Occurrence and distribution of antibiotics in groundwater, surface water, and sediment in Xiong'an New Area, China, and their relationship with antibiotic resistance genes

Caixia Fu et al.

Summary: This study investigated the contamination and ecological risks of 39 antibiotics in Xiong'an New Area, China, revealing potential antibiotic pollution in multiple environmental media and the selection pressure of antibiotics on antibiotic resistance genes (ARGs). It was found that surface water could be a possible source of antibiotic contamination in groundwater, and antibiotics like AMX posed the highest risk and should be controlled as a priority. The study highlighted the significant interaction between different media and the need for measures to prevent more serious pollution.

Effects of environmental aging on the adsorption behavior of antibiotics from aqueous solutions in microplastic-graphene coexisting systems

Ningning Liu et al.

Summary: This study investigates the adsorption behavior of microplastics (MPs) and graphene oxide (GO) in aquatic environments, with increased adsorption capacity of aged MPs and enhanced adsorption of antibiotics in aged MPs-GO/rGO coexisting systems. The research provides insights into the environmental behavior of MPs and graphene, offering guidance on strategies for preventing antibiotic migration in MPs-GO/rGO coexisting systems.

UV-aging of microplastics increases proximal ARG donor-recipient adsorption and leaching of chemicals that synergistically enhance antibiotic resistance propagation

Qingbin Yuan et al.

Summary: This study systematically investigated the effects of microplastic aging on bacterial horizontal gene transfer. The results showed that aging increased the efficiency of antibiotic resistance gene transfer from microplastics to recipient bacteria, possibly due to increased specific surface area and affinity for the gene vectors. Additionally, aged microplastics released more organic compounds, induced ROS generation, increased cell permeability, and upregulated genes associated with gene transfer. The findings highlight the significance of microplastic aging in the environmental dissemination of antibiotic resistance and other gene transfer processes.

Microplastics as vectors of the antibiotics azithromycin and clarithromycin: Effects towards freshwater microalgae

Miguel Gonzalez-Pleiter et al.

Summary: This study reveals that microplastics can serve as carriers of chemicals toxic to aquatic microorganisms, impacting the growth and chlorophyll content of cyanobacteria. Antibiotics sorbed on microplastics can be released upon contact with water, leading to observed toxicity to cyanobacteria.
