I have a couple of nagging questions. Your help would be appreciated.

What does (do?) the dioxins decompose TO when exposed to UV? 

At what rate do they decompose? Do they decompose so effectively that it is
safe to emit them from power boiler stacks in pulp mills? (This is what a
Risk Assessment in British Columbia Canada suggested.)  

Secondarily, what does OCDD decompose to?
