ClearThe Effects of Polyethylene Microplastic Accumulation on Rhizophora mucronata Seedling Survival in the Mangrove Ecosystem of South Jakarta
Scientists found that tiny plastic particles in soil dramatically reduce the survival of young mangrove trees, with survival rates dropping from 80% in clean soil to just 20% in heavily polluted soil. This matters because mangrove forests protect coastlines from storms and flooding while filtering water that eventually reaches humans. As plastic pollution increases in coastal areas, we could lose these natural barriers that help protect communities and clean our environment.

Uptake, growth, and oxidative stress responses of Rhizophora mucronata (Poir. in Lam.) propagules exposed to high-density polyethylene microplastics
Researchers exposed mangrove propagules to environmentally relevant concentrations of high-density polyethylene microplastics for three months and found that the particles accumulated on root surfaces and translocated into the shoot system. The microplastics caused significant reductions in root length, plant height, and foliar area, along with increased oxidative stress indicators. The study suggests that microplastic pollution poses a real threat to mangrove growth and could ultimately affect the diversity and productivity of mangrove forests.

The study highlights an understudied threat to mangrove ecosystems and calls for greater attention to microplastic impacts on these critical coastal habitats.
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.

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.

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.
Effects of microplastics on carbon release and microbial community in mangrove soil systems
Researchers tested how microplastics affect carbon release and microbial life in mangrove soils at different depths. They found that while topsoil was largely unaffected, deeper soil layers released significantly more carbon dioxide when microplastics were present, particularly biodegradable types like polylactic acid. The study suggests that microplastic contamination in mangrove ecosystems could accelerate carbon loss from deeper soils by disrupting microbial communities and worsening nitrogen limitations.
Increased risk of heavy metal accumulation in mangrove seedlings in coastal wetland environments due to microplastic inflow
When mangrove seedlings were grown in coastal sediments contaminated with polystyrene and polymethyl methacrylate microplastics, they accumulated significantly more heavy metals -- up to 548% more -- particularly in their roots. The microplastics triggered oxidative stress in the plants and altered how heavy metals moved through the soil. This is concerning because mangrove ecosystems are nurseries for many seafood species, and increased heavy metal uptake could enter coastal food webs.
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.
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.
Ecological interception effect of mangroves on microplastics

Microplastics and heavy metals reshape mangrove rhizosphere microbiomes and compromise carbon fixation potential
Researchers investigated how microplastics and heavy metals together affect the microbial communities around mangrove tree roots. They found that combined pollution significantly reduced microbial diversity and shifted the balance of bacterial species, which in turn compromised the ability of these ecosystems to capture and store carbon. The study highlights that microplastic-metal co-contamination poses a compounding threat to mangrove ecosystems, which play an important role in coastal carbon storage.
