    Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension.[1] They are most frequently made of polyethylene but can be of other petrochemical plastics such as polypropylene and polystyrene. They are used in exfoliating personal care products, toothpastes, and in biomedical and health-science research.[2]

    If these aren't microplastics, what are?

    "Micro" just means "small" in this case and doesn't mean "microscopic" or have anything to do with "micrometer".

    The definition of "microplastic" according to NOAA: "Microplastics are small plastic pieces less than five millimeters long".

    The problem with that, is that if you include everything "small" in the definition, the word loses all it's meaning, feeble as it is already.
    The word microplastic was introduced to describe not just any small piece of trash, but specifically that very small, invisible, pieces of plastics that are, as it turned out, everywhere, in the air, in the water, in our food, in our blood, even in space. If you add just small pieces of rubbish to it, we remove all the sense from the word, and will need another one.
