This study assesses the pollution levels of Dal Lake in Kashmir, India, focusing on spatial distribution, abundance, and risk heavy metals surface sediments. Granulometric analysis revealed a complex interplay sedimentation processes, characterized by wide range sand (1.25% to 47.03%), silt (2.65% 58.21%), clay (38.35% 94.48%) contents across sediment samples. The average CaCO3 content 18.65% is notably higher than observed other regional global lakes, indicating production or preservation carbonates. organic matter (OM) within samples varied significantly, ranging from 3.9% 25.01%, reflecting sedimentary dynamics. Utilizing environmental assessment indices (Contamination Factor, degree contamination, Pollution Load Index, Potential ecological index, Enrichment Geo-accumulation Index) multivariate statistical analyses (Pearson's Correlation, Principal Component Analysis, Cluster Analysis), it examines contamination Iron, Manganese, Cobalt, Chromium, Copper, Nickel, Lead, Zinc 32 Results indicate variability metal concentrations, with Cobalt 24.1178 ppm 52.95 Iron 25,800.99 164,747.82 ppm, highlighting areas significant potential risks, especially which exceeds safe for benthic invertebrates. Index suggests moderate lake. These findings emphasize urgent need continuous monitoring effective management protect Lake's integrity.

Lake sediments serve as a sink for trace elements and provide record of watershed changes resulting from anthropogenic activities natural processes. In this study, eight in the Aha, an urban lake Guiyang City, Southwest China, were investigated to reveal effects historical coal mining rapid urbanization watershed. Results showed that median contents measured order Zn (220.00 mg/kg) > Ni (98.16 Cr (70.26 Cu (66.20 As (58.14 Co (41.66 Pb (28.33 Cd (1.39 mg/kg). Except Pb, concentrations Cd, As, Zn, Ni, Co, 4.64, 2.33, 2.00, 1.92, 1.81, 1.09 times higher than regional background values respectively. Trace element center significantly rest sediment cores, relatively stable hydrodynamic processes region. Vertical variation indicated fluctuations intensity tributaries effectively tracked by variations levels middle layer Youyu River Baiyan estuaries. The elevated surface Jinzhong estuary reflected basin over past 20 years. PMF analysis demonstrated mixture activities, Cu, originated mining. This study provides important information comprehending small-scale lakes environmental changes.
