- Microplastics have always fascinated me, because I keep seeing article after article about how much microplastic exists around us, but far less strong evidence about its actual effects. That is not to say there are no effects, of course. Maybe we just have not found them yet.
A friend of mine worked on her bachelor’s thesis about the effects of microplastics on the immune system, specifically T cells. Her result was that the microplastic particles she studied were too large to interact with T cells.
She probably will not publish this result because she thinks it is not interesting enough. Classic file-drawer problem in academic science.
While I encourage her to do it anyways as a negative results is also interesting but she wanted results that are worthing of headlines in magazines.
- So the article seems to pose more questions than it answers. I was expecting some observations from the plastic-free lab they built, and at least some evidence of the comparative impact vs. other labs that use plastic to study blood and other fluids (besides the 100-times-plastic/phthalates concentration in the air).
What exactly are they studying in the lab? The biggest takeaway from all this is that "we [still] don’t have enough information yet".
- Some stand out takeaways:
> We assessed how reliable current measures are for trying to find microplastics in blood. And what we found is that lipids and fats will give you a false positive for polyethylene.
> We worked with an architect, and we built the lab pretty much from scratch. [...] So we ended up going with stainless steel. It was the only way to not have any plastics.
> I don’t think we’ve got really good evidence at all for what effects [microplastics particles on their own] might be having on human bodies. If we’re eating plastics, what size and what type of plastic can actually get into the bloodstream?
- We don’t fully understand even some of the most obvious pathologies. If a disease isn’t glaringly obvious and coupled with profit incentive, God help you. The question of what microplastics do to us is simply beyond the capabilities of both modern medicine and academic research institutions.

- Would have loved to see the effects broken down by plastic, as the term "plastics" is as non-specific as "metals" and "organic"
- I have grown to accept it. It is part of me now
- fwiw kimchi-derived probiotic bacterium (Leuconostoc mesenteroides CBA3656) was shown to bind nanoplastics and help mice excrete more of them. But it’s not yet proven that eating kimchi removes microplastics from humans

- Did she debunk that article that was around microplastics in human testicles?

- one word: microplastics
- Very nice to see someone actually looking at the issue objectively instead of the unholy blend of clickbait, shoddy "science" and either fear mongering or blind denialism we usually see.
Getting to the point where we're actually able to measure something real is good progress.
- " We tested about 30 different construction materials trying to find some that didn’t contain plastics, but also didn’t contain plastic [additives] such as phthalates, but we couldn’t find any. Everything had either plastics or phthalates in them."
- We’re going to find out at an autopsy.

- tldr, not much because we can't measure it to begin with

- >Even when you put a glass panel in the window, you have silicon holding the glass in. We tested all these different brands of silicon to try to find ones that had low levels of phthalates. It was a crazy amount of detail that we went to, but it was really worth it.
Silicone holds the glass panel. Silicon is the glass itself. Yale editors, do your job. She worked "a crazy amount of details", and so can you!

- we have recently transitioned to only using glass bottles in our family.

- I think hate of plastics is an emergent form of elitism.
Upwardly mobile middle/upper class people who've sort of "maxed out" the amount of personal identity they can buy with regular plastic things can unlock a new level of identity by deciding that plastics are bad for them and eliminating plastics from their life, a process which conveniently requires buying a whole new set of things that distinguish them from their peers.
This is the only way I can explain how irrational and inconsistent plastic-haters behavior is. There is so much invisible plastic in their life that they don't seem to care about.
