title: A novel brominated triazine-based flame retardant (TTBP-TAZ) in plastic consumer products and indoor dust.
abstract: The presence of a novel brominated flame retardant named 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine (TTBP-TAZ) is reported for the first time in plastic parts of consumer products and indoor dust samples. TTBP-TAZ was identified by untargeted screening and can be a replacement of the banned polybrominated diphenyl ethers. Analysis techniques based on ambient mass spectrometry and on liquid chromatography with atmospheric pressure chemical ionization combined with high resolution time-of-flight mass spectrometry were developed for the screening, detection and quantification of this low volatility and high molecular weight compound. TTBP-TAZ was present in 8 of 13 plastic parts of consumer products (from mainly electric and electronic equipment acquired in 2012) at estimated concentrations of 0.01-1.9% by weight of the product (%, w/w). It was not present in any of the older 13 plastic samples that were collected in a recycling park (manufacture date before 2006), this suggests a recent use of TTBP-TAZ. It was also found in 9 of 17 house dust samples in the range of 160-22150 ng g(-1), with the highest levels being found in samples collected on electronic and electrical equipment. These preliminary results highlight the need for further research on TTBP-TAZ and the potential of using alternative analysis methods for the identification of new flame retardants.
