Microplastics are tiny particles present in the environment ecosystems, especially water, their presence is related to the inadequate management of plastic waste generated by the massive consumption of various productive activities. The main sources of microplastic pollution are waste present in rivers and surface waters, as well as wastewater from industrial and domestic activities. At the national level, few studies have been carried out on the identification of microplastics in sediments and to date, none in Wastewater Treatment Plants. For this reason, this research considers the discharge of the effluent from the San Jerónimo WWTP as a study unit, with the objective of identifying the presence of microplastics. Likewise, a descriptive level, quantitative methodology with a non-experimental research design was applied, where simple samples were taken at 3 sampling points with 7 replications. Of the total samples analyzed, the results identify 6208 und/L of microplastics. According to their morphology, a greater quantity of fragment type was identified (37%), in terms of color, translucent predominated (54.36%) and in a lesser quantity, yellow (1.78%). Regarding size by shape, the fiber type has the largest size with an average of (1023.22 μm), and the fragment type with (111.72 μm) represents the smallest size. 5 types of polymers were identified corresponding to; Polyethylene (PE) 35%, Polypropylene (PP) 32%, Polyamide/Nylon (PA) 19%, low density polyethylene (LDPE) 11% and Polyvinyl chloride (PVC) 6%. The data collected establishes a baseline that is valuable to understand the current context of microplastics in treated wastewater from the San Jerónimo WWTP.
