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.…

New mechanism links ozone and disease resistance
Scientists have identified a new mechanism for the breakdown of the building blocks of cell membranes. The mechanism is based on autoxidation from the interaction of oxygen and hydroxyl free radicals and the subsequent chain reaction between hydroxyl radicals and the Criegee intermediates that form from atmospheric ozone.
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.
