That hope that is true. All of this plastic might just be inert and not cause any damage. Who knows how long have people been having microplastics in their bloodstream. Decades? It is just that no one tested for it.
The “better detection” excuse is always there. The major source of microplastics is probably clothes dryers according to one recent study. That means you can associate its risk to probably clothes dryers, microfiber cloths, and plastics in clothing. Adoption of those is going to have accelerated dramatically in the last 30 years or so.
