A PRISMA-based review of microplastic research in Mexico documented growing contamination across marine, freshwater, and terrestrial environments, characterized the dominant polymer types and particle shapes, and identified major knowledge gaps needing attention in the Mexican context.
Microplastic contamination and fluxes in a touristic area at the SE Gulf of California
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.
Seasonal evidences of microplastics in environmental matrices of a tourist dominated urban estuary in Gulf of Mexico, Mexico
Spatial and seasonal variations in microplastic abundance were examined across water, sediments, and commercial fish in a tourist-impacted estuary in the Gulf of Mexico, finding peak contamination during dry season and at sites closest to urban and fishing activities.
Spatio and temporal dynamics of microplastic fluxes within the watercourses of a peri-urban watershed
Researchers tracked the spatiotemporal dynamics of microplastic fluxes within a river catchment over time, linking plastic transport patterns to land use activities. The study found that land use type is a key driver of when and how much microplastic enters and moves through watercourses.
Impact of land cover on microplastics accumulation in freshwater sediments
Researchers tracked microplastic accumulation in freshwater sediments across sites with different land cover types, examining temporal trends to understand how land use affects plastic discharge into waterways. Land cover type was a significant predictor of sediment microplastic concentration, with urbanized and agricultural catchments showing higher accumulation.
Microplastics in groundwater of two rural communities in Mexico
Researchers detected microplastics in drinking water from ten rural wells in two Mexican communities, finding diverse polymer types and morphologies at concentrations that suggest widespread groundwater MP contamination even in areas distant from major urban pollution sources.
Occurrence and amount of microplastic ingested by fishes in watersheds of the Gulf of Mexico
Researchers quantified microplastic ingestion by fishes across several freshwater and estuarine watersheds of the Gulf of Mexico. The study documented widespread microplastic occurrence in fish from these environments, contributing important data about freshwater contamination at a time when most research had focused on marine ecosystems.
First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
Researchers conducted the first investigation of microplastic pollution in groundwater in Latin America, analyzing six capped boreholes in a coastal aquifer in northwest Mexico for microplastic abundance, concentration, and characteristics. The study detected microplastics in groundwater samples, establishing baseline contamination data for this understudied environmental compartment and raising concerns about drinking water quality in the region.
Occurrence of microplastics in a coastal aquifer in Northwest Mexico
Researchers analyzed 18 groundwater samples from six boreholes at three depths in the Laguna Agua Grande coastal aquifer in Northwest Mexico, finding 221 microplastic particles at concentrations averaging 12.3 particles/L. Four polymers were identified by FTIR, with isotactic polypropylene dominating at 64%, and agriculture activities and septic tank outflows identified as likely sources with three proposed transport pathways into the aquifer.
Spatiotemporal variation in microplastic contamination along a subtropical reservoir shoreline
Researchers tracked microplastic contamination along the shoreline of a subtropical reservoir over two years and found that microplastic abundance was higher near urban areas and varied with season, with storm-related inputs creating significant temporal spikes.
Occurrence of Microplastics in Kemena River and Niah River of Sarawak, Malaysia
Researchers investigated microplastic occurrence in water and riverbed sediments of the Kemena and Niah Rivers in Sarawak, Malaysia, finding that urbanization along these rivers correlates with higher microplastic concentrations in freshwater environments.
Spatial and temporal distribution of microplastics in water and sediments of a freshwater system (Antuã River, Portugal)

Spatio and temporal dynamics of microplastic fluxes within the watercourses of a peri-urban watershed
Researchers tracked spatial and temporal microplastic flux dynamics in the watercourses of a small peri-urban catchment, examining how different land use types within the watershed contribute to plastic loading in connected streams. Land use strongly influenced microplastic flux, with urbanized and agricultural sub-catchments contributing proportionally more plastic particles to the waterway network.

Researchers reviewed 38 indexed studies on microplastic contamination in aquatic and terrestrial ecosystems across Mexico published between 2015 and 2024, finding research distributed across soils/sediments (34%), fauna (34%), water (24%), flora (5%), and air (3%). The review highlights substantial methodological variability across studies and calls for standardised protocols to improve comparability of Mexican microplastics research.

Researchers surveyed microplastic contamination in surface water, sediments, and wastewater treatment plant effluents in Todos Santos Bay, Mexico, detecting microplastics in all matrices with fragments and fibers as the dominant morphologies and polypropylene and polyethylene among the identified polymers. Wastewater treatment plant effluents were identified as a key source, contributing fibers to the bay, while surface currents and sediment grain size governed spatial distribution.
