The jury is still out on the lasting economic and environmental effects of the BP oil spill. 1. Oceanic oil spills became a major environmental problem in the 1960s, chiefly as a result of intensified petroleum exploration and production on continental shelves and the use of supertankers capable of transporting more than 500,000 metric tons of oil. These effects can depend on what kind of oil was spilled and where (on land, in a river, or in the ocean). The oil residue also can disperse almost invisibly in the water or form a thick mousse with the water. Oil spills may occur all around us.

The impact of the spill on fish populations is still largely unknown, though the study of specific fish species indicates that there could be long-lasting effects for fish exposed to oil. Suffocation cause by oil spills and oil poisoning are among the first group. But an oil spill like Deepwater Horizon will add oil … Scientists noted that the prevailing paths of the Gulf of Mexico's Loop Current and a detached eddy located to the west kept much of the oil, which covered a sizable part of the gulf some three months after the accident, from reaching shore. Factors such as oil-biodegradation, ocean currents and response measures (dispersants, burning) reduced coastal oiling. The oils spread fast over a short time to cover vast expanses of the water body. Environmental Effects. Oil spills are harmful to marine birds and mammals as well as fish and shellfish. An oil spill can have a major impact on the economy in coastal areas. When oil is spilled or leaked into in waterways and the ocean, it spreads very quickly with the help of wind and currents. Examples of impacts to species included: up to 20 percent of all oceanic juvenile Kemp's Ridley sea turtles present during the Deepwater Horizon oil spill perished from oil exposure; and oil-associated health effects to Barataria Bay, Louisiana, bottlenosed dolphins reduced their survival and reproductive success in years following the spill, leading to a 50 percent decline in the population, according to … For example, oil can sink down through the sand on beaches into sediments, and can work its way down into the muddy bottoms of marshes and tidal flats. Oil may strand at the high tide line, leaving black lines or globs of oil on the beach as the tide recedes. On waterlogged sediments such as on mudflats, oil will remain on the mud surface if left undisturbed, and be lifted again on the next tide. Map depicting the effects of the Deepwater Horizon oil spill, caused by the explosion of an oil rig off the coast of Louisiana on April 20, 2010. Oil pollution has a detrimental effect on the ecosystem and its effect are usually very visible and sometimes very devastating.

Over time, oil waste weathers (deteriorates) and disi… One way is bioremediation, which is the use of microorganisms to break down pollutants. Oil spills in water may cause due to anthropogenic or natural reasons. This paper describes the effects of ship-source oil pollution on fishing and mariculture and provides guidance on response measures and management strategies which may help to reduce the severity of oil spill impacts. The environmental impact of the Deepwater Horizon oil spill is still evident a decade later. The fishing industry can be heavily affected by an oil spill. Through the use of the clean-up methods just mentioned, oil may look like it is gone but in fact it can persist in the environment for decades.

TIP 11: Effects of oil pollution on fisheries and mariculture. The underground oil spills are more difficult to catch and yet may be more problematic (oil may reach groundwater more easily and travel with it). Much oil spread at 1100-1300m depth, contaminating and affecting deepwater habitats. Still, >2100km of shoreline and many coastal habitats were affected. Introduction. There is some hope though. A small percentage of oil may dissolve in the water. The BP oil spill began when the Deepwater Horizon rig suffered an explosion … The second major effect of the oil spill is seen on the economy. Every form of pollution including oil spill has its effect on people and environment. Describe case studies of the ecological effects of oil spills at sea and on land. Thus, the oxygen withholding capacity and the percentage of oxygen in water decreases. According to Nelson, (1999) pollution is said to occur when there is a release into the environment of substances and energy in quantities which are detrimental to man and other living organisms. Oil spilled into the water, having been pushed by winds and currents, often reaches the shore. That spill is considered the most infamous oil spill in U.S. history -- although the 2010 BP leak in the Gulf of Mexico proved to be even worse, surpassing Exxon Valdez in scale. Initially, fishermen reported an uptick in fish with skin lesions. It's considered to be the largest oil spill in U.S. history. A 2017 study estimated that of at least 402,000 sea turtles exposed to oil during the spill, 51 percent were Kemp’s ridleys, the smallest and most critically endangered species. The most apparent effect of oil spills is the impact they have on the water itself. Such perceptions are understandable as they are often fuelled by distressing images of oiled birds and other wildlife. Oil spills can also affect human health. Aquatic beings cannot thrive in toxic environment and that makes oil pollution a disservice to them. Effects on marine life : oil spills have negative impact on the marine animals. Part of the oil waste may sink with suspended particulate matter, and the remainder eventually congeals into sticky tar balls. Oil that contains volatile organic compounds partially evaporates, losing between 20 and 40 percent of its mass and becoming denser and more viscous (i.e., more resistant to flow). Other factors include what kind of exposure and how much exposure there was. Thick layers of oil may coat rocks, beaches, or plants. Oil spill has direct and indirect effects on human beings and environment among which are the following:Problem for Ecosystem: Oil spill creates problem for the ecosystem most especially aquatic beings. This affects the marine animals as there is less oxygen in water. Because oil floats on top of water, less light penetrates into the water, limiting the photosynthesis of marine plants and phytoplankton. Petroleum contaminants, if consumed, pose a significant threat to human health, so when an oi… Tests on edible seafood caught in that area do not show excess hydrocarbons in the food supply in the region. This means more barrels have to be imported from other countries. Oil spill, leakage of petroleum onto the surface of a large body of water. The paradoxical effect of the spill is that scientists know more about the Gulf of Mexico, as well as the physics, ecology, and chemistry of oil spills, than they ever would have otherwise. However, other species and areas are not showing the same kind of promise. Since oil products include a lot of common fuels, it is obvious that oil spills may happen at high rates and in many locations, including residential areas. The fishing industry in the area has seen their catches return to normal levels.
