TY - GEN A1 - Lörchner, Dominique T1 - Phototransformation of the “emerging” BFR 1,3,5-Tris-(2,3-dibromopropyl)-1,3,5-triazine-2,4,6-trione N2 - The occurrence and fate of brominated flame retardants (BFRs) in the environment are topics of increasing concern. In recent years, numerous studies about their global transport, UV degradation, bioaccumulation and toxicity were performed to assess their environmental fate. As a result, most of the first generation BFRs 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. According to the European Food Safety Authority (EFSA) the class of the “emerging” BFRs are defined as compounds that have been identified in any environmental compartments, but the potential for degradation or bioaccumulation of these emerging BFRs is partially unknown. A representative of this class of compounds is the heterocyclic TDBP-TAZTO which was first detected in mollusks from Chinese bohai sea and in environmental matrices near a manufacturing plant in southern china. Furthermore, Wang et al. describe that the growth of the alga Nannochloropsis sp. is inhibited by TDBP-TAZTO in a concentration dependent manner but the photo-chemical behavior as well as the formation of possible photo-transformation products (PTPs) are still unknown. In order to clarify this complex issue photo-degradation experiments were by determining the rate constants and degradation half-life times of TDBP-TAZTO in different solvent compositions. In this study, the photodegradation of TDBP-TAZTO was performed for the first time to identify its photolysis products and to get a first understanding about the main degradation pathway in environmental matrices.
