PCBs and other contaminants building up in food chain; migrating turtles face higher risk
By Summit Voice
SUMMIT COUNTY — A study of 29 radio-collared sea turtles suggests that turtles migrating north along the coast are being exposed to higher levels of man-made endocrine disrupting chemicals — called persistent organic pollutants because they don’t break down in the environment.
The migrating turtles face cumulative poisoning as contaminants infiltrate the food chain through prey species, such as crabs, according to the researchers.
The landmark study used satellite tracking to link geography with pollutants and revealed potential risks posed to this species threatened by manmade chemicals. The research, published today in Environmental Toxicology and Chemistry, examines the different levels of chemicals in the blood of both migratory and residential turtles. (more…)
