Have not read the full article but I suspect the dosing and size are unrealistically high. Smaller particles resulted in fewer obstructions ...and that suggests the whole "nanoplastics" scare is another stupidity which is a moot point anyway because monomers and short-chain polymers are very reactive and unlikely to even persist for long.

This winter was very cold here in my city, but that doesn't mean the planet isn't heating up...

People in a few decades will think we were crazy for packaging 100% of our food in plastic, the same way we think putting asbestos everywhere was crazy back then. The amount of strokes and aneurysms that are gonna happen in 20~50 years is gonna be truly fantastic.

Devils advocate here: food has been packaged in plastics for decades and plastic containers have been around longer than that. If plastics were as damaging as you claim, wouldn’t we have already seen this in the epidemiology?

maybe it's more the accumulation. less the plastic wrap rubbing off on the fruit, but the plastic wrapper getting thrown away and ending up breaking apart in the water.

This appears to be a poorly done study-- they're showing the mechanical effect of possible blockage, but they haven't shown that microplastics here are any different than particles of other inert substances found in our environment: clays, silt, organic debris, etc. Those have always been in our drinking water and the immune system deals with what gets into us.

Studying a single subject does not make it “poorly done”. That’s not how science works. A well done research experiment isn’t going to test everything known to man. They’re focused on microplastics and they’ve shown what microplastics can do in the human body. And even if other substances cause the same issue, it doesn’t negate that microplastics cause the issue.

If others have a hypothesis that “microsilt” (is that even a thing?) causes thrombosis in brain tissues, than another experiment can test that hypothesis.

The fact that they have always been around suggest that there is no change to us as a result of their introduction. Plastics, however, have not always been around...

Mechanically, how could this make any difference whatsoever?

Is there a viable way to actually avoid microplastics?

I've been trying to avoid them and it's though. I use glass water bottles, ideally would prefer something like reverse osmosis but not so practical. Remove as much plastic as possible in your daily life: clothes, food containers, bed sheets, etc. Don't eat food that came to contact with plastics and certainly don't eat up food in plastic containers. Vacuum regularly, use a HEPA filtering system to reduce harmful part…

The RO filtration membrane is also made of plastic. I haven’t found a way to avoid microplastics even though I have my own well and have an RO system.

The question is are microplastics doing anything different in this case.

The study shows that microplastics may block. It doesn't show that micro-natural-substances may not also block.

I'd like to see more actual science, and less fear mongering.

Earlier quoted context omitted.

You can reduce the exposure but I doubt you can eliminate it. Live far away from roads, live outside of cities, avoid all plastic containers for water/food, avoid synthetic clothes/bed sheets/towels/&c.

"Live far away from roads" I guess it's microplastics for me

It's pretty much impossible to completely avoid microplastics. They're literally raining down on us at this stage. But it's parts per millions to consider. I remember seeing a video about how all gortex and basically all waterproof great releases microplastics into the environment and then the rain basically carries it everywhere. If I find it ill post it.

All synthetic clothing material sheds stuff constantly from abrasion and in much larger quantities when washing and drying.
