Summary: A sensitive and specific method has been developed for determination of PCB sulfates in human serum, with identification of multiple PCB sulfate congeners in a pooled sample, three of which exhibited the highest concentrations. The method involves extraction, analysis, and quantitation of PCB sulfates from serum, demonstrating its efficacy and potential for further toxicological studies.

Summary: Photocatalytic membranes (PM) have potential for water pollutant removal, but limited photo stability of polymeric PM systems poses a challenge. A proposed method combining common tools and accelerated ageing was used to evaluate PM stability. Three PMs based on different support membranes (PES, PVDF) and photo catalysts (TiO2, Pd porphyrin) were tested under intense UV-violet illumination for 250 hours.

Summary: The study focused on developing a computational model for evaluating the plasma gasification process of polychlorinated biphenyl wastes based on Gibbs free energy minimization. The results were satisfactory and validated by literature data. Various parameters such as temperature, equivalence ratio, steam-to-waste ratio, and carbon dioxide-to-waste ratio were found to significantly affect the production of syngas components.

Summary: This paper reports on a new fluorinated aromatic polymer, poly(biphenyl-trifluoroacetone) (PBT), for preparing high-performance hollow fiber ultrafiltration membranes. The PBT membranes exhibited excellent structure-performance relationship, with good scalability, membrane forming ability, separation performance, mechanical properties, and long-term stability.

Summary: The PVDF-P(L-DOPA)-ZnO hybrid membrane effectively removed cationic dyes and antibiotics from water through structural modifications and improved photocatalytic properties. The efficient separation of photoinduced electron-hole pairs promoted photocatalytic activity, leading to high stability even after 3 cycles of use.

Summary: Catalytic membrane reactors based on the sulfate-based advanced oxidation processes have great potential in water treatment. In this study, Cu-MOF-74 was synthesized and used as a surface modification layer for PVDF membranes. The modified membranes showed improved anti-fouling ability and catalytic activity, achieving high degradation efficiency of dye.

Summary: Assessing the health outcomes associated with exposure to PCBs is crucial due to their persistent and widespread presence. This study used systematic review methods to summarize and evaluate the noncancer health effects of PCB exposure. A comprehensive literature search identified 62,599 records, of which 1,586 studies met the criteria for analysis. The evidence map generated from this research provides valuable information for future systematic reviews and hazard assessments of PCB mixtures.

Summary: Functionalizing the interfaces of multication and halide perovskite solar cells with an organometallic compound, ferrocenyl-bis-thiophene-2-carboxylate (FcTc(2)), enhances their efficiency and stability. The resulting devices exhibit high performance and stability, as demonstrated by tests and continuous operation.

Summary: This study investigated the microbial diversity from the three domains of life in a long-term contaminated brownfield. The results showed a significant increase in microbial abundance according to PCB concentrations in soil samples. Some bacteria belonging to the Gammaproteobacteria class and fungi affiliated with the Saccharomycetes class or Pleurotaceae family, known for their ability to transform PCBs, were abundantly found in highly polluted soil samples.

Summary: The study quantified selected PCB congeners in Chabahr bay and surrounding areas in Iran, with concentrations varying from below detection limit to 485 ng kg-1 dry weight of sediment. The dominance of PCB 28 and 52 suggests maritime transportation and atmospheric deposition as important sources, with commercial products like ClophenA50 also potentially contributing. Overall, the impact of detected PCBs on aquatic organisms was deemed negligible based on guidelines.
