FORMATION OF HETEROCYCLIC HAZARDOUS COMPOUNDS BY THERMAL DEGRADATION OF ORGANIC COMPOUNDS
2,3,7,8-Tetrabromodibenzofuran in ppm concentrations can be generated via reductive debromination and subsequent intramolecular cyclization during thermolysis of polybrominated aromatic compounds such as decabromodiphenyl ethers which are used as flame retardants in plastics.The respective tetrabromobenzodioxin isomer is produced in moderate amounts.In analogy to the chlorinated isomers the formation of toxic substances from incineration or fire accident constitutes a potential hazard.
