ClearMarine litter and microplastic pollution on mangrove soils of the Ciénaga Grande de Santa Marta, Colombian Caribbean
Researchers assessed marine litter and microplastic contamination in mangrove soils of Colombia's largest coastal lagoon system for the first time. They found significantly higher litter concentrations near populated areas, with plastics comprising up to 96% of all debris, and microplastic levels varying widely across sampling sites. The study highlights the link between inadequate waste management in coastal communities and microplastic accumulation in ecologically important mangrove habitats.
Microplastics and plastisphere at surface waters in the Southwestern Caribbean sea
Researchers surveyed microplastic pollution at the surface waters of two marine-coastal areas in the Southwestern Caribbean Sea across wet and dry seasons. The study found higher microplastic concentrations during the rainy season, likely due to increased runoff carrying land-based plastic waste into the ocean. Evidence indicates that seasonal weather patterns and local land use significantly influence microplastic distribution in coastal marine environments.
Campaña de comunicación sobre consumo responsable de productos de la industria de la moda: percepción del mensaje e influencia en el comportamiento de millennials en Colombia
This study examined how a responsible consumption communication campaign targeting the fashion industry was perceived by Colombian millennials, finding that message framing and delivery channel significantly influenced awareness and self-reported behavioral intentions regarding sustainable clothing choices.
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.
Microplastics of surface waters of Colombian Caribbean
This is a duplicate entry for the Colombian Caribbean surface water microplastics study (same as ID 1858), covering microplastic characterization and plastisphere microbial communities in two river-influenced Caribbean sectors during dry and rainy seasons. Duplicate entry; the study provides important baseline contamination data and microbial ecology context for a poorly studied tropical region.
Biomaterials for change
Researchers investigated natural fiber composites (NFCs) derived from corn crop waste and fique plant fibers as biodegradable substitutes for foamed plastics such as Styrofoam, mentoring five cohorts of undergraduate industrial design students in capstone projects from 2018 to 2021. The program produced a family of six new NFCs and nearly a dozen product applications targeting the construction, packaging, and automotive industries.
Photocatalytic Degradation of Dielectric Mineral Oil with PCBs Content Coupled with Algae Treatment
This study tested photocatalytic oxidation combined with microorganism treatment to degrade insulating oil contaminated with polychlorinated biphenyls (PCBs), a persistent toxic pollutant. The combined approach improved degradation efficiency compared to either method used alone.
Las grandes manchas de plásticos en los océanos
This Spanish-language paper describes the formation and characteristics of ocean plastic accumulation zones, known as garbage patches, where ocean current convergence concentrates floating plastic debris. It reviews how these large plastic accumulations form and their environmental significance.
Microplastics of marine sediments of the Colombian Caribbean
This study quantified and characterized microplastics in marine sediments from two sectors of the Colombian Caribbean influenced by the Magdalena and Sinú rivers. Microplastics were found at all sampling sites, providing baseline data for this understudied region.
