Microplastic-eating plankton may be worsening crisis in oceans, say scientists
The creatures are converting plastics from micron sized to nano sized particles amplifying the lethality in number and effects.

There's plenty of research in progress:Progress will be slow because the investigation is multi-disciplinary.
Toxicological impact of microplastics and nanoplastics on humans: understanding the mechanistic aspect of the interaction

The really big hazard is the particles bring other substances, organic and inorganic, with them as they perfuse through tissue, something that is facilitated 1000-fold by being a nano vs a micro. This seems to be mentioned quite a lot in most summaries.
Here's a recent e.g. out of Perth, doesn't seem hysterical:

Not going to spend all day on it, suffice to say the plastics are emerging as a major disaster...

Tabby is a remarkably ignorant right-winger. He probably believes what he reads in the Murdoch-owned media - and is silly enough to read it.

Tabby is a remarkably ignorant right-winger. He probably believes what he reads in the Murdoch-owned media - and is silly enough to read it.
I don't bother reading it. That you resort to making silly things up says a lot.

They already have a health disaster, it's called the human race.

Nonsense.
"West said the study's most surprising findings are the tight bonds formed between the plastic and the protein within the area of the neuron where these accumulations are congregating, the lysosome.
Researchers said the plastic-protein accumulations happened across three different models performed in the study—in test tubes, cultured neurons, and mouse models of Parkinson's disease."
Definitely a challenge to analyze human brain neurons in vivo.
Absence of proof is not proof of absence, as they say...
