Studies like these always make me wonder what the equivalent of this today. Microplastics? Carbon? What else?

Lead. It’s not gone. And maybe some PFAS? We don’t have great data, and PFAS isn’t reliably disclosed in products. (Also, surely different perfluorinated chemicals have different effects.)

There are lead detection q-tip swab kits but annoyingly they also test positive for copper. I didn’t realize that until after I threw out a copper tongue scraper.

But I did find that one of my girlfriend’s keychain trinkets tested positive while saying “stainless steel”.

> Many airports stopped selling 100LL in January of 2022. Really? That is news to me. Googling reveals that two airports did that, both in the same county: Reid-Hillview Airport (KRHV) and San Martin Airport (E16).

Bay Area bias, sorry. Many airports near me did. I have no knowledge about Oklahoma.

> Many airports near me did.

Could you list a few of the many? I looked around Bay Area airports, and found most of them selling 100LL:

  KSFO - San Francisco International Airport - $9.90         
  KHAF - Half Moon Bay Airport - $6.42                       
  KOAK - Metro Oakland International Airport - $8.21/$8.64   
  KHWD - Hayward Executive Airport - $7.99/$7.55             
  KPAO - Palo Alto Airport - $6.35/$6.95/$6.59               
  CA35 - San Rafael Airport - $6.84                             
  KSJC - Norman Y Mineta San Jose International Airport - $10.07/$8.95  
  KLVK - Livermore Municipal Airport - $6.54/$7.54                
  KCCR - Buchanan Field Airport - $7.15/$6.98                   
  KDVO - Gnoss Field Airport - $7.67/$7.87                         
  KAPC - Napa County Airport - $9.20                                
   0Q3 - Sonoma Valley Airport - $8.00                              
   C83 - Byron Airport - $6.35                                  
   0Q9 - Sonoma Skypark Airport - $6.30                  
   O69 - Petaluma Municipal Airport - $6.95

Are there? It seems like plastics are shaping up to be the modern day lead.

Plastics for potable water tend to be copper lined where I live, not sure what is used elsewhere.

I've never heard of copper-lined PEX, can you tell me more?

...We don't...? Who?

In the past it was common knowledge not to. It's of much more uncertainty as house plumbing has changed.

That's because it is primarily a historical artifact[0]. Most modern plumbing heats water on-demand, which pretty much entirely avoids the risk of storage tank contamination or Legionella.

Just a data point here, an acquaintance of mine gave himself lead poisoning by visiting the shooting range too often for target practice. I think he wears a breather when he goes now.

Wow -- how often for how long were/are they going?

Some of my bloodwork revealed subclinical lead poisoning. Part of the investigation was to take the dirty A/C filter in for lab analysis of the dust. I had lead in that filter, so I moved out. No idea where it came from. EDIT: It was an apartment. FWIW, even new apartments can have other issues, like a brand new place my friend was working on had rampant mold issues (built & exposed throughout monsoon season). So you…

Who bought the place after disclosing airbourne lead dust in the house?

Soils in many major US cities can have high amounts of lead. If you're not controlling how much dust is tracked in that very well could be detected.

If the water was already hot because I was doing something else, I'll make soup or pasta with a pot of hot water. If the kitchen were closer to my water heater, I'd do it more consistently.

If you ever find yourself cleaning the inside of a hot water heater some day, it will disabuse you of that habit. I'm sure it's mostly harmless, but they accumulate a truly horrific amount of mineral deposits and other weird gunk in there.

Looking inside a kettle in London provides the same experience (at least when I lived there).

Now we live on rain water and the inside of the kettle is pristine, despite bird crap on our roof and flora in the guttering.

That's not correct. It depends on the water filter. A common Brita filter doesn't filter lead. But the referenced filter (Epic) does. There are other filters that can do that, the most popular is ZeroWater, which you can check their datasheet https://www.zerowater.eu/wp-content/uploads/ZeroWater-NSF-ce...

The problem with ZeroWater is it filters out everything. I would be always thirsty after drinking from ZeroWater, it was a weird feeling.

So then you have to remineralize it...

But how are those minerals being sourced, and does that mixture contain lead? Ugh, it never ends.

Goodhart's law strikes again. As soon as IQ becomes a measurable thing, populations that measure it will act in ways that increase it. Shocking, I know.

It's interesting how closely tied "goodness" and "intelligence" are. To make a mistake is to be a bad person. To be stupid is to be bad. I can call you weak. I can even call you ugly, cowardly or a flibbertigibbet. But if I call you stupid look out! Like our whole worth as humans is summed in our ability to talk smart and solve riddles like a trained animal. Which seems pretty stupid.

It will seem even stupider once computers can convincingly do all the "intelligent" things better than us.

In fact, they can already seem smarter, even when they're not.

Maybe we can move on to prioritizing humans on other criteria -- like how nice they are to each other, how good they are at making nice art, or skiing an amazing line down a mountain, etc.

Lead roofing tends to get recycled into bullets in time of war, but those roofs that don't, are typically there forever (400+ years) and never leak. Some plastics are UV resistant due to additives but even copper struggles to compete with lead as a roofing material. You only need to look back to the 1970s to find PEX water piping and the disaster/flooding it can cause due to age.

Are you thinking of polybutylene pipe, rather than Pex (cross-linked polyethylene)?
