“…In addition to PCDD/Fs and PBDD/Fs, mixed polybrominated/chlorinated dibenzo- p -dioxins/dibenzofurans (PXDD/Fs, X = Br and Cl) have been detected in indoor dusts, industrial water, waste materials, and fish. 14–17 In vitro studies have demonstrated that the molecular response profiles induced by PXDD/F exposure are comparable to those of TeCDD, TeBDD, and TeBDF, 18 suggesting that PXDD/Fs possess in vivo toxicities similar to those of PCDD/Fs and PBDD/Fs. Recently, we found developmental toxicities, such as higher mortality and cardiac abnormalities, in Japanese medaka ( Oryzias latipes ) embryos exposed to 2-chloro-3,7,8-tribromodibenzofuran (TeXDF) and 1,2,3,7,8-pentabromodibenzofuran (PeBDF) detected in industrial water and indoor dusts, respectively.…”

Epidemiological and experimental studies indicate that maternal exposure to environmental pollutants impairs the cognitive and motor functions of offspring in humans and laboratory animals. Infant ultrasonic vocalizations (USVs), the communicative behavior of pups toward caregivers, are impaired in rodent models of neurodevelopmental disorders, suggesting a useful method to evaluate the developmental neurotoxicity of environmental pollutants. Therefore, we investigated USVs emitted by mouse pups of dams exposed to 2-chloro-3,7,8-tribromodibenzofuran (TeXDF) and 1,2,3,7,8-pentabromodibenzofuran (PeBDF), which are detected in the actual environment. The USV duration and number in the pups born to dams administered with TeXDF 40 μg/kg body weight (b.w.), but not 8 μg/kg b.w., on gestational day (GD) 12.5, were significantly lower than those in the corresponding pups on postnatal days 3–9. Conversely, there was no statistical change in the USVs emitted by the pups of dams administered with PeBDF 35 or 175 μg/kg b.w. on GD 12.5. To examine whether maternal exposure leads to behavioral impairments in adulthood, we analyzed exploratory behaviors in a novel environment using IntelliCage, a fully automated testing apparatus for group-housed mice. Neither TeXDF nor PeBDF exposure induced significant differences in offspring exploration. Considered together, our findings revealed that TeXDF induces atypical USV emission in infant mice, suggesting the importance of further studies on the risk assessment of mixed brominated/chlorinated dibenzo-p-dioxins and dibenzofurans.

“…Different from PCDD/Fs, the acknowledgments of PBDD/Fs and PBCDD/Fs were dominantly based on the limited field studies investigating their congener patterns. ,, Equivalents of the accepted PCDD/Fs formation mechanisms cannot fully explain PBDD/Fs and PBCDD/Fs emission characteristics during the combustion processes. Reactions involving both bromine and chlorine atoms to form PBDD/Fs and PBCDD/Fs are much more complicated than reactions involving only chlorine atoms to form PCDD/Fs.…”

Understanding the mechanisms through which persistent organic pollutants (POPs) form during combustion processes is critical for controlling emissions of POPs, but the mechanisms through which most POPs form are poorly understood. Polyhalogenated dibenzo-p-dioxins and dibenzofurans (PXDD/Fs) are typical toxic POPs, and the formation mechanisms of PXDD/Fs are better understood than the mechanisms through which other POPs form. In this study, a framework for identifying detailed PXDD/Fs formation mechanisms was developed and reviewed. The latest laboratory studies in which organic free radical intermediates of PXDD/Fs have been detected in situ and isotope labeling methods have been used to trace transformation pathways were reviewed. These studies provided direct evidence for PXDD/Fs formation pathways. Quantum chemical calculations were performed to determine the rationality of proposed PXDD/Fs formation pathways involving different elementary reactions. Many field studies have been performed, and the PXDD/Fs congener patterns found were compared with PXDD/Fs congener patterns obtained in laboratory simulation studies and theoretical studies to mutually verify the dominant PXDD/Fs formation mechanisms. The integrated method involving laboratory simulation studies, theoretical calculations, and field studies described and reviewed here can be used to clarify the mechanisms involved in PXDD/Fs formation. This review brings together information about PXDD/Fs formation mechanisms and provides a methodological framework for investigating PXDD/Fs and other POPs formation mechanisms during combustion processes, which will help in the development of strategies for controlling POPs emissions.

“…The most commonly encountered POPs in wastewater are synthetic dyes (Shukrullah et al, 2021), agricultural waste such as pesticides and herbicides (Panis et al, 2022), endocrine disruptive chemicals (EDCs) from pharmaceutical waste such as antibiotics, anti-inflammatory, phenols, etc. (Ojha et al, 2021), organochlorine such as polychlorinated biphenyls (PCB) (Yasir et al, 2021), polychlorinated dibenzo-p-dioxins (PCDD), and dibenzofurans (PCDF) (Hashimoto et al, 2021). Advanced membrane separation is a promising and futuristic method for removing these POPs from wastewater due to their flexibility, wide range separation, and adjustable features (Kusworo et al, 2022).…”

Membrane technology has gained attention in wastewater treatment due to its great potential for producing high-grade water products for reuse. The membrane also effectively removes persistent pollutants in water effluent. However, their application is constrained by low productivity due to fouling formation. Incorporating functionalized nanoparticles into polymeric membranes has attracted much attention due to the improved membrane performance and additional features. Metal-organic frameworks (MOFs) incorporated into polymeric membranes have been widely applied in reverse osmosis (RO), forward osmosis (FO), nanofiltration (NF), and microfiltration (MF) for water and wastewater treatment. This short review presented recent findings, fabrication methods, and a systematic understanding of transport mechanisms under various operating conditions. This study also focused on several important parameters, such as improving physicochemical properties, membrane features, and performance enhancement in wastewater treatment. The reported studies show that MOFs incorporated membranes have reached >95% organic pollutants and 100% suspended solids. The membrane durability was also enhanced up to 140%, and the flux recovery can be maintained at 98% after several cycles. Even some MOFs, such as ZIF-8 and UiO-66, exhibited excellent performance in harsh conditions (pH < 4). The prospects and challenges of MOFs-incorporated membranes in industrial applications were also provided in this study.
