“…The information containing in a suit of soil profile can reflect the soil physical and chemical processes at a specific site ( Liu et al, 2016b ; Vodyanitskii & Yakovlev, 2011 ). Previous researches have mainly focused on the spatiotemporal variations and the contamination of HMs in human-affected regions, for examples, sewage irrigation area, polluted farmland and mining area ( Khanal et al, 2014 ; Kong et al, 2018 ; Liu et al, 2016a ; You et al, 2015 ). However, the studies of HMs characteristics in soil profile were mostly aimed at a single land-use type ( Balabane et al, 1999 ; Vodyanitskii & Yakovlev, 2011 ).…”

Background Soil heavy metals (HMs) under different land-use types have diverse effects, which may trigger the ecological risk. To explore the potential sources of HMs in karst soils, the spatial distribution and geochemical behavior of HMs based on different land-use types are employed in this study. Methods Soil samples (n = 47) were collected in three suites of karst soil profiles from the secondary forest, abandoned cropland and shrubland in Yinjiang, Southwest China. The concentrations of Ni, Mn, Cr, Pb, Cd and Mo were determined to give a comprehensive understanding of the possible sources of these HMs and evaluate the potential ecological risk in Yinjiang County. Results The mean concentrations of HMs in all profiles followed the same order: Mn > Cr > Ni > Pb > Mo > Cd. Meanwhile, the concentrations of most HMs roughly increased with the depth. Additionally, the concentrations of HMs were mostly correlated with soil pH and SOC, rather than with clay and silt proportions. By contrast, with the enrichment factors (EF), geo-accumulation (Igeo) and potential ecological risk index (PERI) of HMs in soil under different land-use types, the results indicated that these HMs exhibited non-pollution (Igeo < 0) and no ecological risk (PERI < 30) to human health in soils of Yinjiang County. Conclusions The distribution of HMs is dominated by weathering in the karst area, and the effects of agricultural inputs on the enrichment of soil HMs in Yinjiang County are limited. This further state that the arrangement of the local agricultural structure is reasonable.

“…Further complex correlations among heavy metal contents across the different soil types were revealed. Notably, different correlations were observed between the heavy metal contaminants, which exhibited different sources and pathways of enrichment [37]. Cadmium was negatively correlated with other elements in area A, where the correlation coefficient with zinc was as low as −0.895 *, suggesting a special source of Cd pollution in the area.…”

Coal mining activities have a series of impacts on the local eco-environment, such as air pollution due to the release of toxic gases, contamination of soil with heavy metals, disturbance and contamination of surface and subsurface water, and damage to land resources with surface subsidence and accumulation of solid waste materials. This study investigated the distribution of heavy metals in mining sites by analyzing the heavy metal content in soil samples from different sites in the Dahuangshan mining area of the southern Junggar coalfield (Xinjiang, China). The results show that area C has the highest Cu content; and area B has the highest Mn content, the highest Zn content, the highest As content, and the highest Cd content, which indicate that area B underwent potential multiple heavy metal contamination. It also shows that the Cd is the major heavy metal for all three areas. The different eco-environmental indices, including the Nemerow comprehensive pollution index, the geo-accumulation index, and the potential ecological risk index, all show the same results, i.e., that Cd is the major potential contaminant in all three types of soil.

“…Huainan Coal eld is an national coal base and coal-electricity base in northern Anhui Province of central China (You et al, 2015). Mining activities are important sources of energy and provide resources for national and local economic development, coal gangue pile generated by mining activities have a great adverse impact on soil quality, ecological environment, human health, and become the primary source of toxic metal pollution in soil (Li et al, 2022).…”

To better understand the toxic metal pollution caused by coal mining activities, the concentrations of Ni, Zn, Cr, Cd, Cu, As and Pb in the soil around the coal gangue hill in a coal mine area of Huainan, China were measured, the soil pollution was assessed with the single factor index method, Nemerow pollution index method and potential ecological hazard index method. The average concentrations of Ni, Cu, Zn, Pb, Cr, Cd and As were 20.75, 17.68, 29.86, 10.33, 46.91, 0.14 and 21.59 mg/kg, respectively. The descending order of the average concentration is Cr > Zn > As > Ni > Cu > Pb > Cd. The concentrations of toxic metal contaminants in the soil showed distinct spatial distribution differences in different wind directions. The pollution degree is followed the order of downwind direction > upwind direction > control point. The ecological risk of toxic metal contaminants in the soil around the mining area in the upwind and downwind directions belonged to slight, Cd and As posing a higher ecological risk than the other elements. Results revealed that the wind direction is important for the distribution of toxic metal contaminants around the coal gangue hill. This study can be used as a scientific reference for the prevention and control of pollution caused by toxic metal contaminants in mining area soil.
