Wood rotting naturally by fungal action also releases dioxins. There is no
free lunch. Pristine woodlands actually have detectable levels of dioxin
from natural sources (with or without recent forest fires).

It comes from the way fungal enzymes attack lignin in wood...

Any chance of some type of link to this?

I can't see anything that I would trust in the free to view zone.

Google: natural fungal dioxins

Will get you some stuff but I don't trust Eurochlor any more than I
would trust the ban all synthetic chemicals brigade.

I was under the impression that fungal action was one way of degrading
dioxins into non toxic materials.

They can do either. There are lots of fungi but only a few have enzymes
that can break down aromatic chlorine compounds!
