Impact of Lead Exposure on Mental Health

Leaded gasoline has had lasting detrimental effects on public health, particularly impacting mental health in American children over the past several decades. Research indicates that around half of Americans born before leaded gasoline was banned in 1996 were exposed to harmful levels of lead during their childhoods. A recent study estimates that this exposure could be responsible for approximately 151 million cases of mental health disorders in the last 75 years, with the most significant effects seen in Generation X. While leaded gasoline is no longer in use, lead exposure persists in homes and communities, emphasizing the importance of blood testing and soil assessment for continued risks.
