In the COVID-19 pandemic, the generation and composition of municipal solid waste could vary. This study investigated the quantity and composition of municipal solid waste in times of the COVID-19 pandemic in the Madeán Town Center, Madeán District, Yauyos Province, Lima Region, Peru. The total solid waste was separated into eight fractions: paper / cardboard, plastics, organic, textile/leather, metals, electricity/electronics, glass, and others. Its percentage composition by weight was determined for six weeks between September and October 2020. The results showed that the average amount of weekly solid waste was 466.46 Kg ± 82.99 Kg. Regarding the composition, the organic fraction represents the largest part with 75.07%. In addition, in the Populated Center far from the capital, there is evidence of a minimal generation of bio contaminated waste, with a weekly average of 0.3 Kg ± 0...

Microplastics (MPs) in irrigation canals have been little studied in Peru. The objective of this study was to determine the abundance and characteristics (size, color and shape) of MPs in surface sediments of earth canals for irrigation (Yuncaypara and Mejorada) located in the populated center of Madean, Madean district, Yauyos province, Lima region, Peru. Each site was sampled in triplicate, 1 site in Mejorada Channel (CM) and 2 sites in Yuncaypara Channel (CY1 and CY2). Separation was performed with high density saline solution (ZnCl , zinc chloride). The results showed the abundance in CM, CY1 and CY2, 2 which were 111.11 ± 19.25; 566.67 ± 88.19 and 66.66 ± 0.00 Items/kg of dry sediment, respectively. The characteristics of size, color and shape, the predominant ones were small MPs (6-1000 μm), blue and fragment, respectively. Pellet and foam were not found. It is concluded that t...
