Summary: This study combines photocatalytic technology with constructed wetlands to efficiently remove antibiotic resistance genes (ARGs). Results show that photocatalysis and constructed wetlands together increase the effectiveness of ARGs removal, with different mechanisms for intracellular and extracellular ARGs. The addition of nano-TiO2 alters the microorganisms in constructed wetlands, leading to an increase in the removal of potential hosts for target ARGs.

Summary: The reuse of household greywater is increasing globally, however, wastewater and greywater treatment processes are not fully effective in removing all contaminants. The dynamics between emerging micropollutants and antibiotic resistance genes in greywater treatment systems are complex. More studies are needed to understand the fate and transport of emerging micropollutants, antimicrobial-resistant bacteria, and antibiotic resistance genes in microbial communities and soil properties.

Summary: The International Maritime Organization has set a target to reduce shipping greenhouse gas emissions by at least 50% in 2050 compared to 2008. Studies show that mitigation measures with negative costs are more likely to be implemented, but alternative maritime fuels have a lower implementation rate.

Summary: Antibiotic resistance genes (ARGs) carried by antibiotic resistant bacteria (ARB) are found in large numbers in wastewater, specifically in wastewater treatment plants (WWTPs). The presence of mobile genetic elements (MGEs), heavy metals, and emerging pollutants in WWTPs can impact the proliferation of ARGs. Additionally, the efficiency of ARGs removal in wastewater treatment processes is limited. It is important to summarize the research status of ARGs in WWTPs to reduce their potential harm to ecological environments and provide guidance for practical applications.

Summary: There is concern that the use and misuse of antibiotics can lead to an increase in antibiotic resistant genes (ARGs) in wastewater. Conventional wastewater treatment plants can release ARGs and antibiotic resistant bacteria (ARB) into natural water bodies. Constructed wetlands (CWs) offer a low-cost solution for wastewater treatment and have the potential to remove nutrients, pathogens, and ARB/ARGs.

Summary: Emission of antibiotics into riverine environments affects aquatic ecosystem functions and leads to the development of antibiotic resistance. The study found that river sections close to urban and livestock areas contain more antibiotics and antibiotic resistance genes (ARGs). Antibiotic concentration is correlated with ARG abundance in the water, indicating antibiotics play a critical role in ARG spread. Some antibiotics pose ecotoxicological risks to aquatic organisms and sediment. The Nanliujiang river with intensive livestock activities is contaminated by antibiotics and ARGs and faces high ecotoxicological and resistance selection risks.

Summary: Urban wastewater treatment plants (UWTPs) are crucial for reducing pollutant load and protecting water bodies, but they also emit antibiotic resistant bacteria and resistance genes, which have impacts on downstream environments. This study tested a set of biomarkers for antibiotic resistance monitoring and found that qPCR can be a cost-effective and technically accessible approach for monitoring wastewater and downstream environments.

Summary: Antibiotic resistance poses a significant challenge to public health and ecological safety in the 21st century. Urban wastewater treatment plants not only serve as reservoirs of antibiotic resistance genes and bacteria, but also contain various chemical pollutants. This review presents the actual concentration levels and mechanisms of antibiotic resistance drivers in such plants, including antibiotics, heavy metals, disinfectants, cosmetics and personal care products, non-antibiotic drugs, and microplastics. The importance of studying the actual activated sludge environment and future research directions are emphasized.

Summary: Our study in Jaipur City, India, found lower abundance of ARGs in a hospital wastewater treatment plant compared to municipal wastewater treatment plants, which showed enrichment of tetracycline and macrolide-lincosamide-streptogramin resistance genes. Hospital wastewater had a higher abundance of genes conferring resistance to disinfectant-related compounds. Additionally, a strong correlation was found between the numbers of ARGs and BMRGs potentially harbored by common hosts in wastewater systems with more chemicals.

Summary: In this study, magnetic activated carbon (MAC) was developed and used as a pre-treatment for ultrafiltration (UF) to simultaneously reduce dissolved effluent organic matter (dEfOM) and antibiotic resistance genes (ARGs). The hybrid process of MAC-UF showed superior removal efficiency compared to individual processes, reducing dEfOM by over 60% and achieving significant reduction of ARGs. Furthermore, MAC pretreatment significantly reduced membrane fouling, particularly irreversible hydraulic resistance. This new approach has important implications for reclaimed water security and UF technology promotion.

Summary: This study investigated the presence of PAHs in fresh waters and surface sediments on the western shore of Admiralty Bay over several sampling seasons. The results showed that biomass combustion and coal were the main sources of PAHs, with a limited contribution from petroleum sources. The study also indicated a minimal role of long-range atmospheric transport from South America in PAH pollution, with local activities being more closely associated with PAH contamination.

Summary: Antibiotic resistance poses a major human health threat, with global asymmetries in occurrence influenced by factors such as climate, socioeconomic status, and antibiotic use. Europe shows an increasing gradient of resistance from North to South and from West to East. A qualitative comparison between Poland in Central-East region and Portugal in South-West reveals differing levels of antibiotic consumption and resistance prevalence, with potential similar resistance loads in treated wastewater.

Summary: The amount of fly ash from sewage sludge incineration is increasing globally, posing a serious environmental problem. This study utilized sewage sludge ash (SSA) from a municipal sewage treatment plant to investigate its impact on the hydration heat process of cement mortars. The research found that SSA particles have irregular grain morphology and consist mainly of oxides such as CaO, P2O5, SiO2, and Al2O3. The presence of SSA in cement mortars decreased the rate of heat generation and total heat compared to control samples. Increasing the replacement of cement with SSA also led to a decrease in the 7-day compressive strength of the mortar samples.

Summary: This study investigated the bio-degradation kinetics of tetramethyl bisphenol F (TMBPF), a non-estrogenic alternative to bisphenol A (BPA). Batch biotransformation experiments were performed using activated sludge and liquid chromatography-Orbitrap-MS for BTP identification. Results showed that TMBPF degradation followed first-order reaction kinetics and depended on the initial concentration. Twelve BTPs were identified, and a proposed biodegradation pathway for TMBPF was suggested.

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.

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.
