Determinación de microplásticos en sedimento del supra-, meso- e infra-litoral costero del departamento del Atlántico
AI summary Read the abstract
Researchers investigated microplastic contamination in coastal sediments across supralittoral, mesolittoral, and infralittoral zones in the Atlántico department of Colombia, characterizing particles by size, shape, and polymer composition to assess long-term environmental risk, with the study aimed at providing baseline data for microplastic management in this understudied Caribbean region.
En este estudio se investiga la contaminación por microplásticos en los ecosistemas costeros del departamento del Atlántico, Colombia. Se reconoce la falta de información sobre este contaminante emergente en la región. Se tiene como objetivo determinar presencia y caracterización de microplásticos en los sedimentos costeros de tres zonas litorales (supra, meso e infra) y evaluar su potencial impacto ambiental a largo plazo. Se implementarán medidas de calidad y controles de contaminacio´n en la recolección y extracción de muestras. El análisis estadístico permitirá´ clasificar los microplásticos según tamaño, forma y composición química. Se busca evidenciar la presencia actual de microplásticos en los ecosistemas costeros y demostrar el riesgo que representan para el ambiente. Este estudio proporcionara´ información fundamental para comprender y abordar el problema de la contaminación por microplásticos en la región del Atlántico, contribuyendo así a la conservación y gestión adecuada de estos ecosistemas.
