Summary: The study shows that composted manure, in combination with reduced fertilizer rate, was always superior to stockpiled manures in horticulture, reducing greenhouse gas emissions by 9 to 90%. However, the higher costs associated with purchasing and transporting composted manure created a greater economic burden.

Summary: This study investigated the impacts of different alkaline biochars (from walnut shell, coconut shell, and coal) on gas emissions from liquid pig manure. The results showed that the application of biochars significantly increased NH3 and CH4 emissions, with the absorbed N content of the biochars lower than the enhanced gaseous losses through NH3 emissions. The total greenhouse gas emissions were also higher with biochar application, mainly due to enhanced CH4 emissions.

Summary: The development and utilization of after-treatment devices in modern vehicles have increased emissions of NH3 and/or N2O, leading to certain regions introducing limits on these emissions. However, the lack of on-board systems has prevented regulating real-world emissions. This study evaluated on-board systems for measuring NH3 and N2O emissions from heavy-duty vehicles, finding good correlation with laboratory-grade FTIR and N2O concentrations during on-road testing.

Summary: This study synthesizes data on nitrogen emissions in Canada's 10 provinces over three decades, finding variations in the contribution of different nitrogen species to total emissions and significant effects of economic structural changes. Reducing emission intensity and transitioning towards less nitrogen-intensive sectors are crucial for further reducing nitrogen pollution.

Summary: The research findings show that climate is the major driver of direct N2O emissions from managed soils, with emissions significantly higher in wet climates compared to dry climates. The form of fertilizer also plays a significant role in modulating emissions, with synthetic and mixed forms resulting in higher emissions compared to organic forms in wet climates. Other factors such as land cover, soil texture, carbon content, and pH are also important regulators of emissions. By adopting the 2019 IPCC EF1, countries can improve the accuracy of emissions inventories and better target areas for implementing mitigation strategies.

Summary: This study conducted experiments in four Georgia Piedmont pastures during the summers of 2021 and 2022 to investigate the impact of filth flies and epigeal arthropods on carbon and nitrogen emissions and soil nitrogen retention in lax rotational grazing systems with low fertilization. The results showed that more than 12 ovipositing filth flies per manure pat can lead to a reduction of 14.7 kg nitrogen per hectare in PMN, while an increase in the biodiversity and abundance of predators may help to increase PAN and PMN in grazing systems and decrease the number of emerging filth flies.

Summary: The study unveiled the mechanism of action of nitrification inhibitors with copper elements, demonstrating the effects of 3,4-dimethyl-1H-pyrazole dihydrogen phosphate and a new DMP-based nitrification inhibitor. Despite their differences, both compounds showed the same nitrification inhibition efficiency in soils with varying copper content, suggesting that DMP plays an active role in both cases.

Summary: This study investigated the association between ambient PM2.5, O3 pollution, and ovarian reserve in reproductive-aged Chinese women. The results showed that increased exposure to PM2.5 and O3 was associated with decreased AMH levels, indicating reduced ovarian reserve. Notably, the effects of O3 exposure on ovarian reserve were different from those of PM2.5 exposure.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

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: The synergistic effects of trace sulfadiazine and cast-iron corrosion scales on the formation of disinfection by-products in drinking water distribution systems were investigated. The presence of magnetite resulted in increased concentrations of DBPs due to the higher microbial activity and enhanced microbial extracellular electron transport pathway. The study highlights the importance of considering trace antibiotics pollution and corrosion scales in water sources for DBP control.

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.
