@Denny Oh, yes, plenty. Main ones of concern are/were benzene and naphthalene, but so many others, too, a whole cocktail including asbestos, cyanide, heavy metals, as well as particulates. We've just been fobbed off and told it's not harmful, it's below legal limits, and it's all in our heads (we're crazy!). A bit of digging showed that even low level exposure to benzene, etc. can be harmful if it's over a long period, they rigged the stats, and our local elected representatives were wined and dined by the developers in the south of France.

Just saw video of your nearby fire and that does look scary. I'd say your guess is probably right!
