Have they examined if it is the wood itself; or the (possible - no idea if true) accumulations of microplastics and other chemicals into the wood?

I would not be terribly shocked if we found out that wood is more dangerous to burn today than it used to be.

Edit: For the downvoters who think it’s unlikely, consider that microplastic and PFAS in rainwater has passed safe levels. What do trees grow from?
