...Water Pollution Source: International Journal of Academic Research Kendall Frazier It is well known that water pollution is an issue beginning to receive more attention recently. Discharging into the rivers, discharging of sewage of fish growing fields are major sources of pollution. Water they say is life, and indeed they were right. With about 70% of the earth’s cover being water, it undeniably becomes one of our greatest resources. Since rivers constitute main sources of fresh water used in agriculture, drinking, and industrial applications, everything that causes the water pollution can be considered as an important issue to be studied. Modern times has increasingly encountered by various types of pollutions and their negative consequences including water pollution, which results mainly from sewages produced by industrial units, homes and agricultural activities. Pollution of water occurs when substances that will modify the water in negative fashion are discharged in it. This discharge of pollutants can be direct as well as indirect. Inorganic matters occurring in stones and soil, along with the amount of rainfall, river slope, temperature changes and trees and plant concentration in an area constitute amino factors to control water consumption in a workshop. It is therefore necessary to take a variety of problems as well as quantity and quality of the river water into consideration as well as the region’s needs for agricultural, energy production and transportation...

...Hillary Ogutu Honors Environmental Mr. Sup October 3, 20113 Water Pollution All around the world countries are fighting to keep their water clean. Whether it’s streams, rivers, lakes, or the oceans, countries have taken greater measures to maintain a high quality of water for both human consumption and as a key component to the environment. We deal with the pollution problems and then decide on ways to clean it up. This valuable resource is the key to survival; both plants and animals depend on water for their growth so it must be kept clean. The major contributors to water pollution can be classified into two categories, industrial and agricultural. What is water pollution? “It is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks uses or lives in it. “ Water covers up 70% of the Earth’s surface and makes up over 60% of the human body. Water pollution affects marine, ecosystems, wildlife health and human well being. Some of the major contributors that lead to water pollution come from industrial and agricultural. Industry is the highest source of pollution in the United States, causing for more than half of the volume of all the water pollution and also for the most deadly pollutants. Many of the industrial facilities use freshwater to carry away waste from the plant and into rivers, lakes and oceans. The industrial contains pollutants like asbestos, phosphates, mercury...

...WATER POLLUTION Effects of water pollution Contaminated Drinking Water. The risks of your health being negatively impacted by polluted drinking water in a developed country is small in comparison with developing countries. However, it is possible to become ill from contaminated water. When you are out hiking, you can acquire giardiasis that can lead to the presentation of acute symptoms like vomiting and intense nausea. This infection is caused by drinking water that has been fouled by animal wastes in untreated waterways. In anthropogenic environments like cities and towns, the potential toxins are far more numerous. Mercury Level Risks . Health risks from pollution vary from area to area. One of the most pervasive non-localized water pollution issues facing the world today is the level of mercury in the oceans. Inorganic mercury is a common byproduct of a number of industrial processes. The level of mercury in fish is mostly dangerous for small children and women who might become pregnant, are pregnant or are nursing. Mercury has been found to interfere with the development of the central nervous system in fetuses and young children, which could potentially lead to a large amount of long-term side effects. Health Effects of Toxic Runoff . In Louisiana, water quality can be so bad in many waterways that fish advisories are often posted to warn people against eating fish out of contaminated waterways. This is largely due to industrial runoff from localized sources and the...

...Environmental problem: Water pollution Nowadays in our world there have many environmental problems happening and almost of them haven’t been solved yet and still have an effect until nowadays. The one of interesting environmental problem is water pollution. Water covers over 70% of the Earth’s surface. Water is usually important and necessary for humans and animals life. We can’t deny that everyone needs water in order to be alive but nowadays many countries in our world have problems of water pollution. Water pollution occurs when the pollutants contaminate to water bodies. The pollutants are discharged directly or indirectly to water bodies and it is often that the pollutants get into water mainly by human causes. The contaminated drinking water can be as a contributor to wide range of health problems in humans and have negative impacts on wild animals and the environment as a whole. According to a report released by the advocacy group environmental Missouri, there were more than 12.7 million pounds of toxic chemicals, such as nitrates, arsenic, benzene and mercury were dumped into the Mississippi River in 2010. And another data from the U.S. Environmental Protection Agency, only the Ohio River, with 32 million pounds, received more toxic discharge in 2010 (Bernhard, 2012). "Missouri's waterways are a polluter's paradise right now," said Sarah MacFarland, state field associate for Environment Missouri. "These toxic chemicals end up contaminating our drinking water and are absorbed...

...Running Head: EFFECTS OF WATER POLLUTION Effects of Water Pollution Alexandra Garcia Miami Dade College Kendall Campus 1 EFFECTS OF WATER POLLUTION 2 Effects of Water Pollution Industrial development and production in western first-world countries has long ago reached the level when it is able to dramatically affect the environment. Among such industryrelated problems as air pollution, soil contamination, radioactive waste, and so on, the problem of low-quality water stands as one of the first places in terms of its importance for the survival of humankind. Therefore, information about the negative effects of water pollution should be not only studied, but spread among the general populous, taken into consideration, and prevented. One of the biggest problems connected to poor water quality is that entire food chains are drastically affected or even become extinct because of increased toxicity. Such pollutants as lead or cadmium get into water, and contaminate microorganisms living in it. These microorganisms are consumed by bigger species – such as plankton – which, in its turn, is eaten by even larger animals, and so on. Eventually, this chain leads to human beings, because people all over the world consume fish and seafood. Thus, by polluting oceans people worsen their overall wellbeing. Another problem connected to the contamination of water is the disruption of entire ecosystems. An ecosystem is the way of interaction between creatures that inhabit...

... May 22, 2016 was earth day around the world and was celebrated in ways of cleansing the earth. On this windy cool afternoon in Brooklyn, NY, the Gowanus Canal got a visit from the staff and students from St. Francis college. They were also trailed by a few local residents, this group of earth day goers went about the pollution within the country dirtiest waterway. They all gathered around on the bridge above the canal and said individual prayers. They said that everyone complain about the canal but no one is cleaning. So they saw no harm in asking god to bless the polluted canal. 2. What else is known about the topic? What other research is out there. Issues have two sides, present both of them. Something else that is fascinating about this topic is that there was a $500 million project set up by the city to clean up the canal but the project is moving slower than a snail on the run. The canal also empties into the New York Harbor. 3. What are the essential facts? The essential facts about this topic is that the politicians that promise so much before they enter office is not doing about this canal that is in the middle if there city and is pollution you can see with your eyes. Another fact is that this group of earth day believers had enough faith in their prayers sent to god. 4. What are the major ethical issues and concerns? (as it applies to the general public, to taxpayers, to the government or to the nonhuman organisms living in the...

...Essay on Water Pollution Water pollution has become an issue of great concern in our society. Many of today’s water ecosystems and drinking water are being polluted and destroyed as we speak. There are many types of water ecosystems such as oceans, rivers, lakes, and ponds witch provide homes to many different organisms. There are overwhelming factors that contribute to the problems of water pollution such as sewage, radioactive wastes, improper disposal of trash on land, and careless beachgoers. These are all significant problems that people do not realize until all of the damage is done. There are very few methods of controlling this pollution and more need to be developed in order to try and control these problems immediately. The first few causes of water pollution include sewage and nutrients from fertilizers being dumped into water. This causes a problem for all the organisms because the nutrients cause the algae and water plants to grow to abnormally large sizes. This can eventually block waterways. As the wastes decompose it uses up oxygen and blocks the flow of water in natural rivers and streams. Also, as these nutrients decompose in the water, they use up oxygen which can harm all the organisms living in the environment. Fish and other organisms living in water need oxygen just as much as humans need it. Since all aquatic organisms depend on oxygen in the water, without a sufficient supply they will not be able to survive. This would be a very dangerous thing. Anything...

...opportunities. It is prone to severe natural disasters such as cyclones, storm surges, floods, erosion, soil salinity etc. In combination with other natural hazards various forms of man made pollution made the coastal dwellers very vulnerable and ultimately slowed down their socio-economic development. This study will seek to analyze the vulnerabilities and risk of coastal water and suggest adopting appropriate measures for mitigation and management of coastal environmental pollution to the extent of generating environmental awareness among people. The coastal region gets polluted as the pollutants are carried through different rivers and canals to the sea. Water channels are used for dumping industrial wastes that ultimately end up in the sea. There is no facility for waste treatment in densely populated urban areas. As a result, water pollution is increasing. About three thousand ships including oil tankers come to our ports every year. There are several thousand mechanized trawlers and boats that spill oil. Sea is also polluted by oil spill because of accidents in ships. The authority fails to check pollution as they have no receiving or collecting vessels to face the emergency situation during oil spillage. Even our Port Authority has no laboratory to measure the extent of the pollution. Foreign and local ships find the Chittagong Port and its outer anchorage a safe dumping area for their waste, taking advantage of poor laws and their lax implementation due to logistic support...

Florida’s water pollution problem is a matter of public health and the public must be protected. According to Florida’s Department of Environmental Protecting report, found that half the state’s rivers and more than half of its lakes had poor water quality. Water pollution has many different causes and this is one of the reasons why is it so difficult to solve. High levels of sewage, manure, and fertilizer, when put in the water cause a toxic algae and red tide that contaminates drinking water. Everyday waste water from sinks, dishwashers, and toilets flow into the sewer pipes to a treatment plant and then...

...Hanoi, Vietnam is Facing the Threats from Water Pollution With the rapid growth of industrialization in urban cities, the water around them is getting more and more polluted. One time I casually crossed by To Lich River, one of the big rivers in the capital Hanoi, behind the industrial zone. The river water there was polluted seriously and smelt really fetid. A lot of small fishes and other sea creatures were dead and floating on the surface of the river. I was thinking about how people could live near such a polluted environment and eat those poison fishes. They might be in danger. I then stopped thinking and went away because that smell made me nauseated. That was the ordeal. However, the rapid growth of industrialization is not the only cause that leads to water pollution in Hanoi; climate changes and using old-dated technology to treat water also impact significantly on the quality of water. Water pollution has left huge problems in Hanoi. Above all, it affects heath negatively because the polluted water sources may produce an increase in disease such as respiratory diseases, water-borne diseases and intestinal sickness among people who live near that polluted environment. Yet, it also affects other economic activities such as agriculture, aquatic sports, fishery and tourism; and threatens the ecosystem. If water pollution gets more serious in the future, it is going to affect the development of economy and society. So, my motivation for doing this research...

...Air and Water Pollution Dimetrious Jones ENV/100 October 24, 2012 Katherine Fiegel Air and Water Pollution The two major elements that are essential to the survival of any living organism are clean water and air. Pollution is a major threat to these elements which in turn has made water and air pollution serious problems that are endangering the lives of people worldwide. Pollution is caused by contaminants being introduced into an environment which have very harmful effects on the environment as a whole. Most of the pollution that ends up in the environment is a result of human actions, but there are some instances were pollution is caused by natural disasters. Pollution can have a very devastating effect on virtually every living organism within any environment that has become contaminated with pollutants. Primary and Secondary Air Pollutants Most forms of air pollutants fall into two major categories which are primary and secondary. Primary air pollutants are those that are emitted directly form a source, this could be the smoke from the exhaust pipe of a car or the gases emitted from the burning of coal (www.greenfacts.org). Secondary air pollutants are those that are not emitted directly but are formed by the interaction of primary pollutants with the atmosphere (www.greenfacts.org). Sulphur dioxide (S02) is a primary air pollutant that occurs most often when coal is burned in thermal energy plants. Sulphur dioxide is one form of air pollution among others...

Cartoon commenting on polluted condition of the Thames. Punch, 10 July 1858. Source: Wikimedia Commons • The growth of the major industrial cities also caused water pollution. All too often, rivers that pass through urban areas became a receptacle for human waste products, both domestic and industrial. Sewage, as in most cities, was washed out into the streets where it found its way to the rivers with disastrous consequences. • In the first half of the 18th century, both London and Paris, the largest cities in Europe with respectively 1 and 2.4 million inhabitants by 1850, experienced a series of recurring epidemics of cholera and typhoid. In 1832 over 20,000 Parisians died in a cholera outbreak; London experienced similar outbreaks. This was caused by increasing amounts of sewage dumped into the Seine and Thames rivers. • London was one of the first cities in the world to build a sewer system and improve the quality of its drinking water supply. The London Board of Health eliminated cesspools in the late 1840s, and a Metropolis Water Act of 1852 forced water companies to move their intakes upstream and regulate their...

...Mozambique water threat Carolina Narciso Pedro , has studied the experiment water pollution of Mozambique, which is a developing country where the majority of the population still lacks access to safe drinking water. The experiment includes the incidence of cyanobacteria and the production of microcystins (toxic peptides) in three different drinking water systems in Mozambique and established methods for monitoring cyanotoxins in watercourses. The main source of water pollution is effluent from households, agriculture and industry, but the growing interest in exploiting natural gas, metals and other resources in the coastal areas of the country is also increasing the risk of polluted drinking water. change in global climate is equally responsible: Higher temperature causes runoff of water nutrients resulting in cyan bacteria’s strengthening. Cyanobacterial blooms in freshwaters represent a major ecological and human health problem. It has been estimated that 25 to 75% of cyanobacterial blooms are toxic. Production of cyanobacterial toxins (cyanotoxins) includes human and animal health hazards, which can present risks of illness and mortality at environmentally relevant concentrations Cyano bacteria, also known as blue-green algae, are a family of single-celled algae that proliferate in water bodies such as ponds, lakes, reservoirs, and slow-moving streams when the water is warm and nutrients are available. Many cyanobacteria species produce a group of toxins known as microcystins...
