According to the 100% acurate and never wrong Chat GPT

2,3,7,8-Tetrachlorodibenzofuran (TCDF) is not naturally present in trees or wood. It is a byproduct of the combustion process, particularly when wood or other organic materials are burned in the presence of chlorine or chlorine-containing compounds. TCDF belongs to a group of toxic compounds known as dioxins and furans, which are produced when chlorinated materials are burned at certain temperatures.

In wood combustion, the presence of chlorine (from treated wood, certain environmental pollutants, or contaminants in the wood) can lead to the formation of these compounds. The specific structure of TCDF forms during combustion due to the interaction of chlorine with organic molecules in the wood under high temperatures.

So, TCDF is a result of the combustion process rather than a component of the tree itself.

And followup:

is chlorine typically used in treating wood?
ChatGPT said:
Yes, chlorine-based compounds have historically been used in some wood treatments, although their use has become more restricted over time due to environmental and health concerns.

So uh don't burn wood scraps from old houses I guess.

Probably just combustion byproduct in general.
