Anthropogenic marine debris and its dynamics across peri-urban and urban mangroves on Penang Island, Malaysia
Researchers tracked the accumulation of marine debris in urban and semi-urban mangroves on Penang Island, Malaysia, finding that debris abundance varied with season, tidal patterns, and proximity to urban areas. Mangroves act as debris traps, concentrating plastic waste including microplastics that filter through their root systems.
Classification of microplastic characteristics in surface water and sediments in the lower Mekong river (Vietnam) in the dry season
Researchers analyzed microplastic distribution and polymer composition at 17 locations along the Mekong River in Vietnam during the April 2024 dry season, collecting samples from both surface water and riverbed sediments and characterizing them by optical microscopy and FTIR spectroscopy. They found that microplastic densities were higher in more urbanized areas and were influenced by geographical location, transportation activities, population density, and local hydrological characteristics.
Occurrence and characteristics of microplastics in water and sediment samples along the red river to the gulf of tonkin, vietnam
Researchers surveyed microplastics in water and sediment along Vietnam's Red River from inland areas to the Gulf of Tonkin, documenting the types, sizes, and polymer compositions present. The findings show how a major river system acts as a pathway delivering plastic pollution from a densely populated landscape into coastal marine waters.
Distribution of Microplastics in the Beach Indicating Anthropogenic Sediments: Case Study in Can Gio HCM City, Vietnam
Researchers characterised microplastics in coastal sediments of Can Gio, Ho Chi Minh City, Vietnam across dry and rainy seasons, examining characteristics, composition, size, shape, and distribution through boreholes and excavations at identified cross-sections.
Macroplastic and microplastic contamination assessment of a tropical river (Saigon River, Vietnam) transversed by a developing megacity
Researchers assessed macroplastic and microplastic contamination in a tropical river in Vietnam, finding elevated pollution levels linked to urban and agricultural land use along the waterway.
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.
Characteristics of Microplastics and Their Affiliated PAHs in Surface Water in Ho Chi Minh City, Vietnam
Researchers characterized microplastics and associated polycyclic aromatic hydrocarbons (PAHs) in surface water across canals, the Saigon River, and coastal waters in Ho Chi Minh City, Vietnam, finding microplastics at all sites with the highest concentrations in urban canals and detecting co-occurring PAH contamination.
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.
Comparison of Microplastic Pollution in Beach Sediment and Seawater at UNESCO Can Gio Mangrove Biosphere Reserve
Microplastic concentrations in beach sand and seawater were compared across sites in the UNESCO Can Gio Mangrove Biosphere Reserve in Vietnam, with higher concentrations in sediments near boat traffic corridors and tourist areas, confirming that even protected biosphere reserves are contaminated and that local human activity drives spatial distribution patterns.
Occurrence and characteristics of microplastics in water and sediment samples along the red river to the gulf of tonkin, vietnam
This study characterized the occurrence and properties of microplastics in water and sediment samples along the Red River from inland Vietnam to the Gulf of Tonkin, mapping contamination levels across a major river system draining into the South China Sea. The findings help establish the scale of plastic inputs from Southeast Asian river systems, which are among the world's largest contributors to ocean plastic pollution.
