To investigate the changes in heavy metal content sub glacial water during freezing and thawing process of seasonally frozen lakes, Wuliangsuhai Lake northern China was taken as research object. The ice thickness, depth, at different depths lake were measured periods. Based on a large amount data, MATLAB 2022b software is used to model data fitting optimization identification, wavelet analysis 24 h sliding average method are for verification describe variation concentration with depth time. results show that periods level constantly changing, but below follows same distribution depth. During process, increases increase thickness. A new numerical describing spatiotemporal metals under period obtained through calculation. overall trend simulated contour lines consistent values has small error. This study provides reference predicting cover cold arid regions. can be simulate times.

Abstract Sediments in agricultural ecosystems serve as critical indicators of environmental pollution, particularly regions subjected to intensive practices. This research evaluates the hazards and implications heavy metal (HM) contamination river sediments from Sidi Allal Tazi area within Morocco’s Sebou basin. Twenty sediment samples were extracted strategically designated locations, levels analyzed using a multi-index integration approach, multi-statistical analyses (MSA), Geographic Information Systems (GIS). The results revealed considerable spatial variability HM concentrations, with Cd As displaying highest levels. Statistical analysis, incorporating Principal Component Analysis (PCA), identified anthropogenic activities primary contributors contamination. Hierarchical Cluster (HCA) categorized metals based on common pollution pathways, while GIS mapping distribution across vulnerable areas. Pollution like Geo-accumulation Index (Igeo) well Load (PLI). that 75% sites under “very high pollution”, emphasizing severity Contamination Factor (CF) classified 90% 100% contamination”. Risk indices indicated significant ecological threats, contributing an RI exceeding 600 many areas, signifying risk”. These findings highlight urgent need for targeted mitigation strategies sustainable methodologies provides comprehensive framework assessing managing contamination, offering insights policymakers managers.

To investigate the status of heavy metal pollution and associated ecological health risks in farmland surrounding Xicheng lead zinc mining area, we collected soil samples (0–20 cm) measured level As, Ni, Cu, Zn, Cd, Pb, Hg, Cr. The characteristics metals, levels, ecological, were quantitatively assessed using Monte Carlo simulation conjunction with geo-accumulation index (Igeo), (Pi), risk (Er), human assessment model. results indicated that average concentrations Cr study area 26.92, 39.46, 31.18, 340.23, 1.13, 184.61, 0.34, 71.15 mg·kg−1, respectively. These values significantly higher than background levels reported for Gansu Province. Igeo Hg was 3.27, Er 679.13, indicating had highest accumulation posed greatest area. single-factor Cd 2.52, marking it as level. cumulative probability derived from indicates non-carcinogenic hazard indices adults children 2.79 × 10−1 1.67, respectively, 94.82% exceeding threshold. carcinogenic (TCR) 8.09 10−5 4.60 10−4, 100% exceeded TCR standard children. As identified primary contributors to both risks. findings enhance our understanding contamination soils establish an empirical framework developing targeted remediation approaches sustainable land management practices.
