ClearMicroplastics in ports worldwide: Environmental concerns or overestimated pollution levels?
This review analyzed microplastic pollution data from 78 ports worldwide and found that port environments can harbor significant concentrations of microplastics in water, sediment, and marine life. About 23% of studied ports had microplastic levels in sediment above the threshold predicted to cause ecological harm. Since ports are connected to fisheries and coastal communities, this pollution could affect both marine ecosystems and the seafood supply chain.
Correction to: Microplastics in seawater: sampling strategies, laboratory methodologies, and identification techniques applied to port environment

Microplastics in Harbour Seawaters: A Case Study in the Port of Gdynia, Baltic Sea
Microplastics were measured in five basins of the Port of Gdynia in the Baltic Sea across four seasons, finding concentrations of 0.082-0.524 mg per cubic meter, with polyolefins dominant and fragments and fibres the most common shapes in harbour surface waters.
Microplastic Pollution and Monitoring in Seawater and Harbor Environments: A Meta-Analysis and Review
This meta-analysis reviews microplastic pollution levels in seawater and harbors worldwide, finding that contamination is widespread and persistent. The research matters for human health because marine microplastics enter the food chain through fish and shellfish, representing a significant route of exposure for seafood consumers.
Monitoring and Assessment of Microplastic Pollution in Coastal Zones: Sampling Methods and Spatial Distribution Characteristics
This review examines sampling methods and spatial distribution characteristics of microplastic pollution in coastal zones, synthesizing approaches for monitoring these key environmental interfaces. Researchers found that coastal zones serve as major sinks and dispersal areas for microplastics, with sampling methodology significantly influencing reported concentrations and distribution patterns.
Microplastic pollution in the marine waters and sediments of Hong Kong
Seasonal surveys of surface water and sediments across four coastal locations in Hong Kong found microplastics at all sites, with the highest concentrations in the most urbanized harbor areas. This first comprehensive study of Hong Kong coastal waters reveals that even heavily trafficked port environments accumulate large quantities of microplastic pollution.
Quantitative Analysis of Urban Microplastic Dissemination and Accumulation in Marine Ecosystems: Pathways, Processes, and Impacts
Researchers used water and sediment sampling across urban, riverine, and marine environments to quantify microplastic pathways from cities into marine ecosystems, finding the highest concentrations in urban areas linked to industrial activity and poor waste management. Polyethylene, polypropylene, and PET were the most common polymer types, with seasonal peaks in concentration tracking periods of high rainfall and urban runoff.
Progress on microplastics pollution and its ecological effects in the coastal environment
This review systematically summarizes a decade of research on microplastic pollution and its ecological effects in coastal environments worldwide, identifying persistent technical challenges in sampling standardization, particle identification, and ecological impact assessment. Researchers highlight the need for unified methodologies to better understand the sources, fate, and biological consequences of coastal microplastic contamination.
