Due to their global distribution, potential persistence, bioaccumulation and toxicity most of the BFRs of the first Generation are banned or restricted, and replaced by new ones. However, based on similar properties these new compounds may also pose a serious risk by causing adverse effects to human health and the environment. These alternative BFRs were grouped into two classes: „novel” and „emerging” BFRs. Emerging BFRs are defined as compounds that have been identified in any environmental compartments whereas novel BFRs are only detected in materials and/or goods above 0.1 wt.-%. The environmental fate of these alternative BFRs is partially unknown. Over the past years a multitude of studies on the photodegradation of BFRs in environmental matrices have been conducted to assess the photochemical behavior and fate in the environment. The photolytic debromination reaction is particularly induced among BFRs by UV exposure. The novel brominated triazine-based flame retardant tris-(2,4,6-tribromophenoxy)-s-triazine (TTBPTAZ) (Table 1) is a BFR that is mainly used in acrylonitrile butadiene styrene and high impact polystyrene. Ballesteros-Gómez et al. detected TTBP-TAZ in 8 of 13 plastic parts of consumer products and in 9 of 17 indoor dust samples but the photochemical behavior and fate is not known until now. The results of the present study, focused on photodegradation processes were performed for the first time for TTBP-TAZ to identify the photolysis intermediates and products to assess the environmental fate.
