Microplastic in bivalves of an urbanized Brazilian estuary: Human modification, population density and vegetation influence
Researchers measured microplastic contamination in oysters, clams, and mussels from a heavily urbanized estuary in Brazil, finding that industrial and port activities were stronger predictors of contamination than population density. Clams accumulated the most microplastics, and the study highlights how shellfish from polluted coastal areas can serve as indicators of the microplastic levels humans may be exposed to through seafood.
Impact of Microplastic in Mexican Coastal Areas Using Mussels ( Mytilus spp.) as Biomonitors
This study used mussels as bioindicators to assess microplastic contamination along the Mexican Pacific coast, finding higher levels of microplastics and associated heavy metals in more urbanized areas. The results suggest potential health risks for people consuming seafood from contaminated coastal areas.
Microplastics in Mediterranean Mussel Mytilus galloprovincialis: Comparison between Cultured and WildType Mussels from the Northern Adriatic
Researchers assessed microplastic contamination in the digestive glands of Mediterranean mussels collected from pristine, aquaculture, and port areas along the northern Adriatic coast. The highest contamination was found in mussels from a Croatian marina, with the smallest particles in the 5-to-10-micrometer range being the most prevalent. The study highlights that mussels accumulate microplastics regardless of their environment, with port areas showing notably higher contamination levels.
Study of Microplastics and Inorganic Contaminants in Mussels from the Montenegrin Coast, Adriatic Sea
Researchers analyzed mussels (Mytilus galloprovincialis) from three sites in Montenegro's Adriatic coast using optical and Raman microscopy, detecting microplastics in all samples along with elevated concentrations of trace metals, providing the first combined MPs and inorganic contaminant data for this coastline.
Impacts of Fishing Vessels on the Heavy Metal Contamination in Sediments: A Case Study of Qianzhen Fishing Port in Southern Taiwan
Researchers assessed heavy metal contamination in sediments from Qianzhen Fishing Port in southern Taiwan, finding elevated levels from vessel maintenance and wastewater discharges. While focused on heavy metals rather than microplastics specifically, the study is relevant to understanding the combined pollution burdens in port environments where plastic and chemical contamination co-occur.
Effects of trace metals and microplastics on the gene expression of antioxidant and detoxification genes in Mytilus galloprovincialis from estuaries
Researchers measured microplastic contamination and trace metal concentrations alongside antioxidant and detoxification gene expression in wild mussels from three estuaries in the Asturias region of Spain. Significant differences in both pollutant levels and gene expression were found between clean and polluted sites, though post-mining estuaries showed signs of recovery.
Quantification of Microplastics in North-Western Mediterranean Harbors: Seasonality and Biofilm-Related Metallic Contaminants
Scientists measured microplastic concentrations in three Mediterranean harbors across seasons, finding higher levels in summer (coinciding with peak boating activity) and detecting heavy metals associated with plastic biofilms. Harbors are identified as significant hotspots for microplastic pollution that spreads into surrounding coastal waters.
Microplastic contamination in marine mussels from the Atlantic coast of North Portugal and human risk of microplastic intake through mussel consumption
Researchers analyzed wild mussels from Portugal's Atlantic coast and found microplastics in all samples, with an average of about 1.6 particles per gram of mussel tissue. Based on typical Portuguese seafood consumption patterns, the estimated annual human intake of microplastics from mussels alone was calculated, highlighting that regular shellfish consumers face meaningful microplastic exposure through their diet.
Microplastics 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.
