So is IQ a "largely pseudoscientific swindle" to quote a popular article from a few years ago, or is it not? Because if the consensus is that it doesn't matter, then why bother using it as a metric here?
I'd like to point out that, although it is illegal to put lead in water supply lines in the US, there is a loophole that allows it in hot water lines. As a result, for certain fittings, most big-box hardware stores only sell the leaded variants, and label them "hot water heater supply line" or something similar.
Why are there so many loopholes in every single US law? Everytime there’s a major health issue or anything extremely anti consumer it’s because of a loophole in the formulation of a US law. Are US lawmakers that bad? Or is it judges who interpret laws literally instead of using the intent?
And lead is still allowed in aviation fuel. The planes (only piston?) are spraying it all over you every day.
Is this actually true? I think that’s changed. Also - how much of a problem is it? What kind of lead exposure do I receive from a small airplane flying over me one day? What does this risk compare to, say, smoking? Or not wearing my seat belt? Simply stating that a bad thing exists is not enough.
Now that there's an approved unleaded replacement for 100 Octane avgas (G100UL), I expect leaded fuel will disappear quickly. Airports are currently in the process of installing the new tanks to dispense it.
Many of the bay area airports already started offering unleaded 94 Octane (UL94) at the pump as of earlier this year.
(Pilots don't like leaded fuel any more than anyone else. It's way too easy to get on your skin during a preflight check. We really want it gone.)

edit to add: I suspect a small plane flying over you one day is no problem at all, but there are many general aviation airfields very close to places where people live and work.

I don't have a vested interest in the lead industry, but it's pretty clearly not simple maleficence.

The IQ tests measure something and we can correlate that thing with other aspects like academic performance, other test scores, income, wealth, etc.
It’s a useful comparative metric, but it is not useful when people try to use it for things like racist bullshit.

None if you use quality lead-free solder.
Unfortunately lead-free solder is a lot harder to solder with; it just doesn't flow as nicely. Companies doing it in an automated way have long figured it out though. This is why hobbyists are often still using leaded solder, particularly outside of the EU. But also in the EU, because it just flows so damned nice.
I find SAC305 to wick into joints faster than leaded solder does, provided you have quality flux in the solder.
If you get the cheapest lead-free solder you can find on Amazon it will be bad.
Doubly so if you have a non-temperature-controlled soldering iron. Too cold, and it won't melt effectively. Too hot, and exposed metal will oxidize rapidly.

Its not gone... pretty much every single person that shoots guns need to be aware of this. Of course gun people don't care about their health and they think with their 45 ug/dL lead level that youre "overreacting"... D-Lead is a very good company for deleading that i use obsessively, when shooting I once called them and talked to an engineer about lead for like 1.5 hours. I think it really surprised him someone was s…
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…

There's a lot of argument that lead-free solder isn't as good (or easy to use) and several hobbyists still use leaded solder.
Have you ever tried the lead free stuff as compared to a good 60/40 or something like that? It's horrid to use. And the lead-free stuff is far worse in manufactured equipment - how many devices have failed early due to BGA solder joint failures that basically didn't exist before RoHS requirements? I think the nVidia 8600M issues were traced to that, and plenty of other BGA equipment since 2006 or so has failed rather…
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.
