ClearOccurrence, Source Apportionment, and Risk Assessment of Antibiotics in Mangrove Sediments from the Lianzhou Bay, China
Researchers assessed the occurrence and ecological risks of 39 different antibiotics in mangrove sediments from Lianzhou Bay, China. They found antibiotics from multiple classes present at measurable concentrations, with aquaculture and urban discharge identified as primary sources. The study warns that antibiotic contamination in these sensitive coastal ecosystems may contribute to the spread of antimicrobial resistance.
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.
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.
Impact of the surrounding environment on antibiotic resistance genes carried by microplastics in mangroves
Researchers buried five plastic types in mangrove ecosystems with different surrounding environments and used qPCR to quantify antibiotic resistance genes (ARGs) on the plastic surfaces, finding higher ARG abundance in urban mangroves than in protected or aquaculture areas. Polypropylene and HDPE were preferred substrates for ARG-carrying bacteria, and proximity to human activities was the main driver of ARG distribution.
A review on microplastic pollution in the mangrove wetlands and microbial strategies for its remediation
Researchers reviewed the growing problem of microplastic pollution in mangrove wetland ecosystems and its effects on the biological communities that depend on these habitats. They found that microplastic exposure can substantially alter the microbial communities critical to nutrient cycling in mangrove environments. The review also explores microbial bioremediation strategies as a sustainable approach to addressing plastic pollution in these threatened coastal ecosystems.
An Examination of the Current Knowledge of Contaminants in Mangroves: Hawaii and Globally
This thesis comprehensively reviews contamination in mangrove ecosystems globally and in Hawaii, covering heavy metals, persistent organic pollutants, PAHs, pharmaceuticals, and microplastics as one of four main contaminant classes. The review identifies significant research gaps around how these pollutants affect mangrove biodiversity and pose risks to human populations, particularly as mangrove ranges shift with climate change. Understanding contaminant dynamics in mangroves matters because these ecosystems are used for fishing and coastal food production worldwide.
Microplastic Contamination in Water, Sediment, and Biota in Mangrove Forests
This review synthesized research on microplastic contamination in mangrove forest water, sediment, and biota, finding that mangroves act as both sinks and potential sources of microplastics due to their complex hydrodynamics, with ecotoxicological data on mangrove-specific organisms remaining limited.
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.
Mangrove degradation retarded microplastics weathering and affected metabolic activities of microplastics-associated microbes
Microplastic weathering was slower in degraded mangrove sediments than in intact mangroves, with degradation also altering the composition and metabolic activity of microplastic-associated microbial communities. The findings suggest mangrove ecosystem health influences how rapidly microplastics degrade and what ecological roles microplastic-associated microbes play in these coastal environments.
Bacterial Diversity in Estuarine Sediments in Brazilian Coastal: a Focus in Bacterial Resistance
This paper is not about microplastics; it characterizes bacterial diversity and antibiotic resistance genes in estuarine sediments from Brazilian mangroves, examining how human effluents shape microbial communities.
Contamination in mangrove ecosystems: A synthesis of literature reviews across multiple contaminant categories
This review synthesizes research on five classes of contaminants in mangrove ecosystems, including microplastics, heavy metals, and organic pollutants. Microplastic levels in mangroves varied widely and lack established safety thresholds, while other pollutants were sometimes found at levels harmful to wildlife. Since mangrove ecosystems support fisheries and coastal communities, contamination of these environments could affect human food sources and livelihoods.
Insights into co-occurrence characteristics and interplay of microbial communities and environmental pollutants on biofilm-colonized microplastics in mangrove ecosystems
Researchers conducted an in situ study in mangrove ecosystems examining how microplastics accumulate biofilms over time, finding progressive development of microbial communities across seasons, polymer types, and exposure durations, with heavy metals and persistent organic pollutants co-occurring on microplastic surfaces.

Researchers assessed microplastic contamination levels in mangrove wetlands in Ghana, examining how mangrove tree morphology facilitates plastic accumulation and what concentrations and polymer types are present in these coastal ecosystems. The study addressed threats to mangrove ecological services including water quality improvement, carbon sequestration, and coastline protection posed by plastic pollution.
Charting the microplastic menace: A bibliometric analysis of pollution in Malaysian mangroves and polypropylene bioaccumulation assessment in Anadara granosa
Researchers surveyed microplastic contamination in Malaysian mangrove ecosystems and tested how a common shellfish species accumulates polypropylene particles. They found microplastics in all sediment and water samples, with the shellfish readily taking up fiber-shaped particles. The estimated dietary intake suggests that consumers of these shellfish could ingest hundreds of microplastic particles per year, highlighting food safety concerns.
Finding microbial composition and biological processes as predictive signature to access the ongoing status of mangrove preservation
Using DNA sequencing, researchers mapped the microbial communities in mangrove soils of a large Brazilian bay, comparing pristine and polluted areas near a petroleum refinery. Polluted mangroves showed increased populations of bacteria adapted to breaking down hydrocarbons, while beneficial organisms like diatoms declined. While focused on oil pollution, the findings are relevant to microplastics research because mangroves act as filters for coastal pollution, and degraded mangrove ecosystems are less effective at trapping microplastics before they reach the ocean.
Meta-analysis unravels the complex combined toxicity of microplastics and antibiotics in aquatic ecosystems
A meta-analysis of 730 datasets found that microplastics amplify antibiotic accumulation in aquatic organisms and worsen effects on growth, development, and immune function, but paradoxically appear to mitigate reproductive toxicity from antibiotics. The impact depends on biological response pathway, microplastic concentration, antibiotic properties, and exposure time, with an inverse relationship between antibiotic toxicity and both microplastic concentration and exposure duration.
Plastic pollution in mangrove ecosystems: A global meta-analysis
This meta-analysis pooled global data on plastic pollution in mangrove ecosystems and found that these critical coastal habitats act as natural plastic traps. Mangroves accumulate significant amounts of both large plastic debris and microplastics due to their complex root structures. Since mangroves serve as nurseries for fish and seafood species that people eat, plastic contamination in these ecosystems could affect the food chain.
