Phys.org: Eaton Fire may have exposed nearly 7 million people to elevated lead levels, by California Institute of Technology
From the article: “For context, the scientists note that since the early 1980s, when leaded gasoline was being phased out in Los Angeles, typical concentrations of lead in the Los Angeles Basin have declined by more than two orders of magnitude, or by about 99%. So while the spike in lead values is dramatic compared with current baselines, it was in line with what was normal before the 1980s.”
