Follow up to previous postings on the Gulf Coast oil spill, this EPA news release: [the agency] released two peer reviewed reports concerning dioxins emitted during the controlled burns of oil during the Deepwater Horizon BP spill. Dioxins describe a group of hundreds of potentially cancer-causing chemicals that can be formed during combustion or burning. The reports found that while small amounts of dioxins were created by the burns, the levels that workers and residents would have been exposed to were below EPAs levels of concern. Controlled burning of oil on the surface of the ocean (also called in situ burning) was one method used by the Unified Command during the Deepwater Horizon BP oil spill, to reduce the spread of oil and environmental impacts at the shoreline. A total of 411 controlled burn events occurred of which 410 could be quantified, resulting in the combustion of an estimated 222,000 to 313,000 barrels of oil (or 9.3 to 13.1 million gallons).
