Sea samples contain high levels of microplastics in the western US -U: study
Microplasty has been discovered in almost all Seafood pattern They were found from the Western US coast, a recent study, according to researchers.
The study, led by the Portland State University (dog), identified “anthropogenic particles” – which are materials that produce or modified people – in edible tissue of six different types of fish.
They include Black Rockfish, Lingcod, Chinook Salmon, Pacific Herring, Pacific Lamprey and Pink Shrimp, according to a press release.
Microplasty found in a prevailing majority of American meat, water, plants: study
In particular, the review of the study discovered microplastics-“small particles spilled from clothing, packaging and other plastic products”-in 180 out of 182 seafood samples or purchased in a store or obtained from a fishing ship in Oregon, the edition listed.
The largest concentration of particles appeared in pink shrimp, and Chinook salmon contained the lowest.
“We have found that smaller organisms that have sampled are swallowed by more anthropogenic, non-non-chasing particles,” said microplastic researcher and study of co-author Elise Granek in edition.
In a new survey in water bottles, they contain tens of thousands of ‘tiny plastic particles’
“Skampi and little fish, like herring, eat fewer food products Like zooplacton. Other studies have been discovered by high concentrations of plastic in an area where zoplankton accumulates, and these anthropogenic particles can resemble zooplacton and thus download for animals that feed zooplacton. “
“What we brought into the environment ends with our plates.”
Susanne Brander, ecotoxicologist and associate professor at the Faculty of Agricultural Sciences Oregon State State University, she added: “It is very about the fact that microfigers from the gut are moving to other tissues like muscle. These have broad consequences on other organisms, including and people. “
The findings were published in Frontiers in Toxicology.
Is it safe to eat the seafood?
Studies authors do not recommend that people especially avoid the seafood, because microplastics are widely found in other food products, Granek noted in an edition.
“If we disposal and use products that release microplastics and microplastics enter the environment and take over the things we eat,” she said.
“What we brought into the environment ends with our plates.”
High Microplasty prevalence In seafood samples does not automatically mean that seafood consumption is a direct health risk, according to Bing Wang, a doctor of science, an associate professor of risk assessment for food safety at the University of Nebraski-Lilln.
“” Safe “is a relative term in toxicology,” Wang told Fox News Digital. “Toxicity depends on the dose and duration of exposure – and we are currently lacking in the final understanding of the connection between oral intake of microplastics and nanoplastics and harmful effects on human health.”
The study associates the risk of mental health with this toxin for those born in the 60s or 70s
Experts agree that the nutritional benefits of seafood, such as high quality proteins and omega-3 fatty acids, play a key role of UA Healthy dietAccording to Wang.
“There is no current evidence to suggest that the consumption of seafood is an immediate danger to human health,” she added.
Pollution sources
Wang told this study that it was crucial to recognize that nanoplasty outside microplastics was also present in the environment and food supply.
“Unlike microplastics, which can pass through digestive system With minimal absorption, nanoplasty is small enough to exceed biological barriers, including the intestinal mucosa, which potentially reach the bloodstream and accumulate in the organs, “she warned.

In the findings of the dog, 80% of microplastics detected among samples were derived from clothing or textile fibers, but there are other sources of contamination.
Since the 1960s, plastic production has increased by about 8.7% per year, according to Andrew Ortiz, a doctorate at the Department of Science and Technology of Food at Nebraska-Lilln University.
“A large part of the contamination comes from everyday human activities, such as irregular disposal of plastic products, waste systems and inadequate waste management systems, which lead to plastic intake and at the end of the ocean reach,” Ortiz told Fox News Digital.
Completely avoiding microplastics is challenging, Wang emphasized.

“They are widespread in the environment and are present in various food sources, not just seafood,” she said.
“Although this study is the first of its kind in the Oregon region, its findings are aligned with global research About microplastic contamination in seafood, “Wang said.” In fact, the levels reported in this study are within the global average. “
“There is no current evidence to suggest that seafood consumption is a direct danger to human health.”
“Given that people already consume microplastics from multiple sources – including water, air and packaged food – the presence of microplastics in seafood should be taken into account in this broader context, not as an isolated risk,” she added.
