Wildfire-specific particulate matter 2.5

1. Wildfire-specific particulate matter 2.5 is associated with laryngeal cancer in humans (cRR 1.13 (95% CI 1.07–1.19) per additional exceedance day).

   “laryngeal cancer exhibited the largest effect, with a cRR of 1.13 (1.07-1.19) per additional exceedance day over a 10-year lag period.”
