Summary: The temporal dynamics of antibiotic resistance genes (ARGs) were investigated in vegetable greenhouse soil after the application of cattle manure, swine manure, and poultry manure. The results showed that the abundance of ARGs increased after manure application, with different effects depending on the type of manure. The abundance of certain bacteria groups was positively correlated with specific ARGs, indicating their potential role as hosts. The study highlighted the importance of intI genes in the spread of ARGs and emphasized the need for proper measures to reduce the associated risks.

Summary: The addition of organic amendments, such as manure and straw, to arable fields as a substitute for mineral phosphorus (P) is a sustainable practice in agricultural production. This study examined the effects of different organic inputs on soil organic carbon (OC) stability, phoD bacterial communities, and P forms in soils. The results showed that organic amendments significantly increased soil labile P and enzyme-P contents, while decreasing soil C aromaticity and recalcitrance indexes. The keystone genera in manured soils and straw-applied soils were correlated with soil enzyme-P, microbial biomass P, and different P species. This study highlights the importance of organic amendments in promoting soil P availability and enhancing environmental sustainability.

Summary: This research investigated the occurrence of antibiotics in chicken manure and soil samples from different chicken farms in Hangzhou, China. The results showed that the concentration of fluoroquinolones was much higher than that of sulfonamides and tetracyclines. Moisture content, total organic carbon, and total nitrogen had a significant influence on antibiotic concentration in the soil samples. The risk assessment indicated that certain antibiotics posed a high or medium risk in the soil.

Summary: The study assessed the potential ecological risks of 15 pesticide residues detected in agricultural soils in the Gaidahawa Rural Municipality of Nepal using European Food Safety Authority methods. The results indicated high risks for soil organisms from chlorpyrifos, imidacloprid, and profenofos, with chlorpyrifos posing chronic toxicity to F. candida across all soil depths. The ecological risk assessment showed that EFSA soil organisms were at risk in some localities where farmers practiced conventional farming.

Summary: Previous research has shown that agricultural production systems can contribute to the spread of antibiotic resistance genes in the environment. This study analyzed different samples to compare the levels of antibiotic resistance genes in vegetables, soil, and amendments derived from beef or dairy cattle. The findings suggest that vegetables have the highest diversity of antibiotic resistance genes, and vegetables grown in soil amended with manure or compost from beef cattle have higher levels of clinically relevant antibiotic resistance genes. Furthermore, the study highlights the importance of post-harvest processes in minimizing potential consumer exposure.

Summary: This study investigated the pollution characteristics and non-dietary human cumulative risk of neonicotinoids in vegetable greenhouse soils in Shandong Province, China. The top three detected neonicotinoids were imidacloprid, clothianidin, and thiamethoxam, with high detection frequencies and concentrations. The health risk assessment showed that the exposure risk to children was higher than that to adults, but all neonicotinoids were within safe limits.

Summary: The overuse of fertilizers and irrigation, as well as continuous monocropping, is causing soil degradation and the spread of soil-borne diseases, which jeopardizes vegetable production in solar greenhouses. Anaerobic soil disinfestation (ASD) has been introduced as a countermeasure but may increase N leaching and greenhouse gas (GHG) emissions. This study evaluates the effects of different amounts of chicken manure combined with rice shells or maize straw on soil O2 availability, N leaching, and GHG emissions during and after the ASD period.

Summary: Carbon sequestration in soil has been extensively studied in agroecosystems through increasing organic carbon inputs and reducing soil organic carbon degradation processes. However, the influence of shallow water table on mineral soils, despite the importance of soil moisture in modifying the carbon cycle, is not well understood. This study examines the effects of shallow water table on carbon balance components in mineral soils and finds that a negative carbon balance was observed under all treatments. The study also highlights the interaction between shallow water table and organic carbon type, which is crucial for carbon balance in mineral soils.

Summary: A considerable number of egg and Chinese cabbage consumers in Dodoma city were unaware of the likelihood of antimicrobial residues in these foods. The majority of chicken farmers raised layers and used antimicrobial drugs, mainly tetracycline and its derivatives, for the treatment and prevention of diseases.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
