Abstract
Workplace air measurements are presented for PBDDs and PBDFs. These measurements were taken during extruder production and injection molding of a PBTP‐polymer blended with glass fibre, Sb2O3, and tetrabromobisphenol A carbonate oligomer. The extruder granulate and the molded test articles were also analyzed. The sampling trains, technique and plans, as well as the preparation, clean up and determination methods are presented. No 2,3,7,8‐substituted PBDDs and PBDFs could be detected. The values monitored for the other isomers (tetra‐ to hexabromo‐compounds) were in the region of 30 to 260 pg/m3.
