ClearCharacteristics and distribution of microplastics in the coastal mangrove sediments of China
A survey of mangrove sediments along China's coast found microplastics were ubiquitous, with concentrations and polymer types varying by proximity to human activity and hydrological conditions. The study shows that mangrove forests, which provide critical coastal ecosystem services, are accumulating significant quantities of plastic pollution.
Impacts of Microplastics on Mangroves - A Review
Mangrove forests act as natural traps for microplastics due to their dense root systems that slow water flow, leading to higher microplastic accumulation in mangroves than other coastal zones. This matters because the build-up harms mangrove plants at the cellular and physiological level, threatening these ecologically critical habitats that protect coastlines and support fisheries.
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.
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.
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.
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.
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.
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.
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.
Characterization, source, and retention of microplastic in sandy beaches and mangrove wetlands of the Qinzhou Bay, China
Researchers characterized microplastics in sediments from both sandy beaches and mangrove wetlands in Qinzhou Bay, southern China, finding higher abundances in mangrove sediments than beach sediments due to the trapping function of root systems. The study demonstrates that mangroves act as effective sinks for microplastic pollution in coastal zones.
Distribution and retention of microplastics in plantation mangrove forest sediments
Researchers investigated the spatial distribution and retention of microplastics in sediments of plantation mangrove forests, finding that mangrove plantations act as effective sinks for microplastics transported by ocean tides, with particle size and shape influencing where plastics accumulate within the forest structure.
Microplastics retention in different types of Mangrove forest in Xuan Thuy National Park, Vietnam
Researchers measured microplastic retention in three types of mangrove forest in Xuan Thuy National Park, Vietnam, and found that mangroves trap significant quantities of microplastics from coastal waters. Mangrove restoration projects could therefore help reduce microplastic loads in adjacent coastal waters as an ecosystem service. However, mangroves themselves accumulate microplastics, which may affect their ecological functions over time.
Preliminary Study on the Role of Mangroves in Entrapping Microplastics in Tuticorin Coast of Gulf of Mannar, Southeast Coast of India
Researchers compared microplastic concentrations in mangrove sediments versus open-beach control sites along the coast of southern India and found consistently higher levels within mangrove areas. Polyethylene and polypropylene fibers in the 1–3 mm range were most common, and weathering analysis confirmed significant environmental degradation of the particles. The findings suggest that mangrove root systems act as natural traps for microplastics, which has implications for both ecosystem health and the many coastal communities that rely on mangroves for fisheries and shore protection.
Evidence of elevated microplastic accumulation in Pacific Island mangrove sediments
Researchers found that mangrove sediments in Fiji contained nearly ten times more microplastics than surrounding non-mangrove areas, with consistent results across both urban and rural sites. Fibers were the most common type of microplastic found, and the contamination levels were comparable to heavily polluted regions elsewhere in the world. The study highlights that mangroves, while vital coastal ecosystems, may be acting as significant traps for microplastic pollution in Pacific Island nations.
Current status and trends of research on microplastic fugacity characteristics and pollution levels in mangrove wetlands
This systematic literature review analyzed the distribution, characteristics, and pollution levels of microplastics in mangrove wetlands globally, finding that mangroves act as significant traps for land-based plastics before they reach the open ocean. Fiber morphologies and polymer types reflected terrestrial sources, and microplastic density was highest near urban river inputs.
Microplastics in Singapore’s coastal mangrove ecosystems
Researchers sampled coastal mangrove ecosystems in Singapore and found microplastics throughout, demonstrating that mangrove habitats accumulate plastic pollution and raising concerns for the organisms that depend on these ecologically important coastal forests.
Mangrove forest: An important coastal ecosystem to intercept river microplastics
Mangrove forests along a Chinese coastline were found to act as effective interceptors of river-borne microplastics, trapping significant quantities of plastic particles before they could reach open coastal waters. The study highlights mangrove ecosystems as important natural filters for microplastic transport from land to sea, with implications for coastal conservation priorities.
Identifying patterns of microplastic accumulation in coastal vegetated habitats: A systematic review and meta-analysis
A meta-analysis of microplastic accumulation in coastal vegetated habitats found that mangroves have the highest microplastic concentrations compared to saltmarshes and seagrass beds, especially near urban centers and fishing zones. Nearly 40% of comparisons showed higher microplastic accumulation in vegetated versus unvegetated sites, with degraded habitats accumulating more plastics.
Mangroves as unique but understudied traps for anthropogenic marine debris: A review of present information and the way forward
This review examined mangroves as understudied traps for anthropogenic marine debris, noting that 18 of the top 20 plastic-emitting rivers are associated with mangrove coastlines. Mangroves efficiently accumulate debris through their dense root structures, yet are rarely included in coastal plastic monitoring programs.
Mangrove Health: A Review of Functions, Threats, and Challenges Associated with Mangrove Management Practices
This review describes how mangrove forests protect coastlines, store carbon, and support marine life, but are under increasing threat from development, pollution, and climate change. Mangrove loss matters for microplastic pollution because these ecosystems act as natural filters that can trap plastic particles before they spread further into the ocean and food chain.
ACCUMULATION OF MICROPLASTICS (<300 µM) IN MANGROVE SEDIMENTS OF BANDA ACEH CITY, INDONESIA
Researchers measured microplastic accumulation in mangrove sediments in Banda Aceh, Indonesia, finding up to 3,840 particles per kilogram of sediment — with plastic pellets and fibers smaller than 300 micrometers being the most common types — suggesting these coastal ecosystems are acting as significant traps for plastic pollution from nearby land and waterways.
Mangrove forests as traps for marine litter
Researchers surveyed 20 mangrove forests along the Red Sea and Arabian Gulf and confirmed that mangroves act as traps for marine plastic litter, with denser forests and proximity to shipping routes linked to higher debris accumulation. The study shows that ocean-based activities, not just land-based sources, are a major driver of plastic buildup in coastal mangrove ecosystems.
