ClearPersistent organic pollutants carried on plastic resin pellets from two beaches in China
Researchers found that plastic resin pellets collected from two Chinese beaches contained significant concentrations of PAHs, PCBs, organochlorine pesticides, and other persistent organic pollutants sorbed to their surfaces. The findings confirm that plastic pellets act as vectors for long-range transport of multiple classes of hydrophobic chemical contaminants in marine environments.
Association between PAH and plastic fragments on Brazilian coast beaches: a baseline assessment
Researchers conducted a baseline assessment of the association between polycyclic aromatic hydrocarbons (PAHs) and plastic fragments collected from beaches along the Brazilian coast, characterising how microplastics act as adsorption surfaces for these organic pollutants. The study found co-occurrence of PAHs and plastic fragments at sampled sites, establishing contamination baselines and informing understanding of the plastic-pollutant vector pathway.
Quantification of PAHs, PCBs and Pesticides adsorbed by plastic waste in the Togolese marine environment
Researchers analyzed plastic waste collected along the Togolese coast and found it contaminated with PAHs and PCBs, demonstrating that marine plastics act as vectors for toxic organic pollutants. This adsorption of harmful chemicals onto plastic surfaces poses risks to marine organisms and potentially to humans who consume seafood.
Contaminación por vertidos de aguas residuales: Una revisión de las interacciones microorganismos–microplásticos y sus posibles riesgos ambientales en aguas costeras colombianas
This review analyzes how wastewater discharges into Colombian coastal waters introduce both microplastics and pathogenic microorganisms, examining the environmental risks of microorganism-microplastic interactions and their implications for biodiversity and human health.
Plastic litter pollution along sandy beaches in the Caribbean and Pacific coast of Colombia
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.
Microplastics and associated polycyclic aromatic hydrocarbons in surface water and sediment of the Bay of Bengal coastal area, India: sources, pathway and ecological risk
Researchers surveyed microplastic contamination in surface water and sediment along two Bay of Bengal coastal beaches in India and found microplastics present at both sites. They also detected polycyclic aromatic hydrocarbons, a group of harmful chemicals, adsorbed onto the microplastic surfaces at concentrations that varied by particle shape. The study highlights that microplastics in coastal waters act as carriers for toxic organic pollutants, potentially increasing ecological risks in the marine environment.
Plastic pollution in marine ecosystems: spatiotemporal assessment in beach sediments of protected coastal areas
Researchers conducted a spatiotemporal assessment of plastic pollution including microplastics in beach sediments across 13 beaches in marine protected areas in Colombia and the Canary Islands, Spain, evaluating plastic debris under varying environmental conditions in ecologically sensitive coastal zones.
Trace elements in microplastics in Cartagena: A hotspot for plastic pollution at the Caribbean
Microplastics collected from beaches in Cartagena, Colombia were found to carry trace metals including mercury, lead, and arsenic at concentrations of potential concern. The findings add to evidence that microplastics can act as vectors for heavy metal contamination in coastal environments.
Microplastics pollution on Colombian Central Caribbean beaches
Researchers conducted a baseline survey of microplastic contamination on Colombia's Central Caribbean Coast beaches, documenting MP types, sizes, and polymer compositions for the first time in that region and finding primarily secondary microplastics from fragmented larger debris.
Microplastics of surface waters of Colombian Caribbean
Researchers collected and characterized microplastics from the surface waters of two Colombian Caribbean sectors influenced by major rivers, sampling across dry and rainy seasons and also analyzing the microbial communities living on the plastic surfaces. The study provides baseline pollution data for a region where microplastic research has been minimal, while the metagenomic analysis of plastisphere microbes adds ecological context. Understanding which microbes colonize plastic in tropical Caribbean waters is relevant to assessing whether those particles serve as vectors for harmful or antibiotic-resistant bacteria.
The sorption of persistent organic pollutants in microplastics from the coastal environment
Researchers sampled microplastic pellets from six beaches around Taiwan and measured concentrations of persistent organic pollutants (dioxins, PCBs, PBDEs) on their surfaces, finding that pellets accumulated significant POPs loads with concentrations that correlated with proximity to industrial areas.
Organic pollutants in microplastics from two beaches of the Portuguese coast
Microplastic samples from two Portuguese beaches were analyzed for persistent organic pollutants including PAHs and PCBs, with sorbed concentrations varying by plastic color and degree of weathering. The study confirms that beached microplastics carry toxic organic chemicals and that older, more weathered particles tend to carry higher contaminant loads.
Los microplásticos, una amenaza desconocida para los ecosistemas marinos de Colombia: perspectivas y desafíos a enfrentar
This review examines microplastic contamination in Colombian marine ecosystems, highlighting the serious but poorly understood threat these particles pose to marine biota, ecosystem balance, and human health. The authors identify key research gaps and challenges specific to Colombia's coastal and oceanic environments.
Microplastic-sorbed persistent organic pollutants in coastal Mediterranean Sea areas of Tunisia
Researchers analyzed microplastics collected from four Tunisian Mediterranean beaches, finding they contained sorbed persistent organic pollutants including polychlorinated biphenyls and organochlorine pesticides, highlighting microplastics as vectors for toxic chemicals.
Voyaging of halogenated polycyclic aromatic hydrocarbons, an emerging group of pollutants, on micro-mesoplastics in the marine environment.
Researchers detected 61 of 75 target halogenated polycyclic aromatic hydrocarbons in micro-mesoplastics collected from coastal environments in Sri Lanka and Japan, finding that plastic surfaces accumulate these emerging pollutants at concentrations far exceeding surrounding sediments and that chlorinated PAHs dominated over brominated forms at both sites.
Contaminación por microplásticos en las playas de Crucita, Ecuador: abundancia y composición de polímeros
Researchers quantified microplastic abundance and identified polymer types in sand samples from three beaches in Crucita, Ecuador, characterizing the contamination profile of this South American coastal environment and contributing to regional baseline data on MP pollution.

Researchers analyzed marine debris data collected during expeditions to the Seaflower Biosphere Reserve in Colombia, examining pollution sources, marine health implications, and public policy gaps. The study identifies plastic as the dominant debris type and discusses the disconnect between observed marine pollution and existing regulatory frameworks.

This study analyzed the current state of marine debris in Costa Rica, documenting plastic waste distribution along Pacific and Caribbean coasts and identifying key sources of marine pollution threatening coastal ecosystems.
Determination of organochlorine pesticides adsorbed on plastic pellets
Researchers analyzed organochlorine pesticides adsorbed onto plastic pellets found in coastal environments, contributing to understanding of how plastic debris accumulates and concentrates toxic chemicals. Plastic pellets, a type of microplastic, can act as carriers bringing persistent organic pollutants into marine food webs.
Plastiglomerates from uncontrolled burning of plastic waste on Indonesian beaches contain high contents of organic pollutants
Researchers examined plastiglomerates — rocks fused with melted plastic — from Indonesian beaches where plastic waste is burned openly, finding high concentrations of toxic polycyclic aromatic hydrocarbons (PAHs) and phthalates in the samples. The burning process makes plastics more brittle and prone to breaking into microplastics, while also creating new mobile pollution forms that can carry chemical contaminants into nearby coral reefs and coastal habitats.
