Definition Of Water Pollution Environmental Sciences Essay

translation Of Water Pollution Environmental Sciences EssayWater contamination is the straw man of any substances in pee which rat be harmful for plants and animals that live in water supply system or mass who use it. In other word it is the change in the chemical or physical properties of the water and this change mess lead to cause damage and health hazards to animals and plants that live inside it or organisms that use it. (1)Importance of the Nile River for EgyptThe Nile River is the direct water resource in Egypt, where it represents more than 95% of the total water resources in Egypt and it is the lifeline for Egypt and at that countersink are some reasons for its importance which areEgyptians depends on it to acquire fresh water to use it for several(a) purposes such as drinking, cooking, cleaning and other household uses.Use it for agriculture where fertile land organise around the Nile River and they irrigated by Nile River.The Nile River is an important source of fish.It is used in water transportation because it passes from south to northwestward Egypt.Industry in Egypt depends a ken on the waters of the Nile River.Recently after the construction of the elevated Dam became the Nile River is an important source for generating electricity to Egypt. (2)(1) http// http// of pollutionThere are many sources of water pollution in Nile River.Industry WastewaterIndustry is an important user of water. In akin time is an important producer of pollution. Water is very important in diligence. Water demand for industry was 3.6 Billion Cubic Meters BCM/ division in 2000. And they expect to be 5.5 Billion Cubic Meters BCM/year in 2017. So, when industry increases, the water demands increase.(1)Municipal WastewaterIn the city, the water which used by people departure down through various treatment processes to make it healthy as possible before force out it back to environment. Treating water is help to minimize the negative effects of wastewater on the environment. However, some brusque cities along Nile River cannot use treatment facilities which are expensive for them. The only way they can use it is dumped in the river without treated. (2)Statistics show that, all governments generate 3.5 Billion Cubic Meters BCM/year of wastewater. Of these wastewater 1.6 Billion Cubic Meters BCM/year receives treatment. In 2017, 1.7 Billion Cubic Meters BCM/year will receive treatment. Although the capacity will increase yet it will not be able to covers all wastewater. As it is show in table (1) the shape of people serves increase and number of people not served increase because increasing in population. (3)http// E/2002-09%20Survey%20of%20Nile%20System%20Pollution%20Sources-Egypt.pdfSo, it will not be able to decline the amount of wastewater that is not receiving treatment.

And it is in same time contri provideded in water pollution. flood from the agricultural sector frequently contains pollutants that may have an adverse effect on the river. Pollutants such as salts, nutrients like phosphorus and nitrogen, and pesticide residue can be found in this runoff. Agricultural runoff oft is a non-point pollutant, in that it can come from anywhere in a region, and not from a specialized drain. This can make it difficult to There are also problems associated with agricultural runoff seeping into the groundwater as well. (2)Effect of populationT here are many effect of Nile river pollution. Some of these effects areThe presence of oil on the surface of the river works as a buffer between the sun and the plants. This leads to termination of fish and Lack of food for valet. In addition, that will decrease the number of fishermen Many fishermen have both left their jobs altogether or migrated, el-Fikky express. (3)http// solid waste thrown in the river hinder the movement of fishermen net and torn nets which reduces the amount of fish and increase the cost on the fishermen. Saed said he usually catches 2kg of fish a day that equal to US$165 a month, but over the past few months he has had an additional headache his net needs replacing not every month as in the past but every few days, costi ng him up to $144 a month.The Nile river is source for drinking but because it polluted by human that could cause a harmful effect on human and cause a insidious diseases. Not only for people whose drink from it but also for people who eat fish or plant from it. (1)http// crochetWater pollution is a serious problem for the entire world. And it is considered to be one of the most dangerous hazards affecting Egypt. The pollution of Nile River is increase especial in the past few decades.Although the Egyptians love the Nile River a lot and it is important for them, not only in economic terms but it has a significant nub for them. But this did not protect it from pollution.In this report I will explain the meaning of water pollution. Then, I will take nigh the important of Nile River. After that, I will talk some causes of Nile River pollution which are industry wastewater, municipal wastewater and agriculture wa stewater. Final, I will take about effect of Nile River pollution.IntroductionOver two thirds of Earths surface is covered by water less than a third is taken up by land. As Earths population continues to grow, people are putting ever-increasing drag on the planets water resources. One of these fresh water resources is Nile River. Water is essential for life. No organism can live without it. Water pollution is problem effect human, animals and plants. And it caused by antithetic resource. In these report I will try to find the main causes of water pollution in Nile River and the effect of that pollution.SummaryIn the summary, as you see all water pollution in Nile rive and in any place in the world created by human and then he try again to solve it what he already create. I advice all people to maintain the environment. And keep the water clean.ConclusionArent we aware of the different problems occurring in our nature, especially in different bodies of water? Water pollution is th e cause of our undisciplined actions and irresponsibility. We, humans are only creating problems that consequently we will also carry the burden of these problems. We all know that water pollution can affect our health badly and seriously. The solution for all environmental problems is not created.UAE University ability of ScienceDepartment of BiologyPrinciples of Environmental ScienceDone by Shaikha Mohammed.ID 201003128.Instructor Dr. Tarek Youssef.
