Micro plastic contamination has been spread in seafood sampled in recent research, and has been added to the increase in dangerous substances in national food systems and the increase in threats to human health.
In the research of peer reviews, microplastics were 99 %, that is, 180 out of 182 detected microplastics, and seafood samples were purchased from Oregon fishing boats at the store. The highest level was found in shrimp.
Researchers also determined that the most common type microplastics are fibers from clothing or textiles that represent 80 % or more of the detected substances.
The results of the survey emphasize serious problems with the current scale of plastic, said Ellis Graneck, a micro plastic researcher and research co -author of the Portland State University.
“I use plastic as a major element in my daily life, and as long as I use it over a wide range, it will be found in food,” said Graneck.
Micro plastic is detected by water samples around the world, and food is considered to be the main exposure route. In recent studies, all meats are discovered and tested products are produced.
Micro plastic contamination may contain 16,000 plastic chemicals in any number, and is often related to very toxic compounds such as PFA, bisphenol, and phthalate. It is associated with neurotomy, hormone destruction, or generating toxicity.
Materials can cross the barriers of the brain and the placenta, and those who have it in the heart tissue may have a heart attack or stroke in the next few years.
In this study, we found that five kinds of fish and pink shrimp were sampled, and that microplastics could move from gully and mouth to the meat eaten by humans. According to Granek, researchers suspect that high -level shrimp and herring are likely to be eating plankton on the surface of the water.
Plankton often accumulates on the front of the sea and moves at the same tide like a microplastic. The young snail, which feeds around the riverbed, also shows a high level, but the level has dropped due to the old snacks moving to the sea.
Chinook salmon showed the lowest level, but there was no comparison between apples and apples. Researchers mainly looked at the fillet, which is eaten by humans, and checked the whole body of small fish and shrimp.
Large animals eat small animals, and substances accumulate processes called biological enlargements, so the pollutant level level is higher than the food chain. Perhaps it was not observed here because fish are supplied in areas where microplastics are concentrated.
Perhaps the Micro Plastic level was probably higher than the one purchased from the boat, so Lingcod purchased from the store was higher. In the processed shrimp and the shrimp purchased from the boat, the level was slightly high, but not statistically significant.
The author is not recommended to avoid seafood because microplastics are widely found in meat and agricultural products. Therefore, changing the meal pattern is not useful. They found that rinsing seafood could reduce the level.
At the individual level, the washing machine is the main source of contamination, so people can reduce clothing, wash with cold water, and avoid synthetic fabric and fast fashion.
Ultimately, the solution needs to come at the policy level, need to reduce plastic use, and need a filter to catch a micro plastic in the washing machine.
A bill that demanded that the critic was rejected by the government Governor Gabin Newsum, who passed the California Congress in 2023 but had caused the pressure of the industry. A similar bill was introduced in Oregon.
“If you don’t want a microplastic for food, you need to make a change to your daily practice,” GRANEK says.
