Durham, NC – Workers exposed to oil dispersants during cleanup of the 2010 Deepwater Horizon oil rig disaster are likely to experience respiratory issues and other health problems, according to a new study from the National Institutes of Health.

The risk of small or medium oil spills from ships, pipelines, storage facilities and refineries is higher than from oil exploration and production. However, the risk of severe oil spills is highest from exploration and production, according to a recent study. Furthermore, the study suggests that the Deepwater Horizon accident, the largest recorded oil spill, cannot be considered as a particularly rare event.

The recent oil spill in the Gulf of Mexico has highlighted the need to effectively evaluate possible response strategies. A new decision support tool can be used to consider the environmental, socio-economic and management effects of different responses to spills, translating them into monetary terms to provide a common currency for comparison.

New research compared criteria for accepting environmental risk as tools to evaluate cost-effective measures that would prevent tanker oil spills. The results suggest that the Cost of Averting one Tonne of Spilled oil (CATS) criterion is the best candidate, as it appears to be both practical and meaningful in actual risk assessments, and can lead to sensible recommendations.

The Deepwater Horizon Oil Spill saw the first ever use of chemical dispersants to reduce the impacts of an oil spill at a deepwater level. A new study has investigated the fate of these dispersants in deepwater and concluded that they do not biodegrade well.

Oil spills can affect seabird populations for at least a decade after a major incident, a new study suggests. The authors studied the long-term effects of the Prestige oil spill on European shags and found that the numbers of chicks raised by breeding pairs were reduced in the ten years following the disaster.

Oil spills can decimate seabird populations. Some birds can be saved, if the oil is washed from their feathers in time; however, this long process is stressful for the birds and requires numerous volunteers. Researchers have now developed a ‘bird-washing machine’ which reduces the washing time from two hours to four minutes. When trialled on oiled birds rescued from the Caspian Sea this resulted in a substantial increase in survival: 88.5% survival after seven days compared to 50% survival with current washing techniques.

Oil spills at sea can be catastrophic events, with oil and discharged toxins, including polycyclic aromatic hydrocarbons, threatening marine wildlife and coastlines, damaging healthy ecosystems and harming livelihoods. A recent study found that using dispersants moderately decreased the number of cod eggs and larvae affected by spills off the Norwegian coast.

European Atlantic countries are, in general, at higher risk of being affected by oil spills than Mediterranean and Baltic countries, with the United Kingdom most affected, according to new research. The study developed a new risk index for analysing the potential vulnerability of coastal regions to oil spills at sea.

Bacteria taken from underground petroleum reserves could be used to effectively break down crude oil from spills at sea, new research has found. The study measured the breakdown of crude oil components in simulated seawater by four bacterial strains that had been isolated from petroleum reservoirs, as well as by four genetically modified stains. The findings raise the possibility of tailor-making organisms to clean up specific types of contamination.

How to Cleanup Oil Spills and Leaks

The dense, bristly hairs on the skins shed by tarantulas when they moult are naturally efficient sponges and could be used to soak up ocean oil spills

The United States has filed a civil complaint against BP Exploration (Alaska) Inc. (BPXA) alleging that the company violated federal clean air and water laws.

Anadarko Petroleum Co., and two related oil production companies have agreed to pay a civil penalty of more than $1 million and implement injunctive relief, develop facility response plans, and revise spill prevention as well as containment plans at a cost of more than $8 million during the term of the settlement in order to resolve violations of the Clean Water Act.

The United States, the California Department of Fish and Game and the California Regional Water Quality Control Board, Central Coast Region, filed a civil complaint today in federal court against Greka Oil & Gas Inc. alleging that the company violated federal and state water laws.
