Summary: This study presents a non-invasive approach using Electrical Resistivity Tomography (ERT) to identify the state of underlying subsoil in a closed urban waste landfill. The results showed the absence of large karstic cavities and indicated the presence of electrically conductive anomaly potentially linked to leachate release. The approach proved to be a valuable tool for characterizing and monitoring closed landfills.

Summary: The study aimed to design, construct, and monitor a fully instrumented pilot-scale PMOB to reduce fugitive methane emissions from a closed landfill in Kitchener, Ontario, now a public park. Factors considered in the design include type of PMOB media, methane loading rates, hydraulic behavior, and ambient temperature. Methane oxidation efficiencies between 73% and 100% were achieved during the monitoring period. Successful mitigation will provide a low-maintenance, high-impact technology that could be adopted by the municipality for abatement of methane emissions at other landfills under its management.

Summary: The marine environment is constantly being polluted by tens of thousands of anthropogenic chemicals and wastes, leading to a need for a deeper understanding of the effects on natural ecosystems. Current research often focuses on short-term responses to stressors, lacking an evolutionary perspective through multigenerational studies. Addressing whether marine organisms can acclimate or adapt to a rapidly changing chemical environment is crucial for accurately predicting the risks of pollution in the ocean.

Summary: The aim of this study was to assess the microbiological and chemical air quality in a municipal solid waste landfill and its surroundings. The results showed that only CO, CH4, H2S, and NH3 were detected inside the landfill, while the microbiological contamination level did not differ significantly between the landfill and its surroundings. Furthermore, the number of microorganisms in the air varied depending on the season, with lower counts during winter, spring, and early summer compared to late summer and autumn.

Summary: This study investigated the photocatalytic degradation of conventional and emerging pollutants using core-shell zinc doped hexacyanoferrate@Prussian blue nanoparticles under light irradiation. Different synthesis parameters were studied, and the optimized photocatalyst degraded 94% of methylene blue within 24 minutes. The nanoparticles also showed potential for the photodegradation of parabens in municipal wastewater. The results suggest that these nanoparticles can be used for effective photocatalytic remediation of various pollutants.

Summary: Maternal transfer is a major exposure route for contaminants in birds, with PFAS compounds like linPFOS dominating in females and eggs. The study also found fluorotelomer carboxylic acid and ADONA in egg yolks for the first time, with emerging compounds below detection limit in female plasma. The transfer of PFAS to eggs was linearly related to the females, and PFCAs with longer carbon chains were preferentially transferred. The second-laid eggs had 73% of the PFAS levels compared to the first-laid eggs. Further research on the impact of maternal transfers on avian development physiology is warranted, especially for under-represented PFCAs and emerging fluorinated compounds.

Summary: A quarter of the world's population uses groundwater from karst aquifers, which are the most vulnerable groundwater systems to anthropogenic pollution. Studies have shown that the majority of compounds detected in karst groundwater are pharmaceuticals and pesticides, with concentrations varying over five orders of magnitude, and over half of the detected compounds exceeding 100 ng/L.

Summary: The management and mitigation of emerging contaminants and pollutants in the environment through bioresources is a growing focus of research. Various strategies can be combined with existing remediation technologies to effectively eliminate emerging contaminants from the environment. Among these strategies, the use of microbial bio-machines is prioritized due to its renewable and eco-friendly approach. This review examines the impacts of emerging contaminants on humans and ecosystems, the use of microbial bio-machines for handling these contaminants in water environments, and the challenges and advantages of this approach.

Summary: The study revealed that process wastewaters from food, beverage, and feedstock facilities contain a wide range of chemical and microbial contaminants, with bacteria resistant to antibiotics often detected. Despite disinfection treatment prior to discharge in 48% of cases, the discharge of these wastewaters may pose potential biological effects and toxicity to vertebrates and invertebrates.

Summary: Iron mineral transformations are linked to the biodegradation of hydrocarbons, and magnetic susceptibility measurements are useful for monitoring the natural attenuation of hydrocarbons. However, certain magnetic susceptibility perturbations remain poorly understood, and the characteristics of iron mineral phases associated with these perturbations are largely unknown, requiring further research.

Summary: This study provides a comprehensive investigation into the groundwater chemistry of residual hydrocarbon source zones in different stages of aging. The results show a direct relationship between benzene and naphthalene concentrations in residual oil and water samples collected below the oil. The chemical composition of groundwater associated with oil near the spill site differs from that associated with oil spread downgradient, indicating a shift in biodegradation reactions. These findings highlight the spatial and temporal heterogeneity of source zone processes.

Summary: A pipeline spill of unconventional oil and gas wastewater in North Dakota resulted in the contamination of Blacktail Creek. This study conducted a multi-level investigation to assess the potential effects of the spill on aquatic life, using fish bioassays, microbial community analysis, and estrogenicity measurements. The results showed early biological effects of the spill, including changes in microbial community structure and estrogenicity. The sediment acted as a sink for spilled constituents and indicated continued and cumulative effects post-spill.

Summary: The study compares the contributions of different reuse waters (wastewater effluent, urban stormwater, and agricultural runoff) to surface water contamination, revealing substantial organic-chemical contributions from each source. Episodic storm-event organic concentrations and loads from urban stormwater are comparable to and sometimes exceed those of daily wastewater effluent discharges. The study also assesses the impact of wastewater-effluent irrigation on organic-chemical concentrations in rain-induced agricultural runoff and harvested feedstock, finding minimal differences except for two specific organic substances in effluent-irrigated corn.

Summary: We evaluated the distribution of 35 elements in aquifer sediments and groundwater contaminated with crude oil, and found that barium, strontium, cobalt, and nickel were dissolved during hydrocarbon oxidation coupled to Fe(III)-reduction by microorganisms. These dissolved trace elements formed plumes in the contaminated aquifer, with mobilization rates exceeding the pre-contamination estimates. Concentrations of Ba2+ and Ni2+ in the groundwater exceeded the drinking-water guidelines. However, sediments acted as a barrier and attenuated the plumes, resulting in minimal dissolved trace element masses in the groundwater.

Summary: A comprehensive study of stormwater runoff events at 21 sites across the United States measured 438 organic and 62 inorganic chemicals, revealing localized contamination with potential adverse effects on aquatic health. By assessing cumulative ratios of exposure-activity cutoffs and cumulative toxicity quotients, the study found moderate to high risks for acute adverse effects on aquatic organisms across multiple trophic levels near stormwater discharge points. However, these results are likely significant underestimations of actual risk due to the limited number of compounds analyzed compared to those in commercial use and potential metabolites.
