“…Previous results have proved that the combination of different oxidation processes can increase the overall degradation of several pollutants (Agustina et al 2005;Augugliaro et al 2006). However, very few papers are devoted to the application of combined AOPs to endocrine disruptors removal (Guo and Feng 2009;Rivas et al 2009;Torres-Palma et al 2010).…”

Bisphenol A is an endocrine disruptor. Complete mineralization of bisphenol A is therefore a primary environmental issue. Here, the combination of ozonation and photocatalysis by TiO 2 is proposed for the degradation and final mineralization of bisphenol A. TiO 2 films deposited onto two sides of an Al lamina show good stability and high surface roughness. We used a specific experimental setup employing two facing ultraviolet lamps and TiO 2 layers, together with an ozone flux. High-performance liquid chromatography-mass spectrometry determinations on bisphenol A solutions sampled at different reaction times and Fourier Transform Infrared analyses of the oxide at the end of the reaction were performed to study the reaction intermediates and the overall degradation mechanism. Our results show that pollutant mineralization achieved with the combined method is far higher, of 55% in the case of 0.3 mM bisphenol A, than those obtained by individual treatments such as photolysis (\3%), ozonation (6%), photocatalysis (6%), and by other combined processes: photolytic ozonation (13%) and catalytic ozonation (15%). This finding is explained by the occurrence of highly synergistic effects.

“…Bisphenol A had been detected in all kinds of environmental water, the primary sources of Bisphenol A released to environmental water are expected to be the discharge of municipal effluent and industrial wastewater, also can be encountered in raw water [83,84]. The maximum concentrations reached up to 17.2 mg/L in hazardous waste landfill leachates [85], 12µg/L in stream water [86] and 0.1µg/L in drinking water.…”

Growing populations and increasing industry and agriculture activates have increased the existence of chemicals in the aquatic environment. The variety of anthropogenic chemicals that have been identified as potential endocrine disruptors (EDCs) in the environment and the problems arising from their use as human and livestock pharmaceuticals are discussed. Sewage effluents have been identified as a source of a diverse mixture of EDCs to the aquatic environment. These waters from homes and industries include natural and synthetic hormones (estrogens, androgens), active ingredients in pharmaceuticals, metals, pesticides, personal care product additives, and industrial chemicals. Once effluents are discharged to aquatic environments, EDCs will be diluted in stream or river waters so that organisms living very close to the discharge will have the highest exposure. Aquatic organisms also readily take up and store EDCs and its metabolites. Exposure to endocrine active compounds remains poorly characterized in developing countries despite the fact that behavioral practices related to westernization have the potential to influence exposure. Thus, in Egypt for example, it is likely that women in urban areas have a higher exposure to environmental hormonal risk factors, possibly xenoestrogens (EDCs) with regards to known risk factors of uterine and breast cancer.
