Workplace air measurements are presented for PBDDs and PBDFs. These me
asurements were taken during extruder production and injection molding
of a PBTP-polymer blended with glass fibre, Sb2O3, and tetrabromobisp
henol 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 p
resented. No 2,3,7,8-substituted PBDDs and PBDFs could be detected. Th
e values monitored for the other isomers (tetra- to hexabromo-compound
s) were in the region of 30 to 260 pg/m3.
