I grew up next to the largest lead-silver refinery in the world, in Trail, BC, Canada. I also spent some time working there, mostly in the lead baghouse, which collected lead dust. Yes, literally walking around in piles of lead. It was definitely an experience. We had our blood checked every 2 weeks to make sure that our lead levels weren't getting out of control. Interesting story! They actually used to think that milk decreased lead levels, so the plant actually had it's own dairy farm. Workers got free milk! Less lead in the blood! Until they realized that the milk was drawing the lead into the bones, as it tried to replace the calcium there.

Not to debate about that water, but notice that he said "no safe level of lead *in the blood.*" There's a difference between trace amounts of lead in drinking water and lead buildup in the blood.

Just as an aside the Flint fiasco had to do with the affect the new water source had on the old Flint lead pipes. The old pipes had a crust of water residue which protected the public from the lead.

Why they had used lead in the first place when all this damage was known I don't know.
@@fredworthmn I just recently learned it all started when they switched to a new water source. I didn't know about that build up inside the pipes you mentioned, though.

dangerousmythbuster Colonel Mustard may have suspected something if another piece of lead pipe showed up. A toothpick would have caught him completely unawares.
I'm glad that I didn't have lead poisoning, but a friend of mine that I had a special romantic feeling toward back when we were both 6th Grade students at my former middle school got it. The condition that he had was so bad that plenty of adults had to take this opportunity to observe the palm of his hand. It was unknown if he had to go to the school nurse or not that day. Safety first when you're around lead at all times.
I knew people in El Paso, TX who had lived in Smelterville, a small neighborhood for the workers next to the ASARCO smelter. Their homes were built on the slag pile and everything was thoroughly contaminated with lead and other heavy metals. It was shut down and the people relocated in the early 1960’s. None of them seemed to be suffering any long-term effects from their exposure.
I think statistically humans are bad for everything except humans. Wait, scratch that, humans are bad for everything. Wherever we go "there goes the neighborhood."
When I took college biology classes the action of heavy metals on proteins was discussed. Proteins are complex molecules that twist and fold themselves into complex shapes. Heavy metals degrade those molecules by causing them to unfold and untwist so they are not useful to the body. The proteins that make brain and nervous tissue are especially susceptible to damage caused by these metals. The brain isn’t turned into mush, but the proteins that make the nervous tissue don’t work the way they should.
And to think that lead was once added to gasoline until the late 80's. It has been hypothesized that one of the contributors to lowering the crime rates worldwide has been the ban on leaded gasoline. Given lead's affect on human behavior and the fact that crime rates started to decrease right around the time when lead was being phased out from gasoline, it makes sense.
Once you've siphoned leaded gasoline once, you'll never wonder if it's a bad idea again. The part of your brain that thinks about those things will be broken.
We prefer intelligent criminals because they do swindling, cheating, other crimes than knocking us in the head, prying our doors open, personal crimes.

One of the symptoms of lead poisoning is also a reduced ability to taste salt. Which is part of why the ancient Romans ate so much of the stuff - because they used lead in their pipes, at the very least as a sealant. They apparently ate so much salt in their diet that even the most salt-hungry American would be disgusted by the excess salt in Roman food.
So lead is like my friend Anthony at every job ever: An enthusiastic failure who manages to break things, experiment with chemicals, and not follow proper procedures, all the while managing to somehow stay around for years. Fantastic!
So if I had some unknown lead poisoning as a kid but didn’t know it, and I could easily have in the 80’s, it could account for my anxiety and terrible appetite I always remember having and to this day still do. At 35 it may only now be going away depending how old I was if I was exposed.
I served US Navy 1980 to 2000. We had a primer paint called Red Lead. We could apply it over rust and it worked fine. I used it extensively. We never were issued any PPE. It was all over our skin and uniform. We used Dry Cleaning solvent PD-680 to clean up. I always wonder if I have been affected by all that including all the greases and hydraulic fluids we used.
There are many people who deny that lead is harmful and think it has no negative effects. I always refer to those people as key instances of the effects of lead.
I am sure all this is true, but let’s face it, we have had lead pipes for centuries in this country and yet we became one of the leaders in the world of science , industry and various other disciplines. So it begs the question. If we were all ‘lead zombies’ so to speak, how did we do this? Not to say that we shouldn’t be cleaning up and reducing lead pollution everywhere, but it is a question that needs to be answered.

That's incorrect. Metallic lead is less toxic than many other lead compounds, but still totally toxic to the human organism. Even handling metallic lead will allow some to be absorbed into the skin.
I worked with a class of 6 "autistic" kids. They ranged from 11 to 15 but were considered to be in 2nd grade. The 15 yr old was a normal kid until he was 6ish and ingested lead paint from in his home. He was the farthest behind in the class. :(
People often credit the scientific method with all sorts of things. But it turns out humans are pretty good at deducting things without it, hundreds of years before its existence. Of course based on the same simple concept of reasoning.
we used to bite lead weights onto fishing lines ...and I worked on a building site where some guys would chew lead ! Still that might explain a few things ….
One of the better explanations. Good job! Keeping it succinct isn't easy since the stuff really does muck up everything it touches. biologically speaking. Will you also at some point cover some of the other "bad metals" we've learned about? I seem to recall reading somewhere that at the start of the Industrial Revolution, people were using discarded slag from mines as a kind of weed deterrant for their gardens - the specific mention I'm remembering described a family spreading copper tailings (I assume that means slag, right?) around their hedges to keep down the weeds and grass. Their small child got hold of one such bit of waste and - well the results were of course unfortunate. So it'd be interesting to learn about the history of how we learned what not to put in our gardens and so on. Or even just "why is copper bad for the body" similar to this video.
When I first started driving in the late sixties you might see three gasoline pumps with one labeled ethyl. This was short for tetra ethyl lead. It was an inexpensive way to increase the octane rating. It was about this time it was decided that putting lead into the atmosphere probably was not a good idea and was then banned.
Those aren’t stupid ideas, lead paint is one of the most durable, longest lasting types of paint, and it prevents wood from rotting. It’s extremely opaque so it can be spread thin without needing a second coat, and brushstrokes smooth out flat, allegedly. And lead pipes can be shaped and bent with just your bare hands! It’s abundant so it’s a no brainer why a person living two thousand years ago would use it for just about everything. If lead wasn’t toxic it would be EVERYWHERE, because it’s one of the most useful metals of all
@@Bloated_Tony_Danza It might be useful but it is harmful. That's why OP asks if people were stupid. Can you believe that people used it once as a gas and inhaled it in large quantities through almost 1 century? Sometimes you have to stop to think about usefulness and start to think about effects it has on your body instead.
Can lead from the metal in machinery like old sewing machines get airborne? I have 2 machines made in India. I tested the metal and lead is on every surface! and in the oil. I imagine it gets in the oil from parts moving and friction causing contamination of the oil. But this oil get on my hands, so I wear gloves now. But I really want to know if it can get into the air? How worried should I be. I have to use these machines, they are very specialised and very rare.
What about mercury? And which is more poisonous, mercury or lead? And I remember hearing that other metals can be used to bind to one of these heavy metals and reduce it's toxicity, but I can't remember whether it was lead or mercury and what metal binded it (cadmium?) If you know anything about that, please do tell.
Yeah, the most toxic substances to humans usually do end up being inhibitors of bodily processes or tricks the body into thinking it's another substance. I would've liked to have seen a few minutes why lead is toxic and yet a similar substance like Bismuth isn't toxic. Great video regardless.
deadly lead blood level is under 100ppb and to put that into perspective, pretty much every toxin blood level is measured in ppm because having a few thousand parts per billion is usually not a big deal. not with lead.
I'm not sure about there being no acceptable lead level. I worked at a lead smelter and those that actually worked at or around the smelter had quarterly blood tests to make sure their levels were not climbing too high. Working that close to a lead smelter every day for hours means exposure is unavoidable. After about 9 months there I had my heavy metals checked and i had minimal exposure. Though the contracted janitor, who wasn't supposed to contaminated areas, did get lead poisoning. After a fire in the smelter break area, the workers had to use the general break area and they drug in lead dust on their shoes, which he then in he inhaled. He didn't know it, but they were supposed to clean that breakroom, but they didn't and they never told him not to clean it. He got deathy sick.
When I worked at a automotive dealership, i always wore gloves when I balanced tires. Guys there called me a bitch, I would laugh it off, but be thinking, "well at least I wont have some type of blood cancer when I'm in my 40s or 50s. BTW for those of you who don't know the counter weights that go on your car's rims to make them balanced are 100% lead.
I like that the human race has known how bad lead is since bc days and Flint was just like, "Eh, it's ok to let lead be in the water," for going on 6 years. I was able to move a year ago but I still have many of these symptoms with no clue when or if they will go away. My eye sight and hair loss seem to be permanent.
Isnt lead useful to protect against radiation? If I shield my house with lead walls against radiation, which is more dangerous the lead or the radiation?
Do take my words with a grain of salt. There are many types of radiation that already exist everywhere, Alpha, Beta, and Gamma. The first 2 are too weak in penetration power that a simple cloth can block them, only Gamma is stopped with several inches of dense material (which includes lead, but also has alternatives). A few feet (yes feet not inches) of concrete can block gamma radiation too. When it comes to which is more harmful it would come down to which is a more common hazard/lesser dose to cause harm, which would be Lead. Radiation already exists in the background in non-lethal doses, whereas Lead can already be lethal with little exposure. Even the two other more ionising radiation's (Alpha and Beta) are easily deflected. Though constant exposure to high level radiation like X-rays, Gamma rays, and UV rays can cause cancer or other problems, but this takes either a lot of them at once or a significant after a consistent and long time. Though again do take my words with a grain of salt as I am not a professional. My source is my IGCSE physics book and Google. Anywho, I do hope this clears things up enough!
I actually like lead, for electrical solder at least, and for weights, matter of fact I am going to a melt down some lead, today, before weights for a mini hay rake, for behind a garden tractor.
Several yrs ago a gold smuggling operation was exposed after some of the idiots painting the gold to look like lead for easier international shipping got very ill, 2 died, authorities found out they had gold and lead particles in them and looked into it, the main crew were caught and 100s of lbs of gold recovered, the ring leaders had already left the US with several lbs of gold but if they come back they'll get a nice gov funded vacation in a federal facility for several yrs. Since gold and lead have very sim weight per given size they got away w this for a while but they didn't wear adequate protection and the lead entered their systems, the drs think this had been going on for at least 5 yrs. It's often little failures that expose such operations.
There is a big difference between lead the element and lead linked to an organic compound (i.e. something that contains carbon). The latter, a.k.a. organo-lead (e.g. tetraethyl lead, an old-timey gasoline additive for boosting octane level) is much more easily absorbed by the body than does elemental lead. This is the main way we breathe in lead.
Seems like yes. Damn, I may just have got lead poisoning in exchange for cheaper fishing weights I have never used but I'm gonna have to get it checked the next time something goes seriously wrong with me randomly and I have to go to hospital.
I do wonder if too much of it leads to cancer. I know because my father's father contracted lead poisoning and then leaukemia (coroner had the house tested and was alarmed)
Lead is a big part of the water crisis in Flint, Michigan. Lead pipes are still used for water today, but the pipes are often coated with some protective material, and the water is treated to reduce is corrosivity. When Flint changed their water source, the water wasn't adequately treated, causing a significant amount of lead to leech from the pipes into the water.
Ok lead...could you give a run down on mercury? I had constant low level exposure for four years in the lighting industry and I'm wondering if it adversely affected my mental health.

The 15 yr old was a normal kid until he was 6ish and ingested lead paint from in his home. He was the farthest behind in the class. :(
People often credit the scientific method with all sorts of things. But it turns out humans are pretty good at deducting things without it, hundreds of years before its existence.
Of course based on the same simple concept of reasoning.
Lead is devastating when 340gn flies through the body at 1400fps.
1400 frames per second? How are you rendering bullets that quickly?
What would that be a 45 70 or so
Analogous to why thallium is toxic .... inhibiting potassium ions in your biochemical functions.
Worked in a lead oxide facility for 6 years. Generally speaking, employee blood lead levels were around 20-25 (ppb?) (higher end for maintenance crew)
we used to bite lead weights onto fishing lines ...and I worked on a building site where some guys would chew lead ! Still that might explain a few things ….
I don't understand why it was still used in everything up until the last century when its harmful effects were known for so long.
Nobody knows why.
This could be a whole series Simon, I recommend why is mercury or arsonic bad next.
One of the better explanations. Good job! Keeping it succinct isn't easy since the stuff really does muck up everything it touches. biologically speaking. Will you also at some point cover some of the other "bad metals" we've learned about? I seem to recall reading somewhere that at the start of the Industrial Revolution, people were using discarded slag from mines as a kind of weed deterrant for their gardens - the specific mention I'm remembering described a family spreading copper tailings (I assume that means slag, right?) around their hedges to keep down the weeds and grass. Their small child got hold of one such bit of waste and - well the results were of course unfortunate.
So it'd be interesting to learn about the history of how we learned what not to put in our gardens and so on. Or even just "why is copper bad for the body" similar to this video.
When I first started driving in the late sixties you might see three gasoline pumps with one labeled ethyl. This was short for tetra ethyl lead. It was an inexpensive way to increase the octane rating. It was about this time it was decided that putting lead into the atmosphere probably was not a good idea and was then banned.
Sugar of lead! It's got 100% electrolytes so you know it's good for you!
It's what the plants crave!!!
Brawndo!!!
Its got electrolytes!
Idiocracy is a movie that should be seen by more people. Perhaps not on "movie night", but perhaps when you are in a coma or something! :P
If lead were known to be poisonous for several millennia, who got the stupid idea to use it for paint and piping?
It is cheap
The romans did!
(Also, a lot ot things were _incorrectly_ known to be poisonous for millenia, and vice-versa!)
Those aren’t stupid ideas, lead paint is one of the most durable, longest lasting types of paint, and it prevents wood from rotting. It’s extremely opaque so it can be spread thin without needing a second coat, and brushstrokes smooth out flat, allegedly. And lead pipes can be shaped and bent with just your bare hands! It’s abundant so it’s a no brainer why a person living two thousand years ago would use it for just about everything. If lead wasn’t toxic it would be EVERYWHERE, because it’s one of the most useful metals of all
not to forget putting it in your wine to sweeten it
@@Bloated_Tony_Danza It might be useful but it is harmful.
That's why OP asks if people were stupid.
Can you believe that people used it once as a gas and inhaled it in large quantities through almost 1 century?
Sometimes you have to stop to think about usefulness and start to think about effects it has on your body instead.
Great one Karl
Can lead from the metal in machinery like old sewing machines get airborne? I have 2 machines made in India. I tested the metal and lead is on every surface! and in the oil. I imagine it gets in the oil from parts moving and friction causing contamination of the oil. But this oil get on my hands, so I wear gloves now. But I really want to know if it can get into the air? How worried should I be. I have to use these machines, they are very specialised and very rare.
What about mercury? And which is more poisonous, mercury or lead? And I remember hearing that other metals can be used to bind to one of these heavy metals and reduce it's toxicity, but I can't remember whether it was lead or mercury and what metal binded it (cadmium?) If you know anything about that, please do tell.
Thanks sir for detailed information
Yeah, the most toxic substances to humans usually do end up being inhibitors of bodily processes or tricks the body into thinking it's another substance. I would've liked to have seen a few minutes why lead is toxic and yet a similar substance like Bismuth isn't toxic. Great video regardless.
deadly lead blood level is under 100ppb and to put that into perspective, pretty much every toxin blood level is measured in ppm because having a few thousand parts per billion is usually not a big deal. not with lead.
Thanx ☺
I am overload of lead and mercury thank you for give us advice and I will be more than appreciate how to get rid of this from your body
Great video!
I'm not sure about there being no acceptable lead level. I worked at a lead smelter and those that actually worked at or around the smelter had quarterly blood tests to make sure their levels were not climbing too high. Working that close to a lead smelter every day for hours means exposure is unavoidable. After about 9 months there I had my heavy metals checked and i had minimal exposure. Though the contracted janitor, who wasn't supposed to contaminated areas, did get lead poisoning. After a fire in the smelter break area, the workers had to use the general break area and they drug in lead dust on their shoes, which he then in he inhaled. He didn't know it, but they were supposed to clean that breakroom, but they didn't and they never told him not to clean it. He got deathy sick.
I have a friend from Cameroon and the dentist put LEAD tp fill his tooth.
... and that's why Flynt, Michigan is such a happy place.
When I worked at a automotive dealership, i always wore gloves when I balanced tires. Guys there called me a bitch, I would laugh it off, but be thinking, "well at least I wont have some type of blood cancer when I'm in my 40s or 50s.
BTW for those of you who don't know the counter weights that go on your car's rims to make them balanced are 100% lead.
I like that the human race has known how bad lead is since bc days and Flint was just like, "Eh, it's ok to let lead be in the water," for going on 6 years. I was able to move a year ago but I still have many of these symptoms with no clue when or if they will go away. My eye sight and hair loss seem to be permanent.
Me: I've to go home early
Boss: Why?
Me: today i found out has uploaded a new video
Boss: Take my car!
I still want to see about the time when people used to use "sweet lead" to sweeten food.
It's bad for EVERYONE: _"Plomo o Plata?"_
Never choose _"Plomo."_
That reference, I get it.
No Plomo
Illy take the cocaine and money and please.
_no, gracias, solamente enchiladas de carnitas y frijoles por favor_

Thanks !!
Isnt lead useful to protect against radiation? If I shield my house with lead walls against radiation, which is more dangerous the lead or the radiation?
I heard this too I want to know
Do take my words with a grain of salt.
There are many types of radiation that already exist everywhere, Alpha, Beta, and Gamma. The first 2 are too weak in penetration power that a simple cloth can block them, only Gamma is stopped with several inches of dense material (which includes lead, but also has alternatives). A few feet (yes feet not inches) of concrete can block gamma radiation too.
When it comes to which is more harmful it would come down to which is a more common hazard/lesser dose to cause harm, which would be Lead. Radiation already exists in the background in non-lethal doses, whereas Lead can already be lethal with little exposure. Even the two other more ionising radiation's (Alpha and Beta) are easily deflected. Though constant exposure to high level radiation like X-rays, Gamma rays, and UV rays can cause cancer or other problems, but this takes either a lot of them at once or a significant after a consistent and long time. Though again do take my words with a grain of salt as I am not a professional. My source is my IGCSE physics book and Google.
Anywho, I do hope this clears things up enough!
Lead in my bones, skin, and blood make me immune to radiation
Cheery as always. :)
Mr. I want to know, Is it dangerous or poison for human if .human inhale smoke that came out from burning graphite batteries?. Thank you
Don't forget that Sugar of Lead, made from Lead and Grape Skins, was one of the first Artificial Sweeteners.
Wow, that's not good
Are car batteries dangerous to handle .Will acid inside the battery seep out if case is not broken .
Answer at 3:25
I would also like to learn about Aluminium.
I actually like lead, for electrical solder at least, and for weights, matter of fact I am going to a melt down some lead, today, before weights for a mini hay rake, for behind a garden tractor.
I have a lot of plastic toys in my room, would bagging them would be enough to protect myself from lead?
Coming out of a gun barrel, lead definitely is dangerous 😨
So how about handling lead weights when fishing? Or when handling lead bullets?
Don’t swallow em
Thank you moderately bearded and glassed Simon of years past
Several yrs ago a gold smuggling operation was exposed after some of the idiots painting the gold to look like lead for easier international shipping got very ill, 2 died, authorities found out they had gold and lead particles in them and looked into it, the main crew were caught and 100s of lbs of gold recovered, the ring leaders had already left the US with several lbs of gold but if they come back they'll get a nice gov funded vacation in a federal facility for several yrs. Since gold and lead have very sim weight per given size they got away w this for a while but they didn't wear adequate protection and the lead entered their systems, the drs think this had been going on for at least 5 yrs. It's often little failures that expose such operations.
Was used way back in the past for hat making. Thus, you now know why the Mad Hatter was insane!
thought that was mercury
There is a big difference between lead the element and lead linked to an organic compound (i.e. something that contains carbon). The latter, a.k.a. organo-lead (e.g. tetraethyl lead, an old-timey gasoline additive for boosting octane level) is much more easily absorbed by the body than does elemental lead. This is the main way we breathe in lead.
Actual question. Would lead exposure leading to anemia mean that a blood test for anemia would show up negative if lead wasn't tested for?
Seems like yes. Damn, I may just have got lead poisoning in exchange for cheaper fishing weights I have never used but I'm gonna have to get it checked the next time something goes seriously wrong with me randomly and I have to go to hospital.
can you talk about How Harmless Aluminum is to the Human Body according to modern science ? Thanks
not as harmless as you might think...not as toxic as lead but don't go sucking on lozenges made of them either
Is that not good protection against radiation
I do wonder if too much of it leads to cancer. I know because my father's father contracted lead poisoning and then leaukemia (coroner had the house tested and was alarmed)
Lead is a big part of the water crisis in Flint, Michigan. Lead pipes are still used for water today, but the pipes are often coated with some protective material, and the water is treated to reduce is corrosivity. When Flint changed their water source, the water wasn't adequately treated, causing a significant amount of lead to leech from the pipes into the water.
Ok lead...could you give a run down on mercury? I had constant low level exposure for four years in the lighting industry and I'm wondering if it adversely affected my mental health.
Romans: Lead is bad.
Americans: lets popcorn all the ceilings and make gasoline with it.
Thinking I should store my guns and ammo somewhere other than my room from now on.
I am a metal detectorist and I find a lot of old lead. Some of it is Roman. It's never caused me issues. But then I don't suck on it or put it in my tea..
i am building a closed terrarium and want to place an old lead Plane from 1937 in it. Would it kill the plants and poison the soil ?
Can you do one of your Biographies on Florence Nightingale please
hey simon question for you why is there 7 days in a week? future possble video idea
