So, the very best way to avoid the further accumulation of [toxic_substances] in your body is ... simply ... to go ahead and die." I get it.

However, I do observe that many hundreds of generations of "actual people" somehow managed to be born, live, maybe prosper, and then die upon this planet, in spite of everything that we now proclaim to "know."

As I referred-to today in another thread: "measurement bias." The [mere ...] fact that you are now able to measure something, causes it to now be assigned too much importance.

In places and times where they did not understand that it was the lead, people often had tremors and mental fog by late middle age because of the poisoning and nerve damage. Generally they died far earlier than those who lived away form lead contamination. They managed to reproduce and life quite a while, but only a fool would want to return to THAT!

Yawn. Another one of those sky is falling threads. As above if you don't chew on it, you'll be fine. Shoot we crimped lead sinkers with our teeth back when. We reload lead bullets all the time. And of course solder pipes and electronics with lead. All you have to have is some 'common' sense ... which seems lacking in a portion of our population. Wash your hands when done and keep hands away from nose and mouth and ventilation in the case of soldering. Simple.

I do hope you are giving your audience reason to doubt your intelligence and ability to make valid points?

More seriously, small amounts DO you harm, but the smaller amount the less harm. The valid point is that what you get form electronics directly is trivial (less than that split shot sinker even). IF it goes into a landfill with tons of other lead sources you will get the harvest in your water supply, and a few years of drinking unfiltered water is likely to do you a LOT more harm.

No reason to go crazy about this, but GOOD reason to filter your water and be aware of lead (and arsenic) sources and how to keep that out of your body.

All I tried to point out that lead isn't the bug-a-boo that it is made out to be. Lead is a natural occurring element and is already in the wild so to speak. One doesn't have to believe 'if I touch it... I die', but that is how some portray lead. Like in the PCB board referenced above. It is not 'very very' toxic as said in post #1. Now Mercury? Or some snake bites? Another matter....

Its true... alzheimer for instance is one.

Exhaust system of vehicles, cars: "metal", toxic.

Dont drink water from tap.

Been using Mexican solar still for years

But usually. The water drains into a plastic container. Cuz plastic is everywhere.
I am pushing 80 years so kinda hard to care.
No Alzheimer here. I don't suffer from being insane. I embrace it.

Still ride motorcycles though. Still can walk. USMC body and concentration camp gene pool.
YMMV though.
Wonder if I'll be riding when 100. Think of me like Will Shatner He is looking good for his age also.

I pretty much grew up like rclark says.

When I was a kid, my chemist dad brought home some mercury for us to play with. It was definitely fun stuff. It acts like it's "wet," but it isn't.

I taught Secondary (High School) Science and Mathematics. Many of my science classes got to "play" with things, but I taught them all the precautions and why we had them FIRST. (Hey, after the first explosion they were a lot less bored. And I had fun!)

Yes, many things are toxic.

Don't eat the tablet.

One can wash their hands.

Lead is a 30 year problem. That is why you notice issues with children when they get exposed. Things like paint and even spices contribute the heavy metal intake. So I assume if you are 90 years old you can consume a bit of lead.

@wpeckham: You remind me of my "high-school chemistry teacher!"

I seriously believe that "lead paint" got a bad rap. It is very important in making paint which lasts a very long time. Yes, "lead is sweet," and so some kids pulled peelings off the wall and probably ate them. But I never felt that it presented the actual health risk that was presented. Instead, it seemed to produce "new paints" which wore off much more quickly. Good for business, I suppose . . .

https://www.latimes.com/archives/la-...219-story.html among others.
THOUSANDS of children suffered neurological damage due to lead levels in paint, water, and other vectors. The lead paint aged and rained a slow, invisible, silent poison onto everyone dwelling in the house where that paint was used. Reduced IQ is one of the first permanent effects. There is no safe level.

Paywalled or ID walled but excellent article https://www.theatlantic.com/health/a...-paint/275169/ the portion you can read for free is enough to give the idea.

And make no mistake, it is not in the past. IT is problem today, and will be well into the future.

In Mexico, A-Hepatitis can be ... in tap water?

I've lived on rain water collection for almost 40 years but I do buy drinking water.

Might study this still idea. OHH, its just reverse osmosis?

Solar stills filter that.
