Microplastics: No longer a "maybe" (ibbi.io)

We’ve seen it with lead, asbestos, and PFAS — decades of denial, then belated regulation, then generations living with the consequences. The only difference is timing —and whether you wait for policy to catch up or act on what the science already shows. Think it’s time to push for more studies on the health consequences of microplastics

I have often wondered why the government doesn't do anything about this. Is the science not clear enough yet?

Quick search shows that we knew about lead hazards as early as the 1920s/1930s, but it took until the 1970s to get regulation about lead paint and gas - hoping we don't repeat that in this case

Many of these microplastic studies [1-9] rely on small sample sizes (e.g., n=10 for brain tissue) and detection methods that could pick up contamination from lab equipment itself. It reminds me of when everyone was afraid of BPA

And what defines a “microplastic”? There’s so many different types of plastics that all have different effects on the body

What’s really the health trade-off compared to having to monitor every tiny little thing

>In diseased tissue samples of people with chronic illnesses (IBD [6], Dementia [7], heart disease [8]), microplastic prevalence is significantly higher than healthy tissue.

this is very much not the same thing as "microplastics cause chronic illness", even though it's worded in a way that clearly wants to make you think that.

Aren't nanoplastics a larger concern?

All microplastics out in the open will degrade to nanoplastics at some point, and those find it much easier to infiltrate the human body. They penetrate the blood-brain barrier.

This leads me to believe that it's literally impossible to avoid. The air/water supply must be getting more poluted by the minute with these things

Any thoughts on the temperature of plastics? Looks like a takeout container at 95C (soup, for example) can release 50% more particles than at 50C [1], but how much of overall ingestion comes from this source? Several friends of mine avoid takeout for this reason, is that rational?

I have mixed feelings about this. On the one hand, I think microplastics, and the chemicals that leach from them, plasticizers, are incredibly serious issues. In fact, my company, NeutraOat (neutraoat.com), is creating a modified oat fiber supplement to trap plasticizers in the gut and remove them from the bloodstream.

On the other hand, as other commenters mention, a lot of the studies on microplastics are sloppily done and the conclusions are overreaching. These toxicology studies are certainly not up to the standard of the safety studies that are run on pharmaceuticals. The question is if they need to be in order for us to take action on microplastics. Personally, I think the risk/reward ratio is now clearly in favor of taking action on microplastics, even if I have some problems with the studies and I'm not as confident as the OP.

Saying, "I avoid plastic products" is kind of like saying "I never smoke" while sitting in a room filled with people smoking.

There is no avoiding it. We are all surrounded by plastics in the air, water, soil, etc.

there are no arguments that propose the health benifits of micro plastics......
