Water Pollution Effects On Aquatic Life

Improved Essays
Literature Review There are endless ways the environment is being affected globally. There are drastic changes occurring all over the world, from deforestation to excessive water pollution. One urgent issue facing the world today is freshwater pollution and the negative effects it is having on freshwater aquatic life. Pollution is creating a positive feedback loop in our freshwater aquatic life, including the killings of many of freshwater wildlife. Through the analysis of several different articles and books, this review will look over how eutrophication, acid rain, and heavy metal pollution effects freshwater aquatic life.

There have been more than enough scientific evidence proving this problem is prevalent today. Eutrophication, the process in which excess fertilizers and other materials runoff into lakes and ponds, creating algal blooms, which sucks up the oxygen, killing fish and other organisms which is crucial to the freshwater environment. Acid rain is a type of pollutant which has impacted the southern Appalachian Mountains. Acid rain is a level four on the pH level which measures the amount of hydrogen in a substance. This pollutant falls into our freshwater ecosystems, and kills many of the living organisms due to the high acidity in the water. Heavy metals are extremely dangerous and causes a multitude of problems for our freshwater. Lead, Arsenic, and Nickel, are a few of many types of heavy metals which can cause mutagenic changes, and death in the freshwater organisms. All these types of pollution are an increasing problem in our freshwater ecosystems that are hurting our freshwater wildlife. The Environmental Protection Agency is trying to decrease pollution, and the type of hurtful, toxic, and dangerous materials are that going into our

    Salt not only pollutes the water, but damages the ecosystems because the Great Lakes are freshwater sources and the Atlantic Ocean is full of saltwater; more salt will eventually decrease our freshwater sources. Salt affects water’s density, reduces oxygen circulation within water [4], and is harmful to aquatic animals, like it is to humans and other land animals. Because of this, sewage treatment plants and water treatment facilities have to filter out salt and other contaminants from used water before sending it back to water…

    elsewhere is absorbed by our oceans. Ocean acidification is caused by just that, the quarter of carbon dioxide that still remains from our atmosphere being taken in by the ocean’s surface layer. When carbon dioxide that hits the ocean’s surface layer combines with seawater, some of the carbon dioxide reacts with the water to from carbonic acid. Carbonic acid separates into hydrogen ions and bicarbonate ions. Then, hydrogen ions combines with carbonate ions forming more bicarbonate ions which makes seawater more acidic.…

    Water, something people can’t live without with. However, water quality has always been an issue in Canada. People may not really notice it since in households, people can drink the water from the hose, or by boiling it if they are concerned about it. For example, due to population increase, it increases the demands for agriculture, manufacturing, energy and transportation. This also leads to pollution of chemicals into rivers and lakes in Canada.…

    The main chemicals causing poisoning of wildlife are herbicides and pesticides from garden and park run off. Sewage out fall can cause excessively high nutrient levels and pathogens that can be harmful to all marine life. An excess of nutrients may cause, toxic algal blooms or extreme plant growth that will affect the amount of dissolved oxygen when they die. With the increase of the urban areas near the coast the more likely it is that rubbish will be dumped or blown into the estuaries which may cause organisms to suffocate. Many construction sites will cause sediment build up in the habitat, the sediment can decrease water quality, reduce light penetration in the water and restrict bottom dwelling plants and…

    The water quality of the U-High Creek was identified as excellent, but not all bodies of water have excellent water quality. Humans can pollute water in many ways, and make it unsuitable for organisms living in the water. One way humans can pollute water is when farmers put pesticides and fertilizers on their crops, which contain harmful chemicals like phosphates and Nitrates. When it rains, the pesticides get washed away through the soil and end up in rivers, streams, and creeks, therefore polluting that body of water. If large amounts of pesticides and fertilizers end up in these bodies of water, the amount of these harmful chemicals grows substantially.…

    The Great Lakes hold 21% of our natural freshwater supply. I am a limnologist living in Detroit, Michigan. My city is located near Lake Erie and I visit it weekly with my research team to record the changes in the lakes. I've written two books: one about Lake Erie and the other about Lake Huron. Many believe that The Great Lakes are dying; as an expert and an experienced scientist, I can confirm that this is true mostly because of pollution, habitat loss, and non-native species entering the lakes.…

    Animals such as sharks and whales rely on water to survive. If the water that these sea animals need to survive is polluted then they will not thrive and will ultimately die. When water is polluted with various types of garbage and chemicals, the fish and other seas either get caught in some of the trash or digest some of it. Sea animals are notorious for getting caught in the plastic that is used to hold cans of pop, thus trapping them limiting them from being able to eat anything. That can lead to plenty of deaths to fish and plenty other animals that live in seas.…

    Many species in the world are endangered and eventually becoming extinct. The main problem that generates extinction is human activity; people cause extinction every day and unknowingly to them, it is killing innocent animals. Due to pollution, natural forces, human interaction, and loss of habitats, animal extinction is a major crisis in the world; people are the only ones that can save the animal population before it is too late. Pollution is among the most insidious threats to animal extinction. It can be as obvious as sewage and oil spills in water or as invisible as chemicals used every day.…

    Eutrophication Lab Report

    Introduction Eutrophication is a condition in an aquatic ecosystem where high nutrient concentrations stimulate blooms of algae (e.g., phytoplankton). Eutrophication is a natural process that occurs to all lakes over time as the weathering of rocks and soils from the surrounding area that leads to an accumulation of nutrients in the water. It can also be caused by run-offs of fertilisers. Three of the key components of modern fertilisers are nitrogen, phosphorous and potassium. After a rainy season these nutrients that were not absorbed, run off into waterways such as dams, lakes, rivers, streams, ponds and even sometimes swimming pools.…
