What’s Hidden in Our Past? How Leaded Gasoline Contributed to 150 Million Mental Health Cases!
- Replies 0
For many, the sound of car engines starting up and the smell of gasoline brings back memories of a simpler time—an era of progress and mobility. But beneath the surface of the post-World War II boom, there was something far more troubling at work.
Lead, a substance once added to gasoline to improve engine performance, has left behind a legacy that we’re only now beginning to fully understand. A recent study has revealed that childhood exposure to leaded gasoline has contributed to over 150 million cases of mental health disorders in the United States.
If you grew up during the height of leaded gasoline use, this information might hit close to home. The study, published in the Journal of Child Psychology and Psychiatry, paints a sobering picture of the lasting impact lead exposure has had on public health and individual well-being.
Lead was added to gasoline in the 1920s to prevent engine knocking and improve performance, and its use skyrocketed after World War II. By the mid-1960s to the mid-1970s, leaded gasoline was at its peak.
But many who grew up during this time had no idea that the air they were breathing was laced with a dangerous neurotoxin.
Researchers from top institutions, including Duke University and the Medical University of South Carolina, analyzed childhood blood lead levels from 1940 to 2015.
The results were eye-opening: an estimated 151 million excess cases of mental health disorders—including depression, anxiety, and attention deficits—could be traced back to lead exposure from car exhaust.
The effects of lead on mental health are more serious than we may have realized. The study found that lead exposure not only increased the risk of psychiatric disorders but also negatively affected impulse control and heightened neurotic tendencies.
Generation Xers, especially those born between 1966 and 1970, were hit hardest, as they were born during the peak years of leaded gasoline consumption.
Aaron Reuben, a co-author of the study and a postdoctoral scholar in neuropsychology, explains that while we can’t reverse the damage caused by lead exposure, this research emphasizes how important it is to continue environmental health efforts.
The phase-out of leaded gasoline in 1996 was a significant step forward, but this study serves as a harsh reminder that the damage has already been done for millions.
Even though lead was banned from gasoline and paint, it hasn’t completely disappeared from our environment. You can still find it in some imported toys, old water service lines, certain soils, and the paint of older homes.
According to the Centers for Disease Control and Prevention (CDC), there’s no safe level of lead exposure—just a small amount can cause developmental and learning issues, particularly in young children.
The study combined historical blood lead level data with previous research, including a 2019 study that tracked children exposed to lead in New Zealand and their mental health outcomes over three decades.
The evidence is clear: lead exposure has had a lasting, negative effect on mental health at a population level.
Rather than causing panic, this study should encourage action. Dr. Lisa Fortuna, chair of the American Psychiatric Association’s Council on Children, Adolescents, and Their Families, praised the research for bringing attention to the role of environmental toxins in the rise of mental health issues.
While we’ve made strides in reducing lead exposure, it’s crucial that we stay vigilant. Lead screenings for young children are now recommended, and treatments like chelation therapy can help remove the toxin if necessary.
We’re moving in the right direction, but there’s still work to be done.

The Psychological Toll of Lead
