Abundance, composition, and distribution of microplastics in intertidal sediment and soft tissues of four species of Bivalvia from Southeast Brazilian urban beaches

Researchers found 100% microplastic contamination in intertidal sediments and four bivalve species from urbanized Brazilian beaches, identifying polypropylene, polyethylene, and PET polymers in organisms commonly consumed by humans.

Can microplastic pollution be affected by beach nourishment? Assessment in intertidal sediment and bivalves

Researchers investigated whether beach nourishment, a common coastal erosion mitigation technique, affects microplastic pollution in sediments and bivalves along two beaches in southeastern Brazil. They found a 171% increase in total microplastic counts after the nourishment process, indicating that dredged material used to replenish beaches can dramatically increase local microplastic contamination.

Saúde ambiental de praias arenosas: distribuição e níveis de contaminação na biodiversidade bêntica

This Portuguese-language study assessed environmental health of sandy beaches in Brazil, measuring microplastic distribution, contamination indices, and bioindicator organisms to evaluate ecological status and identify pollution sources along the coastline.

Dispersão de microplásticos em águas superficiais e sedimentos de fundo da plataforma continental de Fortaleza

Researchers examined the distribution and characteristics of microplastics in surface waters and bottom sediments of the continental shelf off Fortaleza, Brazil, characterizing MP abundance and morphology to assess contamination levels in this South American marine environment.

Contaminação Por Microplásticos Em Praias Arenosas No Brasil: Uma Revisão Sistemática

This review systematically examines microplastic contamination studies on sandy beaches across Brazil, covering publications from the first Brazilian study in 2009 onward and identifying that sediment (76% of studies), water (12%), and biota (12%) are the primary compartments investigated. The review finds tourism, fishing, and river discharge as the main microplastic sources, and identifies significant methodological gaps that limit cross-study comparisons.

A year-long monitorization of microplastic pollution in a bivalve aquaculture located at a coastal lagoon from Portugal

Researchers conducted a year-long quarterly monitoring study of microplastic contamination in Crassostrea gigas (diploid and triploid) and Ruditapes philippinarum bivalves from a Portuguese coastal lagoon aquaculture, alongside monthly water and sediment sampling. Microplastics were detected in every environmental matrix and in all tissue types examined, including muscle, digestive gland, gills, and visceral mass, demonstrating persistent contamination throughout the aquaculture system.

The distribution and ecological effects of microplastics in an estuarine ecosystem

Researchers surveyed 22 intertidal sites and found that microplastic abundance, size, and diversity correlated with benthic microalgal communities and sediment biostabilization properties in an estuarine ecosystem.

Contaminação e toxicidade de microplásticos em uma área de proteção marinha costeira

This Brazilian study assessed microplastic contamination and toxicity in a coastal marine protected area, finding that sandy beaches accumulate plastic particles carried in by the ocean. The research highlights that even protected coastal zones are not immune to microplastic pollution, which can be ingested by marine wildlife and enter food webs.

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.
