Kinda biologically impossible. Certainly improbable.
I’d like to know what size these ‘particles’ are.
Micro plastics are by definition, 1 nanometer (nm) and 5 million nm (or 5 millimeters [mm]) in size. The smaller sizes are in everything. You cannot sample water anywhere fresh or ocean with out some in it. Same for fish from the ocean. Every sample taken from a human or mammal regardless of where they live or what organ also had quantifiable microplastics. It’s in the waters all of them even rain, soil, feed, foods and air. If you wear synthetic fabrics like polyester it not only sheds on your skin but some of the particles are small enough to pass the skin barrier and be absorbed directly. This means wearing a polyester shirt can put microplastics directly into the blood stream plus what your inhale wearing it.
[studies found the average brain may contain 4,806 micrograms per gram (or 7 grams), which is about the weight of a plastic spoon]
Yeah it’s like this. Our planet is utterly polluted with plastics , something we should stop post haste. Glass, aluminum, paper and wax packaging.
It’s just science. Plastic is a bad idea for food contact, plates cups bottles wrap all of it no. Like I said every wearing it is exposing you.
