We Are Such Stuff As Bottles Are Made Of
We’ve written before about PFAS, often found in non-stick coatings and the like:
PFAS Exposure & Cancer: The Numbers Are High
Today we’re going to be talking about microplastics & nanoplastics!
What are microplastics and nanoplastics?
Firstly, they’renot just the now-banned plastic microbeads that have seen some use is toiletries (although those are classified as microplastics too).
Many are much smaller than that, and if they get smaller than a thousandth of a millimeter, then they get the additional classification of “nanoplastic”.
In other words: not something that can be filtered even if you were to use a single-micron filter. The microplastics would still get through, for example:
Scientists find about a quarter million invisible nanoplastic particles in a liter of bottled water
And unfortunately, that’s bad:
❝What’s disturbing is that small particles can appear in different organs and may cross membranes that they aren’t meant to cross, such as the blood-brain barrier❞
Note: they’re crossing the same blood-brain barrier that many of our nutrients and neurochemicals are too big to cross.
These microplastics are also being found in arterial plaque
What makes arterial plaque bad for the health is precisely its plasticity (the arterial walls themselves are elastic), so you most certainly do not want actual plastic being used as part of the cement that shouldn’t even be lining your arteries in the first place:
Microplastics found in artery plaque linked with higher risk of heart attack, stroke and death
❝In this study, patients with carotid artery plaque in which MNPs were detected had a higher risk of a composite of myocardial infarction, stroke, or death from any cause at 34 months of follow-up than those in whom MNPs were not detected❞
~ Dr. Raffaele Marfella et al.
(MNP = Micro/Nanoplastics)

We don’t know how bad this is yet
There are various ways this might not be as bad as it looks (the results may not be repeated, the samples could have been compromised, etc), but also, perhaps cynically but nevertheless honestly, it could also be worse than we know yet—only more experiments being done will tell us which.
In the meantime, here’s a rundown of what we do and don’t know:
Study links microplastics with human health problems—but there’s still a lot we don’t know
Take care!
