Summary: Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) have raised concerns due to their persistence, wide distribution, biotoxicity, and bioaccumulative properties. Phytoremediation offers a promising alternative to traditional cleanup methods for PFOA and PFOS. This review discusses the uptake, translocation, and toxic effects of PFOS and PFOA, as well as potential hyperaccumulators and indicators of biotoxicity for these chemicals.

Summary: The objective of this study was to determine the most representative methods of measuring air-water interfacial area for the retention and transport of PFAS and other interfacially active solutes in unsaturated porous media. Comparing multiple measurement and prediction methods, it was found that all methods produced coincident results for the interfacial area of glass beads, validating the aqueous interfacial tracer-test methods. The differences in interfacial areas measured for sands and soil were shown to be due to method-dependent contributions of solid-surface roughness.

Summary: In this study, the effects of environmentally-relevant levels of PFAS on caged canaries were analyzed using physiological, immunological, and transcriptomic analyses. Although no effects were observed on physiological and immunological parameters, the transcriptome of the pectoral fatty tissue showed changes compatible with the known effects of PFAS as obesogens in other vertebrates. These results indicate the potential hazard of PFAS on the fat metabolism and the immunological system of birds and highlight the ability of transcriptomic analyses to detect early physiological responses to toxicants. Tight control of the exposure of natural populations of birds to these substances is necessary due to the essential functions affected.

Summary: Cooking can reduce PFAS concentrations in animal-derived food products, but complete elimination of PFAS requires unrealistically long cooking times and large liquid/animal tissue ratios. Currently, there is a lack of literature on the impact of cooking terrestrial animal produce on PFAS concentrations.

Summary: This study investigates the biomagnification of Poly- and Perfluoroalkyl Substances (PFAS) in striped dolphins in the North-Western Mediterranean Sea and examines the temporal trends of PFAS concentrations over the past three decades. The results show that PFAS, especially the long-chain compounds, have bioaccumulated in dolphins and may have potential health effects. The findings contribute to the understanding of PFAS pollution in marine ecosystems and can support future ecological risk assessments and management strategies.

Summary: This study investigated the short- and long-term effects of two commonly detected compounds, perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), on the laboratory-reared mayfly Neocloeon triangulifer in water only exposures. The study found that mayflies were highly sensitive to PFOS and PFOA, with PFOS being more toxic than PFOA. The research highlights the risks of PFOS to freshwater insects and suggests the need for further investigation into the toxicity of different compounds on these organisms.

Summary: A new conductive Cu-Ni-based hybrid ink has been proposed, which can be sintered at 150-180 degrees C to produce Cu-Ni electrodes with low electrical resistance, high oxidation resistance, and flexibility. The Cu flakes and NiF-AmIP complex in the hybrid ink catalyze the self-reduction process, forming Cu-Ni electrodes with high conductivity at temperatures exceeding 150 degrees C. The Cu-Ni electrodes demonstrated high stability against oxidation and mechanical bending stress, showing great potential for printed/flexible devices.

Summary: In this study, the antibacterial activity of a hydrogel system composed of sodium alginate (SA) and basic chitosan (CS) was improved by adding AgNPs using sodium hydrogen carbonate. SA-coated AgNPs were produced via ascorbic acid or microwave heating, and their antimicrobial activity was evaluated. The microwave-assisted method was found to produce uniform and stable SA-AgNPs with an optimal reaction time of 8 minutes. The SA-AgNPs/CS gel formed successfully and demonstrated higher mechanical strength and low cytotoxicity, exhibiting inhibition zones against E. coli and B. subtilis.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
