Deepwater Horizon oil spill 17 of whom were treated for injuries. The Deepwater Horizon sank on the morning of 22 April 2010. The oil leak was discovered on the afternoon of 22 April 2010 when a large oil slick began to spread at the former rig site. The oil flowed for 87 days. BP originally estimated a flow rate of . The Flow Rate Technical Group (FRTG) estimated the initial flow rate was . The total estimated volume of leaked oil approximated with plus or minus 10% uncertainty, including oil that was collected, making it the world's largest accidental spill. BP challenged the higher
Health consequences of the Deepwater Horizon oil spill fetuses. For example, 2-butoxyethanol is a human health hazard substance; it is a fetal toxin and it breaks down blood cells, causing blood and kidney disorders". Louisianan's Governor Bobby Jindal said those impacted will be compensated by BP. An RNA sequencing study found that a combination of Corexit and oil may weaken the cell junctions of airway epithelial cells, which is seen in asthma and cystic fibrosis. The authors of this study posit that the results of this RNA transcriptomic study could provide evidence for the mechanisms through which BP oil spill workers experienced respiratory oxidative stress and associated symptoms.
