Prime concern for marine health life has created an instinct for undertaking this type of study by the authors. Grades 6 - 8 Do you agree with this alignment? Fill your washbasin halfway with water. Even though the quantity of the cotton balls is controlled, but the quality of the cotton balls is not tested. Have students compare their results for each material before and after the dispersants were added. Now, let us pay attention to your marine life bath toys. Is the dispersant a pollutant that upsets the ecosystem balance? Oil spills are detrimental to the health of marine environments and marine organisms. This condition is caused by the excess amount of nitrate that is then converted into nitrite by the digestive system.
Usually oil spills happen when ships carrying large oil tanks sink in the ocean, causing the oil to leak out of its containers and contaminate the ocean, killing thousands of marine lives. Place the sorbents small pieces of the paper towel onto the oil tank plastic cup 6. This was done using a pipette to remove the bottom layer of the solution and it was possible because the alcohol was not soluble in the water. This catastrophe killed wildlife and threatened the livelihoods of fishermen, restaurants, and oil industry workers resulting in massive job losses. A white cloudy ring has formed. The solid was formed in the mixture and the flask was shaken until it dissolved. Remove as much oil from the oil-and-water mixture.
This causes many animals and much of the coastline to be covered with a very sticky black layer of oil. Moreover, it is also called Internal-External Analysis. And if they did eat the oil, would the residue damage marine life? This is definitely the most oiled layer. To do this, we needed to understand a little about what makes a solution. This explains why oil is able to be unchanged while it is underground. Obtain exactly 50 mL of Formula 409, and slowly pour it from a height of 1 cm into the tub. Resources include online version of the Ocean Planet exhibition.
The oxygen molecule is incorporated into the oxidized hydrocarbons and monoxygeneses are generally involved. The desired temperature for the reaction was 150oC. To comprehend and learn about the factors that affects the boiling rate and the boiling point of water. Dispersants are also not effective since they break down the oil which later sinks down to the bottom of the ocean causing harm to the deep sea environment which is where many of marine life is found, it also uses chemicals that are harmful to the environment. Therefore there must be some resources and capabilities in an organization that can facilitate the competitive advantage to company. The Exxon Valdez the largest oil spill in history was carrying 1. The flash was rinsed with 15 mL dichloromethane and it was added to the separating funnel.
Words: 2392 - Pages: 10. Features include a section specifically designed for students who are doing a project on the spill, a comprehensive list of downloadable publications, and links to other related sites. The four sources that could be the point of contamination are a new subdivision, textile plant, an organic farm, and a mountain lake. Cleanup strategies include corralling and burning, skimming, absorbing, and dispersing oil. It can even lead to death in rare cases. Resources are also valuable if they provide customer satisfaction and increase customer value.
There were four infants affected by this cluster. The curves in part a i , a ii and a iii do have a flat section. Point out the issues of putting more chemicals in the water and if this is appropriate or not. Allow the oil to spread over the whole surface. Interactives Any interactives on this page can only be played while you are visiting our website. The Biological and Chemical Processes of Bioremediation 1. They discuss the effectiveness and flaws of oil cleanup strategies based on the results.
However, the problem should be concisely define in no more than a paragraph. Purpose The purpose of our lab was to reflux an isopentyl alcohol with carboxylic acid acetic acid , adding three drops of sulphuric acid acting as a catalyst to produce an ester isopentyl acetate and water. Turbidity indicates the amount of oil being broken down and becoming part of the water. Investigation 3 Hypothesis: The bacteria and fungus will brake down the oil in the dish but not as well as the previous two because of the sand interfering with the degradation. Is this an effective means for cleanup? One is duplicating that is direct imitation and the other one is substituting that is indirect imitation. Results: Observations: Pseudomonas Species Application Table 1 General Appearance Characteristic of oil Color of oil Turbidity of water Day 0 The oil forms a thin uniform layer across the surface of the Amber 0 Day 1 The oil is lighter in color and has begun to brake into tiny fragments. Gesture to point out the loop current and explain how the oil has been distributed throughout these regions by currents, waves, winds, and tides.
This is a great place to work! Have groups move to their assigned stations where materials are set out. What I would do differently is most likely try a new way to fix the oil and get it cleaned up, instead of using a spoon. Environmental Protection Agency have demonstrated that oil degradation by indigenous microflora on the beaches of Prince William Sound was accelerated by adding fertilizer directly to the surfaces of oil-contaminated beaches. Repeat steps 2 to 5 until you have removed as much oil as possible. I think that the Skimmer is the most efficient because it is able to recover most of the oil in a reasonable amount of time. But the ship had a limited amount of oil. Words: 1402 - Pages: 6.
Once all the needed chemicals were added we waited for about 70-75mintues for the reaction to take place. Regardless of the method used, cleaning up oil spilled on water is a very time-consuming and difficult task. The average spill size is around seven thousand metric tons Smets 1982. Then, using your fingers sprinkle a fine layer of fertilizer over the entire layer of oil. Who should pay for the cleanup? Also, through this experiment, students know some basic indexes to assess the efficiency of pumps used.
My paper will cover three elements of this horrible disaster: First, the ecological impact on life in the gulf after the spill, Second, the current economic life of the local communities, and lastly, what is being done to mitigate future consequences. Within days of when the organisms were applied to the spill changes in the oil can be seen. Equipment breaking down may cause an oil spill. Pour a spoonful of detergent into the third container. For example, using Aquafina in substitution of tap water, Pepsi in alternative of Coca Cola. It is fragmented and is cloudy in appearance Cloudy with a hint of yellow 0 Day 3 The oil is almost gone. The 1989, Exxon Valdez Oil Spill has been considered the most devastating, human-caused, environmental disaster ever to occur in history, especially towards the Nigerians, since they are still being affected by it.
