Summary: Chemical oxidation as a pretreatment for petroleum-contaminated soil, coupled with bioremediation, can have serious impacts on indigenous microorganisms and available nutrients. This study found that hydrogen peroxide treatments significantly promoted the removal of total petroleum hydrocarbons (TPH), especially in the initial days, and also affected the levels of dissolved nutrients. Both chemical oxidation and nutrients contribute to changes in microbial community structure and diversity. However, the long-term effects of H2O2 as a pretreatment had little impact on the soil indigenous microbial community structure and actually facilitated the continuous removal of TPH by indigenous microorganisms.

Summary: Coastal wetlands are crucial for maintaining biogeochemical cycles as they are the convergence of terrestrial and marine ecosystems with unique ecological compositions and functions. Microorganisms in sediment play a vital role in material cycling, but coastal wetlands are facing degradation due to human activities and climate change. Therefore, understanding the microbial community structure, function, and environmental potential in coastal wetland sediments is essential for wetland restoration and function enhancement.

Summary: Constructed wetlands in high-altitude environments rely on native flora and associated microbial communities for survival. Carex rostrata, Deschampsia caespitosa, and Rumex alpinus are identified as plant species hosting active bacteria in nitrogen cycles, with the latter showing the richest and most stable fungal and prokaryotic communities. These findings suggest that Rumex alpinus should be prioritized in high-altitude constructed wetlands for its low maintenance requirements and effective water treatment capabilities.

Summary: Wetland ecosystems have a significant impact on the global carbon budget, serving as both carbon sources and sinks. The invasion of Spartina alterniflora has altered the carbon cycles in coastal wetland ecosystems, hindering the formation and accumulation of soil Fe-OC pool and weakening the stabilization of soil organic carbon (SOC).

Summary: A microbial consortium of hydrocarbonoclastic bacteria isolated from oil-saturated desert soil was tested for its ability to remove oil in batch cultures and in oil-polluted soil samples. The results showed that the consortium did not consume more oil than the individual species, and the rate of oil removal in the bioaugmented soil samples was similar to that in the unbioaugmented ones. The study also found that certain bacterial species, such as Arthrobacter ginsengisoli, played an important role in oil removal.

Summary: Nitrogen addition leads to significant changes in the structure and diversity of mangrove soil bacterial communities, as well as impacting microbial biomass and activity. Changes in nitrogen levels may alter the activity of enzymes involved in carbon, nitrogen, and phosphorus cycling, and increase the microbial metabolic quotient. These findings suggest potential implications for microbial communities and carbon and nutrient cycling in mangrove environments.

Summary: This study investigates the effects of tire particles (TPs) and their leachable additives on the microbial community composition and function in coastal sediments. The results show that environmentally relevant concentrations of TPs can change the microbial community structure, decrease community diversity, and inhibit nutrient cycling processes in sediments. Furthermore, leachable additives not only directly influence community function but also indirectly affect community diversity and function by shifting the community structure.

Summary: This study found that long-term fertilization and dry hydrologic conditions affect bacterial diversity, decomposition rates, and increase the potential for soil C loss. Bacterial communities decomposed high C:N ratio litter more quickly in fertilized soils, especially under drier conditions, while decomposition rates of low C:N ratio litter were similar between fertilized and unfertilized soils.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: Air pollution is associated with a range of health issues and gestational exposure to environmental pollutants may be linked to neurodevelopmental disorders. This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

Summary: Heteroatom doping can reconfigure the electronic structure of heterogeneous catalysts, leading to the development of advanced oxidation water purification materials with superior performance and stability. In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.
