Microplastic Contamination in the Pristine Waters of Tilicho Lake, Nepal: A Groundbreaking Study in the High-Altitude Himalayas

Table S1. Site-wise microplastic (MP) concentration information: Table includes MP sampling site details, sample collection date, and average MP concentration (in particles/Ltr) evaluated in each site.
Table S5. Detailed information on MPs recorded: Table includes details of MPs across six sampling sites, including MPs in blank samples, along with the morphological characteristics of recorded MP data—classified into categories, including color, shape, and size.
Workout Table: Table includes net MP concentrations after performing average blank corrections on each category of MPs recorded among sampling locations—prepared for statistical analyses
