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.
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.

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.
Revealing Microplastic Contamination in Mangrove Sediments from Setiu Wetlands, Malaysia
Researchers found 2,292 microplastic particles per kilogram of sediment in the mangrove wetlands of Setiu, Malaysia, with over 80% being tiny fibers likely from fishing gear and packaging. Areas near aquaculture operations had the highest contamination levels, and the microplastic surfaces showed signs of environmental degradation that could make them more toxic. Mangrove ecosystems act as natural traps for microplastics, concentrating pollution in habitats that are vital for fisheries and coastal protection.
Microplastics and accumulated heavy metals in restored mangrove wetland surface sediments at Jinjiang Estuary (Fujian, China)
Microplastics in restored mangrove wetland sediments in China were found in higher concentrations than in adjacent mudflats, suggesting that mangrove restoration itself may promote plastic accumulation. Surface analysis of microplastics revealed the presence of toxic metals including chromium, zinc, lead, and cadmium, indicating plastics as a carrier for these pollutants.
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.
Distribution, Diversity, and Ecological Risks of Microplastics in Mangrove Ecosystems of a Southeastern Chinese Estuary
Researchers examined microplastic contamination in mangrove sediments of the Zhangjiang Estuary in southeastern China, finding an average abundance of about 220 items per kilogram. The study found that interior mangrove habitats accumulated significantly more microplastics than edge zones, and abundance declined from upstream to downstream, suggesting terrestrial runoff as a primary source.
Occurrenceand characteristics of microplastics in benthic species from mangrove wetlands of Hainan, South China
Researchers found microplastics in 10 species of benthic organisms — including crabs, bivalves, and snails — across seven mangrove areas in Hainan, China, confirming that mangrove ecosystems and the organisms that inhabit them are significantly contaminated by microplastic pollution.
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.
Multidimensional Assessment of Microplastic Pollution in Mangrove Wetlands: Driving Mechanisms, Carbon Contribution, and Ecological Risk
Scientists found tiny plastic particles called microplastics throughout mangrove wetlands in China, with the highest levels in areas used for fishing and fish farming. These plastic particles are building up in the sediment and water, creating pollution hotspots that pose moderate ecological risks to these important coastal ecosystems. This matters because mangroves help protect coastlines and support marine life that humans depend on for food, so plastic pollution in these areas could ultimately affect our food supply and coastal protection.
[Occurrence Relationship Between Microplastics and Heavy Metals Pollutants in the Estuarine Sediments of Poyang Lake and the Yangtze River].
This study analyzed microplastic and heavy metal concentrations in sediments at the junction of Poyang Lake and the Yangtze River in China, finding substantial microplastic abundance (averaging ~982 particles/kg) that correlated with levels of copper, cadmium, lead, zinc, and chromium. The co-occurrence of these pollutants raises concern that microplastics and heavy metals may compound each other's environmental risks in this region.
[Distribution and Settlement of Microplastics in the Surface Sediment of Yangtze Estuary].
Researchers found microplastics in surface sediments at six sites in China's Yangtze River estuary, with concentrations varying by location and season. The study documents significant plastic contamination in this major coastal zone, raising concerns about ecosystem health and entry of microplastics into the marine food web.

Researchers profiled microplastic abundance with depth in sediment cores from the Kuala Gula Mangrove in Malaysia, finding 25-130 items per kg dry weight and highest concentrations near rivermouth sites, demonstrating that mangrove sediments are significant microplastic sinks.
The dual role of coastal mangroves: Sinks and sources of microplastics in rapidly urbanizing areas
Researchers studied microplastic dynamics in mangrove ecosystems along two rivers and a coastal mangrove park in China's Pearl River Estuary. They found that mangroves play a dual role, acting as both sinks that trap microplastics and sources that release them back into the environment. The study highlights that rapid urbanization significantly increases microplastic loads in these sensitive coastal ecosystems.
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.

Abundance and distribution of microplastics in tropical estuarine mangrove areas around Penang, Malaysia
This study documented microplastic pollution in tropical mangrove estuaries around Penang, Malaysia, finding thousands of plastic particles in both water and sediment samples. Concentrations were particularly high near the more urbanized Seberang Perai area, where sediment contained up to 4,000 particles per kilogram. The research highlights that tropical mangroves, which serve as important nursery habitats for marine life, are accumulating significant amounts of microplastic pollution.
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.
Spatial retention, absorption, transport, and enrichment of microplastics in mangrove sediment complex system
This study investigated how microplastics are distributed and transported within mangrove sediments in a Chinese coastal wetland. The researchers found that mangrove roots and sediment layers trap microplastics, but the particles can migrate deeper into the soil over time through water movement and biological activity. Since mangroves serve as nurseries for many fish species, microplastic accumulation in these ecosystems could affect marine food chains and ultimately human seafood consumption.
