Eutrophication Essays

conditions were good, warm and sunny. A series of tests were done to determine water quality. One test conducted was the measure of nitrate in the water. If there is too much nitrate it grows algae which is then eaten by bacteria, and can cause Eutrophication. Another test was done to determine the amount of BOD, which shows how much dissolved oxygen is needed by Aerobic bacteria in order to break down material. Ph is responsible for how acidic or basic the water is. If a body of water has a high ph

-1504A -07) Instructor: Trena Woolridge Unit 4- Discussion Board Amanda Kranning October 27, 2015 Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.(Cloern, Krantz, & Hogan, 2013) Eutrophication forms when an abundance of nitrogen and phosphorus increases growth within an environment. One issue found

Yasmin Givens Introduction The purpose of this experiment is to investigate the effects and results of agricultural runoff, as well as how varying types of fertilizer (conventional and time-released) may affect the ever-growing problem of eutrophication. If the conditions of agricultural runoff are simulated, then the algae will grow plentifully and consequently kill the other life in the water. If the different types of fertilizer are tested (conventional and time released), then the time released

The third test we conducted were eutrophication tests, phosphate and nitrate tests, and acidity and alkalinity tests. The first one was a ph meter test to see if the water in the creek was acidic, neutral, or alkaline. On the ph meter we got a 7 which is neutral, and that’s good. For the alkalinity

• Duckweed (Lemna minor) is a member of the Lemnaceae family (Monette et al. 2006) it is a small plant that floats on the surface of still or stagnant water that is usually rich in nutrients (Keddy 2010). It was seen that Duckweed thrived in areas of high nutrient content, high sunlight and warmer temperatures (Taylor 2011) .It was also seen that fertilisers contained nutrients, such as nitrates, which greatly influences duckweed growth. Duckweed is also used for feed for farm animal, such as ducks

Identify the problem: In a vast array of Michigan lakes, a crusty brown algae is spoiling the waters it comes into contact with. (Some lakes include Torch Lake, Elk Lake, and Lake Charlevoix). Pinpoint Causes of the Problem: From an undetermined source, groundwater nutrients nutrients like nitrogen and phosphorus are penetrating the lake at abnormal levels. However, a few leads have been suspected. These culprits include invasive mussels, heavy ice cover the last two years, residential and agricultural

environment follows up. This has caused the loss of profits in tourist industry and increased the cost of fresh clean water in China. One of the most severe problem caused by agriculture goes towards the environment and human society is eutrophication. Eutrophication describes the situation of excessive richness of nutrients in water body, which mainly caused by human activities. Due to the fact that environmental

Introduction: The Everglades is a national park that protects numerous of species and endangered species, for example, the Florida manatee, American crocodile, and Florida panther. According to Everglades foundation.Org, the Florida Everglades is the largest subtropical wetland in the United States, an international biosphere Reserve, and home to 73 threatened species are endangered species. The Everglades flows from the bottom of Orlando through Lake Okeechobee South to the tip of Florida Peninsula

My goal is to decrease the amount of nitrates in river systems. Explain the science of the problem that is created by the indicator. Eutrophication Eutrophication is a process that occurs as a result of this indicator. When farmers use fertilizers with nitrates on their crops, the rain washes the nitrates into the river. This excessive amount of nutrients causes the plants to grow rapidly. Now that these plants have grown so large, they block the sunlight. The underwater plants are deprived of

This lab uses a lake simulation to study how the addition of nutrients and toxins can affect the lake, its inhabitants and the surrounding area. There is a strong focus on the addition of Phosphorous and added toxins because both are key elements in growth in lakes. The Virtual lake includes these five simulated species; green algae, cyanobacteria, bosmina, daphnia, and trout. There are two types of phytoplankton in the lake model, green algae and cyanobacteria. Green algae are a very diverse group

Using Daphnia to Detect Water Safety Due Date: Monday, the 31th of October, 2017 INTRODUCTION Question: Can Daphnia be used to detect water pollution? How does the water type (source) affect the number of Daphnia and the accuracy and efficiency of testing water safety? Purpose: The purpose of this project is to test different water sources for safety using the Daphnia species. This is important to the local people of Santa Barbara because it can be used to test whether the water & soil sources

Introduction Our aim of this experiment is to determine how eutrophication affects the growth of duckweed by adding different concentrations of fertilizers to the water with different types and forms of fertilizer keeping it in set conditions for a period of two months to observe how eutrophication affects the growth of duckweed. Thus our hypothesis for this aim is that it is expected that eutrophication would affect the growth of duckweed when different concentrations of fertilizers are added to

The purpose of this experiment was to test how fertilizer impacts the growth of microorganisms of Susan’s Swamp, by measuring the amount of microorganisms found in each sample. I was looking for moving microorganisms because it was difficult to distinguish between the fertilizer and the microorganisms. According to Good and Beatty nitrogen is found in fertilizer and when the nitrogen is added to the aquatic ecosystem it will cause a flourishing of microbial growth, which can result in a “dead zone”

The problem with Lake Erie is that it is infested with this toxic algae making it hard for the people of Toledo to drink it. The causes of the bacteria didn’t start in Toledo. It stated hundreds of miles from Toledo. The algae are fed by natural and commercial fertilizers from the watersheds, farms, livestocks, and city sewers. All of the waste from those sources form in the shallowest part of Lake Erie, and when the water warms the bacteria spreads. Other areas around Lake Erie are already experiencing

While the hazards of excreting toxic chemicals into our world’s ecosystem through municipal sewer systems are widely known, most people are not aware of the dangers of one silent source: estrogen. After a seven-year effort, lead researcher Karen Kidd and her primary team of biologists found that even trace amounts of estrogen present in these wastewater systems can have disastrous impacts on wild fish populations as it completely diminishes their capacity to reproduce and produce viable offspring

Aquatic toxicity refers to how certain compounds interact with organisms in marine ecosystems. Human activities such as agriculture often require the use various compounds; many of these compounds, however, flow into rivers, lakes, and other bodies of water via surface runoff. The compounds that we investigated in this experiment were atrazine (Figure 1), an herbicide that kills broadleaf and grassy weeds, and metalaxyl (Figure 2), a fungicide that kills oomycetes and water-mold fungi. Although

The hypothesis stated the further away the water source is from civilization, the less unnatural ions there will be present in it.. The reference table shows that only phosphate and chlorine is present in the sample. In the reference table the results show that the liquid in the sample test tube did not change color in the sample test tube with the ion samples of calcium and iron III. The significance of making the Results from the Test Tubes Displaying the Observations from the Lab reference table

BYE BYE GREAT LAKES I am Dr. Hannah Romanik from Chicago, Illinois. I am a scientist studying the topic of the Great Lakes’ health. Pollution, invasive species, and habitat loss are issues facing the Great Lakes and places around it. Clearly, pollution is still a huge problem facing the Great Lakes ecosystem. Chemicals from agricultural uses get in the lakes. The fish digest the chemicals; we catch and eat the fish. Therefore, we have the toxins in our body and eventually die. Also, cleaning

On the trip with SWEEP the health of the Susquehanna River was studied. In order to do that, chemical test, biological tests, and physical observations were made. Chemical testing showed the more scientific side of water quality, such as the amount of nitrates, phosphates, the pH values, temperature, dissolved oxygen, and turbidity. Searching for macroinvertebrates was the biological testing. Certain macroinvertebrates and the quantity found determines how healthy the stream is. Physical observations

known that eutrophication occurs when excess nutrients are added to a body of water and primary productivity is increased. However, the scientific paper, Aquatic eutrophication promotes pathogenic infection in amphibians, puts a direct focus on a specific parasite, Ribeiroia ondatra, and seeks to give evidence that the onset of eutrophication is the driving factor allowing the parasite to disrupt amphibian development. The authors set-out with the goal to provide evidence that eutrophication leads to
