Summary: Microplastics, both primary and secondary, are emerging contaminants with wide applications in various products. Despite their proliferation, the environmental and health effects of microplastics are not fully understood, and their impact on wastewater treatment plants remains an area in need of further exploration. Further research is needed to understand the sources, interactions, and impacts of microplastics on the environment and human health.

Summary: Reclaimed wastewater associated biofilms contain diverse antibiotic resistance genes and mobile genetic elements, with antibiotics partially degraded but still above minimum inhibitory concentrations. The bacterial community composition and diversity are the main factors influencing resistance selection and propagation in biofilms. Increase in certain genera known to harbor antibiotic resistance genes in reclaimed wastewater exposed to antibiotics suggests the importance of maintaining high diversity to limit resistance dissemination among planktonic bacteria.

Summary: This study found that reclaimed wastewater associated biofilms contain antibiotic resistance bacteria and genes, which may contribute to the dissemination of antibiotic resistance. While exposure to antibiotics may lead to an increase in resistance genes within biofilms, the composition and diversity of bacterial communities may play a more significant role in resistance selection and propagation.

Summary: A full-scale trial was conducted in summer 2019 to investigate the effects of discharging tertiary treated wastewater into the Llobregat River on drinking water quality. The study found that while the river contained low concentrations of NDMA, the NDMA precursors were already present at high levels. The concentration of NDMA in the drinking water was consistently low, but the formation potential varied.

Summary: Pharmaceutical residues pose environmental concerns and their removal by conventional treatment plants is generally ineffective and carbon intensive. To achieve zero pollution goals, new approaches and technologies are needed to improve wastewater treatment and reduce the carbon footprint. Emerging low-carbon technologies show promise in achieving high removal efficiencies of pharmaceuticals in wastewater.

Summary: The operation of SBRs for 36 days to simulate the impact of AR-AFFF on wastewater treatment showed small reductions in mixed liquor solids content and nitrification rates after two days of exposure to the foam. The addition of AR-AFFF led to an increase in 6:2 FTS concentrations and a proposed biotransformation pathway suggested the degradation of precursors to final short-chain perfluorocarboxylic acid products. Data extrapolation indicated that approximately 70% of AR-AFFF could be removed via effluent and solids wasting after 4 days at a full-scale treatment plant, providing insights for downstream processes.

Summary: This study investigated the impact of treated wastewater (TWW) irrigation on antibiotic resistance genes (ARGs) in subsoil pore-water, finding that TWW irrigation increases ARG prevalence. The hypothesis was validated through field and laboratory experiments, showing that TWW irrigation promoted the spread of ARGs in subsoil pore-water.

Summary: This study investigates the adsorption of carbamazepine and ibuprofen from water using a Zr-based metal-organic framework (MOF). The results show that UiO-67(Zr)-BA(10) exhibits a high adsorption capacity for carbamazepine and ibuprofen, with the adsorption capacity for carbamazepine being 4.5 times that of commercial activated carbon. The study suggests the importance of loading adequate defects and increasing porosity in developing efficient MOF-based adsorbents for the purification of pharmaceutical-contaminated water.

Summary: The study found that irrigation with treated wastewater increased antibiotic concentrations and ARGs relative abundance in soil, but the abundance of ARGs in soil was not related to irrigation water quality, but rather to soil type, especially clay content. There were also no clear associations between targeted antibiotics or heavy metals and ARGs abundance in water or soil samples.

Summary: A facile thermal decomposition method was used to synthesize mesoporous Cu-doped MgO nanoparticles, which showed high activity as photo-Fenton-like catalysts for degrading pharmaceutical contaminants in water. The catalysts efficiently oxidized salicylic acid and converted tetracycline to other intermediates with a large portion undergoing full mineralization. Experimental results demonstrated the effects of Cu loading, overall catalyst loading, and H2O2 concentration on the conversion and rate constants of salicylic acid and tetracycline.

Summary: Due to antibiotic resistance, it is important to understand the behavior of antibiotics in soil systems to assess potential risks to human and animal health. This study examined the sorption and desorption behaviors of four commonly found antibiotics in soils under typical conditions. The results showed variations in sorption capacity and mobility among different antibiotics.

Summary: The study found various antibiotics and corresponding resistance genes in treated effluent but not in freshwater. Regardless of water quality or crop type, the plastic-covered soil irrigated with effluent retained some antibiotics, although significant correlations between detected antibiotics and corresponding resistance genes were not observed. The findings disprove the hypothesis that treated effluent may carry antibiotics resistance genes to irrigated soil and crops.

Summary: The incidence of antibiotic resistance is increasing and has become a major health concern. This study developed methods for isolating and quantifying four important antibiotics in water and soil samples. The results showed that matrix characteristics, pH, and the pKa's and functional groups of the antibiotics need to be carefully considered during the extraction process.

Summary: The Western United States is facing a severe drought, putting pressure on water management systems. The reliance on surface water for agricultural production is at risk, necessitating new innovations and partnerships. A case study in Arizona shows that farmers are adjusting their irrigation infrastructure to cope with changing water availability, guided by social relationships and physical infrastructure. This research contributes to the understanding of adaptive environmental management and the hydrosocial cycle.

Summary: Pollution with emerging microscopic contaminants such as microplastics (MPs) and nanoplastics (NPs) including polystyrene (PS) in aquatic and terrestrial environments is increasingly recognized. PS is largely used in packaging materials and is dumped directly into the ecosystem. This systematic review focuses on PS contamination in agricultural soils, covering sources, effects, and mitigation methods, and provides updated information on the impacts of PS on soil organisms, plant uptake, and effects on higher animals and humans.

Summary: A tandem strategy was developed to recover NH4+ and PO43- nutrients in a solid form from simulated wastewater after Fenton oxidation of organic contaminants. Mesoporous Cu-MgO nanoparticles were used as a catalyst for the oxidation of paraoxon and tetracyline while mesoporous MgO nanoparticles were used as the Mg-source for struvite crystallization. Fenton oxidation was necessary to remove hazardous contaminants before struvite synthesis, and the resulting product was verified to be struvite free of organic contaminants through XRD and Raman spectroscopy.

Summary: In this study, the effect of air injection on corn and sugar beet yield was evaluated when using effluent from a feedlot lagoon as an irrigation water source in a subsurface drip irrigation system. The results showed that air injection treatment had a positive impact on corn yield, significantly increasing it in the 2021 growing season. However, no significant difference was observed in sugar beet yield between the air injection and non-injection treatments.

Summary: Biochars produced from cotton gin waste and guayule bagasse were characterized and explored as effective adsorbents for pharmaceutical removal from water. The adsorption mechanism involved hydrophobic partitioning, hydrogen bonding, and electron donor-acceptor interactions, with pH and specific surface area of biochar playing significant roles in adsorption efficiency. Adsorption of pharmaceutical compounds was found to be influenced by pH and contact time, indicating the potential of biochars for successful water treatment.

Zinc ions can be incorporated into the struvite lattice, while copper ions inhibit its formation. The resulting solid precipitates affect soil microbial biomass carbon and soil dehydrogenase enzyme activity.
