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.

Summary: Hydrogen peroxide (H2O2) and aeration were found to be effective in removing antibiotic resistance genes (ARGs) from mariculture sediments. The H2O2 group showed a 3.8-32.3% reduction in ARG abundance compared to the aeration group, and this reduction was associated with decreased bacterial population and diversity. Path modeling analysis revealed that the reduction of mobile genetic elements (MGEs) played an important role in ARG removal in the H2O2 group, while changes in bacterial community composition determined ARG reductions in the aeration group.

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: 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: This study used HT-qPCR to investigate the distribution of MRGs in estuarine sediments and found that their relative abundance decreased from the river inlet to the sea, with more significant decreases in the summer than in the winter. The abundance of MRGs was positively correlated with antibiotic residues, heavy metals, particle size, and organic carbon content of the sediment, but negatively correlated with seawater salinity, oxidation-reduction potential, and sediment pH. Additionally, MGEs were positively correlated with the abundance of MRGs, suggesting a link between antibiotic residues, MGEs, and the proliferation of MRGs in estuarine sediments.

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: Antibiotics used in mariculture contribute to the spread of antibiotic resistance genes (ARGs) and pose a threat to public health. This study investigated the efficiency and mechanism of removing ARGs from mariculture wastewater using the UV/H2O2 advanced oxidation process (AOP). The results showed that UV/H2O2 AOP effectively eliminated ARGs, with removal rates influenced by the concentration of the oxidizing agent and the location of the ARGs. The study highlights the potential of UV/H2O2 AOP as an effective approach for controlling ARGs in mariculture wastewater.

Summary: This study investigated the atmospheric oxidation mechanism and kinetics of tertiary amines using computational methods, focusing on trimethylamine (TMA) and triethylamine (TEA) as proxies. The results showed that the N-containing peroxy radicals play a key role in the oxidation of TMA and TEA, with a unique autoxidation mechanism observed for TMA compared to TEA. However, the TEA system may compete with a pathway dissociating into fragmental products.

Summary: This study investigated the effects of UV/chlorine treatment on the photophysical and photochemical properties of DOM using Suwannee River fulvic acid (SRFA) and Suwannee River natural organic matter (SRNOM) as representatives. The results showed that increasing chlorine dosage led to decreased absorbance of the two DOM samples and changes in their aromaticity, molecular weight, and electron-donating capacity. The quantum yields of excited triplet state of DOM, singlet oxygen, and hydroxyl radicals first decreased and then increased with increasing chlorine dosages in the UV/chlorine systems due to different reaction pathways. This study provides insights into the dynamic roles of DOM in the photodegradation of micropollutants.

Summary: Layered black phosphorus (BP) has great potential in various fields, but the interactions and parameters of BP adsorption with organics are lacking. In this study, molecular dynamic and density functional theory were used to calculate the energy and equilibrium constants of organics adsorbed onto BP. Gaseous phase adsorption was found to be more favorable than aqueous phase, and the affinity of aromatics to BP was similar to graphene. The established polyparameter linear free energy relationship model effectively predicted the adsorption capacity of organics onto BP.

Summary: This study investigated the degradation characteristics and pathways of cyclohexanecarboxylic acid (CHCA) in marine environments. The results showed that CHCA can be completely degraded with a pseudo-first-order kinetic reaction in the presence of nitrate. The proposed degradation pathways involve dehydrogenation of cyclohexane to cyclohexene, followed by ring-opening or cleavage reactions under aerobic or anaerobic conditions, respectively. Whole genome analysis revealed different pathways for nitrate removal under aerobic and anaerobic conditions. These findings provide insights into mitigating pollution from naphthenic acid and nitrate in marine environments with human activities.
