Also, it makes people irritable and more hostile. so if you noticed your city becoming more rude and less polite, it may be that a lot of the people are getting borderline psychotic or personality disorder because of unenforced lead regulation violations.

There were a lot of irritable and hostile people during the Flint water crisis. Many of them stormed the capitol: https://abcnews.go.com/US/video/protesters-storm-michigan-st...

I guess that's, ah, circumstantial evidence? But yeah it's a tragedy to see these EPA violations occurring in more rural parts of the USA. What is going on with that?

It’s definitely a concern of mine, thanks for the heads up about that company. For those that aren’t aware, the primer in cartridges typically have lead styphnate, barium nitrate, and tetrazene, among other things. So even if your bullets have a complete copper jacket, you still get significant lead particulate exposure, especially indoors or with a suppressor with high back pressure. No idea if whatever smokeless po…

Are lead pellet air rifles even worse then? I remember cleaning the barrel of one and the cleaning tool was so very dirty.

Definitely wouldn't be worse as there will only be lead dust from erosion of the pellet in the barrel instead of additionally having lead/lead-compound vapor from the heat and chemical reactions.

But it's still a concern, so hands, arms, and face should definitely be washed after loading/shooting/cleaning. Extended firing sessions should be followed by a shower and clothes change.

Fortunately, the elemental lead in cast pellets/bullets is not very bioavailable, however it's still a good idea to minimize exposure.

There is also an exception for leaded gas in small/private jets ("AVGas") so its used in some of those formulations.

That can't be the only exception. Maybe nobody sells it premixed anymore but back in the 90s we had to mix lead additive into gasoline for vintage motorcycles.

Modern octane boosters for classic cars and bikes use other types of cylinder head lubricants.

Do you mean faulty, logic, or faulty, supporting evidence? I think if something is plausible, but unsupported by evidence, the logic can be sound, but the supporting evidence faulty; but if something is implausible, then it would be the logic that was faulty and to me it seems like that crime and behavioral changes are caused by lead is certainly plausible, so I don’t think it’s a logical failure here. It may just be…

See above. The Vox article made this seem like logic around the hypothesis is more faulty than it probably is, given other replies. I understand my meaning might've confused HN commenters but I genuinely feel that the intent of my words in the initial comment is intuitive, and don't have time or bandwidth to argue about the semantics. I am sorry for the confusion. I obviously can't definitively prove it is faulty, an…

Vox, always shillin' for illogic. Hahah

I thought that's what you were doing, intuitively, and I wasn't attacking you. I know how it can feel that way. It's more like a jumping off point for other commenters to hop onto, a group conversation if you will, but the threaded nature does make it look like a direct challenge/reply to you.

You know you can't be sorry for other people's confusion tho, right? That might be some semantics for you! :) haha

Have a good day and thanks for sharing this interesting ref!

I recently fell in love with copper pipes. So many advantages, so easy to work with. Quick and nearly fool-proof. I tried introducing some stainless fixtures and did not have a good time with it. I'm not a pro by any means but I do all of my own plumbing and gas work in my house. Haven't had one issue out of iron gas pipe or copper water lines. I was actually planning a pex install/replacement, and I have worked with…

I had a house where a brand new copper line corroded and started leaking 2 years from installation, and I don't mean at joints or anything, I mean the local water just ate right through the wall of the pipe. I switched to Pex and was fairly happy with it. I never did do the research to figure out what was up with the water, but similarly, when I tried inventing my own sump-pump sensor by dipping copper wire into the…

Convenient point for PEX: If copper pipes aren't properly grounded they'll tend to develop pinhole leaks within that timeframe.

Whats my risk of exposure to lead from improperly made glass or stainless steel?

Stainless steel could easily contain quite some ppm of lead. Metals are frequently recycled, and hard to separate. Glass could also contain lead in contaminants - but actual metallic lead won't end up in the finished product - but lead oxides might well. Having said that... There are probably many devices in your house or supply chain which deliberately contain lead in double digit percentages. Worry about those befo…

> Having said that... There are probably many devices in your house or supply chain which deliberately contain lead in double digit percentages. Worry about those before worrying about contamination.

I cycled pulverized lead paint around my alveoli as a kid doing construction and used to bite lead fishing weights when I was very young to make sure they stayed on the line.

Thankfully it is now stored in my skeletal system for future use by my nervous system.

People often go to Pex because it's way cheaper than copper. I use copper because the rest of my house supply is copper, soldering pipe is a skill that I have and enjoy using, there's a slight anti-microbial action from copper, and I trust it to last longer than I have years left around. I sure don't do it because it's cheaper, though.

I know some plumbers recommend Pex because it fails catastrophically -- if you run a nail through a pipe you'll know it -- whereas copper can have pinhole leaks which will slowly grow mold all over the inside of your wall without you noticing.

I have a conspiracy theory that people recommending leaded solder (And reacting hostilely to suggestions it may be dangerous) are demonstrating the effects of lead exposure. I don't buy the "just wash your hands" argument.

Leaded solder isn't a problem to work with, it's a problem when it contaminates landfills.

Also the supply chain: smelting and refining. Herculaneum Missouri has acres bulldozed of what used to be homes once they learned the children were born with lead poisoning. Before the dozing citizens put up warning signs telling people to take off their shoes when they got home and not to let their kids play in the contaminated public spaces.

Whenever I leave NYC and go anywhere else in the US, walking a mile feels like an act of silent rebellion.

Had a friend from Texas move near me in Australia and they have just been exhausted trying to keep up because they aren't used to walking. Walking here is the fastest and most convenient way to get around. By the time you get your car out and find parking, you could have already been there on foot. You'll observe that the rate of obesity is extremely low in the walkable areas which I really think is heavily because t…

The rate of obesity is low because of survivorship bias, nothing more, nothing less. For obese and/or disabled people, living in New York is an absolute nightmare if you can’t afford public transit.

Despite loving the city amenities, culture, nightlife, one of my family members had to give up and leave NYC because he couldn’t afford cabs everywhere and hated showing up to events late and sweat-soaked otherwise.

It’s money. The answer is money. Somebody makes money by producing lead-infused products, so they pay off lawmakers to add a loophole that allows them to continue making money.

Yet people still maintain the popular fiction that corruption isn't that common in the large western countries, and that it's somehow more prevalent in the east. It's nonsense. Everywhere there are large governments, there is huge corruption that is literally killing people so that others may be enriched without working as much.

Well there are so many social issues that suck the oxygen out
