ClearUptake, 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.
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.
Distinct microplastics abundance variation in root-associated sediments revealed the underestimation of mangrove microplastics pollution
This study characterized how microplastic abundance varies across root hair, rhizosphere, and non-rhizosphere zones in mangrove sediments, finding that root structures significantly influence microplastic trapping and migration patterns within mangrove ecosystems.
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.
The 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 drastically reduced the survival of mangrove tree seedlings, with only 20% surviving in heavily polluted conditions compared to 80% in clean soil. This matters because mangrove forests act as natural barriers that protect coastal communities from storms and flooding, while also filtering pollution from water before it reaches the ocean. As microplastics continue to accumulate in our environment, they could damage these crucial ecosystems that help keep our coastlines and water supplies healthy.
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.
Effects of microplastics and heavy metal stress on the growth and physiological characteristics of pioneer plant Avicennia marina
Researchers studied how mangrove plants respond to combined pollution from microplastics and heavy metals at levels found in the environment. The combination caused more oxidative stress and growth problems than either pollutant alone, disrupting the plants' defense systems. Since mangroves protect coastlines and filter water for coastal communities, damage to these ecosystems from microplastic-heavy metal pollution could have indirect effects on human well-being.
The 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.
Mangrove degradation retarded microplastics weathering and affected metabolic activities of microplastics-associated microbes
Microplastic weathering was slower in degraded mangrove sediments than in intact mangroves, with degradation also altering the composition and metabolic activity of microplastic-associated microbial communities. The findings suggest mangrove ecosystem health influences how rapidly microplastics degrade and what ecological roles microplastic-associated microbes play in these coastal environments.
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.
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.
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.

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.
Insights into co-occurrence characteristics and interplay of microbial communities and environmental pollutants on biofilm-colonized microplastics in mangrove ecosystems
Researchers conducted an in situ study in mangrove ecosystems examining how microplastics accumulate biofilms over time, finding progressive development of microbial communities across seasons, polymer types, and exposure durations, with heavy metals and persistent organic pollutants co-occurring on microplastic surfaces.
Preliminary assessment of microplastic in rhizosphere and non-rhizosphere region of mangrove at four locations along Karachi coast, Pakistan
Researchers assessed microplastic distribution in rhizosphere and non-rhizosphere mangrove sediments at four sites along the Karachi coast, finding 14,960 particles with slightly higher counts in non-rhizosphere zones. Beads were the most common particle type, and FTIR confirmed polyethylene and polypropylene as dominant polymers.
Distribution characteristics of microplastics in the soil of mangrove restoration wetland and the effects of microplastics on soil characteristics
Researchers measured microplastic distribution in soils of a mangrove restoration wetland with different planting densities, finding an average abundance of 217 MPs per kilogram of dry soil with higher concentrations in denser planting zones. MPs in the soil also altered wetland soil physicochemical properties including bulk density and organic matter content.
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.
Are mangrove ecosystems plastic accumulation zones?
Researchers monitored macroplastic and microplastic pollution across nine mangrove sites on Cebu Island, Philippines, for over a year using paired removal and reference plots, finding that mangrove ecosystems function as significant plastic accumulation zones with differing dynamics between landward and seaward zones.
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.
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.
