Prenatal ozone: a silent culprit in the battle against childhood obesity

Prenatal exposure to ozone is increasingly recognized as a potential risk factor for childhood obesity, with significant implications for public health. A new study investigates the association between ozone levels during pregnancy and the growth trajectories of children, offering insights into the early-life origins of obesity. The research found that a 10 μg/m³ increase in ozone concentration during pregnancy significantly raises BMI, weight-for-age, and weight-for-length Z scores in children. This exposure is linked to accelerated BMI gain and higher obesity risk in early childhood, highlighting the urgent need to address air quality to protect children’s health.

Alzheimer’s Disease: Making Connections between Air Pollution and Neurodegeneration

Exposure to urban air pollutants such as ozone (O3) is increasingly linked with Alzheimer’s disease; yet because ozone cannot travel from the lungs to the brain, the mechanism by which it contributes to development of Alzheimer’s has been poorly understood.…

Energy Regulation Rollbacks Threaten Progress Against Harmful Ozone

The fight against harmful ozone is under legal threat. Air quality and carbon emissions regulations are currently in limbo in courts and congress, from core legislation from the 1970s to rules from the last U.S. administration. This study models the future losses in the fight to drive down respiratory-damaging, ground-level ozone if the regulations go away.
