Abstract The presence of emerging contaminants in aquatic environments is generally related to the discharge of effluents from domestic, industrial and hospital sewage treatment plants into water bodies. Tetrabromobisphenol A (TBBPA), for example, is a brominated flame retardant from the production of plastics, coatings, and electronic products which poses a potential risk to human health and to the environment by being an endocrine, immunotoxic and, neurotoxic disruptor. The biological degradation of aromatic pollutants has attracted the attention of the researchers; However, little is known about the synergism of the microbial communities that act in the process and in which metabolic stage they have influence. In addition, Advanced Oxidation Processes (AOPs) are considered clean technologies applied in the de-grading of complex organic compounds. These technologies not only chemically transform pollutants but also have advantages such as the complete mineralization of some compounds, their oxidation at very low concentrations, and the generation of non-polluting products. The combination of chemical and biological processes is specifically suited for the removal of compounds of difficult degradation present in a complex matrix, such as sewage. Thus, the objective of this work is to study the degradation of TBBPA by advanced biological and oxidative processes in order to propose a coupled treatment technology. (AU) | |
