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.
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.
