Oil Pollution in water
Petroleum is a naturally occurring mixture of organic chemicals, the most abundant of which are hydrocarbons (Gale, 2014). Petroleum is a natural may exist in gaseous, liquid, or near-solid phases either alone or in combination (Encyclopedia Britannica, 2013). The liquid phase is commonly called crude oil, while the more solid phase may be called bitumen, tar, pitch, or asphalt (Encyclopedia Britannica, 2013). There are many types of petroleum ranging from gaseous methane with only 16 g/mole, to very complex substances weighing more than 20 000 g/mole (Gale, 2008). Some crude oils are thick and viscous, while others are light and unstable (Gale, 2008).
Oil is one of the most common water pollutants in the world, primarily because of how much is used on a daily basis (National Research Council, 2014). Spills, leaks and improper disposal lead to oil seeping into our water supply and contaminating it. According to Gale (2008), Oil spills are created by the accidental or intentional release of crude oil (petroleum). When spilled into rivers, streams, or marine environments, oil can damage ecosystems far from the original spill areas. Even though the oil spill is cleaned and the water is decontaminated, the petroleum leaves behind residues of relatively heavy molecules that are more persistent in terrestrial or aquatic habitats, and cause longer-lasting effects. In addition to cost to repair and clean, oil spills can result to economic lost and long term economic damage to the affected areas.

...synthetic petroleum base oils on the market today. The plant base oil is not only from a renewable source, it is biodegradable and completely nontoxic. Additionally, motor oils and other lubricants formulated from our products can be dropped into existing motors and equipment without any modification, and can seamlessly fit into the existing recycling streams and collection infrastructures once used.
Future Research
A better monitoring and research should be to measure how much oil is really entering our waters, how much of it is coming from each source and the effects of it in the environment. Also, an in-depth research on oil pollution in deeper waters and oil production in offshore is needed to full understand the nature of the problem. Last and most importantly educate the public so that they are aware of the harmful effects of crude oil in the environment.
The British Petroleum (BP) oil spill in the Gulf of Mexico was one of the worst ecological catastrophes in human history, causing vast damage to a fragile and beautiful ecosystem while at the same time calling attention to the deficits in current approaches to energy prospecting, risk management, and cleanup. This analysis of the Deepwater Horizon explosion and oil spill will devote attention to the following questions: (a) What kind of technology is in use for deep-sea oil extraction, what are the factors that accounted for the BP catastrophe, what were the statistical components of the spill in terms of volume and concentration, and what was the spatio-temporal scale of the oil spill? (b) What were the environmental (physical, biological, hydrological, and atmospheric) impacts of the oil spill, in addition to the economic and social impacts? (c) What were the scientific, technological, and policy solutions implemented by various actors to pursue the cleanup of coastal areas, wildlife, and wetlands damaged by the oil spill? (d) What is the feasibility of long-term biodiversity conservation measures and the limits of such solutions?
Oil provides us with many necessities in our lives. Cosmetics, medicines, cleaning products, asphalt, food, plastic, and most importantly, petroleum. But of course, nothing comes without a price. The oil that makes our lives so much more convenient, is also ironically gradually killing the environment, this very Earth that we live in. One of the biggest environmental concerns come from oil spills. Oil spill is defined as “ the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution.” Let’s look at some examples of these oil spills.
Last year, news spread of an oil spill off the Gulf Coast. These events occur periodically and usually register much media attention. As British Petroleum (BP) executives could not shut off the crude oil or prevent the damage it caused, people took notice. Millions of dollars in tourism, commerce and sales were lost. Thousands of wildlife acres and ecosystems were also compromised. There were more questions than answers.
In 2010, there was a huge oil spill near the Gulf of Mexico that we now know as the BP Oil Spill today. The Spill sent about 170 million barrels of crude oil into the Gulf of Mexico. The spill killed 11 men aboard the deep-water Horizon. The BP Oil Spill impacted the environment very negatively. There were different types of environmental impact as a result of the Oil Spill, but the two that grabbed my attention the most are the Polluted Air and the Contaminated Food Chain. The first impact that grabbed my attention was the Polluted Air. Because of the Oil Spill, the air around the surroundings neighborhoods was polluted. All the lightest chemicals in the oil that had spill evaporated within hours of the incidence forming air pollution particles. These particles that are in the air poses significant threats to the human health from being inhaled. The chemical found in the particles that was formed is known as Volatile, which has been known to cause respiratory irritation and central nervous system depression (Solomon & Janssen, 2010). The second impact that grabbed my attention was the contamination of the food chain, specifically the food chain of sea animals that lives near the Gulf of Mexico. Scientists found traces of oil in zooplanktons; this could only mean that the sea creature has had contact with the spilled oil. According to the Staff at Houston Business Journal (2012), “Baby fish and shrimp feed on the tiny, drifting zooplankton, and then introduce contamination and pollution to the larger sea creatures in the food web.” With these findings, it isn’t going to take long before the baby fishes become grown and caught by fishermen and before we know it, it’s on our dinner plate. And here we are eating fishes w...

Offshore oil drilling has had so many issues recently. It is time to put a stop to it before we completely poison our oceans. So much environmental damage has occurred from this act. The actions being Many people do not support it and think that we need to protect our oceans.
Clean water involves seclusion of lakes and hoping the acid rain does not reach these pure water supplies. Another major source of contaminating clean water are oil spills and how destructively they blanket the shoreline they come in contact with. Although offshore drilling expeditions contribute some to the devastating outcome, oil tankers are the superior enemies toward the water. One estimate is that for every one million tons of petroleum shipped one ton is spilled. The largest super tanker spill was in 1979 when 3.3 million barrels was spilled off the coast of France. The largest in the United States was the Exxon Valdez in the gulf of Alaska. On the night of March 24, 1989 the 987 foot Exxon Valdez ran aground in the gulf of Alaska spilling 260,000 barrels of oil. With the help of the forceful winds, the slick soon covered about 1,100 miles of shoreline, including many islands in the sound.
Once extracted from the earth, crude oil must be refined to become useful. Crude oil contains over 500 hundred hydrocarbons plus many other elements and additives that are all combined into one product. The refining process separates and groups these hydrocarbons together to make things that are of value to us such as gasoline and diesel fuel, waxes, asphalts, household fuel oil, industrial lubricating oils, greases and other petrochemicals.
Because it is the most highly publicized of the different forms of ocean pollution, oil spills, oil leakages, and general oil contamination are something that we all seem to be aware of. Since the Exxon Valdez incident, the American public in particular has been more and more critical of oil companies.Each year, over 700 million gallons of oil end up in the ocean. Contrary to what you may have thought, most oil pollution doesn't come from tanker accidents. In fact, tanker accidents account for less than 90 million of the g...
Most people believe that one man-made natural disaster would teach us to be better, but we have learned that history repeats itself. The Exxon Valdez oil spill (in 1989) and the Deepwater Horizon oil spill, or BP oil spill, (in 2010) were both devastating oil spills that shocked the nation. The Exxon Valdez oil spill occurred due to a tanker grounding. The BP oil spill was caused by an explosion on the Deepwater Horizon oil platform. These two oil spills were both disasters and had greater effects in certain categories. In this essay, I will be comparing the cause of both oil spills, the damage/effect of both oil spills, and the cleanup of each oil spill.
This paper describes equipment and techniques for responding to oil spills. Various techniques for the containment, cleanup and recovery of oil spills are examined; advantages and disadvantages of each are considered. Along with providing insight for oil spill response, this paper discusses environmental factors which can contribute to the success or failure of a cleanup operation.
The Gulf of Mexico oil spill has had an extremely negative effect on the surrounding wildlife and ecosystem. The oil spread across the gulf contaminating any living organism that came into direct or indirect contact with it. The oil cuts off the ability of oxygen from the air to move into the water which directly harms fish and other marine wildlife that require that oxygen. The dispersant that the BP is using to try and break up the oil moves the slick into the entire water column which contaminates the ocean floor which would most likely not have seen any damage if it wasn’t for the use of these dispersants. More than 400 species that live in the Gulf Islands and marshlands are at risk and as of November 2 s...
This oil as it moved through the water killed 300,000 sea birds, 2,600 sea otters, 300 harbor seals, and perhaps millions and millions of fish. Of the 23 studied species hurt by the spill only 2 are said to be completely recovered. The 2 are the Bald Eagle and the River Otter. Some show no recovery at all. Of these that haven’t recovered at all are the Harbor Seal, Harlequin Ducks, Pacific Herring, Cormorants, and even certain whales. If people were familiar with some of the clean up that went on, they would probably remember that cleaning of all those ducks. Well I hate to tell you but it was useless. Some of them died 5 days after they were released.

The oil refinery converts crude oil into valuable products and supplies. These products are made and sent to many countries abroad, in which are transported on land or along rivers and canals. Crude oil is then arranged and categorized into segments by fractional distillation. Raw crude oil, or unprocessed crude oil, is not normally beneficial in most industrial applications. Low sulfur crude oil has been valuable as a burner fuel to construct steam for the force of seagoing vessels. The lighter elements have the ability to construct explosive and dangerous vapors in the gas tanks. There are extremely hazardous, and are often used in war ships. The remaining hydrocarbon molecules are filtered from crude oil and used towards lubricants, feedstock, plastics, and fuels.
