> shooting ranges filter air before exhausting it (as dust is formed from impact). Where do you live? I have never shot a gun indoors. Every range I have been to is open air. Multiple states, including California.
Around here the biggest issue is duck hunting, where the pellets almost certainly wind up directly in a wetland.

There's a good episode of 99% Invisible that discusses Prop 65, including an interview with the original author of Prop 65, David Roe: https://99percentinvisible.org/episode/warning-this-podcast-... Yes, there are a lot of problems with Prop 65, but the podcast also highlights the benefits. Slapping a Prop 65 warning on foodstuffs in particular significantly decreases sales, so it's not something you just do merely t…
That's an interesting behind the scenes point of view. But from a consumer point of view: > you don't notice all the products that don't have the label ...because there are too many with it, so people stopped caring. As a consumer, I would prefer a label that identified the major risks.
Did you know, the world still mines more lead now than it did 50 years ago, at the peak of 'put lead in everything' mania? To me, this says that we still put lead in too many things. Lead is still used for flashing in roofs. It's still used as a mould release when making plastics. It's still used in making dishware. It's still used in bullets. It's still used for all kinds of things which will one day end up in the e…
When I posted here about how lead pipes during the Roman Empire was bad for the people I was met with a torrent of downvotes right here on Hackernews saying it wasn’t that bad. I’m not optimistic about the future.
The ancient romans added lead acetate Pb(CH3COO)2 to their foods and wine. I can't understate just how much 'lead sugar' was being consumed.
By the way, in my later years, I did make a voluntary choice to taste it, and then rinse my mouth out. And yes, it was the closest we have to table sugar Ive ever tasted. Before anyone naysays me, I did this knowing full well the risks.
Also fast forward 1700 years,and we see the same reaction. In the 1950s USA, you could buy lead-rimmed coffee cups. The interaction between the coffee, the lead, and your mouth created the sensation of sweetness, likely also lead acetate.

If you must lie, be less bad at it. From the paper [1] she read and you didn't: > It is now universally accepted that utilization of lead for domestic purposes and water distribution presents a major health hazard. The ancient Roman world was unaware of these risks. How far the gigantic network of lead pipes used in ancient Rome compromised public health in the city is unknown...[Lead isotopes in sediments from the h…
...what? Did you mean to respond to me? I'm the one exposing the lie. There's a weird trend on here of karma chasers playing "gotcha" by posting rebuttals to things that literally nobody is claiming and hoping that we don't notice. It's fucking pathetic man. What would it take for you to reevaluate your life.

Damn right, there's absolutely no justifiable reason for using leaded solder for hobby projects today. Get a good iron, and a nice roll of SAC305 from a reputable vendor and you won't have any issues.
Does modern lead-free soldering still end up having tin whiskers? That was always the big downside as far as I was concerned. A quick internet search implies it's still a thing.
Pure tin (or Sn99.3Cu0.7 alloy) is garbage, the silver helps a bunch.
For demanding applications there's apparently some even more performant alloys available today, eg. Innolot [1].

Fishing tackle.
TIL that this is still legal in some states. (I grew up in New Hampshire, which banned lead fishing weights decades ago, mostly to protect loons from eating them.)

You’re confused. The original post you linked is literally downvoted all the way and has three comments with disagreeing sentiments. Water pipes made of lead are bad for you and were bad for the Roman Empire.

Nobody is confused. If the downvotes caused you to show us who you are, then they performed a duty, just not the expected one or one that you are enjoying.
