75 Years of Lead in Gasoline Caused 150 Million Mental Health Disorders, Study Finds (usatoday.com) 212

The use of lead in gasoline "might have harmed the mental health of a generation," reports USA Today. Gen X bears an extra burden of conditions such as depression, anxiety, ADHD and neurotic behavior because of the leaded gasoline they were exposed to as children, according to a study published Wednesday in the peer-reviewed Journal of Child Psychology and Psychiatry. Leaded gas was banned in the United States in 1996, but the study said years of exposure during development made them particularly vulnerable.

Lead gas peaked from the mid-1960s through the mid-1970s, and children born during that era would later develop some of the highest rates of mental health symptoms, the study said. The study also linked leaded gas to "disadvantageous" traits, such as struggling to concentrate, stay on task or organizing thoughts. "I tend to think of Generation X as 'generation lead,'" said Aaron Reuben, a study co-author and assistant professor of clinical neuropsychology at the University of Virginia. "We know they were exposed to it more and we're estimating they have gone on to have higher rates of internalizing conditions like anxiety, depression and symptoms of attention deficit hyperactivity disorder...."

Researchers linked the lead exposure to an estimated 151 million "excess mental disorders" in the United States over the 75-year period. The estimates should be "considered a floor" because it relies mainly on gas and not exposure from lead in paint and pipes, Reuben said... Those born between 1966 and 1986 generally had higher mental illness levels linked to lead exposure with the rates peaking for those born between 1966 and 1970, the study said. Those rates coincided with the peak use of lead in gas from the mid-1960s through the mid-1970s... The study said the peak lead use coincided with increased demand for psychiatric care and higher rates of juvenile delinquency.

Today there's routine blood screenings for high levels of lead, study co-author Reuben says. But in the 1960s, 1970s, and 1980s, "folks were walking around with an average blood lead value that today would trigger clinical follow-up."

      Urban dwelling isn't a bed of roses either. While the results of the experiment do not necessarily translate directly to human behaviors, there was a study done with rats [wikipedia.org] where they were given a high population density "utopia" to live in. Basically, all their needs were provided for and you'd assume that would've just lead to a bunch of really contented rats going about their little ratty lives. Well, nope. The entire rat colony collapsed. Also, before the society collapsed, the rats began acting very weird.

      Car culture certainly brought with it its own share of problems, but you have to figure that if people are willing to tolerate all the infrastructure and scalability issues inherent to private vehicle ownership just to avoid living in the city, perhaps there's a grain of truth in that old rat experiment. Besides, just the thought of having to tolerate living in some tiny condo downtown, and attempting to bring all my groceries home in a backpack while riding on a Bird scooter - yeah that'd be enough to drive me crazy.

      • You don't need to "drive-everywhere" in order to not be high population density.

        Humans are also not rats, and Freedman's work seems to indicate it's a social density not a population density problem. You can have high population density without an equivalent increase in social interactions - modern order food with an app and have it appear at your doorstep without seeing another human being makes that even easier than in the 60s and 70s.

        Midgley has been called a one man environmental disaster. Especially since he gave himself lead poisoning from working with tetraethyl lead.

        His infamous washing of his hands with leaded gasoline, and inhaling it place under his nose for a full minute, was supposed to prove how safe it was.

      It could also have something to do with the fact that these days we take mental illnesses more seriously. We make more treatments available and encourage people to seek treatment earlier rather than waiting until it's almost too late then treating them like a pariah.

      Likely to be a combination of many factors, leaded fuels included. Although I do have to wonder if private pilots have higher rates of mental illnesses as AvGas (Aviation Gasoline) for small piston engine planes can still be leaded.

      It was in 1969 that the effects of tetraethyl lead were shown to be damaging to children, damaging their impulse control and lowering their IQ.

      The alarm was sounded after many prisoners were tested and found to have high levels of lead. Then where they spent their youth was mapped out. And a huge number of them were living beside busy highways as children. https://ourworldindata.org/lea... [ourworldindata.org]

      Now so often people here like to claim correlation is not causation, but the evidence was strong enough to start the process of eliminating leaded fuel.

      Now to the subject at hand - that lead is another part of GenX's litany of woes.

      The same should be said for Baby Boomers, and the Greatest Generation. Those WW2 airplanes were using 130 Octane gasoline, courtesy of lead. They used to wash their hands with it.

      Don't forget the tasty sweet lead acetate paint chips - long a favorite of little kids.

      Lead does indeed harm the hell out of children, but tetraethyl lead poison knows no age restriction. Horrid stuff.

      So the concept of naming GenX'ers as generation lead seems a little off, given that we were putting tetraethyl lead in fuel since the 1920's, and neurological effects were well known by 1943. So we're looking at a problem that spans from The Silent Generation, the Greatest Generation, the Baby Boomers, and GenX.

      Since biology hasn't changed, the effects should be the same. And they are. Bad stuff, and has been a problem over multiple generations.

    Thomas Midgley Jr. [wikipedia.org] was the man responsible for leaded gas in the first place. If that wasn't bad enough, he's also responsible for creating the refrigerants which lead (pun intended) to ozone depletion. The Wikipedia article mentions that he's referred to as "one-man environmental disaster". Considering that he gave low-level lead poisoning to entire generations, that's a bit of an understatement.

    The worst part about all this is that the dangers of lead have been known since the time of ancient Greece. It's also why I strongly doubt that we're ever going to make things right in regards to climate change, because humanity has a terrible track record of getting off the wrong path even when we know it's the wrong path.

        The irony is, leaded gasoline solved an even earlier major health issue in cities... Diseases from animal waste, notably TB.

        By the end of the 19th century, London had to deal with 20 tons of horse shit a month. So did all major cities of the age.

      Just FYI, Freon is non-toxic, non-combustible and non-explosive.

      None of the replacements have all three of those properties. Many of them don't have any. Your next furnace is going to cost about $1000 more because it needs sensors to detect leaking propane (used as a refrigerant by the next generation of air conditioners) before it blows your house up.

      • by Powercntrl ( 458442 ) on Friday December 06, 2024 @08:40AM (#64995405) Homepage

        The only place you're going to find propane (or more likely, isobutane) used as a refrigerant in the USA is in small office/dorm room mini-fridges. The EPA places limits on how much flammable refrigerant is legally allowed to be charged in an appliance. The latest refrigerant that the US HVAC industry has largely been coalescing around for comfort cooling/heating is R-32. It's slightly flammable, but isn't anything particularly new or scary, because it already makes up 50% of the commonly used R-410a refrigerant. It's also worth a mention that R-410a is a zero ozone depletion refrigerant - it's only being phased out for its high global warming potential. Older refrigerants such as R-12 and R-22 were phased out because their chlorocarbon formula was damaging to the ozone.

        There is a bit of a push to replace furnaces with heat pumps anyway, for reasons of increased efficiency and reduction of fossil fuel use. Heat pumps don't have the issue of a source of ignition being near any potential refrigerant leaks. The part you are correct about is that any way you slice it, a replacement HVAC system is going to require that you open your wallet a bit wider than in the past. Mostly it's because of the increased costs of manufacturing HVAC equipment (and that's been going on with everything since Covid), and the rest is just increased labor costs.

        Finally, yeah, freon was a "miracle chemical" when it was initially discovered. Ammonia was nasty stuff, but ironically, you can still buy small absorption refrigerators on Amazon even today. They're still in use by the Amish and in RVs. Large commercial refrigeration facilities also commonly still use ammonia.

      • Just FYI, Freon is non-toxic, non-combustible and non-explosive. None of the replacements have all three of those properties.

        When was the last time you heard of a refrigerator exploding? Oh, right: never.

        The chlorine-containing HFCs ("Freons") that deplete ozone were phased out, but other compounds have taken their place. R134A is the most commonly used right now, but pretty much all of the currently used replacements for the old freon refrigerants are non-toxic, not-combustable, and non-explosive.

      • Your next furnace is going to cost about $1000 more because it needs sensors to detect leaking propane (used as a refrigerant by the next generation of air conditioners) before it blows your house up.

        Why would that apply to propane refrigerant and not a furnace with an already unlimited natural gas supply?

    Most X generation children's parents were either bought up by the Silent generation, who grew up during WW2, or the oldest boomers whose parents also fought in WW2, Korea and Vietnam. Those soldiers bought a lot of mental health issues back from war before becoming parents. Traumatized parent == traumatized children and back then, less was known about those affects on the mind than the effect of leaded fuel on the brain.

    One song describes it perfectly. [youtube.com] and I still think we have a fair way to go before we unwrap all of the mental health issues that the X generation has had to deal with.

    Given the time frames, why the constant mention of Gen X? They were the latter half of that, yet there is no mention of the other half?

    Gen X is classically the period between 1965 and 1980. Gen X didn't even start until the peak, according to this. How about the first half?

    Also, from here: https://www.epa.gov/americasch... [epa.gov].

    "The largest declines in blood lead levels occurred from the 1970s to the 1990s, following the elimination of lead in gasoline. "

    So the bulk of Gen X was situated during the LARGEST DECLINE in blood lead levels, how about talking about the biggest victims of lead poisoning then? Not Gen Xers, they were the first to benefit from unleaded gas.

    And Gen X/Boomer has never even been a good division anyway. Boomer and Gen X are largely the same, but there's a group between them that are significantly different. Technically, Generation Jones is the right group here. https://en.wikipedia.org/wiki/... [wikipedia.org]

    "Researchers linked the lead exposure to an estimated 151 million "excess mental disorders" in the United States over the 75-year period."
    75 years! Generations are more like 15 years.

    "Those born between 1966 and 1986 generally had higher mental illness levels linked to lead exposure with the rates peaking for those born between 1966 and 1970, the study said."
    Oh and now it's a 20 year period, and it's compared to a period entirely within it!

    "Those rates coincided with the peak use of lead in gas from the mid-1960s through the mid-1970s... The study said the peak lead use coincided with increased demand for psychiatric care and higher rates of juvenile delinquency."
    It also coincided with some other important issues. A big recession, Vietnam, Watergate, corruption of the Republican Party, Iranian revolution, the first time in the country's history when the outlook for children was worse than for their parents. ALL the things that defined the difference between Gen Jones and the Boomers. Gen X, once you separate out Jones, is a period defined by Reagan, where the outlook, for a time, improved considerably and restored attitudes similar to those of older boomers. And all these groups had significant exposure to lead, and all are vilified today as having it good compared to younger generations.

    This article has an agenda and is not aligned with, or particularly aware of, actual history. Why it feels the need to play identity politics is very interesting. The world is very aware of the danger of lead, how about an article about the interesting dissonance of these peak mental issues with Reagan's dismantling of mental care? What we have here is cherry picking and crappy history. Not sure what the point is.

    Also, are "depression, anxiety, ADHD and neurotic behavior" higher in Gen X than today? Seems unlikely, although that's probably cultural.

  • Wow, that's like 10% as much as Tik Tok!
  • Inhaling lead is obviously bad, and one wonders that such an additive was ever approved. People have known about lead poisoning for a long time. One knew about neurological risks to children already in the 19th century! How did anyone think that putting lead into the air was an acceptable idea?

    However, I do question the "150 million" cases in the US. They say this is centered on people born from 1966 to 1986. However, even if you count all births from 1960 through 1996 (when leaded gasoline was outlawed),

  • Other things were happening at the same time as the rise / fall in lead levels. In particular high lead levels occurred during the height of the cold war, potentially a huge source of stress for children.

    There is lots of evidence that lead in the air is bad, and eliminating lead from gasoline was a very positive move, but I don't think there is a straightforward way to demonstrate the level of harm caused by lead because so many other things correlate with lead exposure.
