The effects of oil spill on the ecology

Economic evaluation of oil spill damage. Larger marine mammals and ducks, meanwhile, suffered ill effects because their prey was contaminated. The framework, which represents a synthesis of key findings from a broad literature, provides a mechanism for systematically and comprehensively accounting for the range of factors that influence oil spill impacts.

Although each ecosystem is unique, previous oil spills suggest several key variables Appendix 1, Table A1. Oil spill The first level of consequences relates to the oil spill itself gray boxes in Fig. Vaporized toxins pose a threat to human health Binet et al. Economic sectors that are important in Vancouver, but which were not prominent in other oil spill disasters, may also be vulnerable to oil spills.

It can facilitate understanding of how a spill of a particular volume could lead to very different consequences, depending upon contextual variables and their interactions. Following Valdez, high rates of alcohol and drug use were associated with recovery jobs, especially in Indigenous communities, and there were higher rates of domestic violence and crime more broadly Rodin et al.

Disturbances of this nature typically create space for new organisms to settle and grow.

However, this is a part of nature and rarely causes any major damage. In the year alone, six oil spills were seen in the USA. Notable exceptions include species with canopies that reach the surface of the water, such as some kelp and seagrass species.

Some types of impacts that have been relatively inconsequential in previous events may be very significant in a Vancouver case. The role of insurance in providing adequate compensation and in reducing pollution incidents: To clean or not to clean: The breadth of this review and framework can assist communities at risk, particularly those without prior experience with oil spills, to develop an overview of the spectrum of potential impacts and the key biophysical and socioeconomic factors that influence how these impacts are realized.

Under most circumstances, spilled oil will float along the surface of the water, thereby minimizing exposure of most subtidal species to oil. A basic question remains: First, the proximity to a densely populated urban area with over 2 million residents has many ramifications.

Also, under the international conventions, environmental damages are rarely compensated beyond cleanup and lost profits in fisheries and other marine sectors; in contrast, the OPA explicitly provides for the recovery of damages to natural resources Schoenbaum Modeling assessment of potential fates and exposure for orimulsion and heavy fuel oil spills.

Toxicologic Pathology 40 2: One must understand that oil spill is not the only threat that marine life is facing. Globally, The effects of oil spill on the ecology trade in oil is forecasted to grow markedly in coming decades IEA One notable example is the potential for an oil spill to increase the invasion success of the recently introduced nonindigenous species, Littorina littorea or common periwinkle Harley et al.

Valdez spill leaves bitter residue: There are also numerous First Nations, i. Deep-sea bacteria enriched by oil and dispersant from the Deepwater Horizon spill. Interactions between effects of environmental chemicals and natural stressors: Aquatic Living Resources In water bodies, the spill occurs due to drilling rigs, offshore oil platforms and well.

Ecological impacts of the deepwater horizon oil spill: The local tourism industry suffers a huge setback as most of the tourists stay away from such places. Two years after BP oil spill, tourists back in U. At the core of the framework, summarized diagrammatically in Figure 1, is a linked sequence of outcomes or consequences that lead from the oil spill to its impacts on society: Canadian Coast Guard environmental response: Biological Sciences What Characterises Recovery for the Marine Environment?

Toxicologic Pathology 40 2: In spill disasters in which the oil floats, the greatest exposure will occur in the intertidal zone, where rising and falling tides bring species in direct contact with the bulk of the spilled oil.

The oil works its way into the fur and plumage of the animals. Department of CommerceOxford Economics VANCOUVER CASE Although the framework and the literature reviewed on historic oil spill impacts provide a basis for anticipating impacts of future spills, it is important for communities at risk to recognize the particularities of their situation and how these might be similar to or different from those of previous cases.

Investigations of other technological and natural disasters in coastal cities are needed to augment the knowledge base; for example, examining image-related impacts on tourism and other sectors.Oil Spill: An Ecology Lesson Plan The FDEP has initiatives on Deepwater Horizon Oil Spill Response and Restoration.

The website has information on claims, response and restoration of conducted by the state of Florida in response to This lesson explores the effects of oil on the environment, people, and wildlife.

The students. Oil spill response efforts are designed variously to remove oil contamination, enhance its biodegradation and prevent it reaching the more sensitive parts of the ecosystem, but. 1 EFFECTS OF OIL SPILLS ON MARINE AND COASTAL WILDLIFE Holly K. Ober Department of Wildlife Ecology and Conservation University of Florida Off-shore oil spills can have a large impact on many components of natural ecosystems.

INTRODUCTION Transporting oil from production sources to consumption locations entails risks, most notably, the risk of accidental oil spills, which can cause severe damage to.

Effects of Oil Spills: An oil spill happens when liquid petroleum is released into the environment by vehicle, vessel or pipeline. It happens on. Jun 23,  · Even though oil spills are fairly common, scientists at the two-day workshop say there's surprisingly little research on how they affect human health.

Since the s, one researcher notes, there have been more than 30 major oil spills, nearly all of them involving shipwrecked tankers.
