Microplastic in two South Carolina Estuaries: Occurrence, distribution, and composition
Microplastics were found throughout intertidal sediments of two developed estuaries in South Carolina, with higher concentrations near urban centers and sewage outfalls. The study provides baseline contamination data for two important US Atlantic coast estuaries and confirms that nearshore estuarine sediments in the southeastern US accumulate significant microplastic pollution.

Microplastics were found in beach sediments along three sites on the northern French coast, with the most contaminated site near an urban-industrial area. Fragments and films dominated, reflecting local land-based and maritime sources of plastic pollution.
Characterization of environmental microplastics present in unconsolidated sediments in coastal waters of 9 beaches on shoreline of Rio de Janeiro, Brazil
Researchers characterized environmental microplastics in unconsolidated sediments from nine beaches along the southern coast of Brazil, identifying particle abundance, morphology, color, and polymer composition. The study documented widespread microplastic contamination at all sampled coastal sites, with fragments and fibers being the dominant morphological types found in the sediment samples.
Microplastics in mangrove and beach sediments on southeast Florida barrier islands
Researchers quantified and characterized microplastic abundance, distribution, and variation in estuarine mangrove and beach sediments across southeast Florida barrier islands. The study aimed to improve understanding of microplastic hazards in these coastal ecosystems to support conservation efforts for mangrove and beach environments.
Assessment of micro and macroplastics along the west coast of India: Abundance, distribution, polymer type and toxicity.
This study assessed the abundance and types of micro- and macroplastics on ten beaches along India's west coast, finding plastic in all locations with fragments being the most common form. Polymer analysis revealed polypropylene, polyethylene, and polystyrene as the dominant types, and toxicity testing indicated the plastic-contaminated sediments posed ecological risks.
Distribution and characterization of microplastics in marine sediments from coastal and offshore in South Korea
Researchers conducted an intensive survey of microplastic levels and distribution in marine sediments from coastal areas, recognizing the seafloor as the ultimate repository for plastic particles. Microplastic concentrations in sediments were highest near urban and industrial coastlines, with fibers and fragments as the most common types.
Occurrence and distribution of microplastics at selected coastal sites along the southeastern United States
Researchers quantified microplastics in beach sand at 18 U.S. National Park beaches in the Southeast and built a model to predict how ocean currents transport plastic debris. The study provides a baseline for plastic contamination even in protected coastal areas and highlights how distant pollution sources can affect remote beaches.
Occurrence and distribution of microplastics in marine sediments along the Belgian coast
Researchers surveyed marine sediments along the Belgian coast and found microplastics distributed across all sampled sites, documenting their occurrence and characteristics in this heavily trafficked North Sea coastal environment.
Microparticles of anthropogenic origin (microplastics and microfibers) in sandy sediments: A case study from calabria, italy
Researchers characterized microplastics and microfibers in sandy beach sediments from Calabria, Italy, finding both types of anthropogenic microparticles widespread across sampling sites. Microfibers were particularly abundant despite receiving far less monitoring attention than microplastic fragments, calling for their inclusion in standard beach pollution assessments.
Microplásticos En Tres Playas Del Corredor Turístico Del Norte, Piura, Perú
Researchers sampled sediments from three beach zones along northern Peru's tourist corridor in February 2024 and characterized microplastic abundance, morphology, and polymer types using FTIR analysis. Microplastics were detected across all sampling zones, with fragments and fibers dominating and polyethylene as the most common polymer type.
Characterization of microplastic and mesoplastic debris in sediments from Kamilo Beach and Kahuku Beach, Hawai'i
Researchers characterized nearly 49,000 large microplastic and mesoplastic particles (0.5–8 mm) hand-picked from two Hawaiian beaches, finding white/transparent fragments were most abundant (72%) and that polyethylene and polypropylene dominated polymer types as confirmed by Raman spectroscopy.

Presence, Spatial Distribution, and Characteristics of Microplastics in Beach Sediments Along the Northwestern Moroccan Mediterranean Coast
Researchers surveyed fourteen beaches along the northwestern Moroccan Mediterranean coast and found microplastics in every sediment sample, averaging about 59 particles per kilogram of dry sand. Fibers were the dominant shape at nearly 78%, with tourism, fishing, and wastewater discharges identified as the most likely pollution sources. The findings indicate moderate but widespread microplastic contamination along this coastline.
