Researchers investigated the co-occurrence of microplastics and chlorinated persistent organic pollutants in coastal wetlands of Zhejiang, China, finding microplastics in 100 percent of samples. Although wetland microplastic levels were lower than other land types, the plastics showed strong capacity to adsorb and concentrate toxic organic chemicals. The study highlights the combined contamination risk that microplastics and persistent pollutants pose to sensitive coastal ecosystems.

Researchers measured microplastic concentrations and polychlorinated biphenyl (PCB) levels at six sites along the urbanized Langat River in Malaysia, finding microplastics acting as vectors that adsorb and transport PCBs with concentrations highest at sites with the greatest industrial activity.
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.
Microplastics in mangrove sediments of the Pearl River Estuary, South China: Correlation with halogenated flame retardants' levels
Microplastic concentrations in Pearl River Estuary mangrove sediments were high by global standards, averaging 851 items per kilogram, and significantly correlated with population density and GDP in the region. Several types of halogenated flame retardants in the sediments were also correlated with microplastic abundance, suggesting shared pollution sources.
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.
Coupling of microplastic contamination in organisms and the environment: Evidence from the tidal flat ecosystem of Hangzhou Bay, China
Researchers surveyed microplastic contamination across the tidal flat ecosystem of Hangzhou Bay, China, examining both sediment and organisms. They found that microplastic characteristics in organisms closely mirrored those in the surrounding environment, indicating a tight coupling between environmental and biological contamination. The study provides evidence that estuarine ecosystems serve as key pathways for terrestrial microplastics entering the ocean.
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.
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.
Distribution, characteristics, and human exposure to microplastics in mangroves within the Guangdong-Hong Kong-Macao Greater Bay Area
Researchers mapped microplastic distribution across three mangroves in the Greater Bay Area of southern China, finding concentrations up to 1,600 particles per kilogram with higher levels at forest fringes, and assessed potential human exposure pathways.
