Eutrophication

Proposal Background Duckweed also know as Lemna by her genus is a small plant, that is mostly found in sub-polar and tropics regions in ditches, ponds, lakes and slow flow-flowing rivers. Duckweed have the main function of remove waste of water, however the main problem is that grows fast (Moss et al.2012). Research Question Is the use of different concentrations of phosphates will affect the duckweed? Hypothesis The more phosphate use the more the plant will be affected. Aim To…

Threatens the survival of fish and other aquatic life forms. When the nutrients present in the aquatic ecosystems increase, there will cause the phytoplankton and the other photosynthetic plants grow quickly, known as algal blooms. As the result, the algal blooms will limit the oxygen required amount for the respiration by the other aquatic animal and plant species. Oxygen depletion happens when the plant life decrease, die and decompose. When the oxygen dissolved reach the maximum levels, the…

A dead zone is an area that has barely any oxygen due to hypoxia caused by the process of eutrophication (Bruckner, 2017). Eutrophication is the over-enrichment of nutrients in water which causes an overgrowth of algae and hypoxia (US Department of Commerce, 2004). These dead zones are common all over the world and even found in Lake Erie which deals with re-eutrophication. The dead zone in the Gulf of Mexico deals with the same issues as Lake Erie and is one of the largest dead…

A common refrain in 1960 was "Lake Erie is Dead." In the 1960s Lake Erie was terribly polluted. We cleaned it up, but it’s polluted once again. Lake Erie contained increased levels of phosphorus and nitrogen, which contributed to eutrophication, (a process that encourages the development of algal blooms). Since the 1960s Lake Erie has had many problems with algae. Waste water from the sewers also made their way into the lake, as this was happening factories were dumping pollutants into the…

Lake Tahoe is located in the Sierra Nevada mountain range in the northeastern part of California, boarding Nevada. It is well known as a tourist attraction for its great depth and clear cobalt blue waters located at high elevation. The combination of its depth, low ratio of watersheds to lake surface area, and its granite rock geology has lead to the creation of a low fertile and high transparent monomictic lake. Its also unique in that it doesn’t fully mix from top to bottom every year, lake…

Phosphates Phosphates are chemical compounds containing phosphorus. Phosphorus is a non-metallic element which is necessary for life and is found in rock as inorganic phosphates. As water runs over and through rocks it carries off small amounts of minerals such as calcium, magnesium, and phosphates. Phosphates are chemicals containing the element phosphorous, and they affect water quality by causing excessive growth of algae. Read more :…

We have a major role when it comes to the sustainability of the environment we live in today. Now, that we all have more knowledge about the world and how it works we all should understand that each of our action have their own consequences. You would think by us knowing how much we are contributing to ruining the world we all love people would change their ways, but we don’t because we all are very selfish. The most direct way that we are impacting the ecosystem is by polluting it.…

“How are corporate agribusinesses polluting our water” Corporate agribusinesses could potentially be the number one polluter to the water supply today, harming marine life and even humans if the polluted water is consumed. With runoff of an abundance of chemicals from the usage of fertilizers and animal manure, agribusinesses create a huge threat to the health of the environment and all life relying on water purity. Agriculture is cited as” a leading cause of groundwater pollution in the United…

imagined possible. Advances in genetics have become especially important to swine production and, consequently, to the environment as well. Excess phosphorus in manure has the potential to runoff into freshwater sources, causing eutrophication of water and ecosystems. Eutrophication also causes oxygen-depriving algae to bloom and increases fish mortality (Golovan et al., 2001). Not only does this harm our environment but it depletes the limited amount of phosphorus supply available on Earth…
