Nutrient pollution released to freshwater and coastal areas comes from many diverse sources including agriculture, aquaculture, septic tanks, urban wastewater, urban stormwater runoff, industry, and fossil fuel combustion. The process of heightened biological productivity in a body of water is call eutrophication. Answer (1 of 4): Eutrophication is nutrient pollution: high nitrogen and phosphorus loads to waterbodies result in problems such as harmful algal blooms. One example is the "bloom" or great increase of phytoplankton in a water body as a response to increased levels of . CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Many coastal waters of developed nations have experienced widespread and rapid eutrophication (the increase in supply of organic matter) during the last half of the 20 th century. Then, excess nutrients run off from the field into the water. Keeping animals and their waste out of streams keeps nitrogen and phosphorus out of the water and protects stream banks. This causes the rapid growth of algae and other plants. This phenomenon relies on plant and dense algal growth due to the enrichment of nitrogen and phosphorus nutrients. What is Eutrophication: Definition, Causes, and Effects. Compared to research on eutrophication in lakes, there has been significantly less work carried out on rivers despite the importance of the topic. Eutrophication can be defined as a process of enrichment of water by nutrient salts that causes structural changes to the aquatic ecosystem. This has resulted in increased phytoplankton production, decreased water clarity, often-severe depletion of dissolved oxygen in bottom . All living things need phosphorus - in fact, it's one of the ingredients in the fertilizers we give our house and garden plants and our agricultural crops to help them grow. A process called eutrophication. Eutrophication represents one of the most severe problems concerning open water sources, like reservoirs, oceans, and lakes. For many lakes, as they age over centuries, there is a buildup of nutrients, sediment, and plant material, which slowly fill the lake basin. The major factors controlling eutrophication in a body of water, whether large, small, warm, cold, fast-moving, or quiescent, are nutrient input and rates of primary production. A list of common ways to decrease the problem of eutrophication are: - Nutrients Limitation - Algae Filtration Figure 1 - Eutrophication at a waste water outlet in the Potomac River, Washington, D.C. drainage pipes and is treated by a wastewater facility, these facilities are ill-equipped to remove nutrients released by The correct answer is Nitrogen and phosphorous.. Concept: Eutrophication: It is an enrichment of water by nutrient salts that causes structural changes to the ecosystem. Harmful algal blooms , dead zones , and fish kills are the results of a process called eutrophication — which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters. Eutrophication, or excess nutrients in streams, is typically one of the top reasons that a stream is listed as impaired on the 303(d) list as part of the Clean Water Act. Scientists and Environmentalist must carefully monitor the quality of fresh water in ponds, lakes and any potential site for eutrophication so that it can be prevented before it may commence. The main effects caused by eutrophication can be summarised as follows (N. Sechi, 1986): In addition there are . During this condition, a layer of algae develops on the sea's surface. Table 1.5. The Sources and Solutions: Agriculture. 78% of global ocean and freshwater eutrophication (the pollution of waterways with nutrient-rich pollutants) is caused by agriculture 3; 94% of mammal biomass (excluding humans) is livestock. Eutrophication- The term eutrophication is used to refer to the excessive growth of algae, plants and animals in water bodies due to the nutrient enrichment of the water body with nitrogen and phosphorous.
