As TBBPA concentration found in
samples is most probably a consequence of its
application in acrylonitrile butadiene styrene (ABS)
plastic. This is supported by various studies that there
are at least 75 different types of commercially available
BFRs, of which 30-40 are widely used in EEE (Chen
and Wang, 2009). These flame retardants are totally
different components from PBBs and PBDEs.
