More than 4000 toxic chemical compounds, including heart and gout medication, pesticides and industrial adhesives and metals, have been found in the blood of Great Barrier Reef turtles.

Findings from a joint Griffith University and World Wide Fund for Nature-Australia study released today reveal the staggering level of chemicals being absorbed by coastal green turtles.

Scientists also detected signs of poor health associated with exposure to chemical pollution in the turtles.
