“…20 In a similar vein, there are two articles from 2016 that discuss various methods of purifying bisphenols and other EDCs from the water supply using various methods. 21,22 Finally, there were two articles that concerned the health effects of bisphenol on aquatic sea-life. The first was a study of the effects of BPA on the water louse 23 and the second was a study of the effects of BPA, BPF and BPAF on various marine organisms.…”

Bisphenol compounds are a class of chemical epoxy resins that are found throughout the world in food packaging, thermal paper products, dental materials, and more. These compounds were deemed to be safe until recently, when some studies noticed adverse effects at very low doses, due to the fact that bisphenol acts as an endocrine disruptor. Over the last ten years, studies have been performed to detect bisphenols (especially BPA) in serum and blood samples throughout the world. Essentially, the majority of the earth's population seems to have significantly measurable levels of bisphenol in their blood plasma or urine. However, the majority of the population is unaware that a potential danger may exist. The purpose of this mini-review is to report upon the state of bisphenol research in the lesser developed member-states of the European Union and to increase awareness of the exposure level and possible adverse health effects of this endocrine disruptor. The results show that only three of the most newly admitted members of the European Union have published research concerning the health effects and/or environmental exposure of EU citizens to bisphenol compounds. Those countries were Slovenia, Poland and the Czech Republic. The rest of the surveyed member-states had little or no published research in relation to bisphenol compounds. Furthermore, even the three nations referred to above still lagged far behind the more advanced EU member-states. The lack of research could translate into a lack of awareness amongst the citizenry of nearly half of the EU, and may be unnecessarily putting those EU citizens at an increased risk of exposure.

“…Bisphenol-A is known to be one of the notable EDC (Endocrine Distrupting Compunds) and harmful to human health, agriculture and environment. BPA has stable structure so, degradation of Bisphenol A is difficult [5][6][7]. Compounds such as BPA at low concentrations have been found to be highly toxic, poorly biodegradable and present carcinogenic properties.…”

“…Development of environmentally friendly methods for removal of BPA is one of the most relevant issues in the field of reaching the clean water. Therefore, various methods like chemical oxidation [7,8,9], physical elimination development [10], biodegradation [11], adsorption [12] and photodegradation have been developed for the degradation of BPA [13].…”

The BPA into wastewater has posed a threat to environment and human health. Hence, we aimed to eliminate BPA in a short time and with a rapid degradation rate from food wastewater. Herein, the effects of different alkaline-earth oxide doped with Bi 2 O 3 nanoparticles on the photocatalytic degradation of bisphenol A were investigated. SrO-2 O 3 , CaO-Bi 2 O 3 and MgO-Bi 2 O 3 binary oxides were prepared by wet-impregnation method. The structural and optical features of catalysts were clarified BET, XRD, DRS, FT-IR, PL and SEM techniques. The photocatalytic activities of catalyts were compared for different light sources. Considering that the characterization analysis and experimental results, the highly improved photocatalytic activity was mainly attributed to the effective structure of the SrO-Bi 2 O 3 binary oxide and the strong alkali properties in the nanocomposite. Obviously, 5wt% SrO-Bi 2 O 3 photocatalyst showed more excellent degradation performance and highest degradation reaction rate (0.21 mg l -1 min -1 ) within 30 min. It was observed that the photocatalytic activity improved by the additive of alkaline oxide on Bi 2 O 3 .

“…Activated alumina, with acid-base active sites on their surface, high mechanical strength and good thermal stability, can be used as a suitable support [18]. Cotman et al [19] prepared ruthenium metal supported on alumina catalyst (Ru-Al 2 O 3 ) to catalyze ozonation of bisphenol A, and the catalyst Ru-Al 2 O 3 showed excellent stability and reusability. Wang et al [20] studied the manganese metal loading of 4% on Al 2 O 3 (Mn-Al 2 O 3 ) exhibited highest catalytic activity.…”

Excessive ammonia is a common pollutant in the wastewater, which can cause eutrophication, poison aquatic life, reduce water quality and even threaten human health. Ammonia in aqueous solution was converted using various systems, i.e., ozonation (O3), ultrasound (US), catalyst (SrO-Al2O3), ultrasonic ozonation (US/O3), ultrasound-enhanced SrO-Al2O3 (SrO-Al2O3/US), SrO-Al2O3 ozonation (SrO-Al2O3/O3) and ultrasound-enhanced SrO-Al2O3 ozonation (SrO-Al2O3/US/O3) under the same experimental conditions. The results indicated that the combined SrO-Al2O3/US/O3 process achieved the highest NH4+ conversion rate due to the synergistic effect between US, SrO-Al2O3 and O3. Additionally, the effect of different operational parameters on ammonia oxidation in SrO-Al2O3/O3 and SrO-Al2O3/US/O3 systems was evaluated. It was found that the ammonia conversion increased with the increase of pH value in both systems. The NH3(aq) is oxidized by both O3 and ·OH at high pH, whereas the NH4+ oxidation is only carried out through ·OH at low pH. Compared with the SrO-Al2O3/O3 system, the ammonia conversion was significantly increased, the reaction time was shortened, and the consumption of catalyst dosage and ozone were reduced in the SrO-Al2O3/US/O3 system. Moreover, reasonable control of ultrasonic power and duty cycle can further improve the ammonia conversion rate. Under the optimal conditions, the ammonia conversion and gaseous nitrogen yield reached 83.2% and 51.8%, respectively. The presence of tert-butanol, CO32−, HCO3−, and SO42− inhibited the ammonia oxidation in the SrO-Al2O3/US/O3 system. During ammonia conversion, SrO-Al2O3 catalyst not only has a certain adsorption effect on NH4+ but accelerates the O3 decomposition to ·OH.
