What to know

  • Wildfire-related PM2.5 is substantially more harmful per unit of exposure than PM2.5 from other sources, responsible for 17% of mortality despite comprising only 4% of total PM2.5.
  • Wildfire smoke exposure is linked to higher hospitalization risks for cardiovascular and respiratory disease, and poorer survival rates among lung cancer patients.
  • As climate change intensifies wildfires, smoke increasingly affects regions far beyond traditional fire-prone areas, making this a growing nationwide public health concern.

    Research highlights wildfire smoke now affects tens of millions nationwide

    The studies emphasize that wildfire smoke increasingly affects communities far beyond traditional fire-prone regions across the United States, exposing tens of millions of people to elevated air pollution levels as climate change drives more frequent and intense wildfires.

    “Wildfire smoke is no longer a regional environmental issue. It is becoming a nationwide public health challenge.”

    Studies reveal wildfire PM2.5 accounts for 4% of exposure but 17% of mortality

    The Lancet Oncology study analyzing 414,016 lung cancer patients aged 65+ found that although wildfire-related PM2.5 represents only about 4 percent of total PM2.5 exposure, it is responsible for approximately 17 percent of mortality related to total PM2.5, with hundreds of annual deaths attributable to wildfire smoke exposure.

    “Our research shows that wildfire-related PM2.5 appears to be more harmful than equivalent levels of pollution from other sources.”
    — Dr. Yaguang Wei
  3. background

    Mount Sinai researchers publish studies on wildfire smoke health impacts — Two peer-reviewed studies led by Min Zhang and Yaguang Wei were published in Nature Communications and The Lancet Oncology, examining the long-term health effects of wildfire-related PM2.5 on cardiovascular, respiratory, and lung cancer outcomes.
