title: Comparison of pollution levels on the Mississippi Gulf Coast during the 2010 Gulf BP oil spill to ecological and health-based standards.
abstract: To evaluate the possible impact that the BP Deepwater Horizon Gulf oil spill might have had on pollution levels in the State of Mississippi, the Mississippi Department of Environmental Quality (MDEQ), and the US Environmental Protection Agency (EPA) analyzed surface water and ambient air quality pollutant data taken from MDEQ and EPA monitoring sites on the Mississippi Gulf Coast. The data were compared with acute, chronic, and human health air and water quality standards to determine whether the pollutant levels occurring during the oil spill could cause ecological and/or human health effects. The water quality data indicated levels of nickel, vanadium, volatile organic compounds (VOCs), and semivolatile organic compounds analyzed remained below acute and chronic levels for both aquatic life and human health. The air quality sampling data showed that the levels of VOCs and polycyclic aromatic hydrocarbons associated with the oil spill were well below EPA chronic and human health screening levels. A comparison of the air quality monitoring data taken before and after the oil spill showed that the concentrations of ozone and fine particulate matter were elevated for brief periods but remained below actionable levels.
