“…Heavy metals enter the soil mainly through atmospheric deposition, sewage irrigation, and slag percolation, resulting in various levels of heavy metal contamination in cultivated land around a smelter [7,[11][12][13]. Many studies have shown that heavy metal pollution in soil around nonferrous metal smelting areas is very serious [4,[14][15][16]. The Pb/Zn smelting is an important source of heavy metals in soil [8,9,11,16,17].…”

The Pb/Zn smelting is an important source of heavy metals in soil [8,9,11,16,17].

“…At present, the research at home and abroad in Pb/Zn smelting areas mainly focuses on pollution and risk assessment of soil and crops around smelting areas, and the research areas are mostly small or medium-sized [4,14,16,[24][25][26][27]. There is a lack of comprehensive evaluation of the differences in pollution degree and potential ecological risk in different regions.…”

Nonferrous smelting is an important source of heavy metals in soil, which causes different degrees of soil pollution, especially in lead–zinc (Pb/Zn) smelting areas. Based on the Pb/Zn environmental release during the Pb/Zn mineral smelting processes in 31 Chinese provinces from the period 2000 to 2015, the study analyzed the spatiotemporal variations in Pb/Zn environmental release at the national level and then evaluated the degree of soil pollution and potential ecological risk based on the heavy metal content in soil from Pb/Zn smelting areas. The results showed that from the period 2000 to 2015, the Pb release had a discrete trend, transferring from the middle east to the west, and the provinces with higher Pb releases were Henan Province, Yunnan Province, and Hunan Province. However, the Zn release showed a tendency towards spatial aggregation, and the release center of this heavy metal presented a shifting trend from south to north; additionally, the release of Zn was highest in Hunan Province. The pollution index analyses indicated that Cd, Pb, Cu, and Zn in Zhuzhou and Huludao all reached extremely polluted levels, while Tongguan was at a safe level. In Gejiu, Mianxian, Fengxian, Zhuzhou, Huludao, and Shaoguan, there were very high potential ecological risks, with Cd having the highest potential ecological risk in most smelting areas, followed by Pb.

“…In the past, Pb smelting depended heavily on sintering techniques using simple facilities that had low ore metal recovery; this smelting technique contributed greatly to environmental heavy metal(loid)s pollution via particulate deposition. Historical, atmospherically deposited heavy metal(loid)s–containing particulate matter has been proven to enhance soil metal concentrations in smelter vicinities (Douay et al., 2013; Lee, Kang, Yu, & Kwon, 2020; Xing, Zheng, Scheckel, Luo, & Li, 2019a).…”

“…Lead smelting techniques have improved in recent years, and thus ore recovery has improved. However, due to past environmental pollution and the concern regarding heavy metal(loid)s pollution effects on local soils, crops, and residents, some nonferrous metal smelters have been closed (Douay, Roussel, Pruvot, & Waterlot, 2008; Gelly et al., 2019; Lee et al., 2020; Van Pelt et al., 2020). Regardless of site closures or improved smelting techniques at existing facilities, areas near former/current smelters continue to contain elevated soil heavy metal(loid)s concentrations.…”

Atmospheric deposition samples were collected over 15 mo at several locations near an operating smelter and an abandoned Pb smelter to investigate the contribution of Pb smelting to depositional fluxes and potential local air quality degradation. Samples were analyzed for As, Cd, Cu, Pb, and Zn and subjected to scanning electron microscopy (SEM)-energy dispersive spectroscopy (EDS). Concentrations of Cd and Pb at both sites were greater than at the control site (p < .05), and significant correlations existed between Cd and Pb concentrations at both sites (p < .05). Monthly depositional flux variations at both sites were similar, with greater deposition during cold and dry periods. Heavy metal(loid)s deposition during these periods was correlated with wind speed. Greater Cd depositional flux differences were found between the smelter and control sites compared with other elements. The SEM images suggested that some particles at the operating smelter site were from Pb smelting material. However, most particles at both sites had no characteristics of smelting, suggesting reactions occurred between the smelter-emitted particles and soil components. The EDS results indicated that atmospheric deposition from both sites had lower Pb concentrations than smelting material or ash. The main atmospheric deposition source at the operating and abandoned sites was likely from the resuspension of heavy metal(loid)-enriched soil particles. Greater risk of air pollution from historical Pb smelting facilities exists years after closing down. Reducing soil wind erosional losses may help reduce heavy metal(loid)s dispersion across environments. 1 INTRODUCTION Nonferrous metal mining and smelting are main sources of environmental heavy metal(loid)s pollution (Ettler,
