ClearContamination 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.
Microplastic in mangroves: A worldwide review of contamination in biotic and abiotic matrices
This worldwide review analyzed 53 studies on microplastic contamination in mangrove sediments, water, and organisms across Asia, America, and Africa, finding that research is geographically limited and lacks wide-scale coverage of mangrove coastlines. Most studies characterized microplastic type, size, color, and morphology but did not assess ecological risks.
Microplastics pollution in mangrove ecosystems: A critical review of current knowledge and future directions
This review synthesizes available research on microplastic pollution in mangrove ecosystems, which act as buffers between land and sea and accumulate plastics from both marine and terrestrial sources. The authors identify key gaps in knowledge and call for more research on how microplastics affect these ecologically critical habitats.
Microplastics in mangroves with special reference to Asia: Occurrence, distribution, bioaccumulation and remediation options
This review examines microplastic contamination in Asian mangrove ecosystems, finding higher pollution levels near fishing, tourism, and industrial areas. Organisms throughout the mangrove food web, from shellfish to fish, accumulate microplastics based on their feeding habits and habitat. While mangrove plants can trap some microplastics in their roots, the widespread contamination of these coastal ecosystems raises concerns about the safety of seafood harvested from mangrove areas for human consumption.
Microplastics Presence in Rhizophora mangle Roots throughout Fishponds and Open Coasts in Moloka'i, Hawaii
This study found microplastics in the roots of red mangrove trees at both fishpond and open coast sites in Hawaii, documenting plastic contamination in a critical coastal habitat. Mangrove ecosystems are important nursery habitats for fish and shellfish, so microplastic contamination there has broader food chain implications.
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.
Non-native Rhizophora mangle as sinks for coastal contamination on Moloka'i, Hawai'i
Researchers studied microplastic and pesticide contamination in coastal areas of Moloka'i, Hawaii, comparing zones with invasive mangrove trees to open coastline. They found that mangrove roots concentrated both microplastics (up to 2,004 particles per kg) and the insecticide bifenthrin at high levels, acting as pollution sinks that could pose risks if these trees are removed.
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.
Impact of elevated environmental pollutants on carbon storage in mangrove wetlands: A comprehensive review
Researchers synthesized global studies on pollutant impacts in mangrove wetlands — which store about 10% of coastal ocean carbon — finding that microplastics reduce carbon stocks by 1-12% by impairing photosynthesis and destabilizing sediments, while heavy metals and oil spills compound the damage to these critical climate carbon sinks.
Assessing microplastic contamination levels in ghana's mangrove wetlands
Researchers investigated microplastic contamination levels in Ghana's mangrove wetlands, examining how the morphology of mangrove root systems traps and accumulates plastic particles of all sizes and assessing the threat posed to these ecologically critical coastal ecosystems.
A 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.
Assessing microplastic contamination levels in ghana's mangrove wetlands
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.
Role of mangrove forest in interception of microplastics (MPs): Challenges, progress, and prospects
This review examines how mangrove forests intercept and accumulate microplastics from terrestrial, marine, and atmospheric sources, identifying knowledge gaps in understanding the mechanisms, ecological impacts, and long-term fate of trapped microplastics in mangrove ecosystems.
