Early-life exposure to car exhaust from leaded gas reduced the IQ of around 170 million Americans, a new study reports.
The effects of lead exposure on overall health have been well document, but a new study reveals early exposure to pollution can have a detrimental effect on personality. Researchers report those who were born following the decline of environmental lead levels had more mature personalities and were more conscientious and less had lower levels of neuroticism than those born in generation with higher lead levels.
Early-life exposure to atmospheric lead was associated with less mature and less healthy personality traits in adults.
Elevated levels of lead in the blood of children was associated with structural changes in the brain during mid-life. Those with higher levels of lead exposure as children had decreased hippocampal volume and structural deficits in white-matter integrity.
Low-level exposure to lead during development does not lead to alcohol use disorder, but does alter the neural circuits in a way that if addiction occurs, it makes it harder to refrain from returning to addiction related behaviors.
Children raised in areas with a high risk of lead exposure have decreased brain volume and problems with cognitive performance.

Higher levels of lead in topsoil have been linked to an increased risk of cognitive impairments, learning difficulties, and problems with decision making in 5-year-old boys.
A new study reveals lead exposure during childhood can significantly impact mental health and personality traits later in life. Researchers found exposure to leaded gasoline prior to the 1990s was linked to increased psychiatric symptoms experienced by adults.
A new study looks at the long term ramifications of childhood lead exposure, finding links to lower cognitive function, IQ and socioeconomic status.
