Summary: The study found that before the WWTP replacement, ER, GR, and PPAR gamma bioactivities were detected at the WWTP outflow but diminished downstream. In March 2018, the WWTP effluent was acutely toxic to the fish due to elevated ammonia concentrations. Following the WWTP replacement, bioactivities were significantly reduced, no toxicity was observed in caged fish, and concentrations of many bioactive chemicals decreased.

Summary: A GC-MS analytical method was established and validated for simultaneous determination of ten BPs and twelve NEs in drinking water. Eighteen out of twenty-two targeted compounds were detected in drinking source waters of eight DWTPs. Although the conventional treatment process could efficiently remove BPs and NEs, some compounds were still found in the finished drinking waters, posing a potential risk to human health.

Summary: In this study, the water footprint of a wastewater treatment plant (WWTP) was assessed before and after the addition of a water reclamation unit. The impacts of water reclamation on blue and grey water footprints were investigated. The results showed that the water footprint increased slightly after the addition of the water reclamation unit. Energy consumption and sludge treatment were identified as major contributors to the blue water footprint, while total nitrogen and total phosphorus were the most limiting pollutants for the grey water footprint. The environmental benefit of water reclamation in reducing the grey water footprint was determined to be 44%.

Summary: In recent years, beta-cyclodextrin (beta-CD)-based polymers and nanosystems have been extensively studied for water purification due to their high efficiency in removing inorganic, organic, and heavy metal impurities. The hydrophobic cavities and hydrophilic functional groups of beta-CDs form inclusion complexes through host-guest interactions, making them effective adsorption materials with modification capabilities. The article discusses various beta-cyclodextrin derivatives and their nanoparticulate systems, highlighting the chemical reactions for synthesis and mechanism of adsorption.

Summary: Continuous consumption and incomplete removal during wastewater treatment lead to constant introduction of psychoactive substances into the aquatic environment, potentially affecting non-target organisms. This study determined drug residues of psychoactive substances in wastewater and receiving rivers of six Slovene municipal wastewater treatment plants. The removal efficiencies varied among different treatment technologies, with higher removal rates for some substances. Although there were seasonal variations, no general pattern could be observed. The environmental risk assessment revealed that certain substances pose a risk to aquatic organisms, supporting the need for regular monitoring and regulatory actions.

Summary: This study investigated the degradation of micropollutants in wastewater through ozonation, identifying different removal pathways and rates for various types of organic micropollutants. The research found that low and medium oxidizable micropollutants were mainly removed through indirect pathways, while high oxidizable micropollutants were eliminated through direct pathways. The model developed in the study successfully simulated the removal efficiencies of specific micropollutants in batch experiments and in a full-scale ozonation process.

Summary: The accumulation of Hg in the Balearic Abyssal Plain was investigated through a comprehensive study of sediment trap material and sediment cores, revealing that Hg is primarily mobilized in the twilight zone and that its downward flux depends on surface water productivity. Results indicate that Hg is weakly coupled to the iron cycle but strongly associated with sulfur, supporting the assumption that its vertical distribution was minimally affected by diagenetic processes.

Summary: This study investigated the use of the non-reactive fraction of metals in fingerprinting to estimate historical contributions of suspended particulate matter (SPM) in sediment cores. Results showed that the nonreactive fraction retained more metals in deeper layers, and tributary contributions computed using this fraction were more consistent with historical data and had lower uncertainties. This approach enables robust identification of sub-catchment areas providing large quantities of SPM.

Summary: The study found that G. fossarum efficiently takes up Cd and eliminates it more rapidly compared to the mussel M. galloprovincialis. The organs that accumulate and depurate the most concentrations of both metals are the caeca and intestine. The one-compartment TK model is most relevant for Hg, while the multi-compartments TK model fits Cd data better, demonstrating dynamic transfer of Cd among organs.

Summary: The diffusive gradient in thin film technique was applied to measure organic compounds in this study. Two methods for measuring the diffusional coefficient (D) were compared for 112 organic compounds. The D-stack method tends to be higher than the D-cell method, and is considered as a reference value for diffusion in gel.

Summary: This study demonstrates the advantages and limitations of using passive samplers for monitoring polar contaminants in surface waters. The results show that POCIS has a higher quantification frequency for most contaminants compared to spot samples, and it lowers the limits of quantification. POCIS is able to capture short-duration and high-intensity contamination events, and it provides more reliable annual monitoring and assessment of environmental quality compared to spot sampling.

Summary: This study examined the effect of karst on antibiotic-resistant bacteria, specifically extended-spectrum beta-lactamases-producing Escherichia coli (ESBL-Ec), in a rural karst hydrosystem providing drinking water. The concentrations of ESBL-Ec were found to be spatially and temporally heterogeneous, with no filtration effect observed in the karst. The results suggest that karst poses a risk for the transmission of antibiotic-resistant bacteria.
