Microplásticos en sedimentos fluviales en dos quebradas aledañas al centro poblado de Madeán, distrito de Madeán, Provincia de Yauyos, Región Lima, Perú

Abstract: Los microplásticos (MPs) están omnipresentes en el ambiente, por ejemplo, las quebradas intermitentes aledañas al centro poblado de Madeán son usadas como botaderos, en el cual hay presencia de plásticos y por ende la probabilidad de encontrar MPs. El objetivo de este estudio fue determinar la abundancia, tipos y características (tamaño, morfología y color) de MPs en sedimentos superficiales en dos quebradas. Se recolectaron muestras de sedimento superficial en las dos quebradas: quebrada Ishoj (11 sitios de m… Show more

“…Fibers, fragments and film were found in sediments in this irrigation channel (Canchari & Iannacone, 2022). Similarly, the same MP morphologies were described in the sediment of the Ishoj creek, possibly because rainwater flows into this stream (Canchari, 2022).…”

“…The lines in Figure 1 show the ditches formed by the action of rainwater runoff, having different outlet points, mainly to the mouth of the irrigation channel of Yuncaypara and towards the Ishoj creek. These results suggest that the sediments and rainwater runoff from the village of Madeán described in the present study contribute MPs to the sediment of the irrigation canals (Canchari & Iannacone, 2022) and the Ishoj creek (Canchari, 2022), but atmospheric deposition is also a factor that influences the presence of such synthetic particles, and MPs are transported over long distances in the atmosphere (Beaurepaire et al, 2021;Li et al, 2022).…”
