... IN MICE !
They do these kinds of studies on mice because mice have a high homology with humans, and a huge number of the findings extrapolate to humans.

Purchased drinks taste different in different containers (Coke in plastic vs glass vs aluminum), so I’m on board with food.
Coke in "aluminum" is actually coke in plastic; the cans are lined.
I think they're talking about McDonalds which uses stainless steel tanks for delivery. I'm pretty sure those aren't lined with plastic.

Both of those things are straight-up improvements, even if they're not perfect. You can nit-pick every single thing all you want, but better is better.
Changing the container your soda comes in is like sanding off splinters from the sharpened stake you're about to stab into your leg.

What products use PFAS whose absence would cause society to collapse? If you look at the major sources of PFAS by 3M, it's not like these were essential products. Here's a random list from wisconsin.gov: Cleaning products. Water-resistant fabrics, such as rain jackets, umbrellas and tents. Grease-resistant paper. Nonstick cookware. Personal care products, like shampoo, dental floss, nail polish, and eye makeup. Stain…
I think the biggest material impact for any curb on plastics would largely be felt in medicine. Disposability is huge in preventing infection. Also, many medical implants rely on the combination of elasticity and strength found in plastics.
Medical use of plactic is a minuscule minority of plastic use. The vast majority of disposable, single-use plastic is not actually necessary. I'd be shocked if less than 90% of single-use disposable plastic was from food containers. Hell, I'd be pretty surprised if it were less than 99%.

#175My mum when I was a kid in the 90s: we don't store things in plastic, glass or ceramic only Me when I was a kid in the 90s: mum is a f'ing idiot wtf is wrong with plastic this hippy shit is dumb My mum 2020s: so plastic huh? Me 2020s: ugh.
What are the concerns about the “plastic” carpets in American homes? They are pretty much everywhere. They shed fibers all the time. We’re in contact with it all the time.
Yeah, polyester/nylon/polypropylene are everywhere. There are some really good, reasonably priced all wool ones available here: https://hookandloom.com/browse/undyed-natural-wool-rugs/loom...
They’re so much nicer than the plastic type, and seem durable so far (the thick flat weave type has been holding up well on our stairs).

One of my favorite quotes is: "A problem is a challenge with a least one workable solution. A dilemma is challenge with multiple choices, all equally bad." If we eliminated all PFAS chemicals today, society would collapse. What's the point of eliminating PFAS chemicals to improve life expectancy if the very act of doing so would cause a famine?

There are probably no products for individual consumers that contain large amounts of PFAS and that are indispensable.
Small amounts of hard to replace PFAS may be contained in devices such as antenna connectors for devices with WiFi (which cannot cause pollution unless destroyed in an inappropriate way).
Nevertheless PFAS are absolutely irreplaceable in various chemical equipment used in chemical analyses and in various fabrication processes, for instance in the fabrication of all semiconductor devices (because no other substances have comparable corrosion resistance). PFAS would also be very difficult to replace in a few other applications, e.g. vacuum seals and insulators for high-frequency applications (as no other materials have a similar combination of low dielectric constant and low losses).
In all such industrial applications the risks of pollution are much smaller than in mass-market applications. However, it is likely that after PFAS will hopefully no longer be used for mass-market applications their price for professional applications might increase a lot, causing some price increases in other products, e.g. electronic devices.

#177I personally try to avoid canned drinks and foods to avoid metal poisoning. I typically buy two liter sodas in plastic bottles and avoid softer plastics. Styrofoam cups and other styrofoam food containers are awful. If you get hot food in a styrofoam go box, the box is often visibly marked by contact with hot food and you can smell it and taste it. It's also potentially a reason to switch to an electric vehicle -- to…

Exactly!
I dont think I have had a 'soda' in at least 15 years.
I havent been able to avoid plastic in my life - but I try.
For example, pretty much every spoon in my drawer is Bamboo.
I have a 'hippy' friend, and he has nearly zero plastic in his kitchen - and he exclusively eats with wooden utensils, stoneware or wooden bowls.
I think that ALL single-use-plastics should be replaced by corn-plant-based materials.
Single use plastic should be taken out as aggressively as the nazis! :-)
Its so bad for everything.
We should also be burning down DOW Chemical and the major plastic manufacturers for their lack of any accountability, responsibility.
Look at the documentary "the devil we know" about Teflon.

#178Yes those N95 and other disposable masks people have been wearing for years are made of plastic. This is a great way to ingest nanoplastics.
So are HEPA filters in all air purifiers.
Pick your battles. First you don't want to be sick/die/cause your elder relative to die by infecting them. Then once you are not dead you don't want to get into your body substances that clearly have no business being there and can make you sick slower and less noticeably.
I'm guessing you would want to run a filter/wear a mask if there's a good reason and not do it when there isn't.

#179How can nanoplastics be removed from the intestine?
I think the article insinuates that it gets excreted or decays by itself over time.

It's a lot more complicated than that.
And I will note that I drink a lot of tea and fruit juice, which also come in plastic bottles. Most drinks come in plastic or metal containers these days. Most of the time, I buy mine in plastic containers.
I wish it were different and I've lived without a car for more than a decade in the US. Try advocating for a less car dependent infrastructure in the US. It gets you mostly pissed on.
Individuals have limits on how much they can control given the larger context of the world they live in. Attacking my consumption of cola drinks as the focus willfully ignores my real point that styrofoam food containers are dramatically worse than plastic bottles.
