Microplastic pollution in the Chesapeake Bay poses risks, report finds

Plastic debris like this breaks down in the environment into smaller and smaller bits. (Dave Harp)

According to the Chesapeake Bay Journal, tiny bits of “microplastics” that wash into the Bay may endanger aquatic life in the estuary and its tributaries, but more research is needed to better understand the threat, according to a report from scientists and policy makers released Monday. Although federal legislation was approved in December that addresses a portion of the issue, the report from the Chesapeake Bay Scientific and Technical Advisory Committee said the law did not eliminate the need to find new ways to reduce microplastic pollution and recommended additional legislation to address the issue, which is of growing concern for waterways around the globe. Microplastics – pieces of synthetic polymers smaller than 5 millimeters – are found in water bodies everywhere, with more than 5 trillion pieces of plastic floating at or near the ocean surface, according to a recent estimate.
