Summary: Antibiotic pollution poses urgent threats to public health and microbial-mediated ecological processes. This study explores the effects of increasing antibiotic pollution on the assembly of sediment microeukaryotes. The results show that the structures of sediment microeukaryotic community are substantially altered by nutrient and antibiotic pollutions, and certain taxa of microeukaryotes can accurately predict in-situ antibiotic concentration.

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: Misuse and overuse of antibiotics have led to the rise of antimicrobial resistance. In agricultural soils, antibiotics and antibiotic resistance genes (ARGs) are mostly found due to the application of livestock and organic wastes. Cattle manure, chicken manure, swine manure, and sewage sludge are the primary sources of antibiotics and ARGs in agricultural soils. Sulfonamides, tetracyclines, fluoroquinolones, and corresponding ARGs are the major types of pollution. Land-use type, soil, and climatic factors affect the concentrations of antibiotics and abundances of ARGs. Mobile genetic elements (MGEs), especially the sul1 gene, play a vital role in promoting the dissemination of ARGs. Better management of antibiotic and ARG contamination in agricultural soils is important for human health.

Summary: The overuse of antibiotics has caused serious concerns worldwide as it may lead to significant changes in soil microbial communities, thereby threatening soil ecosystems. However, the effects of antibiotics on soil microbial biomass and community structure on a global scale are still unclear. Using 66 paired observations, we conducted one of the first global meta-analyses to evaluate the effects of various antibiotics on soil microbial communities and explore the underlying mechanisms. Our findings show that antibiotics suppressed soil microbial biomass, bacterial biomass, and fungal biomass, with the ratio of bacteria to fungi biomass decreasing for all antibiotic types. The negative effects of antibiotics on soil microbial community and bacteria biomass diminished over time, and the response of bacteria biomass to antibiotics varied with latitude, regulated by temperature, precipitation, soil pH, and total nitrogen.

Summary: Paddy soils are potential hotspots for combined contamination with arsenic and antibiotics. This study investigated the dynamic response of As biotransformation genes (ABGs) and antibiotic resistance genes (ARGs) in paddy soils. The results showed that As stress increased the abundance of ARGs and mobile genetic elements (MGEs), posing a risk of antimicrobial resistance dissemination. Manure amendment increased the abundance of ABGs, enhancing As mobilization and methylation, and posing a risk to food safety.

Summary: Coastal marine ecosystems have long been threatened by various pollutants, with increasing concern about the accumulation and impacts of antibiotics. The discharge of antibiotics from aquacultures into marine environments, especially through large rivers, is a significant source. The potential influence of imported antibiotics on bacterial communities in coastal waters, particularly in the sea surface microlayer (SML), where antibiotics can accumulate and contribute to the spread of antibiotic resistance, is discussed.

Summary: The aim of this investigation was to examine the microbial populations and their resistance patterns towards antibiotics, including the impact of nitrogen metabolism in response to the reintroduction of antibiotics, as well as the presence of resistance genes in sediments from shrimp ponds that have been utilized for extended periods of 5, 15, and over 30 years. Results showed that the sediments exhibited a high prevalence of Proteobacteria, Bacteroidetes, Planctomycetes, Chloroflexi, and Oxyphotobacteria as the most abundant bacterial phyla, accounting for 70.35-77.43% of the total bacterial community. The five most abundant phyla of fungi detected in all sediments, namely Rozellomycota, Ascomycota, Aphelidiomycota, Basidiomycota, and Mortierellomycota, constituted 24.26-32.54% of the total fungal community. It was highly probable that the Proteobacteria and Bacteroidetes phyla serve as the primary reservoir of antibiotic-resistant bacteria (ARB) in the sediment, which included various genera like Sulfurovum, Woeseia, Sulfurimonas, Desulfosarcina, and Robiginitalea.

Summary: Surface runoff is a main pathway for emerging pollutants, including antibiotics, antibiotic-resistant bacteria, and antibiotic resistance genes, to enter marine sediments. This study investigates the impact of emerging pollutants on the fate of antibiotic resistance genes in marine sediments from different seas in China. The results show that antibiotic exposure generally decreases the relative abundance of most antibiotic resistance genes, but there are exceptions with increased abundance observed in certain conditions. The findings suggest that dosing with emerging pollutants does not increase antibiotic resistance gene abundance in marine sediments.

Summary: This review critically analyzes the use of carbon based materials (biochar and hydrochar) for removing antibiotics from wastewater and water. Biochar and hydrochar both show excellent performance for adsorptive removal of antibiotics, with hydrochar having a higher adsorption capacity than biochar for tetracyclines. The key mechanisms for antibiotic adsorption onto biochar/hydrochar surfaces include 7C-7C electron donor-acceptor interactions and H-bonding. Thermodynamics studies indicate that the sorption process is mostly spontaneous and endothermic. Overall, the use of biochar/hydrochar for removing antibiotics from water has significant potential from both economic and environmental perspectives.

Summary: This review investigates the occurrence and impact of antibiotics in the environment, with particular focus on the interaction between antibiotics and humic substances (HS) and their influence on the dissemination of antibiotic-resistance genes. Quantitative data and proposed mechanisms of antibiotic-HS interaction are provided, along with discussions on the challenges of quantifying this interaction. Successful examples of using humic-based sorbents for antibiotic removal from water systems are given. The review also summarizes the various effects of HS on the dissemination of antibiotic-resistance genes and suggests the importance of characterizing HS properties for assessing the environmental consequences of antibiotic-HS complex formation.

Summary: The extensive use of macrolide antibiotics has led to their frequent detection in aquatic environments, affecting water quality and ecological health. This study analyzes the sources, distribution, fate, ecotoxicity, and global risk assessment of macrolide antibiotics based on recent literature. The results show that there are eight main sources of macrolide antibiotics in the water environment, and the most polluted water bodies are wastewater treatment plants and densely inhabited areas. Adsorption, photodegradation, and bioremoval are the main attenuation mechanisms in natural water environments. Macrolide antibiotics have ecotoxic effects on microalgae, crustaceans, fish, and invertebrates, causing oxidative stress and affecting gene expression. Over 50% of reported water bodies represent medium to high risk to microalgae. Further research on antibiotic removal technologies, combined ecotoxicity of antibiotic mixtures, and accurate ecological risk assessment models is encouraged.

Summary: Antibiotic resistance is a major challenge in human and clinical settings, as well as an environmental problem. This study investigated the resistome of microbial communities at four sites along the Yucatan coast, uncovering a diverse range of antibiotic resistance genes (ARGs) with varying enrichment levels. The findings suggest that ARGs are present in both preserved and contaminated areas, with high levels detected in sediments of the preserved area possibly due to submarine groundwater discharge. Overall, this study provides important insights into the current state of antibiotic resistance in the Yucatan coast, contributing to the understanding and management of ARGs pollution in the environment.

Summary: This study investigated the geographic patterns of antibiotic resistance genes (ARGs) in coastal sediments of the East China Sea. The results showed higher richness and abundance of ARGs in bay samples compared to nearshore and offshore samples. The distance to coastline (DTC) was negatively correlated with the richness and/or abundance of ARGs. Nutrition-related variables and metals/metalloid were significantly correlated with the composition of antibiotic resistome, indicating that terrestrial disturbances play a major role in shaping coastal sediment antibiotic resistomes.
