So you’re correct in saying you’d need more information to draw conclusions, but the big concern at this point in time is that we really have no idea what impact this has. This is potentially much worse than eating a bunch of plastic one time that you’ll ultimately pass right on through (given that these are microscopic particulates in the digestive tract).
In essence the big concern here is cancer. We know that particulates at or around 0.3 microns (the Most Penetrating Particle Size) have been linked to a variety of abdominal cancers in humans throughout the last hundred years.
Critically, these types of cancers can take up to 50 years to form and cause serious enough problems to be detected (and seldom less than a couple of decades), so although billions of people have consumed micro-plastics, we still have no way of knowing what impact that will have on their health in later years.
This is exactly what happened in the case of asbestos - it took so long for the consequences to show up after exposure that it seemed far-fetched to draw a correlation between asbestos and the cancers it caused. When coupled with cover-ups of the evidence by mining companies, the common use of asbestos skyrocketed long after it was known how deadly it was in private - but before public awareness had sounded alarm bells.
The worry is that accumulated micro-plastics could be deadly in later life, but that we don’t find that out until hundreds of millions of people have become terminally ill.
