Pollutants could pose health risks for five sea turtle species – Science Daily

Published on: 06/28/2012

Researchers at the (National Centers for Coastal Ocean Science’s) Hollings Marine Laboratory and four partner organizations have measured for the first time concentrations of 13 perfluoroalkyl compounds (PFCs) in five different endangered species of sea turtles. While PFC toxicology studies have not yet been conducted on turtles, the levels of the compounds seen in all five species approach the amounts known to cause adverse health effects in other animals.

PFCs are human-made compounds that have many uses including stain-resistant coatings, fire-fighting foams and emulsifiers in plastics manufacturing. They have become widespread pollutants, are detectable in human and wildlife samples worldwide, infiltrate food chains, and have been shown in laboratory animals — rats, mice and fish — to be toxic to the liver, the thyroid, neurobehavioral function and the immune system.
