Seafood samples contain high levels of microplastics in US state, say researchers

Microplastics were detected in almost every seafood sample found off the coast of the western U.S. in a recent study. The particles were found in the edible tissue of six different species of fish....                        ...                        ...                            ...Microplastics were detected in almost every You are not allowed to view links. Register or Login found off the coast of the western U.S. in a recent study, researchers claim. ......The study, led by Portland State University (PSU), identified "anthropogenic particles" — which are materials produced or modified by humans — in the edible tissue of six different species of fish. ......Those included black rockfish, lingcod, Chinook salmon, Pacific herring, Pacific lamprey, and pink shrimp, according to a PSU press release.......You are not allowed to view links. Register or Login......Specifically, the peer-reviewed study found microplastics — "tiny particles that shed from clothing, packaging and other plastic products" — in 180 out of 182 samples of seafood that were either purchased at a store or obtained from a fishing boat in Oregon, the release stated.......The highest concentration of particles occurred in pink shrimp, and Chinook salmon contained the lowest......."We found that the smaller organisms that we sampled seem to be ingesting more anthropogenic, non-nutritious particles," said microplastics researcher and study co-author Elise Granek in the release. ......You are not allowed to view links.

Other studies have found high concentrations of plastics in the area in which zooplankton accumulate, and these anthropogenic particles may resemble zooplankton and thus be taken up for animals that feed on zooplankton."......Susanne Brander, an ecotoxicologist and associate professor in Oregon State University's College of Agricultural Sciences, added, "It's very concerning that microfibers appear to move from the gut into other tissues such as muscle. This has wide implications for other organisms, potentially including humans."......The findings were published in the journal Frontiers in Toxicology.......The study authors do not recommend that people specifically avoid seafood, as microplastics have been widely found in other food products, Granek noted in the release......."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," she said. ......"What we put out into the environment ends up back on our plates."......The high You are not allowed to view links.

"Toxicity depends on dose and exposure duration — and currently, we lack a definitive understanding of linkage between the oral intake of microplastics and nanoplastics and the adverse effects in human health."......You are not allowed to view links.

"In fact, the levels reported in this study are within the global average."......"Given that humans already consume microplastics from multiple sources — including water, air and packaged foods — the presence of microplastics in seafood should be considered within this broader context rather than as an isolated risk," she added.......You are not allowed to view links.
