Summary: The distribution of antibiotic resistance genes (ARGs) in brackish water aquaculture sediment is similar to that in freshwater aquaculture, with the sulfonamide resistance gene sul1 as the indicator. The dominant phyla are Proteobacteria and Firmicutes, with Paenisporosarcina as the dominant genus. The microbial community in brackish water aquaculture sediment is function-driven and influenced by environmental factors and aquaculture activities. Overall, brackish water aquaculture serves as a reservoir for ARGs.

Summary: Wanfeng Lake in China has been heavily impacted by aquaculture and human activities, resulting in the accumulation of antibiotics and antibiotic resistance genes (ARGs). This study examined the presence of antibiotics, ARGs, mobile genetic elements, and microbial community structure in the lake. The results showed high concentrations of antibiotics in both surface water and sediments, with ofloxacin (OFX) and flumequine (FLU) being the most prevalent. The dominance of sulfonamide resistance genes in both water and sediments was observed. The study also identified the main microorganisms present in the sediment. Furthermore, a positive correlation was found between antibiotics, ARGs, and both environmental factors and microorganisms. These findings highlight the potential threats posed by antibiotics and ARGs in Wanfeng Lake, providing a basis for future research.

Summary: Polycyclic aromatic hydrocarbons (PAHs) are hazardous pollutants that are widely present in the environment and can accumulate in sediment, posing a threat to benthic communities in freshwater environments. This review provides an overview of the distribution of PAHs in freshwater environments and their toxicity to benthic fauna, and highlights the need for further research on the environmental toxicity of PAHs in combination with other stressors.

Summary: This study aimed to investigate the spatial and media distribution patterns of antibiotic resistance genes (ARGs) in Jiaozhou Bay, as well as the reasons behind these patterns. The results revealed that aminoglycoside and MLSB resistant genes predominated in all samples, with ARGs' relative abundance ranging from 10-6 to 10-2, 10-6 to 10-3, and 10-5 to 10-2 copies/16S rRNA in coastal water, bay water, and sediments, respectively. The significant spatial variation of ARGs was explained by the susceptibility of coastal water to human activities, while environmental physicochemical factors played a crucial role in bay water. The distribution variation between media was attributed to different assembly processes and the influence of environmental factors and heavy metals in water and sediments, respectively.

Summary: The pharmacologically relevant physicochemical properties of the antiandrogen drug bicalutamide (BCL) were determined for the first time. The study found that BCL had low solubility in water and n-hexane, but higher solubility in alcohols. Thermodynamic analysis showed that BCL preferred lipophilic delivery pathways in biological media.

Summary: In this study, the long-term spatiotemporal changes in hydrodynamics, antibiotics, antibiotic resistance genes (ARGs), class 1 integron gene (intI1), and microbial communities in a semi-enclosed estuary during ecological restoration were investigated. The restoration reduced common pollutants in the water, while ARGs showed noticeable seasonal and spatial variations. The distribution of ARGs and dominant antibiotic-resistant bacteria (ARB) were significantly affected by biological treatment and aerators in the estuary. Furthermore, microbial communities and intl1 were found to be key factors related to ARG dissemination.

Summary: By using molecular dynamic simulations, diffusion coefficients of binary supercritical water mixtures (species 1: H2O, species 2: H-2, CH4, CO, O-2, CO2) at high temperatures and pressures were calculated, showing that temperature and mole fraction play significant roles in determining self- and Maxwell-Stefan diffusion coefficients, while Fick diffusion coefficient can be considered constant at certain temperatures in binary mixtures. Overall, a general predictive model with shared modification factors for equations was developed.

Summary: The three-year field investigation in the eutrophic Pearl River in South China revealed that concentrations of different antibiotics in sediment were significantly correlated with the occurrence of blooms, with some antibiotics showing burial phenomena. Meanwhile, there was a positive correlation between chlorophyll a concentration and antibiotic concentration in sediment, while tetracycline concentration was inversely related to phytoplankton biomass.

Summary: This study investigated the concentrations and abundance of 11 antibiotics in water, sediment, and various aquatic organisms in the Pearl River, South China. The results showed that the bioaccumulation of antibiotics was positively correlated with their ionized form. Sediment ingestion was found to be a potential route of antibiotic exposure, as indicated by higher bioaccumulation in benthic organisms compared to fish. Additionally, only ciprofloxacin exhibited significant trophic magnification, suggesting the importance of metabolic biotransformation in driving the biomagnification of antibiotics.

Summary: The increasing concentration of endocrine disrupting compounds (EDCs) in the aquatic environment has irreversible effects on biota's endocrine and reproductive systems. This study measured the concentrations of seven common EDCs in fish, invertebrate species, and plankton collected from South China. The results showed that fish had the highest EDC concentrations, with 4-nonylphenol and bisphenol S being the predominant components. Trophic magnification factors (TMFs) were negatively correlated with in vitro biotransformation clearance rates (CL in vitro) and CYP450 enzymes activities, indicating that metabolism plays a significant role in the trophic transfer of EDCs.

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: 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: 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.
