Summary: Recent investigations have found that adding manganese (Mn) sand to constructed wetlands significantly improves the removal of organic micropollutants (MPs). In addition to direct oxidation and adsorption, Mn oxides play a crucial role in the biotransformation of MPs. Lab-scale constructed wetlands were constructed with or without the addition of natural Mn sand to understand the influence of Mn oxides on the biotransformation of selected MPs commonly found in wastewater. The results showed that the addition of Mn sand improved the removal of MPs and enhanced their biotransformation.

Summary: Constructed wetlands (CWLs) are widely used for water environment protection, and the animals in CWLs play a crucial role in improving treatment efficiency, maintenance, and management, as well as affecting the removal of pollutants. The characteristics of CWL animals can be used for biological monitoring, while also promoting the conservation of wetland biodiversity.

Summary: Constructed wetlands have been widely used for domestic wastewater treatment, but the complex biogeochemical processes occurring within them, particularly regarding plant-soil (and nitrogen) interactions, are not well understood. This study used nitrogen porewater measurements and chemical imaging to investigate the impact of plants on soil redox dynamics and nitrogen biogeochemical cycling in constructed wetlands. The findings revealed that plant roots transported oxygen to anoxic sediments through radial oxygen loss, and the extent of oxic and anoxic areas strongly correlated with the removal of ammonium and nitrogen oxides. Additionally, microscale spatio-temporal redox heterogeneity within the rhizosphere promoted nitrogen removal by stimulating the coupling between nitrification and denitrification. This study highlights the significant role of plants in controlling soil conditions and nitrogen cycling in constructed wetland systems.

Summary: This review analyzes the removal of micro-pollutants from effluent of conventional wastewater treatment plants (WWTP) by different types of constructed wetlands (CWs). It was found that CW systems with organic enhanced adsorption substrates achieve the highest micropollutant removal efficiency, but the longevity of the enhanced adsorption effect is still unknown.

Summary: The mixture of triphenylamine (TPA) and phenyl phenothiazine (PTH) fragments in extended polyimine structures showed varying photocatalytic activities in the degradation of different pollutants under visible light irradiation. Materials with PTH as the sole photoactive unit exhibited the most active photocatalytic performance for polybrominated diphenyl ether-1 and Sudan Red III degradation, while the covalent organic framework containing only TPA was the best photocatalyst for degrading Methylene Blue. These differences were attributed to the versatile abilities of PTH to trigger both photoredox and energy transfer processes, compared to TPA which primarily acts as an energy transfer catalyst.

Summary: A hybrid constructed wetland system combining horizontal and vertical flow was used to treat carbon-deficient synthetic dyeing wastewater. The results showed that the system could effectively remove azo dyes from low-carbon dyeing wastewater. In the horizontal wetland, organic waste products served as the carbon source for microbial dye degradation, resulting in 90% color removal. The vertical wetland removed dye degradation organics, ammonium-nitrogen, and organic-nitrogen.

Summary: The presence of pharmaceuticals in aquatic environments poses challenges to water quality worldwide, including harmful effects on both ecological and human health, development of antibiotic resistance, and disruption of endocrine function in aquatic organisms. This study successfully used time-of-flight secondary ion mass spectrometry imaging to investigate the distribution of pharmaceuticals and endogenous molecules in the complex biological matrix of biofilms used in wastewater treatment. The findings showed that certain pharmaceuticals were located in specific sites within the biofilm, with colocalization mainly with phosphocholine lipids. This approach provides a powerful strategy for visualizing the chemical composition of biofilms and elucidating the mechanisms behind the removal of pharmaceuticals and antimicrobials in biological wastewater treatment.

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.

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 article assesses the importance of recovering metals from wastewater treatment plants (WWTP) from strategic, financial, and mining perspectives. The study finds a strong recovery potential for magnesium in the entire WWTP and identifies sewage sludge as the most suitable matrix to recover chromium and copper. Further investigation is required for metals like palladium, platinum, and tungsten found in incinerated sewage sludge ash. Several metals in treated wastewaters, including calcium, potassium, sodium, silicon, nickel, and zinc, show either strong financial potential or are critically important. Transforming WWTP into urban mines is an incentivized move towards a circular economy.

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.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
