Eutrophication

Eutrophication is the process which causes ecosystems such as lakes and rivers to increase in fertility due to a higher level of nutrients entering the lake or marine environment (Mayhew, 2015). This results in a growth of plants such as algae. As these algae plants die, aerobic and anaerobic bacteria cause decay, therefore use up the oxygen within the marine environment (Credo, 2015). Eutrophication has significant impacts on water quality of rivers and lakes within the Waikato region. Although…

communities and marine life, and also causing water-borne disease to human’s life, water pollution also might leads to Eutrophication. Eutrophication is an over-enrichment of water with nutrients, usually nitrogen or phosphorus (“Water Pollution”). There are a lot causes of Eutrophication and changes in acidity of water but the main thing that leads to the occurrence of the Eutrophication is silt and chemical pollution. This occur when all fertilizers, herbicides, and insecticides being dump…

expanding, which decreases the water quality and can even be harmful to the economy. Another problem we face with oceanic dead zones is eutrophication. What are dead zones? What is eutrophication? What is their correlation to each other and why are they important? Where are the most notable dead zones found? First I want to look at what dead zones and eutrophication are. A dead zone is a common name for a hypoxic area of water. It is a place where there is limited oxygen. Eutrophic…

Conodoguinet Creek? What pollutes the Conodoguinet creek? Is the Conodoguinet creek even polluted? Is there even a way to find out if it is even polluted? To figure this out we identified and counted critters that we found in the creek. We also took some Eutrophication tests. The first test taken was an Critter Count. How do you count critters or macroinvertebrates? Does the velocity of the creek affect the number critters? First we went out to the creek grabbed a sample rock. Then we counted…

is the third largest freshwater lake in the country. For twenty years, it has been filled with algae due to eutrophication. By 1983, 40% of the total length of the Taihu river was polluted, and by 1996, the figure had risen to 86%, which was the highest in the Chinese water system. (Liang, G., 2012; He, H., 2012) This is because from the year 1993, the Taihu lake had suffered eutrophication. The fertilizers from the nearby farms were not absorbed by the crops and were washed into the lake by…

use patterns on eutrophication in the Ribeira do Iguape watershed. The case study by Cunha, Bottino and Calijuri (2010), examined how land use patterns within the Ribeira do Iguape watershed, Sao Paulo, Brazil, with varied levels of anthropogenic interference influenced eutrophication variables (total suspended solids (TSS), total phosphorus (TP), chlorophyll-a (Chl-a) and total nitrogen (TN)) ranges in three rivers (Canha, Pariquera-Acu and Jacupiranguinha Rivers). Eutrophication is one of the…

In the Baja California coast of Mexico, shrimp ponds were reported to be affected by algal blooms and the responsible algae were the prasinophyte Nephroselmis sp., Cochlodinium polykrikoides, Prorocentrum rhathymum, P. minimum, and Heterocapsa triquetra (dinoflagellates) and Nitzschia sigma (diatom) (Gárate-Lizárraga et al., 1999; 2004; 2006; Sierra-Beltrán et al., 2005; Gárate- Lizárraga and Muñetón-Gómez, 2008). Severe losses in shrimp farming in Mexico caused by toxic dinoflagellates and…

Global warming and climate change are a result of the lifestyle and actions humans have taken over the past one hundred years and through the industrialization era. The burning of fossil fuels in an industrial setting and through divining cars increases the CO2 levels in the atmosphere and consequently warms the Earth. Cutting down and burning forests also has a large impact on global warming and climate change. Trees intake carbon dioxide and release oxygen, so when forests are cut down, the…

conversion (Vershuren et al. 2002, Emmanuel et al. 2007). Both factors mention before contribute with seasonally anoxia that have impacted the composition and dynamics of LV (Vershuren et al. 2002). Additionally, the seasonal rainfall increases the eutrophication in LV and the resuspension of bottom sediment also contributed to the excess in nutrients (Emmanuel et al. 2007). The current status of LV is considered unsteady, due to the high fluctuations that the environment would constantly…
