The main objective of this research was to evaluate the presence of microplastics in sediments and in the Odontesthes regia from the Acopia lagoon, located in the district of Acopia, province of Acomayo, department of Cusco. Twelve sediment samples were collected for convenience due to limited geographic accessibility, and twelve samples of Odontesthes regia, commonly known as silverside, were randomly selected to observe the presence of microplastics. For processing the sediment samples, drying tests, magnetic agitation, density tests, and infrared spectroscopy were employed. To evaluate microplastics in the Odontesthes regia, the digestive tract was extracted through a longitudinal incision and organic matter was removed by applying 12.75% hydrochloric acid (HCl), commercially known as muriatic acid. The results showed a positive presence of microplastics in white, blue, green, and red colors, as well as polypropylene, high-density polystyrene, and PVC in the Acopia lagoon. However, no microplastics were found in the Odontesthes regia. It was concluded that there is a presence of microplastics in the sediments of the Acopia lagoon, especially in areas near the population, due to the influence of human activity, mainly agriculture, which is the primary economic activity of the population near the lagoon. Additionally, it was determined that the microplastics present in the Acopia lagoon do not impact consumable species, such as Odontesthes regia.
