The long-term storage of coal gangue (CG) mountains causes serious environmental problems such as water and air pollution. Thus, sustainable reclamation practices are urgently needed to minimize the impacts brought by CG mountains. Pikovskaya medium was employed screen microorganisms, which were subsequently utilized promote solubilization CG. XRF, SEM, XRD, HPLC techniques characterize before after bacterial treatment. In this study, we have successfully isolated purified a strain, identified Stenotrophomonas bentonitica BII-R7, possesses ability facilitate nutrient elements from Factors including initial inoculation ratio, incubation time, particle size, concentration, pH, temperature examined investigate their effects on biosolubilization Furthermore, mechanism underlying also probed. Our data demonstrated that low-molecular-weight organic acids, acetic acid formic acid, may harbor crucial role in promoting Lastly, found conjugation with CG, can increase alfalfa seed germination percentage growth alfalfa. Together, these provide evidence bacterial-treated be for soil improvement land reclamation.

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.
