Gasoline used to be a common source of lead exposure in the US. Now, millions of people’s mental health may be feeling the impacts.

Exposure to car exhaust from leaded gas, which was phased out in 1996, resulted in anxiety, depression and ADHD symptoms in generations of people, researchers found.

Decades of leaded gasoline exposure in the United States linked to mental health conditions such as depression, anxiety, ADHD and neurotic behavior.

A new study published in the Journal of Child Psychology and Psychiatry has calculated that millions of Americans are dealing with mental disorders attributable to childhood lead exposure—through exhaust from cars fueled with leaded gasoline.

A new study revealed that leaded gasoline exposure may have contributed to millions of mental health cases in the U.S.

The fuel type was banned in 1996, but people exposed to it as children are particularly susceptible to depression, anxiety, ADHD and personality changes.

The addition of lead to gasoline in the United States was responsible for 151 million cases of psychiatric disorders such as depression, anxiety, and hyperactivity among Americans, a new study concludes.
