    delicious seafood always makes people want to stop
    .
    Moreover, seafood is rich in polyunsaturated fatty acids and high-quality protein, which is highly respected by nutritionists
    .
    Therefore, more and more people will choose to eat seafood
    .
     
    However, recently there was an article on the Internet saying "Seafood is killing hundreds of millions of Chinese people.
    " The article said that seafood contains a large number of plastic particles.
    The average mussel contains about 900 plastic particles, while six oysters contain about 500 particles.
    In a single serving of prawns, there are an astonishing 9,000 particles.
    .
    .
    Eating seafood is eating plastic, which can cause childbirth disorders and even cause cancer
    .
     
    What are plastic particles? Can I eat seafood with confidence?

    What are plastic particles?
    "Plastic particles" is still a new term.
    As the name suggests, plastic fragments with a diameter of less than 5 mm are microplastics
    .

     
    Due to the very small size, the pollution caused by microplastics may be more concealed and difficult to detect.
    In recent years, scientists have begun to pay attention and value
    .
     
    Where do plastic particles come from?
    Plastic is an irreplaceable material in modern society and is ubiquitous in production and life
    .
    Many plastic materials are not easily degraded, and if they are not recycled, they will become environmental waste
    .
    As the rain washes away, they enter the river and eventually into the ocean
    .
    Plastic floats in the water, is hit by reefs, washed by waves, and bitten by animals.
    It will eventually turn into small debris and further into tiny plastic fibers or particles
    .
     
    In addition, tiny plastic fibers may also come from industrially produced plastic raw materials, such as plastic particles and plastic powders used in the cosmetics field
    .
    Plastic particles are ubiquitous in food
    People have long been concerned about the harm of plastic garbage in the ocean to marine life.
    In recent years, the research on microplastic fibers has attracted new attention
    .
     
    In the past two years, many studies have begun to focus on plastic particles
    .
     
    For example, some studies have found that sea salt and tap water contain trace amounts of plastic fibers, including microplastic fibers and nanoplastic fibers (the diameter of microplastic fibers is 0.
    1-5000 microns, and the diameter of nanoplastic fibers is 1-100 nanometers)
    .
     
     
     
    Seafood is harming people's health? You are making a fuss again
     
     
    Plastic particles are ubiquitous in our environment and enter our food chain through water and soil
    .
     
    Researchers have also found traces of microplastic fibers in sea salt from the United Kingdom, France, the United States, Spain, and China
    .
    In testing tap water samples from 14 countries, 72% of EU samples including the United Kingdom, Germany, and France found microplastic fibers, an average of about 4 per liter of water
    .
    The survey in the United States is not optimistic either.
    Data shows that 94% of water samples contain microplastic fibers, with an average of about 10 per liter of water
    .
     
    Plastic particles can be diffuse in our food chain through water, soil and so on
    .
    Previous similar studies have found microplastic particles in honey, sugar, beer and fish
    .

     
    Therefore, it can be considered that there may be trace amounts of plastic in all foods
    .

    What is the risk of plastic particles?
    In fact, due to the stable chemical properties of plastic, the harm it brings to the human body should be minimal, and it will be excreted from the feces when eaten
    .
     
    The main health risks of plastic particles that people are worried about may come from the various pollutants it accumulates/adsorbs, such as PCB (polychlorinated biphenyls) and PAH (polycyclic aromatic hydrocarbons) adsorbed in the ocean
    .
    In addition, there are additives used in the production of plastics, such as BPA (bisphenol A)
    .
    A few scholars believe that it may enter the human organs and blood system, but this is only a concern at present, and there is no scientific evidence
    .
     
    Persistent organic pollutants adsorbed by plastics are a problem, such as dioxins, polychlorinated biphenyls, etc.
    , but considering the very low content of microplastics in food, the harm it brings is far less than that of other pollution sources
    .

     
    Although various foods may contain microplastic fibers, seafood is the most typical
    .
    The plastics in marine fish are mainly concentrated in the digestive tract, which is basically removed when people eat them, while filter-feeding bivalves (such as oysters and sea rainbow) are eaten with the digestive organs
    .

     
    Scientists in the European Union have estimated that there are about 7 mg of microplastic fibers in 225 grams of Haihong
    .
    Calculated according to the currently known maximum pollution amount, the resulting intake of PCB, PAH and BPA is minimal.
    For example, the intake of PCB and PAH is less than 0.
    1% of the total daily intake of the human body, and the intake of BPA is insufficient The human body accounts for 2% of the total daily intake, so the threat is small
    .
     
    The World Health Organization has begun to organize an assessment of the health effects of microplastics, but has not yet reached an assessment conclusion
    .

    How to treat microplastics?
    In fact, there is very little research on plastic particles
    .
    Whether microplastic fibers are harmful to human health is still inconclusive
    .

     
    From the current point of view, it is necessary to control the use of plastics, reduce the use of plastics, and strengthen plastic recycling from the perspective of environmental protection.
    However, for the general public, there is still no need to worry too much about the plastic particles in the food, and eat regularly to ensure food diversity.
