In China, coal remains the dominant energy source, leading to substantial production of gangue. This study established comparative zones—a area and a control area—and applied Geo-Detector model (GDM), Absolute Principal Component Score-Multiple Linear Regression (APCS-MLR) model, cadmium isotope fingerprinting delineate origins heavy metal(loid)s (HMs) in soil proximate accumulations The contents (Cd), mercury (Hg), arsenic (As), lead (Pb) were significantly elevated relative control, whereas levels chromium (Cr), copper (Cu), nickel (Ni), zinc (Zn) displayed no marked differences between zones, underscoring an intensified pollution level region. integration GDM, APCS-MLR, Cd methods enhanced precision dependability identifying sources. Soil contamination was predominantly due persistent gangue accumulation, vehicular emissions, agricultural chemicals, contributing 40.1%, 33.7%, 26.2% respectively, while area, emissions activities main contributors. Surface runoff from accumulation emerged as pathway for area. underscores urgency implementing strategic management mitigation ecological hazards, particularly those associated with levels.

Land transportation is a major source of heavy metal contamination along the roadside, posing significant risks to human health through inhalation, oral ingestion, and dermal contact. Therefore, this study has been designed determine concentrations vehicular released metals (Cd, Pb, Ni, Cu) in roadside soil leaves two commonly growing native plant species (Calotropis procera Nerium oleander).Two busy roads i.e., Lahore-Okara road (N-5) Okara-Faisalabad (OFR) Punjab, Pakistan, were selected for study. The data collected from five sites each during four seasons. Control samples ~ 50 m away road. content i.e. lead (Pb), cadmium (Cd) nickel (Ni) copper (Cu) determined by using Atomic Absorption Spectrophotometer (AAS). Significantly high amount all studied observed both contrast control ones. mean concentration ranged as Cd (2.20-6.83 mg/kg), Pb (4.53-15.29 Ni (29.78-101.26 Cu (61.68-138.46 mg/kg) (0.093-0.53 (4.31-16.34 (4.13-16.34 (2.98-32.74 mg/kg). Among roads, higher was noted N-5 Significant temporal variations also roads. order different seasons summer > autumn spring winter. Furthermore, accumulation potential Calotropis than that oleander. sustainable management contamination, plantation recommended roadsides.

Heavy metals with a high concentration value in the soil are detrimental to ecosystem. In this study, 96 samples were taken from two sections (A-A, B-B) mouth of Juanshui River analyze heavy metal pollution. Soil pollution status and ecological risk investigated using Nemerow potential index. The sources affecting distribution characteristics exhibited based on Inverse Distance Weighted (IDW), principal component analysis (PCA), Statistics. Pollution had reached moderate level. Hg Cd main contributions. Coal burning agricultural chemicals predominant source study area. order avoid river becoming secondary for water bodies resulting vicious circle pollution, China should be mainly managed controlled.
