I have a rather old, but I believe still up to date list of toxins and
furanes given off by burning FR4 resin systems based on TBBA-EP /
Dicyaniamide. The list was compiled during Thermolysis Studies with
Brominated Epoxy Resins at various temperatures by Dr. Kugler Ciba-Geigy AG
(presented at EIPC Zurich 1987). I'd be happy to forward this on to any
interested parties. Please mail me off-line.

to have this problem. Though I do know it is seen with other flame
retardants.  Do you any details?
