“…The presence of Fe, Zn, and Pb can be attributed to a common source such as sulfide minerals already existing in most soils as pyrite (FeS 2 ), sphalerite (ZnS), and galena (PbS). Fe and Mn are mainly associated with minerals present in the soil [ 36 ], which determines the long-term stability of trace elements.…”

“…The geo-accumulation index method (I geo ), also called the Muller Index [ 14 ], has been widely applied in the assessment of soil pollution [ 15 , 16 , 17 , 18 ]. The calculation formula for I geo is as shown in Equation (1) :

where C i is the measured concentration of heavy metals in the soils, and S i is the geochemical background concentration value of the corresponding measured heavy metals in China.…”

“…Abandoned mines associated with serious land degradation have been attracting worldwide attention for their great threat to the environment, ecosystem and human health due to mining waste, tailings and acid mine drainage, and also for their potential for land reutilization (Dewil et al, 2006; Lin et al, 2005; Ok et al, 2011). These abandoned mines continue to release trace metal(loid)s (TMs) into the soil and water for decades without rehabilitation (Antoniadis, Shaheen, et al, 2017; Kusin et al, 2019; Tack et al, 2019). For example, abandoned tailings pollution (especially Cd and As) may cause biodiversity reductions and increased risk of disease in surrounding residents (Hudson‐Edwards, 2016).…”

Recently sustainable and efficient land development and the potential reutilization values of abandoned mines (i.e., industrial, arable, and tourism) have been attracting worldwide attention. However, environmental impacts after rehabilitation practices are often ignored and field data are lacking. What remains unknown is an understanding how the risk of soil trace metal(loid)s (TMs) respond to short-term rehabilitation of abandoned gold mines and the potential value for following targeted remediation. We found that a high level of TM cadmium (Cd) and arsenic (As)] contamination and significant health risk to humans, limited land reutilization in rehabilitation scenarios. Feedback from soil TMs to rehabilitation is of potential value for following targeted remediation. Specifically, (1) the major pollutants we studied were Cd and As. Cadmium poses a considerable ecological risk as evidenced by I geo , contamination factor, E i r and risk assessment code, and a much higher bioavailability evidenced by non-residual fractions (42.42%). Arsenic has the lowest environmental availability with 90.99% in residual fraction; (2) spatial distributions of TMs were similar. Sites with serious contamination were mainly located in the southwest of the study area, close to the abandoned mine; Results of principal component analysis suggested that mining activities were the main anthropogenic pollution sources;(3) there was no non-carcinogenic risk and a higher carcinogenic risk was found in adults than in children. Targeted remediation techniques are needed to mitigate carcinogenic risks posed by As and Cr. This study emphasized the necessity of assessment of soil TMs risk in abandoned gold mines with short-term rehabilitation and offered crucial data utilized to optimize time parameters (short-term) towards sustainable and efficient land development.
