Are picoplastics possible? And would those be even worse? And what would single molecule of plastic be called? Would it be somewhere between zepto or yocto that is -21 or -24 exponent... Considering Avogrado's constant is 6e23...

"Plastic contaminates everything, even your implant. The plastic breaks but does not degrade. The microplastic becomes nano plastic, which breaks and becomes picoplastic which breaks and becomes femtoplastic and so on." [1] No use getting fearful until you see some evidence. There's a lot more to fear right now to your immediate existence, if you want to exercise that nerve.

  > The microplastic becomes nano plastic, which breaks and becomes picoplastic which breaks and becomes femtoplastic and so on. This cannot be true. Atoms are nanometer sized, so breaking down particles into pico- and femto-plastics would involve nuclear reactions that I feel reasonably safe asserting do not occur naturally. If they did they would change the chemical structure of the products into something no longer plastic (and in fact no longer matter of the form we're familiar).

>Are picoplastics possible? A single hydrogen atom is about 0.1 nanometers in diameter. You can't really have complex molecules that are smaller than nanometer scale. >And what would single molecule of plastic be called? A monomer is what the smallest unit of a polymer is called. They're a single molecule, but so is a long polymer chain of a bunch of them bonded together, and the properties of the material often depend heavily on the number of monomers in the average chain in the bulk material. For example, the monomer of polyethylene, one of the most common plastics, is a gas at room temperature/pressure. So it may not really make sense to call a monomer a molecule of plastic.
