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.
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.
Go down some lead and get back to us about the scientism.Smells like scientism....ideology packaged as science.
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.

It's more like activism. That's where you have people who latch onto a cause and then produce "science" and "studies" that purportedly justify their activism.Smells like scientism....ideology packaged as science.

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,
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.
Wrong.
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.Wait...

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 theBeen 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.
