“…Figure 4 shows the relationships between As, Cd, Pb, and Zn based on linear regression models. Such relationships can indicate transport pathways or mechanisms from the metal(loid) sources [34,35]. Among the four elements investigated, Cd and Zn showed a high linear correlation (r � 0.890; Figure 4(e)), which supports the finding that Cd and Zn had similar distribution patterns in the agricultural fields located downstream of the mine tailing dumps (Figure 3).…”

“…Oxidation of the residual sulfides releases Fe and other metal(loid)s from the mine tailings, such as Pb, Cd, and Zn [43,44]. e wide variations of their concentrations in the agricultural soils of the study area can be attributed to the dispersion of the mine tailings (CVs in Table 3) because high CVs (>50%) are often reliable indicators of anthropogenic activity [34,35,[45][46][47]. Moreover, the hotspots of As, Cd, Pb, and Zn formed in the agricultural fields located downstream of the mine tailing dumps offer clear evidence for the dispersion of the mine tailings ( Figure 5).…”

“…In addition, most of the agricultural fields in the study area are paddy fields (Figure 1), which are periodically flooded and drained during the rice-growing season. Yun et al [34,35] noted that As transported to paddy soil can affect a wider area owing to the reducing conditions of the paddy soil and the hydraulic characteristics. Moreover, in this area, the traditional irrigation method is groundwater pumping, which has been maintained even after the construction of the reservoir in 1964 ( Figure S1).…”

We investigated the characteristics of metal(loid) transport and dispersion in agricultural soils near an abandoned metal mine. Topsoil samples were collected from 162 sampling sites in the study area, including 1 in the mine tailing dumps, to analyze the total concentrations of As, Pb, Cd, and Zn. Subsequently, the metal(loid) transport and dispersion characteristics were investigated using geographic information system (GIS) technology. The results of this study clearly demonstrated the variation in the dispersal of As, Cd, Pb, and Zn from the mine tailing dumps to nearby agricultural soils and the element-specific spatial variability in their respective transport and dispersion characteristics. These findings suggested that compared with the migration behavior of Cd, Pb, and Zn, that of As has a farther-reaching impact on agricultural soils owing to its geochemical cycling in the soil and groundwater environment. This impact differed significantly in magnitude from that of the other investigated metals. Therefore, special consideration must be given to the migration behavior of As.

“…Meanwhile, the soil criteria were presented from Canada [29] and China [23]. [37] Puling, Guangdong Worldwide, agricultural soil was hardly polluted by heavy metals in USA [24], India [25] and Korea [26]. However, heavy metal contamination in Greece was relatively higher than other countries in agricultural soil [27], whereas Hg contamination in Spain was relatively serious [28].…”

To assess contamination levels and ecological risks of heavy metals in agricultural soil from Shanxi Province of China, a total of 33 samples in the surface soil were collected from 11 cities in Shanxi. The soil samples were digested by a mixed acid of nitric acid and hydrofluoric acid on a microwave digestion system, then the levels of eight heavy metals were analysed using an inductively coupled plasma mass spectrometer. The pollution levels of soil heavy metals were evaluated using a geo-accumulation index and their ecological risks were assessed using risk index calculated by Hakanson's method. As a result, the average concentrations of the heavy metals As, Cd, Cr, Cu, Hg, Ni, Pb and Zn were 12.9 ± 4.8, 0.35 ± 0.23, 43 ± 14, 27 ± 19, 0.25 ± 0.14, 21.7 ± 5.7, 17 ± 13 and 89 ± 53 mg kg −1 , respectively. By comparison to the Chinese soil environmental quality (GB15618-2018), only 9% of Cd samples and 3% of Cu samples exceeded their corresponding screening criteria. Subsequently, the results of geo-accumulation indices suggested that Shanxi's soil suffered from moderate to heavy contamination posed by Cd and Hg, and risk indices exhibited a similar trend that Cd and Hg were the main contributors for considerable to very high ecological risk. Finally, the analysis of variance indicated that the mean levels of Cd significantly occurred at Yuncheng areas among the 11 cities ( n = 3, p < 0.05), but Hg concentrations did not have significantly statistical differences. This study demonstrated that metals Cd and Hg had higher levels and ecological risks for agricultural soil in Shanxi, especially, Yuncheng City suffered from heavy Cd contamination. The findings of the present study will provide basic information on management and control of the agricultural soil contamination in Shanxi Province, China.

“…Principal component analysis and cluster analysis were used to identify sources of metal(loid)s (Facchinelli et al 2001;Yun et al 2016). According to results of the eigenvalues from the PCA analysis (Tables 6.2 and 6.3), three principal components were considered for all studied areas, which account for over 90% of the total variance.…”
