“…Research has demonstrated that pollutants released into the environment by these industries can have long-term effects on ecosystems and human health that persist for years or even decades after the industries have declined or ceased operations (Mah, 2017). For instance, soil and water contamination from heavy metals and chemical by-products can disrupt local biodiversity and pose ongoing risks to public health for decades (Gao et al, 2021).…”

In this study, we investigate the relationship between industrial development, soil contamination by heavy metals, and the development of remediation technologies across European NUTS3 regions. Despite the recognized human and environmental hazards associated with products or by-products of industrial activities such as heavy metals (especially lead, cadmium, and mercury), the response to these environmental challenges varies significantly across regions. Our analysis proposes a novel approach to assess the complex relationship between human well-being and different types of regional industrialization by considering the local presence of heavy metals in soils and the filing of patents related to heavy metal remediation technologies. Findings show that non-deindustrialized regions demonstrate a proactive approach by significantly innovating in cleaning technologies in response to soil contamination. Conversely, regions experiencing deindustrialization show a limited response, likely due to a loss in industrial and technological capabilities or institutional weaknesses. By linking soil contamination data with technological innovation, this study offers new insights into the regional dynamics of environmental management and the critical role of recent industrial history in influencing technological responses to environmental challenges.

“…Previous studies have shown that land-use types have a certain impact on the migration and diffusion of soil-heavy metals [ 19 ]. For example, Chrastny et al [ 20 ] showed that forest soils are much more affected with smelting processes, while agriculture soils are much more affected by downward metal migration.…”

Soil-heavy metal pollution in mining areas is one of the problems in the comprehensive treatment of soil environmental pollution. To explore the degree of soil-heavy metal pollution and the human health risk in mining areas, the contents of soil As, Cd, Cu, Cr, Hg, Ni, Pb, and Cr(VI) in an abandoned gold mining area were determined. The geoaccumulation index (Igeo), single-factor pollution index (SPI), Nemerow comprehensive pollution index (NCPI), potential ecological risk index (PERI), and the human health risk assessment model were used to assess the pollution degree and the risk of soil-heavy metal pollution. Finally, the assessment results were used to provide remediation guidance. The results showed that (1) the average contents of As, Cd, Cr, Cu, Hg, and Ni in the mining area exceeded the background values of the soil elements. (2) The mining area was polluted by heavy metals to different degrees and had strong potential ecological hazards. (3) The total carcinogenic risk of heavy metals exceeded the health risk standard. The main components of pollution in the mining area were As, Cd, Cr, and Hg. Results from this study are expected to play a positive role in pollution treatment and the balance between humans and ecology.

“…Liu et al (2016) proposed a safe utilization classification and management strategy based on the single factor pollution index, Nemero pollution index, and potential ecological risk index. Gao et al (2021) determined the redevelopment priority of abandoned industrial and mining land through the comprehensive pollution risk rating of soil heavy metals. However, the aforementioned classification scheme only considers the total amount and exceedance of heavy metals in soil, ignoring the actual impact of heavy metals on crop safety and the ecological environment.…”

With global urbanization and industrialization, environmental pollution and food safety problems caused by soil heavy metal pollution occur frequently. To realize the safe utilization of cultivated land resources in high-risk areas of heavy metal pollution, we present an approach to safe utilization classification and management in this study. A typical agricultural area around industrial and mining enterprises located in the economic belt of the Yangtze River Delta was chosen as the research area with cultivated soil as the research object. A total of 1,139 geochemical survey sampling sites and soil survey data were used for this research. Initially, the potential ecological risk index was used to assess the potential ecological risk of heavy metals in cultivated soil, and key soil physical and chemical indicators were chosen to assess soil resilience. Next, the safe utilization classification of cultivated land was carried out by combining the potential ecological risk of soil heavy metals with soil resilience. Then, the specific classification management strategy was developed according to ecological risk factor types and crop types. The results showed that the production and operation activities of industrial and mining enterprises in the study area contributed significantly to soil Cd and Hg pollution, and the potential ecological risk of heavy metals in the surrounding soil was high. The soil resilience of cultivated land in the study area was generally not high. The clay content and cation exchange capacity (CEC) were the main strong restrictive indicators, while CaO, soil organic carbon (SOC), and pH were the main medium restrictive indicators. Natural conditions such as topography, hydrogeology, and soil-forming parent material differed by region, resulting in different restrictive factors. There were 16 safe utilization types in the study area. Different management strategies were proposed based on various soil potential ecological risks, soil resilience, ecological risk factor types, and crop types. This study can offer fresh perspectives on the safe utilization classification and management of land resources in high-risk areas of soil pollution and serve as a reference for sustainable intensification.
