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
Deepwater Horizon oil spill figure, saying that the government overestimated the volume. Internal emails released in 2013 showed that one BP employee had estimates that matched those of the FRTG, and shared the data with supervisors, but BP continued with their lower number. The company argued that government figures do not reflect over of oil that was collected or burned before it could enter the Gulf waters. According to the satellite images, the spill directly affected of ocean, which is comparable to the size of Oklahoma. By early June 2010, oil had washed up on of Louisiana's coast and along the Mississippi, Florida, and
