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.
Exposure to lead in gasoline during childhood resulted in many millions of excess cases of psychiatric disorders over the last 75 years, a new study estimates.
Lead was banned from automobile fuel in 1996. The study, published Wednesday in the Journal of Child Psychology and Psychiatry, looked at its lasting impact in the U.S. by analyzing childhood blood lead levels from 1940 to 2015. According to the findings, the national population experienced an estimated 151 million excess mental health disorders attributable to exposure to lead from car exhaust during childrenâs early development.
