Water samples from the Clark Fork have been taken and will be tested using both absorption and emissions spectroscopy in order to check the levels of group IA and IIA metal ions. When electrons in an element are excited energy is released that can be measured as light. Each element releases different levels of energy that are observed as different wavelengths of light. With the proper equations (E=hv and E=hc/⋋), emission spectroscopy can be used to find the wavelength and frequency of light emitted by the excited electrons. This will help determine the types of ions present in the water sample.
The by-catch and pollution must also be monitored. There have been positive results from this new management overall, though many salmon populations as well as other marine populations continue to be in decline. It is important that we as consumers choose fish products from sustainable fisheries and understand what this means for marine environments. If salmon continue to be fished and farmed in ways that are damaging to the environment, collapse of the entire industry may occur. This can cause unforeseen economic and ecologic problems that may be irreversible.
Lastly, we got to witness and test the Law of Conservation of Mass through the reaction in this experiment. The list goes on, but these are just a few objectives from the recently conducted lab experiment. Background: Before this experiment we had knowledge on the safety of most of the materials we worked with. Copper (II) Sulfate is harmful by inhalation or ingestion. Iron (II) Sulfate is also harmful if ingested, and could cause death.
This, in turn, can affect habitat quality for plants and animals that live downstream. Biodiversity may be lost if aquatic plants and animals cannot tolerate changing water conditions. When large volumes of water are pumped from a stream or river, water chemistry can change significantly with a drop in water level. Temperatures may rise and oxygen levels may drop, affecting aquatic species that don't have a wide tolerance. Biodiversity may also be reduced if invasive species, such as the zebra mussel or golden algae, are introduced into a waterbody during the drilling process.
The disadvantage of building dams on the Mississippi is that it could cause flooding if there are too great amounts of water. The flow of major tributaries in places such as Missouri, Ohio and Tennessee has been controlled by a series of dams. A Levee in the Mississippi river is a naturally occurring ridge or artificially constructed wall which regulates water levels and stops the river from flooding. They are parallel to the course of the river in its floodplain. Advantages of levees are that they can protect a building from the surrounding area of the Mississippi and there will be no pressure from the water to cause structural damage to the building.
Each of these compounds is known to be poisonous, cancerous, or cause birth defects. The EPA fears that the drinking water will compromised due to runoff of the surface water discharge. Additionally, contamination of underground sources of drinking water and inadequate treatment of the waste water are possible. The threat of contaminated water supplies can cause a fearful population, largely due to the propaganda spread by anti-fracking initiatives. Although there are potential economical disadvantages to fracking, there are also enormous positives.
The whole committee and the government needs to get involved with trying to solve the problems. Having a set action plan for helping the solution. Having penalties for those who do not follow the rules to stop the pollution to the lake. Learning new methods to the help set problems straight. Getting involved with the other parts of the Great Lakes to make sure they do not go through the same problems.
Purpose: To Inform Specific Purpose: The audience should understand why the Clarence J Brown Reservoir is a good thing but it also has its bad. Central Idea: Through all the research I have learned that even though the reservoir is a good place there could be hidden dangers. Introduction 1} Flood control, camping, fishing, hunting, swimming, and wildlife reserve all of these things are things you think of when you here Clarence J Brown Reservoir. 2} After reading numerous reports from the State Parks Natural Resources I realize there are hidden dangers such as lead, mercury, and ecolie. 3} Internal Review A} There are several
Then the NYSDEC administered Rotenone, an aquatic pesticide that targets only fish. This process removed 220 Snakeheads from the lake and with further monitoring of the lake it tested negative for the pesticide. The NYSDEC has played a major part in saving other species that the Snakehead can potentially endanger. While the Snakehead was a guest in our New York waters it did not do a great amount of damage. The NYSDEC was extremely vigilant in ensuring that this species of fish did not take over, consume our native species of aquatic life as well as life on land and populate.
Unlike dry deposition, winds can blow wet deposition hundreds of miles away from the source of emission, making it an issue for everyone. Natural, unpolluted rainwater is slightly acidic, with a pH of around 5.6 due to a natural occurrence of CO2, NO and SO2 substances. Therefore a pH value less than 5.0 is considered to be acid rain. In certain areas of the United States, the pH of rainwater has been measured
