Somehow, it feels worse if it is an aerosol.

I read the article. Apparently it only really works with hard water - that's water with a high concentration of calcium carbonate. At high temperatures, the calcium carbonate becomes a solid, trapping the microplastics inside it, which is then removed from the water with a regular filter.

So, the boiling doesn’t remove it at all; it pre-treats hard water, making it capable of being filtered out afterwards.

uh... it seems like it.. if that is the case, the whole article is misleading at best.

[–] [email protected] 9 points 1 year ago* (last edited 1 year ago) (1 children)

Would that just mean boiling water and then filtering it?

If so, doesn't seem as misleading so much as just missing an extra step for a headline. Edit: of course, in addition to the hard water specification.

gotta make the water hard too, doesn't work without hard water

[–] [email protected] 3 points 1 year ago (1 children)

But I can't even make myself hard 😭

Many regions won't need that of course :)

Traps it how - guessing as a gas? What the fuck are microplastics and how does clear water trap that? I’m lost as fuck

[–] [email protected] 12 points 1 year ago (1 children)

"calcium carbonate in the (hard) water became solid at higher temperatures, trapping the plastic particles within"

No gas involved. They did recommend straining the boiled water through a coffee filter and the harder the water the better.

If I have soft water, can I add a Tums to my boiling water?

[–] [email protected] 6 points 1 year ago

Just put it in the freezer for an hour or two

[–] [email protected] 6 points 1 year ago

By causing it to be absorbed into the calcium carbonate that is in hard water

[–] [email protected] 3 points 1 year ago

The calcium carbonate in hard water precipitates out when you boil it, i.e. it turns solid.

Microplastics make for great nucleation points for the calcium carbonate to latch onto. So, the microplastics became super easy to filter out of the water (with some getting stuck to the bottom of the kettle in that white scale that you have to use vinegar to clean out.

Nanoplastic kitchen cloud

[–] [email protected] 20 points 1 year ago (2 children)

Luckily I have well water...probably some of the cleanest water on Earth...I've tested it several times with kits.

[–] [email protected] 17 points 1 year ago (1 children)

You tested it for microplastics? They're everywhere. Even on top of mountains

[–] [email protected] 10 points 1 year ago

The Marianna Trench contains microplastics. (not a meme)

The eggs of all newly born children contain microplastics. (not a meme)

But this person's water-well. Free and clear. I think the key is this their well is outside of the environment. (meme)

[–] [email protected] 17 points 1 year ago (2 children)

These fucking clickbait titles.

It only really works with hard water, otherwise you'd have to add calcium to the water before boiling it, and they only tested it with something like 3 different plastics, and they're the most benign and least reactive ones.

This is not a magical solution to clean any water you boil.

[–] [email protected] 4 points 1 year ago (1 children)

Could instead reverse osmosis remove those particles and be used as consumer products?

[–] [email protected] 3 points 1 year ago

Yes to the first, as for the second, who knows, but most likely not, as it'll be mixed plastics and you can't just mix them all together and make something out of them

[–] [email protected] 4 points 1 year ago

I was about to say. The headline sounds like the equivalent of removing mud from water by boiling it.

Removing fine particles by aggregating them isn't a brand new concept either, for what it's worth.

[–] [email protected] 12 points 1 year ago (2 children)

Microplastics are tiny pieces of plastic debris measuring less than 0.2 inches (5 millimeters) long,

That can't be right. There sure ain't 5mm pieces of plastic in my drinking water. 0.05mm would be hard to believe.

[–] [email protected] 2 points 1 year ago (1 children)

Not sure that's correct, but 5 mm being the upper cap doesn't mean they're that long.

[–] [email protected] 2 points 1 year ago

I guess the author has just googled "define microplastics"... but when we think about microplastics in our drinking water we're not thinking about 5mm pieces of plastic.

A consumer grade filter will remove things larger than 0.0005mm.

[–] [email protected] 1 points 1 year ago

Sadly, that is the definition of microplastics. I’m not sure why a 5mm piece is considered „micro“

[–] [email protected] 7 points 1 year ago* (last edited 1 year ago) (4 children)

Disturbing that micro plastics evaporate!

So if we just boil the ocean...

[–] [email protected] 12 points 1 year ago* (last edited 1 year ago)

It doesn’t. Please read the article.

[–] [email protected] 6 points 1 year ago

The oil industry is doing all they can!

[–] [email protected] 3 points 1 year ago

Well, not boiling, but we do heat it up

[–] [email protected] 1 points 1 year ago (1 children)

It bonds with calcium but then they don't say why it's not an issue anymore. Does it become a super stable particle? I don't fully get it.

[–] [email protected] 2 points 1 year ago

They say filter out the calcium

[–] [email protected] 3 points 1 year ago (1 children)

There's going to be some people that are going to start boiling all of their water after reading this article

[–] [email protected] 1 points 1 year ago

Omg yes. Please dont, people.
