Summary: A global meta-analysis was conducted to investigate the effects of biochar on soil microbial communities, showing that biochar addition can increase arbuscular mycorrhizal fungal abundance and microbial biomass C, while decreasing soil respiration and actinomycetes abundance. The study also revealed that fungal abundance is the dominant factor affecting the response of bacterial abundance to biochar addition.

Summary: Rhizosphere microbial communities are influenced by soil type and cultivar, leading to changes in community composition, metabolic potential, and enzyme activities. Rhizosphere soils exhibit higher microbial activity and metabolic diversity compared to bulk soils. Soil nutrient studies reveal that both soil type and cultivar impact the availability of N, P, K, and organic carbon content in rhizosphere soil. These results highlight the importance of soil type and cultivar in shaping the microbial community abundance and metabolic potential in chickpea rhizosphere.

Summary: The effects of Cu on soil microbes depend on different Cu sources, with pure Cu salts being effective in estimating the impact on microbial biomass but not recommended for analyzing microbial community structure. Cu salt additions can lead to overestimations of Cu effects, especially at high concentrations, highlighting the importance of considering both Cu source and concentration in toxicity assessments.

Summary: Constructed wetlands are widely used as low-cost wastewater treatment systems and provide various ecosystem services. Microorganisms in wetland soils play a fundamental role in supporting wetland functions. This study found that both bacterial and fungal abundances increased with wetland age, with bacteria dominating the soil microbial communities in all ages of constructed wetlands. The stress indices showed that microbial stress may be influenced by changes in the availability of in situ nutrients in the wetland soils.

Summary: Despite the benefits of plastics in daily life, the accumulation of plastics in the environment, especially microplastics, can cause problems and potential loss of ecosystem services. This study investigated the effects of different types of microplastics on plant growth, soil enzyme activities, and microbial communities. The results showed that microplastics had a positive impact on plant growth but suppressed soil enzyme activities, except for urease activity. Microplastics also altered the structure and metabolic status of the microbial community. It was concluded that microplastics in soil are not benign and measures should be taken to restrict their access to the soil-plant system and food chain.

Summary: Alder and Pacific salmon play a crucial role in providing nutrients to freshwater systems in southwestern Alaska. While increasing alder cover leads to more alder-derived nutrients (ADNs), climate change and habitat degradation are reducing marine-derived nutrients (MDNs) in salmon-spawning habitats. This study investigates the influence of ADN and MDN on microbial community structure and function in lakes. The findings suggest that the influx and microbial use of MDN have significant effects on microbial metabolism, with higher metabolic activity occurring during salmon runs. The study also highlights the role of physical factors in mediating the effects of nutrient subsidies on microbial activity.

Summary: The conversion of a chestnut forest into an agricultural system for bean cropping in a national park in South Italy did not significantly change substrate utilization patterns in the soil, but rather resulted in a general decrease in soil activity due to reduced organic matter content. Seasonal effects on substrate utilization profiles and functional diversity indexes were observed, with two complementary approaches showing differences in discriminating between systems and highlighting variability among samplings.

Summary: Spatial and temporal variability are key attributes of sedimentary microbial communities, with larger distances having more dominant spatial effects on beta-diversity. Microeukaryotic photoautotrophs play a key role in structuring bacterial communities on streambed sediments. The study confirmed distinct microbial biogeography for headwater stream communities and highlighted the influence of environmental heterogeneity and geographical distance on microbial composition and spatial distribution.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
