A new study reveals that microplastics, originating from human waste and pollution, have been detected in the edible tissues of nearly all fish and shellfish examined off the Oregon coast. Researchers found microplastics in a wide range of species, including rockfish, lingcod, Chinook salmon, Pacific herring, Pacific lamprey, and pink shrimp. The presence of these particles raises concerns about their potential impact on human health, although further research is needed to determine the long-term effects.
In the Pacific Northwest – a region of North America renowned for its seafood – researchers have found particles from our waste and pollution swimming in the edible tissue of just about every fish and shellfish they collected.
Brander and her colleagues are not arguing that people should stop eating seafood altogether, but it's important that consumers and scientists understand the level of exposure."If we are disposing of and utilizing products that release microplastics, those microplastics make their way into the environment, and are taken up by things we eat,"The fish, shrimp, and lamprey included in the study.
In the coastal waters of Oregon, filter-feeding shrimp had some of the highest concentrations of plastic waste accumulating in their bodies. Researchers suspect this is because shrimp exist in the upper water column, near the surface, where floating plastic and zooplankton converge.
