Summary: The possibilities of expanding a groundwater quality monitoring scheme using POCIS as the receiving phase were explored in Slovakia. The effectiveness of POCIS for sampling polar or ionized compounds was found to be limited. Sampling site and period, as well as physico-chemical parameters, can influence the sampling rates. Concentrations of pollutants in POCIS could be used for predicting average concentrations in water.

Summary: Chemcatcher (TM) (CC) and Polar Organic Chemical Integrative Samplers (POCIS) passive samplers were used to investigate trace organic chemical residues in urban streams of Sydney. The study detected a total of 254 chemicals, including aliphatic compounds, pesticides, phenols, PAHs, sterols, fatty acid methyl esters, pharmaceuticals, and personal care products. The sampling rates ranged from <0.001 to 0.576 L day(-1) depending on the type of sampler and chemical. The deployment duration analysis showed that some chemicals had higher detection rates after four weeks for CC SDB-RPS and three weeks for POCIS Oasis HLB. Rainfall was found to be positively correlated with higher detection rates in both estuarine and freshwater sites.

Summary: The contamination of aquatic ecosystems by hydrophobic organic contaminants (HOCs) is often evaluated based on their concentrations in riverbed sediment and suspended particulate matter (SPM). However, the total HOC concentration (C-TOT) in sediment or SPM has limited value in assessing the exposure of benthic or pelagic organisms. The accessible HOC concentration (C-AS) provides a useful parameter for quantifying the overall pool of HOC available for partitioning to the water phase or biota. This study compared C-TOT and C-AS in SPM and sediment samples collected from the Danube River and found that they provide complementary but not interchangeable information on HOC contamination.

Summary: In this study, it was demonstrated that sublethal-dose exposure to triclosan (TCS) and triclocarban (TCC) induced immunotoxicity in larval zebrafish. TCS exposure increased neutrophils and macrophages while decreasing thymic T cells, whereas TCC exposure significantly reduced all three types of cells, indicating suppression of thymus development and T-cell differentiation. Transcriptomic analysis revealed differentially expressed genes (DEGs) primarily involved in immune response, with TCC exposure showing more severe immunotoxicity than TCS. The differential target molecules and action pathways induced by TCS and TCC exposure provide potential diagnostic targets and toxicological endpoints.

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.
