Health consequences of the Deepwater Horizon oil spill effects, while even very low doses can cause mutagenic effects, with cancer of particular concern. The carcinogens of concern in crude oil are benzene and polycyclic aromatic hydrocarbons (PAHs), which are present in oil and in the air as a result of offshore controlled burning of crude oil. During the 2010 BP/Deepwater Horizon Gulf oil spill, an estimated one of every 20 barrels of spilled oil was deliberately burned off. Routes of exposure include contact and inhalation. The EPA obtained hundreds of air samples during the spill and a review showed that none of the samples showed concentrations of benzene
Oil spill governance in the United States oil spill in the Gulf of Mexico suggest more can and should have been done in this area. Evidence of this fact is present in the recommendations and investigations present in the January 2011 report by the recently established National Oil Spill Commission. A further sign of lack of proper governance is implicit in the action of the federal government to rename and reform the Minerals Management Service (MMS) into the now Bureau of Ocean Energy Management, Regulation and Enforcement. The 1989 "Exxon Valdez" oil spill served as a major focal point in oil spill governance and reform. Prior to
