Dyes from garments factories and waste from tanneries end up in the rivers. Due to these toxic chemicals, the water has become nothing less than dye. The major victims of water pollution are amphibians and dolphins. A lot of amphibians that hunt insects in our farmlands are dying off. Just because of this, several species of fish and aquatic plants are endangered today.
Frequent growth of water plants and blooms of blue-green algae. >10 Low levels of animal & plant life Frequent growth of blue-green algae (toxic to man & wildlife) (Employees, 2007) 3. Phosphate Test This measures the level of Phosphate in the water and high levels of Phosphate results in a lot of algae which kills other plants. Too much plants in the water will result is more bacteria as the bacteria decompose the dead plants. The bacterium uses the oxygen in the water and decreases the plant and insect life but the oxygen is only used up in dams and rivers which do not really flow.
Analysis of Eutrophication and Its Impact to the Environment Introduction Background of the Statement Environment is a place to live on both humans and animals yet there are problems that can be encountered as time goes by. People may or may not give attention to it but there a lot reasons that people should be concerned about it. It should be given a thought to save the environment because not only humans but as well as animals are being affected. There are chemicals that are being mixed in with the marine systems due to human 's negligence. Throwing off waste in waters may not just simply pollute the aquatic systems but also it may have bigger and deeper results of it that are not being seen.
Streams are essential to humans in terms of domestic, agricultural and industrial use. It is an important part of our ecosystem, providing a shelter for many organisms and also a source of water for consumption. It serves as a means of transportation of goods from one place to another. Polluted streams have a great destructive impact on stream ecosystems due to water contamination which causes a critical drop in oxygen levels and numerous creatures are not able to endure low levels of oxygen in waterways (Seibel, 2011, Cox, 2003). Pollution of the river also leads to decrease in freshwater resources because rivers are among most important sources of freshwater in the world which can lead to an excessive shortage of water in the world (Strayer and Dudgeon, 2010).The effect of water pollution has really caused damage to all living organisms on the earth and in water bodies.
On the other hand it is also comprised of heavy metals and pathogens which may pollute the soil and contaminate food products (McGrath, et al., 1994). Also, the biological content of sewage sludge tends to reduce amount of soil biomass and alter the soil biochemical activity (Häni, Siegenthaler, & Candinas, 1995). Such negative impacts have raised public concerns (Inguanzo, et al., 2002). As a consequence tighter regulations have been established to restrict the implementation of such practices such as the EU Council Directive 86/278/EEC which encourages the right application of sludge in agriculture but at the same time seeks to protect the environment and alternatively human’s health (Kirchmann, Börjesson, Kätterer, & Cohen, 2016). These various methods posses risks to the environment and health to a greater or lesser extent.
Eutrophication occurs when there is an over supply of nutrients in an environment, and can cause serious problems especially in water bodies. The increase in nutrient levels could result in algal blooms which is detrimental to the water resource, as algal blooms disrupt the natural ecosystem that functions in the water resource and take in the oxygen in the water body and blocks out sunlight. As little or no oxygen is present in the water resource, much of the aquatic life dies out, resulting in dead zones. Luckily, dead zones mostly occur in smaller water bodies, and since Loktak Lake is a large one, it did not become a dead zone, but still faces the problem of eutrophication. Eutrophication makes water resources unsafe for use as certain algal blooms, fertilizers or pesticides contain harmful chemicals that is not safe for usage.
The quality of water has declined in Nwanedi River and Luphephe dam as a result of human activities. The human activities that have played a role into polluting the river and the dam include run-off from agricultural industries, run-off from sewage and other activities such as washing clothes in the river leaving chemicals contained in soap. All this activities together have contributed in the high turbidity state of water. The residents have also raise concerns about the state of water. They suspect that the water has been the cause of their many clinic visits as they suffer stomach pains and diarrhoea.
2011). In extreme cases eutrophication may even cause fish populations and various other animals in these areas to die (Raven et al. 2011). This is because the microorganisms in the water break down the sewage into carbon dioxide and water through cellular respiration which needs oxygen to work (Raven et al. 2011).
It is possible when strong water flow will pluck out the bed rock and further loosening the soil particle. 2.2 Ecosystem Generally, flood will cause some kind of disruption to major element or component of ecosystem component. One of the most prominent change is the nutrient component which will affect the health of living things in the ecosystem. 2.3 Wildlife Flood may cost wildlife their habitat, especially the terrestrial wildlife. Their mortality rate may change as lots of them may drown.
Usually water pollution is caused by the waste from sewage, and factories. Water pollution is a serious problem for agriculture and food security, because to grow crops we need water, but when the water is polluted the crops die, or get infection. Here are some solutions to
