ClearRethinking the Environmental Quality of Brazilian Beaches: The Incidence of Microplastics as Indicator for Sea Water and Sand Quality
This paper proposes using microplastic levels in beach sand and seawater as indicators of beach environmental quality, arguing that current assessments in Brazil focus too narrowly on microbial contamination. The authors present evidence that microplastic contamination poses health risks to swimmers and coastal communities that should be incorporated into beach quality standards.
Textural characteristics and abundance of microplastics in Tecolutla beach sediments, Gulf of Mexico

Researchers assessed microplastic contamination in beach sands, surface waters, and sediment traps in the tourist city of Mazatlan, Mexico, finding higher concentrations during the rainy season and in urban areas, with polyethylene and polypropylene fragments being the most abundant types.
Evaluating Microplastic Pollution in Beach Sands from the Mexican Pacific Coast: Insights from a Standardized Monitoring Approach
Researchers implemented a standardized REMARCO/IAEA monitoring protocol at two tourist beaches and a coastal lagoon in Mazatlan, Mexico, collecting 124 beach sand samples between June 2020 and July 2021 to assess microplastic pollution (1-5 mm) and temporal variability, identifying fragments and foam as dominant types and synthetic polymers including polyethylene and polypropylene as primary constituents via ATR-FTIR analysis.
Dataset of quantification and classification of microplastics in Mexican sandy beaches
This dataset presents the first national survey of microplastic contamination on 35 Mexican beaches across five coastal regions. Microplastics were found at all beaches, with fragments and pellets being the most common types, providing baseline data for monitoring plastic pollution along Mexico's coasts.
Pollution level of microplastics in sand beaches of four locations in the coast of El Salvador, Central America
Researchers assessed microplastic pollution levels in sandy beaches at four coastal locations in El Salvador, Central America, characterizing the concentration, spatial distribution, physical and chemical properties, and potential sources of microplastics and applying the Nemerow pollution index to categorize overall contamination levels at each site.
Microplastics on sandy beaches of the Baja California Peninsula, Mexico
Microplastics were found on all 21 sandy beach sites surveyed along the Baja California Peninsula in Mexico, with pellets and fragments as the dominant types and higher concentrations near urban areas. The study provides baseline data on microplastic contamination along a lengthy stretch of Mexican Pacific coastline largely lacking previous environmental monitoring.
Impact of microplastic pollution on coastal ecosystems using comprehensive beach quality indices
This study applied three beach quality indices to assess microplastic pollution in Chinese beach sediments, finding that all sampled beaches rated "very high" pollution and "bad" environmental status. The work provides a standardized framework for quantifying microplastic impact on beach environments, which is useful for guiding cleanup priorities and policy decisions.
Microplastics in brazilian marine environments: a study on beaches in São Francisco do Sul - SC
Beach surveys along São Francisco do Sul in southern Brazil confirmed widespread microplastic presence in coastal sediments, with polymer composition reflecting regional plastic waste streams. The study adds to the body of evidence that Brazilian coastlines are significantly contaminated and calls for national monitoring standards to track and manage the problem.
Microplastics on Santos Beach: Sources of Pollution, Waste Characteristics and Possible Collection Solutions
Researchers characterized microplastics collected from three zones of Santos beach in Brazil, finding contamination dominated by fragments and films near sewage outfalls. The study highlights inadequate waste management as the primary driver of beach microplastic accumulation and assessed feasibility of mechanical collection interventions.
Evaluation of Water Quality and the Potential Ecological and Health Risk in the Cajititlán Lagoon
Not relevant to microplastics — this ecological study tracks physicochemical water quality parameters and heavy metal concentrations in a Mexican lagoon over 14 years to assess ecosystem health and human health risk, with no focus on plastic pollution.
Microplastics in surface waters surrounding a touristic beach at the Gulf of California, Mexico
Researchers measured microplastic concentrations in surface waters around a popular tourist beach in Mexico's Gulf of California, finding that particle levels roughly doubled after spring vacation compared to before. Fibers were the most abundant type, and concentrations were highest closest to tourist activity. The results directly link human recreational activity to spikes in coastal microplastic pollution, underscoring the role of tourism in contaminating marine environments.
Mesoplastics and large microplastics along a use gradient on the Uruguay Atlantic coast: Types, sources, fates, and chemical loads
Plastic debris was found on Uruguayan beaches along a gradient of tourist use, with polypropylene and polyethylene being the most common polymers and various toxic chemicals detected on the particles. The study shows that recreational beach use is linked to higher plastic contamination in coastal environments.
Microplastics and Geotechnical Characteristics of the Sand at Praia Do Futuro, Ceará, Brazil
A survey of microplastic concentrations in beach sediments at Praia do Futuro, Brazil found levels that exceeded those in other Brazilian studies but were lower than many international benchmarks, with no significant difference between tourist-heavy and quieter zones. The study also characterized the sand's physical properties, providing baseline data for future monitoring in a region where coastal microplastic research has been limited.
Anthropogenic Litter on Beaches With Different Levels of Development and Use: A Snapshot of a Coast in Pernambuco (Brazil)
Beach litter was surveyed at nine sites in northeastern Brazil, finding plastic dominated at all beach types but with differences in litter composition linked to local activities. Characterizing litter sources at specific beaches is essential for targeted waste reduction policies.

Researchers assessed microplastic pollution in sea turtle nesting beaches in Veracruz, Mexico, documenting contamination levels and types that could alter sand properties and negatively affect turtle egg incubation conditions.
(Micro)plastics: A possible criterion for beach certification with a focus on the Blue Flag Award
This paper argues that microplastic pollution should be incorporated as a criterion in beach quality certification programs like the Blue Flag Award. Including plastics monitoring would better reflect actual environmental health and encourage cleaner beach management.
