In another article about microplastics, I was surprised at the upper end of the size-range of what is considered ‘microplastics’ (2mm, if I remember correctly). The article focused on the alarming amount of microplastics in the oceans - I’m thinking in order to dramatize the amount, they may have seen fit to be more inclusive by expanding the size-range.
I would be curious to know the size-range of the plastic particles found in these placentas - since knowing that would help narrow down the likely source, i.e., confirm that it was from household dust arising from synthetic clothing and bedsheets, rug fibers, etc..- and suggest what filters might mitigate the problem.
They are found in every placenta (possibly bloodstream) but the biggest difference with normal weight and preterm were PET, PVC, polyurethane, and polycarbonate.
