Bottlenose dolphins in the Florida Coastal Everglades have higher concentrations of mercury than any other populations in the world.
FIU scientists examined dolphins from the lower Florida Keys, Everglades National Park and Florida Bay, looking for mercury and organic pollutants in their skin and blubber. Not only did they find high mercury levels in the coastal Everglades dolphins, but they found the highest levels of concentration ever recorded. Potential sources of mercury are both natural and from man-made sources. The finding raises concerns about potential impacts on the health of local populations.
