Researchers have linked lead exposure from childhood to higher rates of depression, anxiety, ADHD, and neurotic behavior among members of Generation X. A study published in the Journal of Child Psychology and Psychiatry found that years of exposure to leaded gasoline during development made this generation particularly vulnerable.
The study measured health survey and gas use data to estimate the amount of lead in people from 1940 through 2015 and linked it to an estimated 151 million excess mental disorders in the United States over a 75-year period. The researchers noted that the estimates should be considered a floor, as they only account for lead exposure from gasoline.
Lead can disrupt children’s brain development, fine motor skills, and emotions, leading to behavioral problems, loss of IQ, and attention deficit disorders. Those born between 1966 and 1986 had higher mental illness levels linked to lead exposure, with rates peaking for those born between 1966 and 1970.
Lead was added to gas in the mid-20th century to improve engine performance and eliminate engine knocking. However, its use tapered off in the mid-1970s due to damage to catalytic converters. The study found that peak lead use coincided with increased demand for psychiatric care and higher rates of juvenile delinquency.
The findings have significant implications for understanding the mental health crisis faced by Generation X. As lead is no longer a common pollutant, it’s essential to consider its historical impact on this generation’s health.
