Microplastics threaten the Barents Sea marine ecosystem

Microplastic concentrations in the Barents Sea, a highly productive area adjoining the Arctic Ocean, were measured by scientists from the Plymouth Marine Laboratory and the University of Exeter. The study found microplastics were more abundant nearer to land and closer to the ice edge, especially near sources of anthropogenic pollution and ice melt. This suggests that zooplankton in the region are likely consuming microplastics, which could have negative effects on their fertility, growth, and the transport of carbon and nutrients to deeper waters. Local sources, such as tourism, shipping, and fishing, may also contribute to higher microplastic levels near the coastline. (Science Daily)
