Eutrophication

Eutrophication, a form of water pollution, threatens freshwater ecosystems and is the cause of many frightening deteriorations within freshwater environments. An influence on eutrophication is nutrient loading. To be able to examine the relationship between nutrient loading and eutrophication, one must: understand the basis of nutrient loading, the human contribution to nutrient loading, the problems nutrient loading poses to freshwater ecosystems, and the process of nutrient loading management. By knowing these main topics, one can better assess the negative impact nutrient loading has on eutrophication. Nutrient loading is the given number of nutrients entering an ecosystem at a certain point in time. A defining detector of nutrient loading…

Introduction Eutrophication is a condition in an aquatic ecosystem where high nutrient concentrations stimulate blooms of algae (e.g., phytoplankton). Eutrophication is a natural process that occurs to all lakes over time as the weathering of rocks and soils from the surrounding area that leads to an accumulation of nutrients in the water. It can also be caused by run-offs of fertilisers. Three of the key components of modern fertilisers are nitrogen, phosphorous and potassium. After a rainy…

1. Eutrophication Introduction Due to the rapid development of agriculture and modern farming, the occurrence of eutrophication has becoming more common nowadays. However, what is actually eutrophication? What are the main factors that lead to eutrophication? Can we witness the backlash due to this phenomenon? What measures can we do to reduce the impact to the water quality and the environment? What is eutrophication? • Eutrophication is known as the artificial nutrient enrichment of an…

Eutrophication is a natural occurrence over the past centuries as bodies of water age and contains sediment (Carpenter 1981). However, due to human activities, the rate of eutrophication has increased and now plays a big role in fish kills. This happens when inordinate amount of fertilizers flow down the rivers and streams and into the sea, which in turn encourages algae and most, if not all, aquatic plants to overgrow. Fishes will then suffocate due to lack of oxygen and sunlight excessively…

Literature Review There are endless ways the environment is being affected globally. There are drastic changes occurring all over the world, from deforestation to excessive water pollution. One urgent issue facing the world today is freshwater pollution and the negative effects it is having on freshwater aquatic life. Pollution is creating a positive feedback loop in our freshwater aquatic life, including the killings of many of freshwater wildlife. Through the analysis of several different…

When there is a higher phosphate level in the water, this indicates a higher chance of eutrophication, caused by a runoff from the land causing excessive richness of nutrients in the water. In our experiment, we have relatively low levels of phosphates, the canal’s phosphate level may trigger periodic blooms, however long term eutrophication will not occur. This is because long-term eutrophication will “usually be prevented if total phosphorus levels are below .5 and .05 ppm”(Black). The next…

consists of two distinct basins, the north basin which makes up approximately 75% o f the lake surface area and reaches 100 kilometres wide, while the south basin is up to 46 kilometres wide. The Lake is home to a staggering assortment of aquatic life, a wellspring of water to the animals that populate its shores, and it’s a major flyway for migrating birds. Over the years, researchers have shown the deteriorating water quality in the lake, some of the causes of the deteriorating water quality…

Ecological impacts of the pollution on local environment. Eutrophication: Eutrophication is rapid growth of phytoplankton and other aquatic organism in aquatic environment in response to excess addition of nutrients such as nitrogen and phosphorus. Eutrophication can be caused by natural or cultural processes. Natural eutrophication occurs naturally when a lake or stream ages over a century or thousands of years, while cultural eutrophication is anthropogenic in nature. Eutrophication cause in…

street because clippings contain phosphorus. The incremental runoff of the nutrient phosphorus from sources like lawn fertilizer is a serious concern in cities and suburbs because it feeds algae and weeds in waterways. Fertilizers that use white phosphoric acid as the Phosphorus source are more expensive because of the costly treatment process. There isn’t any difference in Phosphorus fertilizer sources as long as nutrient analysis differences are taken into account. Both nitrogen and…

trophic state of the lake. In order to find out what the limiting nutrient was, we performed a few different tests. We began with a secchi disk test to see the transparency of the water. Then, we took water samples that we later used to test the turbidity levels of the water after adding varying amounts of phosphorous and nitrogen. Phosphorous was the limiting nutrient in the lake, because it had the most growth even when it was paired with nitrogen. Our data was proven to be statistically…
