A plastic microfiber found in the exhaled breath of a bottlenose dolphin is nearly 14 times smaller than a strand of hair and can be seen only with a microscope. (Miranda Dziobak/College of Charleston,tissue damage, excess mucus, pneumonia, bronchitis, scarring and possibly cancer, bottlenose dolphins help scientists understand the impacts of pollutants on marine ecosystems – and the related health risks for people living near coasts.
Since plastic melts when heated, we used a soldering needle to test whether these suspected pieces were plastic. To confirm they were indeed plastic,Our study highlights how extensive plastic pollution is – and how other living things, including dolphins, are exposed. While the impacts of plastic inhalation on dolphins' lungs are not yet known, people can help address the microplastic pollution problem by reducing plastic use and working to prevent more plastic from polluting the oceans.
