ClearA review of antibiotic accumulation, degradation and ecological risk in typical mangrove ecosystems
This bibliometric and meta-analysis review synthesizes research on antibiotic accumulation and degradation in mangrove ecosystems, finding that sediment properties drive antibiotic buildup while specific bacteria mediate biodegradation — a balance further disrupted by co-contaminants such as microplastics and heavy metals. The review warns that antibiotic contamination in mangroves promotes the spread of antibiotic resistance genes and disrupts essential ecosystem functions like carbon and nitrogen cycling.
A systematic review of sources, occurrence, behavior and risks of global marine antibiotics
This systematic review of global marine antibiotic contamination found that sulfamethoxazole is the most frequently detected antibiotic in seawater, sediment, and marine organisms, with the highest concentrations along coastal China. Coexisting contaminants like microplastics may enhance antibiotic impacts and drive antibiotic resistance gene development in marine environments.
Microplastics accumulation in mangroves increasing the resistance of its colonization Vibrio and Shewanella
Researchers found that microplastics accumulating in mangrove sediments harbored antibiotic-resistant bacteria, predominantly Vibrio parahemolyticus, Vibrio alginolyticus, and Shewanella, with 100% of mangrove isolates showing elevated resistance. The study highlights microplastics as ecological colonization sites that may amplify antibiotic resistance risks in coastal ecosystems.
Antibiotic resistance genes might serve as new indicators for wastewater contamination of coastal waters: Spatial distribution and source apportionment of antibiotic resistance genes in a coastal bay
Researchers found that antibiotic resistance genes (ARGs) — DNA sequences that make bacteria immune to antibiotics — were significantly elevated near wastewater discharge points in a Chinese coastal bay, suggesting ARGs could serve as sensitive new indicators of sewage contamination in marine waters. Wastewater treatment plants and polluted rivers were identified as the primary sources driving ARG distribution patterns.
The distribution, characteristics and ecological risks of microplastics in the mangroves of Southern China
Microplastics were found to be widespread in mangrove sediments across Southern China, with higher concentrations in areas closer to urban development and aquaculture. The study highlights mangroves as accumulation zones for microplastic pollution, which could threaten these ecologically important coastal ecosystems.
Mangrove plastisphere as a hotspot for high-risk antibiotic resistance genes and pathogens
This study found that microplastics in mangrove ecosystems serve as hotspots for antibiotic resistance genes and disease-causing bacteria. Polyethylene, polystyrene, and PVC surfaces incubated in mangrove sediments harbored significantly more high-risk resistance genes than the surrounding environment. This is concerning because mangroves are important coastal habitats, and microplastics there could help spread drug-resistant infections to wildlife and potentially to humans.
An Overview of Antibiotics as Emerging Contaminants: Occurrence in Bivalves as Biomonitoring Organisms
Researchers reviewed the occurrence of antibiotic residues in bivalve mollusks used as biomonitoring organisms across European, American, and Asian coastlines. They found that macrolides, sulfonamides, and quinolones were the most frequently detected antibiotic classes, though the health risk from consuming contaminated bivalves was generally assessed as negligible. The study emphasizes the importance of continued monitoring to prevent the development of antimicrobial resistance from environmental antibiotic contamination.
Effects of tidal action on the stability of microbiota, antibiotic resistance genes, and microplastics in the Pearl River Estuary, Guangzhou, China
Researchers used 16S rRNA gene sequencing to study microbial diversity and the distribution of antibiotic resistance genes and microplastics in the Pearl River Estuary across areas with different land uses. The study found that tidal action influenced the stability and distribution of microplastics and antibiotic resistance genes, with different land use types showing distinct patterns of contamination.
A Review of the Distribution of Antibiotics in Water in Different Regions of China and Current Antibiotic Degradation Pathways
This review summarized the spatial and temporal distribution of antibiotic contamination across major Chinese water bodies, identifying livestock farming, pharmaceutical manufacturing, and aquaculture as primary sources and reviewing current biological and physicochemical degradation pathways.
Review on Biogeochemical Characteristics of Typical Antibiotics in Groundwater in China
A systematic review of antibiotic contamination in Chinese groundwater found 65 antibiotics detected across the country, with sulfonamides and quinolones most studied, maximum concentrations reaching 47,444.5 ng/L in some locations, and ecological risk mostly low to medium across monitored areas.
Assessing the Interrelationship Between Microplastics and Polychlorinated Biphenyls Contamination in Chinese Mangrove Sediment
Researchers quantified polychlorinated biphenyl (PCB) concentrations on microplastics extracted from mangrove sediments across representative sites in China, investigating the interrelationship between MP pollution dynamics and PCB contamination in these critical intertidal ecosystems. The study reveals how mangrove sediments accumulate both MPs and co-associated hydrophobic organic contaminants, highlighting combined pollution risks.
Abundance and characteristics of microplastics in the mangrove sediment of the semi-enclosed Maowei Sea of the south China sea: New implications for location, rhizosphere, and sediment compositions
Microplastics were widespread in mangrove sediments of the semi-enclosed Maowei Sea in southern China, with concentrations influenced by location within the mangrove, proximity to roots, and sediment composition. The study provides new insight into how mangrove ecosystems trap and accumulate microplastics, raising concerns for the health of these ecologically important coastal habitats.
