Microplastics are already entering human food supplies such as fish and seafood, Australian researchers warn | The Weather Channel – Articles from The Weather Channel

Microplastics have been found in varying concentrations in blue mussels in the intertidal zone – areas where the ocean meets the land between high and low tides – of some of Australia’s most popular and remote beaches.

According to researchers at Flinders University in Australia, this implies that microplastics are now making their way into human diets, including wild and sea-farmed fish and seafood from once pristine ocean waters. Southern and Gulf of South Australia.

Microplastics are any type of plastic that is less than 5mm in length. From the summit of Mount Everest to the deepest oceans, it has become the most pressing environmental and health issue.

“Our findings highlight the urgent need to prevent microplastic pollution by working with communities, industries and government to protect these fragile marine systems,” said Professor Karen Burke da Silva, Dean of the College of Science and Education. engineering from Flinders University.

The team sampled varying levels of microplastics at 10 popular beaches in South Australia, including Coffin Bay and Port Lincoln on the west coast, Point Lowly and Whyalla on Spencer Gulf, various popular Adelaide metropolitan beaches and beaches bordering Victor Harbor, Robe and Kangaroo. Island, according to the article published in Total Environmental Science.

Low to medium levels of microplastics measured in the common blue mussel (Mytilus spp.) – a filter feeder affected by ecosystem conditions – were measured to analyze the main types of pollution affecting the environment, and plastics for use single turned out to be the main offender. Microplastics are ubiquitous in the marine environment and tend to be more abundant in mussel samples near major cities, the team found.

“By investigating the microplastic load in the mussel, we draw attention to the implications of microplastic pollution on South Australia’s unique marine ecosystems and the local human food chain,” said first author Janet Klein. of the item.

Trillions of microplastic particles exist in the world’s oceans, with the highest concentrations recently found in shallow seafloor sediments off Naifaru in the Maldives (at 278 particles per kg) and the lowest reported in surface waters of the Antarctic Southern Ocean.

The team found that concentrations of microplastics in South Australia’s intertidal waters were low to moderate compared to global levels, and that the abundance of microplastics in mussels was within the range also reported at the global scale.

Recently, scientists from the University of Hull and Hull York Medical School in the UK discovered microplastics in living human lungs for the first time, indicating that we are inhaling dangerous substances without realizing it. This has the potential to have a significant impact on our respiratory health.

Microplastics have also been found at detectable levels in cosmetics and the human bloodstream.
