It's widely known that wildfire smoke is bad for your health, but a group of researchers recently found a known carcinogen in California wildfire ash, raising concerns about just how harmful it could be to breathe the air near a blaze.
According to a study released in Nature Communications last week, researchers discovered dangerous levels of hexavalent chromium in samples of ash left behind by the Kincade and Hennessey fires in 2019 and 2020.
