Detección de microplásticos en tres especies de bivalvos provenientes de la provincia de Esmeraldas- Ecuador
AI summary Read the abstract
Researchers detected microplastics in three bivalve species from Ecuador's Esmeraldas province using alkaline and acid tissue digestion, optical microscopy, and infrared spectrometry, identifying fibers as the dominant morphotype and polyethylene, amines, methyls, and alkenes as the primary polymers.
La contaminación de los ecosistemas acuáticos a causa de la presencia creciente de plásticos ha recibido en los últimos años una importante atención en todo el mundo. En este contexto se determinó la presencia de microplásticos en A. tuberosa, A. similis y L. sp. provenientes de la provincia de Esmeraldas. Para la extracción de los microplásticos se realizó digestión alcalina y ácida del tejido blando de los tres especímenes, la observación de las propiedades físicas de los microplásticos se realizó mediante microscopía óptica y se usó espectrometría de infrarrojo para la identificación de los polímeros presentes en los microplásticos. Se determinó que el morfotipo predominante fueron las fibras, seguido de los fragmentos y los polímeros identificados en los microplásticos fueron: polietileno, aminos, metilos y alquenos. Este estudio aporta a la limitada información dentro del tema de estudio y servirá como base para estudios futuros referentes a microplásticos.

AI summary Read the abstract
Researchers characterized microplastics in the marine snail Thaisella chocolata collected from two zones near Matarani Port in southern Peru across winter and spring 2021, finding microplastics in 100% of individuals with filaments and fibers dominant, blue as the most common color, and six polymer types identified by Raman microscopy, suggesting T. chocolata is a viable bioindicator of coastal microplastic pollution.

Presence of microplastics in three bivalve species on the coastal fringe of Bajo Alto, El Guabo, Ecuador
AI summary Read the abstract
Researchers tested three types of edible shellfish (clams and mussels) from coastal areas near Bajo Alto, Ecuador, finding 1,413 microplastic particles, mostly thread-like fibers, across 91 animals. Anadara tuberculosa clams had the highest counts, and the most contaminated collection sites were located near urban areas.
