Researchers find chemical cocktail in Australia turtles

AFP, SYDNEY

Human medicines and household substances have been discovered in the blood of green turtles in Australia’s Great Barrier Reef, researchers said yesterday, highlighting the impact of artificial matter on marine life.

Medications for the heart (milrinone) and gout (allopurinol), as well as cosmetic and industrial chemicals, were among hundreds of thousands of substances detected in the reptiles’ bloodstreams as part of an ongoing conservation project.

Scientists said exposure to the substances had caused side effects in the turtles, with indications of inflammation and liver dysfunction.

“Humans are putting a lot of chemicals into the environment, and we don’t always know what they are and what effect they are having,” said Amy Heffernan of the University of Queensland. “What you put down your sink, spray on your farms, or release from industries ends up in the marine environment and in turtles in the Great Barrier Reef.”

Researchers tested turtles at Cleveland Bay and Upstart Bay along the Queensland coast, as well as more remote Howick Island, as part of the “Rivers to Reef to Turtles” project led by WWF-Australia.

The 2,300km barrier reef, a UNESCO World Heritage Site, is already under pressure from farming runoff, development, crown-of-thorns starfish and climate change, suffering its most severe bleaching on record last year.

WWF-Australia said the turtles could be used as a biomonitoring tool to find out what chemicals were entering reef waters and what their impact on marine life could be.

In 2015, scientists said that a chemical used in sunscreen could be causing massive damage to coral reefs worldwide and threatening their very existence.

The chemical, oxybenzone, was causing “gross deformities” in baby coral, the study said.
