Summary: High concentrations of PFAS have been detected in agricultural soils in Southwest Germany, believed to be caused by discharges of contaminated paper sludge and compost. PFCAs have also been found in groundwater, drinking water, and plants in the area. New compounds have been identified through HRMS, with diPAPs and diSAmPAP being major contaminants.

Summary: This study examined the presence and levels of 21 PFAS in marine species collected from Bizerte lagoon, Northern Tunisia, revealing the occurrence of PFAS in seafood from North Africa at low levels. The profiles of PFAS varied significantly among different species, and current exposure to PFAS through seafood consumption does not pose a significant concern for local consumers.

Summary: This study explored the use of industrial byproducts as sorbents for soil contamination stabilization. It found that slag waste and iron-rich charred fossil coal were effective in reducing the leaching of lead and antimony from soil. Fe-char showed strong sorption for per- and polyfluorinated alkyl substances (PFASs) in low total organic carbon (TOC) soil. Overall, industrial byproducts can provide sustainable and cost-effective materials for soil remediation, but the selection of sorbent should be tailored to the specific soil and contamination type.

Summary: The aim of this study was to investigate the applicability of phytoscreening for per- and polyfluoroalkyl substances (PFAS) contaminations at a contaminated site in Germany. Three plant species were sampled to evaluate seasonal and annual variations in PFAS concentrations. The results showed that different species had different PFAS concentrations, with the highest concentrations observed in white willow, followed by black poplar and black alder. The phytoscreening technique successfully detected and delineated the impact of PFAS on groundwater.

Summary: The EPAs of Denmark, Sweden, Norway, Germany, and the Netherlands have proposed a ban on the use of toxic industrial chemicals PFAS due to their harmful effects on human health and biodiversity. Denmark, the first EU country to ban PFAS, plans to establish groundwater parks to protect drinking water. They also call on the EU to list more toxic substances on the Stockholm Convention.

Summary: The impact of experimental conditions on the leaching behavior of PFAS was studied in three different experiments: batch, saturated column, and variably saturated laboratory lysimeter experiments. The study found that the immobilization efficacy of PFAS is chain-length dependent, and the differences in experimental results may be attributed to varying saturation conditions.

Summary: This article reviews the influence of soil- and water-derived dissolved organic matter (DOM) on the environmental fate of polyfluoroalkyl substances (PFAS). DOM plays a bidirectional role in the adsorption, degradation, and plant uptake of PFAS, depending on its types and functional groups. It is important to enhance the positive role of DOM in reducing the environmental risks posed by PFAS.

Summary: Identifying the adverse impacts of pesticide exposure is crucial for protecting wildlife and human health. In rice ecosystems, amphibians like the wild cane toad can serve as valuable indicators due to their sensitivity to pesticides during critical life stages. Our experiments with wild cane toads revealed that exposure to the common herbicide butachlor can lead to developmental delays, thyroid gland abnormalities, and downregulation of important metabolic and immune-related transcripts. Additionally, we found evidence of acclimatization in cane toads exposed to butachlor, suggesting potential long-term impacts of pesticide exposure in rice fields.

Summary: The co-fermentation of waste activated sludge and chicken manure significantly enhances the degradation of glucocorticoids, increases sludge reduction, and improves volatile fatty acid production. Even with a high glucocorticoid content, there is no impact on sludge hydrolysis and acidification. Mixing waste activated sludge with animal manure can reduce the toxicity of glucocorticoids and promote waste reduction and volatile fatty acid production.

Summary: This comprehensive survey investigated the occurrence, bioaccumulation, and trophic magnification of parabens and their metabolite 4-HB in a marine food web. Results showed that parabens were the predominant pollutants in marine organisms, with significant bioaccumulation from sediments. The estimated trophic magnification factor indicated biomagnification for MeP and trophic dilution for 4-HB. Overall, the risks for humans consuming marine organisms were found to be low.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: This study implemented a microaerobic-aerobic configuration in a full-scale municipal wastewater treatment facility and investigated the effects on sludge characteristics, pollutant removal, microbial community, and granulation mechanisms. The results showed successful transition from flocculent-activated sludge to well-defined AGS after two months of operation. The primary pathways for pollutant removal were simultaneous nitrification, denitrification, and phosphorus removal. Moreover, the incorporation of internal separators induced shifts in the flow pattern, which promoted granulation.

Summary: Efficient anaerobic digestion relies on the cooperation of different microorganisms with different metabolic pathways. This study investigated the effects of different operational modes and the addition of powdered activated carbon (PAC) on ethanol metabolic pathways. The results showed that the SBR mode and the presence of CO2 facilitated ethanol metabolism towards propionate production, while the CFR mode with extended solids retention time enriched Geobacter. Adjusting operational modes and PAC addition can modulate anaerobic ethanol metabolism and enrich Geobacter.

Summary: This study analyzed the occurrence and distribution of antibiotic resistance genes (ARGs) in different environmental media of the Yangtze River using metagenomics. Core resistome dominated by multidrug resistance genes was found in all samples, while rare resistome dominated by various resistance genes was more prevalent in plasmids. Specific bacteria were identified as hosts for both core and rare resistomes, with high clinical concern ARGs found in the rare resistome. Particle-associated environment provided the most ideal conditions for resistome hosts. This study provided insights into the genetic locations of ARGs and the community assembly mechanisms of ARG hosts in freshwater environments.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
