Follow up to previous postings on the Gulf Coast oil spill, this new research: “Although the flow of oil from the Deepwater Horizon spill was halted in mid-July, researchers continue to find elevated concentrations of polycyclic aromatic hydrocarbons, or PAHs, in some areas of the Gulf of Mexico. Some of these chemicals are known carcinogens that pose a range of risks to human health. Oregon State University researchers began testing for the contaminant May 9, and preliminary results, which have not yet been fully analyzed, suggest that the level of PAHs in the water off the coast of Louisiana experienced a 40-fold increase from May to June. The July data was lost when the device the OSU team uses for water sampling disappeared.”
