To investigate the influence of factors such as tourism, agriculture, and population density on presence microplastic (MP) content in aquatic environments their associated ecological risks, Jingpo Lake, a remote high-mountain lake situated away from urban areas, was selected research subject. This study examined abundance, types, sizes, colors, polymer compositions MPs within water body, fish, sediments. By considering variables, including fishing practices, agricultural activities, dynamics, vegetation cover, an analysis conducted to unravel spatial temporal distribution concerning human ultimately leading assessment risks posed by MP pollution. The findings revealed that average abundance lake's surface recorded (304.8 ± 170.5) n/m3, while sediments, it averaged (162.0 57.45) n/kg. Inside digestive tracts measured at 11.4 5.4 n/ind. contamination environment Lake found be relatively minimal. Variations loads across time space were observed, with predominantly falling size range small planktonic organisms (50-1000 μm). Additionally, prevalent colors samples white or transparent, constituting approximately 55.65% entire composition. Subsequently, they black, red, blue. consistent extracted fish sediment samples. chemical comprised PE (31.83%) PS (25.48%), followed PP (17.56%), PA (11.84%), PET (6.71%), EVA (4.56%), PC (2.03%). Regarding seasonal aspect, concentrations highest during summer (46.68%), spring (36.75%) autumn (16.56%). Lake's sediments notably influenced confirmed Pearson correlation coefficients. A strong association observed between levels quality indicators ammonium nitrogen (NH4-N), total phosphorus (TP), chlorophyll-a (Chla), suggesting human-related pollution contributed significantly contamination. diversity pollutants exhibited variability composition (1.23 1.79) using Shannon-Wiener Index. ranged 0.59 1.54, shape 0.78 1.30, 0.83 1.10, 0.44 1.01. results risk highlighted categories for water, categorized I PHI PLI "Minor" PERI. These low-risk values attributed low toxicity distributed basin. Moreover, interconnected local activities around sampling sections.
