“…This correlation was further veri ed by the positive correlation of plant height, stem and leaf dry weight, stem and leaf fresh weight, and root dry weight with the nutrient elements of the tailing substrate. The main mechanism of action may be that the nitrogen-phosphoruspotassium-source amendments increase the metabolic activity of soil microorganisms, which promotes the soil maturation process of the tailings substrate and facilitates the settlement and growth of plants [19][20][21] . The observations align with ndings from earlier research.…”

Phytoremediation is widely regarded as the most environmentally sustainable green technology for remediating mineral waste. The appropriate ratio of amendments can improve the substrate environment for plant growth and improve the repair efficiency. Study its improvement effect on tailings wasteland from the aspects of plant growth and nutritional elements. Considering that, this study explored the effects of water and fertilizer treatment on the physical and chemical properties and plant growth of quarry waste matrix with different ratios. The original soilwithout fertilizer and 45% water treatment was used as the control group (CK), and and the composite soil with different ratios of original soil and slag and various water and nitrogen fertilizer treatment combinations was used as the experimental group. Pennisetum alopecuroides (L.) Spreng, Campsis grandiflora (Thunb.) Schum, Setaria glauca (L.) Beauv, Periploca sepium Bunge and mugwort (Artemisia argyi Levl. Et Vant.)were planted in the control group and the experimental group respectively. After 30 days of nitrogen fertilizer and water treatment, an analysis was conducted to assess the physicochemical properties and the plant growth status of the tailing matrix for each experimental treatment. The results showed that the M5 treatment fostered the growth of Pennisetum alopecuroides (L.) Spreng and mugwort, while the M2 treatment promoted the growth of Campsis grandiflora (Thunb.) Schum, and the M3 treatment was beneficial to the growth of Setaria glauca (L.) Beauv and Periploca sepium Bunge. The soil matrix pH of Pennisetum alopecuroides (L.) Spreng, Campsis grandiflora (Thunb.) Schum, setaria glauca (L.) Beauv, and Periploca sepium Bunge and mugwort are all greater than 7.5, and macronutrient elements such as TK, AK, TN, AN, TP, and AP all have certain levels of improvement. PCA analysis showed that there were significant differences in substrate properties and plant growth properties between treatments for Pennisetum alopecuroides (L.) Spreng, Campsis grandiflora (Thunb.) Schum, Setaria glauca (L.) Beauv, Periploca sepium Bunge and mugwort (P<0.05). Correlation network and structural equation analysis showed that the water and fertilizer10 matrix had a significant positive correlation with soil AN and TN (P<0.05), and TK had a positive correlation with the growth status of five plants. The water and fertilizer substrate has a positive correlation with the growth status of Pennisetum alopecuroides (L.) Spreng, Setaria glauca (L.) Beauv, Periploca sepium Bunge and mugwort, and a negative correlation with the growth status of Campsis grandiflora (Thunb.) Schum.

“…Many researchers investigated the contamination level, spatial distribution pattern, and transformation machinimas of arsenic and HMs in the surrounding soil of mining areas (Sherriff et al, 2006;Loredo-Portales et al, 2020;Hao et al, 2022;Saha et al, 2022). Punia and Siddaiah (2019) assessed the mobility and behaviour of Cu, Zn, Ni, Cr, and Pb in mine tailings and neighbouring soils in the Khetri copper mine region, Rajasthan, India, finding the mobility order is Ni > Zn > Cu. The study by Wu et al (2017) showed that the surface water of mining area was the main carrier of arsenic migration into soil, while wind and microorganisms played an important role in arsenic entering the atmosphere.…”

Understanding the characteristic heavy metals and their migration-transformation behavior in mining areas is essential for the prevention and control of mining pollution. This study selected a gold mine in the Anqing-Guichi ore-cluster region in the Middle-Lower Yangtze metallogenic belt as the research area, the concentrations, and migration-transformation mechanisms of metalloid As and typical heavy metals (Cd, Zn, Pb, Cu, Cr, and Ni) in gold mining wastes (mine tailings and sewage sludge) and the surrounding soil (farmland soil and soil a mining area) were investigated. The results showed that the concentration of As was high in both mining wastes and soils, and the geo-accumulation index values of As in soils ranging from 1.44–6.70, indicated that As pollution was severe in the soil. Besides, a close correlation between the concentration of As and the content of iron was observed by XRF analysis, in conjunction with SEM observations, most As-bearing phases are embedded in Fe, O, and Si compounds. According to EDS and XPS results, the Fe-O-As particle was suggested to be Fe-(oxy)hydroxides with absorbed or co-precipitated As. Furthermore, the arsenic phase observed in the soils were consistent with the weathering oxidation products in the tailings, demonstrating that the mineral particles in the tailings could migrate into soils via atmospheric transport, rainwater leaching, surface runoff, etc., and consequently result in heavy metal accumulation. The sequential chemical extraction result showed that the residual state of As in the soil exceeded 60%, and As posed no risk to low risk according to the Risk assessment code result. However, due to the high concentration and high mobility of arsenic, its environmental impact cannot be ignored even if its bio-accessibility in mined area soil is low.
