Microplastics monitoring in mussels and water from the port of sines, portugal
AI summary Read the abstract
Researchers quantified microplastic pollution in mussels and seawater from the Port of Sines, the main Atlantic-facing port in Portugal, assessing contamination levels in a heavily used industrial maritime setting. Microplastics were detected in both water and mussel tissue, with port activity identified as a localized source of elevated contamination.
Seaports are particularly susceptible to microplastic (MP) pollution through a series of human activities occurring in these areas. Thus, monitoring the biological communities and water is important to assess the impacts of MP pollution. In this work, we quantify extent of MP pollution in the Port of Sines, the main port in the Iberian-Atlantic coast, capable of receiving any type of vessel, which makes this port a potential source and sink of contaminants, including MP. Adjacent to this port, there are moderate to very exposed marine areas with regional and national importance for fisheries, tourism, and conservation. The present study reports the quantity, shape, colour and polymer type of MP in whole soft tissues of mussels (Mytilus spp.), and seawater samples collected in 2022 and 2023. Here, a baseline evaluation of MP concentration at the seawater surface and column was conducted in triplicate with a manta and bongo nets (150 μm mesh), respectively for horizontal and vertical tows, in a total of six sampling sites outside and inside the port. Mussels and water were collected in the same sampling sites. Samples were digested with 10This work will contribute with baseline data regarding MP pollution and accumulation in biota and water of the Port of Sines and adjacent coastal areas, providing a solid background for future research to assess effects of MP in the marine environment and their potential hazards, helping policymakers to make knowledge-based decisions on plastic litter management.

Microplastics monitoring in mussels and water from the port of sines, portugal
AI summary Read the abstract
Researchers monitored microplastic contamination in mussels and seawater at the Port of Sines, Portugal's main Atlantic commercial port, over time to assess how port activities influence local plastic pollution levels. Mussel tissue and water samples both contained measurable microplastics, with contamination patterns reflecting shipping, maintenance, and industrial activities at the port.
Are mussels accumulating trace metals and microplastics in port facilities?
AI summary Read the abstract
Mediterranean mussels deployed at port facilities in Spain were analyzed for trace metals and microplastics, finding elevated contamination compared to reference sites, with both contaminant types reflecting local shipping and maintenance activities as pollution sources.
Microplastics in Marine and Estuarine Species From the Coast of Portugal
AI summary Read the abstract
Researchers surveyed microplastic contamination in five marine and estuarine species collected from the coast of Portugal, including mussels, clams, and polychaetes. They found microplastics in all species examined, with fibers being the most common type, and noted differences in contamination levels between sampling sites. The study contributes baseline data on microplastic pollution in commercially relevant Portuguese seafood species.
Microplastic contamination in marine mussels from the Atlantic coast of North Portugal and human risk of microplastic intake through mussel consumption
AI summary Read the abstract
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.
Microplastic in bivalves of an urbanized Brazilian estuary: Human modification, population density and vegetation influence
AI summary Read the abstract
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.
