Abstract The current researches on microplastics in different water layers of reservoirs remains limited. This study aims to investigate the within a source reservoir. Results revealed that abundance ranged from 2.07 n/L 14.28 (reservoir, water) and 3 7.02 (river, water), while varied 350 714 n/kg (dw) sediment) 299 1360 sediment). average surface, middle, bottom were 6.83 n/L, 6.30 6.91 respectively. Transparent fibrous smaller than < 0.5 mm identified as predominant fraction with Polypropylene Polyethylene being prevalent polymer types. Additionally, pollution load index, hazard risk index calculated for sediments. showed surface exhibited moderate level sediments posed low risk. Both middle elevated levels due higher concentrations polymers significant toxicity indices. presents novel findings distribution layers, providing crucial data support understanding migration patterns facilitating prevention efforts.

Microplastics (MPs) as emerging contaminants have become a major global concern, however, the distribution and origin of MPs in Qinghai-Tibet Plateau (QTP) their impacts on ecosystem are poorly known. Hence, we systematically evaluated profile representative metropolitan locations Lhasa Huangshui Rivers scenic sites Namco Qinghai Lake. The average abundance water samples was 7020 items/m3, which 34 52 times higher than those for sediment (206.7 items/m3) soil (134.7 items/m3), respectively. River had highest levels, followed by Lake, Namco. Human activities rather altitude salinity impacted areas. Besides consumption plastic products locals tourists, laundry wastewater exogenous tributary inputs, unique prayer flag culture also contributed to emission QTP. Notably, stability fragment were crucial fate. Multiple assessment models employed evaluate risk MPs. PERI model took MP concentration, background value toxicity into account, comprehensively describing differences each site. large PVC proportion Lake posed risk. Furthermore, concerns should be raised about PVC, PE PET Rivers, PC Risk quotient suggested that aged sediments slowly released biotoxic DEHP cleaned up promptly. findings offer baseline data QTP ecological risks, providing important support prioritization future control measures.
