>stop buying things that have a prop 65 warning (I know prop 65 isn’t perfect, but it’s often a lead warning). That would seem to mean to stop buying an enormous number of things. Extended to locations, it would mean not parking in any enclosed parking lot, or entering a number of different stores. It's not clear to me it's even possible to avoid everything with a prop 65 warning. Unfortunately, the bad incentives in…

It's extremely rare that I come across products with a prop 65 warning. And in the rare chance you do see it, like on a bowl, you might learn that some bowl paints and glazes actually have lead in them!

Second, information is not meant to be executed on directly... you are supposed to process information with critical thinking. Yes, enclosed parking lots give you cancer. Guess what, you can still park in it... In the same way that tuna contains a lot of mercury but I still eat tuna.... just less of it. I rather know and make an informed decision than not know anything at all.

The US is probably going to put more lead into everything because RFK Jr believes it builds character or something.

His whole thing is about environmental toxins probably being the cause of most of our problems, so no that doesn't seem likely.

This aged wildly poorly.

There can even be lead in fruit pouches: https://www.cdc.gov/lead-prevention/news/outbreak-applesauce... I'm far from crunchy, but this led me to start making my kids pouches. They're more expensive per pouch, which was a bit surprising, but it has the side benefits that we make the pouches together (quality time) and I can control what goes in (e.g., spinach, carrots, broccoli).

I am glad you are finding the time to avoid contaminated industrial processed food. In the apple sauce contaminations the apple sauce is always cinnamon flavored.

I am a metal worker, and a foodie, living on a farm, and have experience and contacts in varios parts of the food industry, and have never come across lead, in any food relate items. As to alloying with lead, it has been used historicaly to make steal easier to machine "free machining steel" , but has no part in high strength or tool steels, and the steels used in grinding machines are going to be food grade..... even the grease in the bearings is food grade silcone grease....got some in the shop.... Good stainless wears for ever, so it is always used, at least here in Canada. So back to the lead and heavy metals, and how they are intentionaly added as "flavor enhansers" and coulorants, and basicaly how crazy people are and will do anything to steal a buck, but of course, not before passing it.right! personaly I eat only food, I make from individual single ingredients, prepared at home. The most complex food I buy is cheese, and very rarely icecream, thats it.And even then, there are things that just seem WRONG, like some grapes, that had an impossible "floral" aftertaste that lingered for hours......and now wont rot, sitting on top of the fridge. I could go on at some length, about all of the fraud in food, but Food is cheap, and there is no way to impliment a system with continious checks and investigations, that would guarantee quality and purity, without quardrupling the price, and perversly, increasing the incentive, to cheat.

Don't scream at me, but what about non-industrial, hobby soldering? AFAIK soldering is not hot enough to vaporize lead.

Soldering contamination mainly comes from ingestion. Touching it, having small particles of lead burn off and land on your skin, then in your mouth (or eyes, elsewhere). Even so, by washing hands and wearing light PPE it’s fine. Because if that, many people consider the ban of industrial lead solder to be over-zealous. But that ban is in place to stop consumers being contaminated if they somehow touch the board. Also…

I love my Kester 40% lead solder and always use gloves when using it. Probably an overkill since I have been soldering since 90s.

Yes, EVs still have a 12V battery, but it’s not always lead acid. Tesla, for example, switched from lead acid to Li-ion 12V batteries in all their models several years ago. So have Porsche, even in combustion models I believe.

They are a lot more expensive though, at least aftermarket.

Yes but you have to replace them much less often. Kind of like LED vs incandescent light bulbs.

> “even if we were to completely stop mining for and using lead (which we aren’t, since the lead-acid battery market is projected to increase in the next years” I’m surprised by this. Modern cars (EVs, at least) have started replacing their 12V lead batteries with Li-ion, which are more durable, store much more energy, and of course are less toxic. But in any case, isn’t the one advantage of lead-acid batteries their…

The lead batteries have always be 90%+ recycled (well, at least since any time we should care about). So the amount of mining is still proportional to the amount of batteries running around.

Right. The recycling rate is around 99%, apparently. So the number of lead batteries running around only has to shrink by 1% per year before we don't need to mine any new lead for batteries. Something that seems likely to happen in the coming years as EVs become dominant and Li-ion gets cheaper.

> test children’s lead levels and your own

Here's a tip for your peace of mind: if you suspect that some food you're consuming is high in lead, get tested first before removing that food from your diet. I was consuming a fair amount of dark chocolate when I first learned that it could contain high levels of lead, so I got tested before I cut it out of my diet. My levels were below the detection limit so I can be reasonably sure that any damage caused by lead consumption was minimal.

Note that:

* since 2018, the warning must include at least one specific chemical (but not all of them)

* unlike initially, manufacturers nowadays often only label products sent to California, so the benefit for residents of other states has largely disappeared

So the lead in food comes from color and flavor additives. How did it get into those ingredients?
