During . in-situ. Burning of Oil from the Deepwater Horizon Spill. Goal. Estimate the atmospheric deposition and ground-level air concentrations of dioxin resulting from the ocean-surface burning of oil from the Deepwater Horizon spill, to support a screening level assessment of health risks due to inhalation and due to consumption of dioxin contaminated seafood.
