Here's an interesting study, published today:

"Coarse particulate matter (PM2.5–10) in Los Angeles Basin air induces
expression of inflammation and cancer biomarkers in rat brains."
https://www.nature.com/articles/s41598-018-23885-3

What is interesting is that, even with long term exposure, they only found
the specific biomarkers in PM2.5-10 (coarse PM), but not in ultrafine PM
(<0.15 um) or fine PM (<2.5 um).
90% of wood smoke PM is smaller than 1 um.
