Let It Burn!

Abstract​


Background​

More than half of the current US population was exposed to adverse lead levels in childhood as a result of lead's past use in gasoline. The total contribution of childhood lead exposures to US-population mental health and personality has yet to be evaluated.

Methods​

We combined serial, cross-sectional blood–lead level (BLL) data from National Health and Nutrition Examination Surveys (NHANES) with historic leaded-gasoline data to estimate US childhood BLLs from 1940 to 2015 and calculate population mental-health symptom elevations from known lead-psychopathology associations. We utilized five outcomes: (1) General Psychopathology “points”, reflecting an individual's liability to overall mental disorder, scaled to match IQ scores (M = 100, SD = 15); (2) Symptoms of Internalizing disorders (anxiety and depression) and Attention-deficit/Hyperactivity Disorder (AD/HD), both z-scored (M = 0, SD = 1); and (3) Differences in the personality traits of Neuroticism and Conscientiousness (M = 0, SD = 1).

Results​

Assuming that published lead-psychopathology associations are causal and not purely correlational: We estimate that by 2015, the US population had gained 602-million General Psychopathology factor points because of exposure arising from leaded gasoline, reflecting a 0.13-standard-deviation increase in overall liability to mental illness in the population and an estimated 151 million excess mental disorders attributable to lead exposure. Investigation of specific disorder-domain symptoms identified a 0.64-standard-deviation increase in population-level Internalizing symptoms and a 0.42-standard-deviation increase in AD/HD symptoms. Population-level Neuroticism increased by 0.14 standard deviations and Conscientiousness decreased by 0.20 standard deviations. Lead-associated mental health and personality differences were most pronounced for cohorts born from 1966 through 1986 (Generation X).

Conclusions​

A significant burden of mental illness symptomatology and disadvantageous personality differences can be attributed to US children's exposure to lead over the past 75 years. Lead's potential contribution to psychiatry, medicine, and children's health may be larger than previously assumed.

Wait... Leaded gasoline was banned 50 years ago in the US. There were partial bans stretching back another 20 years. Another bullshit study that used methodology to fine and try to prove a preformed conclusion if you ask me. The mentally ill here are those producing these useless, self-serving, studies.
 
A study published Wednesday revealed that gasoline containing lead was the direct cause of 150 million cases of mental illness in the United States.

The study published in the Journal of Child Psychology and Psychiatry indicated that lead exposure had a far greater effect on the mental health of Americans than previously thought.

“Mental health in America was likely significantly influenced by Americans’ exposure to lead over the past century,” Aaron Reuben, a co-author of the study and a postdoctoral scholar in neuropsychology at Duke University and the Medical University of South Carolina, told the Washington Examiner.

The study examined blood levels of children between 1940 and 2015, and researchers found that those born between 1955 and 1986, Generation X, had the highest correlation of mental illnesses or personality disorders with high lead blood levels.

People born between 1966 and 1970 had the highest burden of mental illness, which coincided with peak leaded gasoline in the mid-1960s and mid-1970s.

Previous studies have shown that lead exposure results in lower IQ levels and neurological problems. Reuben found that over half of Americans have lowered IQ levels thanks to lead exposure. Those under the age of 6 are most prone to the detrimental effects of lead poisoning.

In 1996, regulators banned the use of leaded automobile fuel, years after lead’s negative effects became known. Lead-based paint was banned nearly 20 years earlier, in 1978. There is no safe level of exposure to lead, according to the Centers for Disease Control and Prevention.

Lead may still be found in old water pipes, old houses, and some toys imported from foreign countries. Reuben said lead poisoning is still a problem. Approximately 500,000 children in the United States have elevated levels of lead exposure every year.


“Our chief exposure concern is to old leaded paint that has exfoliated inside old homes and outside into soil around homes, but there are still so many sources of lead, including in consumer foods and products,” Reuben said. “Estimates suggest one in four households in the US have soil lead hazards that warrant attention.”

While lead exposure is an ongoing problem, the study found that children born around 2015 had the lowest level of mental illness cases due to lead exposure.
 
The Federal government has mandated the removal of all lead water pipes, which they claim will cost about $50 billion, which means it is prob more like $200 billion....these so called studies are likely top cover.

This claim about lead gas is the kind of thing that Bret and Heather often talk about...Heather especially likes taking apart junk science.

I will report back if I hear anything.

What about the 4 centuries lead was used to store food in cans, within public water systems, paints on toys, etc. not just gasoline which worked as a lubricant on valves.

Two important points:

1. YOU lack the necessary skill to critique the methods (none of which you actually understand and no details are available to you because this article is behind a paywall), so your critique is likely null from the outset

2. If you read the first paragraph of the summary you will note that more than 50% of the US population that is currently here has had exposure to leaded gasoline. I know I have and I'm only 61. I had it for about the first 20 years of my life.

Given that Pb can be expected to be a long-lasting impact on mental development it is PERFECTLY RATIONAL for effects to still be felt within our society to this day.


In other words: You are probably full of shit as you usually are when faced with debating against science.

Wrong! I have considerable skills in statistics and am particularly proficient in regression analysis both linear and exponential.

This is extrapolated and even if it is 100% accurate, it doesn't mean that someone was exposed at some level that was highly dangerous.

Given that the sort of researchers that produce these studies usually tend towards over-estimating the danger of stuff and take an approach that maximizes risk, I'd still say they're full of shit. But that's how they get paid more to research this stuff because bureaucrats then get to use their flawed analyses to make more onerous regulations giving them more power, money, and control.

No you don't.

WHAT is "extrapolated"? And are you trying to make a comment on sample size? Is that it?

Given that the sort of researchers that produce these studies usually tend towards over-estimating the danger of stuff

This is how I know you don't understand the science you are critiquing. You start by simply making blanket accusations without any evidence and based on some caricature of science. Not even serious.

and take an approach that maximizes risk, I'd still say they're full of shit.

If you actually DID understand statistics as you claim I'm guessing you would have by now introduced a point about statistics that didn't sound like you are just stringing as many impressive sounding words like "maximizing risk" as you can cobble together.

But that's how they get paid more to research this stuff

Sigh. And ANOTHER tell that you have NO CLUE about how all this works. God. I guess it is an indicator that the field YOU work in is made up of grifters and thieves who lie to get money.

because bureaucrats then get to use their flawed analyses to make more onerous regulations giving them more power, money, and control.


Wrong.

Yeah, I'm right. You don't even come CLOSE to having a CLUE how to interpret this data let alone critique it.

As per usual my instincts on this sort of thing are pretty good.

If you ban leaded gasoline on January 1, 1972, it doesn't mean all anthropomorphic lead is purged from the environment the next day on January 2. I don't know how long lead persists, but discharges of lead emissions undoubtedly ended up persisting for some time in soils, lakes, reservoirs, vegetation, airborne particulate matter.
 
Been saying for years that, among other things, Boomers had leaded gas brains. Always nice to know I'm right (again).
Watch what you say because I am a Boomer and I don't have anything to do with the people who on the
'LEFT have leaded brains. But, being the highly intelligent Boomer Conservative that I am, I will say that
those most likely having some form of mental deficiency are all on the political Left, especially the liberal
women that I showed from a map that just about 50% of them suffer from some form of mental depravity.
Now, I can't honestly say that these liberal mental midgets got their serious mental decline from being
around lead, but I'm quite sure that their mental decline was caused by them abiding by their liberal/
anti American or Communist ideologies. Hopefully these libs will get the care they need by crossing over
to join the pro American Republican Party.

LOL. Poor boomer doesn't wanna be blamed for what the boomers did. So sad. Run away little beta! Run! Find your "safe space"!

LOL. Sorry Libhater, you are painted with the same brush we all are painted with. YOU enjoyed all the same benefits we enjoyed. WE were the generation in charge that started the trend of life-long academic debt and unaffordable housing! WE ARE THE BANE OF THE NEXT GENERATION'S EXISTENCE!

LOLOL. We sucked too hard on the teat of what the country could offer and left 'er dry for the next folks. You can't run away from it. Your lips were wrapped around that teat too!

I'm not reading that Boomer drivel. Your entire generation is the worst in all human history.
