Summary: The study demonstrates that struvite-loaded zeolite amendment can effectively alleviate the combined pollution of heavy metals, antibiotics, and antibiotic resistance genes in microplastic-contaminated soil. Through altering pollutant bioavailability, soil properties, and soil microbe communities, the zeolite indirectly reduces the proliferation of antibiotic resistance genes in the soil.

Summary: The formation of leachate is mainly due to the percolating of rainwater through the landfill and the processes taking place inside the landfill. This study aims to evaluate and compare the physicochemical characteristics of leachate, demonstrate the time variability of leachate parameters during landfill stabilization, present the relationships between leachate characteristics, and indicate the factors determining leachate composition variability. The Leachate Pollution Index (LPI) was used to assess leachate pollution and its potential. The results showed differences in leachate characteristics and pollution potential between the Lubna and Zdounky landfills.

Summary: In this study, the presence of PPE waste was surveyed in Bogota-Colombia, Lima-Peru, and Mar del Plata-Argentina. The release capacity of Ag, Cu, and Zn metals associated with nanoparticles and microplastics from TFMs and disposable face masks was also investigated. The findings suggest that PPE waste is more prevalent in low-income areas, possibly due to waste collection and economic activity patterns. TFMs were found to release high levels of Cu, Zn, and MPs, which can have potential toxic effects on aquatic organisms.

Summary: The moss-bag method is the most widely used technique for active biomonitoring of air pollution using mosses. This study evaluated the air pollution by selected heavy metals using three moss species during a 12-week exposure in an urban area. The results indicate that all moss species survived and retained their vitality, although it decreased during the exposure. P. schreberi moss showed the highest relative accumulation factor (RAF) increments and is recommended as the best biomonitor. The moss-bag technique has a significant effect on the concentration of a given metal for a certain species, making it the most recommended technique for air quality monitoring in urban areas.

Summary: The study aimed to evaluate the level of air contamination around a industrial enterprise in Tula, Russia during the winter of 2021/2022. Mosses including Pleurozium schreberi, Sphagnum fallax, and Dicranum polysetum were used for the first time in a 3-month active biomonitoring study. The results showed that wind direction influenced moss contamination at selected measurement points, and the accumulation of heavy metals elements indicated industrial pollution in the area.

Summary: Screening high Cd-accumulating plants and understanding the interactions between plants, rhizospheric microbes and Cd are important in developing microbe-assisted phytoremediation techniques for Cd-contaminated soils. In this study, the Cd tolerance and accumulation characteristics of three Phytolacca species were compared, and it was found that Phytolacca icosandra and P. polyandra had high Cd-accumulation capacities, making them potential candidates for phytoremediation. The study also revealed that the rhizospheric soil pH, available Cd concentration, and certain bacterial taxa were differentially altered in the presence of the Phytolacca plants, and these alterations influenced the Cd uptake by the plants.

Summary: The study revealed that the concentrations of heavy metals V, Cr, Co, Ni, Cu, Zn, Cd, and Pb in the surface sediments of Luoyuan Bay exceeded the marine sediment quality standards, indicating a potential ecological hazard. Higher concentrations of heavy metals were observed in the north and lower concentrations in the south, with V, Al, Co, Ni, and Pb originating from weathering and erosion of rocks and industrial wastewater discharge, while Cu, Zn, Cr, and Cd were primarily associated with ship transportation and repair, and marine aquaculture activities.

Summary: This study investigated the occurrence and characteristics of microplastics (MPs) in the surface water and sediment of the Buriganga river in Bangladesh. The results showed that MPs were widely distributed in the river, mainly in fragment form, with polypropylene (PP) being the most common polymer type. The MPs were contaminated by heavy metals and the pollution load index (PLI) indicated a higher risk level in downstream areas influenced by anthropogenic activities.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
