Of note, tarballs can also be produced from places … The fishing industry in the area has seen their catches return to normal levels. 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. Valuable fishing areas maybe closed down for any period of time if an oil spill occurs. The oils spread fast over a short time to cover vast expanses of the water body. 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. Over time, oil waste weathers (deteriorates) and disi… The environmental impact of the Deepwater Horizon oil spill is still evident a decade later. However, other species and areas are not showing the same kind of promise. 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. These effects can depend on what kind of oil was spilled and where (on land, in a river, or in the ocean). 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. Every form of pollution including oil spill has its effect on people and environment. Introduction. Environmental Effects. Birds that feed on polluted areas, such as fish-hunting eagles and ospreys, can also feel the disastrous effects of oil spills. Aquatic beings cannot thrive in toxic environment and that makes oil pollution a disservice to them. 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. Oysters in many areas of the gulf are returning. 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. Still, >2100km of shoreline and many coastal habitats were affected. Oil may strand at the high tide line, leaving black lines or globs of oil on the beach as the tide recedes. Effects of oil spills. Natural cause: Cruid oil takes a long time to produce as it needs the organic matter of the organisms which are dead. The fishing industry can be heavily affected by an oil spill. Then comes the process of cleaning the oil spill, which requires a lot of financing. The BP oil spill began when the Deepwater Horizon rig suffered an explosion … Because oil floats on top of water, less light penetrates into the water, limiting the photosynthesis of marine plants and phytoplankton. As late as 2013, Cat Island, an important bird rooker… Tests on edible seafood caught in that area do not show excess hydrocarbons in the food supply in the region. The second major effect of the oil spill is seen on the economy. 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. 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. These spills cause many devastating effects - mainly to animals, but also to plants and to people. Oil spills have many adverse effects on the environment. Apart from these, the oil spill in water may cause by accidental spills, oil discharges, etc. Since most of the oil floats in water, the sunlight absorbing capacity of the water decreases. The Exxon Valdez Oil Spill which occurred on March 24, 1989 in Prince William Sound, Alaska, is considered the Oil spills are harmful to marine birds and mammals as well as fish and shellfish. There are multiple ways in which oil spills can be cleaned in a safe and cost efficient way. Oil spills in water may cause due to anthropogenic or natural reasons. Discuss the potential consequences of petroleum resource development in the Arctic. Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird's feathers, thus … Describe case studies of the ecological effects of oil spills at sea and on land. 1. 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. Dolphin numbers are down. Oil spills have major environmental and economic effects.
