Microlitter Distribution on Sandy Beaches of the Neva Bay of the Gulf of Finland (Baltic Sea) in 2018–2022
AI summary Read the abstract
Researchers assessed the distribution and abundance of microlitter on sandy beaches of the Neva Bay in the Baltic Sea across 2018–2022, mapping spatial and temporal patterns driven by St. Petersburg's urban runoff. The findings reveal how densely populated coastal cities act as persistent point sources of microplastic pollution into semi-enclosed seas with limited dilution capacity.
The city of St. Petersburg plays a significant role in the environmental state of the Neva Bay, including its contamination with wastes and marine litter. The goal of this work is to assess the distribution of microlitter on the coasts of the open part of the Gulf of...

Marine Litter in the Russian Gulf of Finland and South-East Baltic: Application of Different Methods of Beach Sand Sampling
AI summary Read the abstract
Surveys of Baltic Sea beaches and sediments across Russian coastal zones from 2016 to 2020 documented widespread marine litter including microplastics, with methodology comparisons revealing how sampling technique affects detection rates. Standardizing beach sampling protocols is essential for generating comparable data that can track pollution trends and inform cleanup priorities across international coastlines.
Data on the Microplastics Content in the Bottom Sediments of the Gulf of Finland and Southeastern Part of the Baltic Sea According to the Data of 39th Cruise of the R/v “Akademik Nikolai Strakhov”
AI summary Read the abstract
Researchers analyzed microplastic concentrations in bottom sediments of the Gulf of Finland and Baltic Sea, finding a patchy and variable distribution pattern that complicates efforts to predict where these particles accumulate in important fishery and ecosystem zones.
Microplastics Beach Pollution: Composition, Quantification and Distribution on the Southern Coast of Brazil
AI summary Read the abstract
Researchers quantified microplastic pollution on a southern Brazilian beach, finding an average of 650 MPs/kg of sediment with highest concentrations near the Mampituba River mouth, dominated by polyethylene, polypropylene, and polyamide particles in the 50–100 µm range. The findings confirm that riverine transport is a major pathway delivering microplastics to coastlines, underscoring the need for upstream source control to protect coastal ecosystems.
Toward a Method of Assessing Microplastic Accumulation in Beach Sand Deposits
AI summary Read the abstract
Researchers tested four saline density separation solutions to develop a low-cost method for extracting and quantifying microplastics from beach sand, achieving recovery rates of 61–78% for coarse particles across six plastic types. Standardizing affordable extraction methods is a critical step toward generating comparable microplastic concentration data across global beach environments.
Evaluation of Microplastics in Beach Sands on Isle of Man
AI summary Read the abstract
Researchers evaluated microplastic contamination in beach sands on the Isle of Man, finding plastic particles capable of releasing harmful chemicals into coastal environments. Beach contamination is significant because it indicates ongoing fragmentation of larger plastics and potential exposure pathways for coastal communities and marine life.
