Resumen
La contaminación plástica está convirtiéndose rápidamente en una amenaza global, siendo considerada como uno de los indicadores más destacados para evaluar el impacto humano en los animales. En este contexto, se realizó un estudio con el objetivo de analizar la presencia de microplásticos en equinos de la provincia del Guayas, Ecuador. Se tomaron muestras de heces de 100 caballos de diferentes edades en tres ubicaciones. Se utilizó una versión modificada de la técnica de Willis-Molloy, las muestras se homogeneizaron con solución salina sobresaturada en una probeta de cristal, se incubaron a 37,5 °C durante 4 horas, luego se tomó el sobrenadante con una pipeta, el cual se colocó en una placa portaobjetos, seguido con un cubreobjetos. Posteriormente, se observó con un microscopio para determinar la existencia de microplásticos. El análisis estadístico reveló una presencia del 77% de microplásticos con diferentes tipos, siendo la línea/fibra la más encontrada de los 77 caballos expuestos. Se debe resaltar que la presencia de microplásticos no tuvo diferencias significativas en las variables: raza, sexo, edad, tipo de actividad, tipo de alimentación, marca de balanceado, tipo de microplásticos y fuente de agua, pero sí hubo una presencia más alta en equinos mayores a 18 meses, lo cual sugiere un efecto bioacumulativo.
The plastic pollution is rapidly becoming a global threat, being considered as one of the indicators to assess the human impact on animals. In this context, a study was conducted to analyze the presence of microplastics in horses in the Guayas province, Ecuador. Samples were taken from the feces of 100 horses of different ages in three locations. A modified version of the Willis-Molloy technique was used; the samples were homogenized with oversaturated saline solution in a glass beaker, incubated at 37.5°C for 4 hours, and then the supernatant was taken with a graduated glass pipette, which was placed on a glass slide and covered with a coverslip. Subsequently, it was observed under a microscope to determine the existence of microplastics. The statistical analysis revealed a prevalence of 77% of microplastics with different shapes, fibers being the most common, it should be noted that the presence of microplastics did not show significant differences in the variables: breed, age, sex, types of activities, brand of the feed, type of alimentation, shape of the microplastic and source of water. There was a bigger existence of microplastics in equine older than 18 months suggesting a bioaccumulative effect.
