Researchers surveyed plastic litter pollution on 43 beaches along Colombia's Caribbean and Pacific coasts, documenting the types and quantities present and calling for locally adapted management strategies.
Citizen Science for Assessment of Microplastics on Beaches: A Case Study in Mexico
Researchers used a citizen science approach involving 26 volunteers to assess microplastic abundance and type on Mexican beaches, providing broad geographic coverage at lower cost than traditional monitoring. Participants used standardized materials and training to collect and identify microplastics, generating a representative database that also raised public awareness of coastal plastic pollution.
The sampling and analysis of coastal microplastic and mesoplastic: Development of a citizen science approach
This study designed, developed, and tested a citizen science approach to microplastic and mesoplastic data collection on coastal beaches to address scale and coverage limitations of traditional research methods. Results showed non-expert participants could collect comparable data to researchers, expanding monitoring capacity across undersampled coastlines.
Using citizen science to understand floating plastic debris distribution and abundance: A case study from the North Cornish coast (United Kingdom).
This citizen science study used a standardized methodology to monitor floating plastic debris off the Cornish coast of the UK, finding microplastic concentrations comparable to or higher than other European coastal regions. The study demonstrates that citizen science can generate useful, standardized data on plastic pollution in coastal waters.
Evaluación de los residuos sólidos encontrados en playas de la Costa Verde, Lima, Perú durante el invierno de 2021
A survey of solid waste on four beaches of Lima, Peru during winter 2021 documented the types and quantities of litter present. The findings reveal the scale of anthropogenic waste on these urban beaches and inform local waste management strategies.
Microplásticos en tres playas del corredor turístico del norte, Piura, Perú
Researchers estimated the abundance, characteristics, and types of microplastics on three beaches along the northern tourist corridor of Piura, Peru, characterising the size, colour, and polymer types of particles found in beach sediments to assess contamination levels in this coastal region.
Microplastic distribution and composition on two Galápagos island beaches, Ecuador: Verifying the use of citizen science derived data in long-term monitoring
Researchers validated a citizen science methodology for monitoring visible microplastic contamination on Galapagos island beaches using standardized quadrat sampling, comparing citizen-generated data with expert surveys over multiple years. The approach was found to produce reliable data for long-term monitoring while reducing costs, supporting its use in logistically challenging remote locations.
First approach to microplastics occurrence in sandy beaches in the province of Islay (Arequipa), southern Peru
Researchers conducted the first assessment of microplastic occurrence on five sandy beaches in the province of Islay in southern Peru, sampling to 5 cm depth and finding 304 particles total with average densities of 1–4 particles/m2. Beaches adjacent to the Tambo River estuary showed the highest microplastic concentrations, suggesting river transport as a significant delivery pathway to coastal environments.
Ocean-based sources of plastic pollution: An overview of the main marine activities in the Peruvian EEZ.
This study used material flow analysis to quantify the plastic waste entering the ocean from Peruvian fishing, shipping, and aquaculture activities, finding the fishing industry as the largest marine-based source. The results highlight the importance of ocean-based sources of plastic pollution alongside the better-studied land-based pathways.
Microplastics on Santos Beach: Sources of Pollution, Waste Characteristics and Possible Collection Solutions
This Brazilian study mapped and characterized microplastic contamination on Santos beach near submarine sewage outfalls and storm drains, finding plastic pollution hotspots linked to coastal discharge infrastructure. The authors estimated that ~60 tons of solid waste enter the sea daily in the region and identified possible collection solutions.
Tracking microplastics and the associated ecological risk in the southwestern Pacific Ocean
Researchers assessed microplastic abundance and composition along an approximately 1,000 km oceanographic transect of the southwestern Pacific coast of Chile, sampling at six river mouths and characterizing the ecological risk associated with plastic pollution entering coastal marine environments.
Occurrence and Distribution of Microplastics on the Beaches of Limón on the Southern Caribbean Coast of Costa Rica
Microplastic occurrence and distribution were characterized across 70 km of Caribbean coastline beaches in Limón, Costa Rica, spanning protected natural areas, agricultural zones, and urban and port areas. MPs were present at all sites, with higher concentrations near urban and port areas, highlighting land-based human activity as the primary local source.
INVEMAR produce scientific information with the implementation of REMARCO protocols for monitoring microplastics in Colombia
This study describes the implementation of REMARCO standardized protocols by INVEMAR to monitor microplastics along Colombia's Caribbean and Pacific coastlines, addressing a context where approximately 65% of plastic waste is disposed of in open dumps or natural water bodies, and generating baseline scientific data on microplastic accumulation in coastal and marine ecosystems.
Abundance and distribution of microplastics on sandy beaches of Lima, Peru
This survey assessed microplastic pollution on four popular sandy beaches of Lima, Peru, sampling both intertidal and supralittoral zones. Microplastics were found at all sites, with fragments being the most common morphology, and concentrations varying across beach zones and locations.
