Marine debris invasion and pollution assessment in mangrove wetlands in the northern South China Sea
AI summary Read the abstract
Researchers assessed the abundance, accumulation, sources, and fate of marine debris in seven mangrove wetland areas in the northern South China Sea between 2019 and 2020. They found plastics dominated debris (48.34%) with over 70% of all debris weight being land-based and more than 70% originating from coastal and recreational activities.
Abstract Mangrove wetlands as debris traps should receive more attention. Here, we assessed that the magnitude, accumulation, source and fate of marine debris in seven mangrove areas in the north South China Sea (MNSCS) (2019–2020). Marine debris with plastic dominating is invading the MNSCS at the low level. More than 70% of all debris weight with plastics (48.34% ) and fabrics (14.59%) is land-based, and more than 70% comes from coastal/recreational activities. More than 90% of all debris items with plastics (52.50%) and styrofoam(36.32%) is land-based, and more than 90% comes from coastal/recreational activities. The medium/large size debris are trapped in mangrove wetlands under the influenced conditions of local tidal level, debris item materials, and sizes. We expect that our study is helpful to determine the nature and significance of their risk and future marine debris management and the mangrove conservation and restoration.

Mapping and Potential Risk Assessment of Marine Debris in Mangrove Wetlands in the Northern South China Sea
AI summary Read the abstract
A comprehensive six-year survey of seven mangrove areas in the northern South China Sea found relatively low but plastic-dominated marine debris, with over 70% of debris by weight originating from land-based coastal and recreational activities. Medium and large debris items were preferentially trapped in mangroves based on tidal conditions, underscoring the role these ecosystems play in intercepting land-based plastic pollution.
Marine litter in mangroves: composition, magnitude, and impacts
AI summary Read the abstract
A field and literature review of marine litter accumulation in mangrove ecosystems documented diverse debris types dominated by single-use plastics and fishing gear, with litter altering physical habitat structure and posing ingestion and entanglement risks. Mangroves are highlighted as both a sink for marine litter and an ecosystem whose ecological functions are degraded by it.
Characteristics and distribution of microplastics in the coastal mangrove sediments of China
AI summary Read the abstract
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.
Microplastics on beaches and mangrove sediments along the coast of South China
AI summary Read the abstract
Microplastic concentrations in beach and mangrove sediments along the South China coast were higher in summer than winter, with fibres and fragments dominating, and mangrove sediments retaining significantly more particles than adjacent beaches, confirming mangroves as important sinks for coastal microplastic pollution.
The distribution, characteristics and ecological risks of microplastics in the mangroves of Southern China
AI summary Read the abstract
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.
