Microplastics found in gut of every sea turtle in new study

Plastic was found in the gut of every single turtle examined in a new study spanning the Atlantic, Pacific and the Mediterranean.

(CNN)Plastic was found in the gut of every single sea turtle examined in a new study, casting fresh light on the scale of plastic pollution in the world's oceans.

The research, published in the journal Global Change Biology, examined more than 100 sea turtles of all seven species, across the Atlantic, Pacific and Mediterranean.
Researchers from the University of Exeter and Plymouth Marine Laboratory, along with Greenpeace Research Laboratories, looked for synthetic particles including microplastics in the bodies of 102 sea turtles.
    More than 800 synthetic particles were found in the turtles and researchers warned that the true number of particles was probably 20 times higher, as only a part of each animal's gut was tested.

      "The ubiquity of the presence of the particles and fibers underlines the gravity of the situation in the oceans and our need to proceed with firm and decisive action on the misuse of plastics," senior study author Brendan Godley, professor of conservation science at the University of Exeter, told CNN in an email.
      The researchers carried out their research by conducting necropsies -- animal autopsies -- on turtles that had died either by stranding or by being accidentally caught by fishermen. The study sites were in North Carolina, Northern Cyprus and Queensland, Australia.
      Synthetic particles were found in all the animals, and the most common sources of these materials were tires, cigarettes, clothing and marine equipment, including ropes and fishing nets.
      "This study provides more evidence that we all need to help reduce the amount of plastic waste released to our seas and maintain clean, healthy and productive oceans for future generations," added Pennie Lindeque, senior scientist at the Plymouth Marine Laboratory, in an email.
      David Santillo, from the Greenpeace Research Laboratories at the University of Exeter, said: "The threats to turtles from entanglement in fishing gear and choking on larger pieces of plastic are well known, but the fact that every turtle investigated in this study, across three different oceans, contained microplastics in their guts reveals yet another, previously hidden, dimension to the problem of plastics pollution."
