Assessing the suitability of urban and agricultural land is essential for planning sustainable urban and agricultural systems. The main objective of this study is to evaluate the suitability of land in Ioannina plain (western Greece) concerning the soil contents of two potentially toxic elements, cadmium (Cd) and cobalt (Co). Geochemical and spatial analysis methods were applied to assess the distribution of Cd and Co in the soil of the Ioannina plain and identify their origin. The primary anthropogenic sources of Cd and Co in the topsoil of the study area can be attributed to traffic emissions, aircraft operations, vehicle crushing and dismantling activities. Element content is compared to international guidelines and screening values. Cadmium and Co concentration in the soil of the study area is well above the European topsoil mean. Thus, the urban and agricultural lands cover the vast majority (92%) of the total area. Cadmium concentration in soil of the study area with a mean (mg kg−1) 1.7 and 2.0 was observed in agricultural and urban land use, respectively. Cobalt content in soil of the area studied with a mean (mg kg−1) 30.8 and 37.1 was recorded in agricultural and urban land use, respectively. Land evaluation suitability by adopting criteria provided from the international literature is discussed.

“…The rapid progress of urbanization, industrialization, and agriculture has led to an escalating transfer of heavy metals to the soil, posing a severe threat to the soil environment and food safety [1][2][3]. Due to their elevated toxicity, persistence, and resistance to degradation, heavy metals present a more formidable challenge to soil compared to other pollutants, demanding heightened attention [4,5].…”

Farmland soil quality is a crucial determinant for agricultural productivity, food safety, and human well-being. Among the various contaminants, heavy metals have emerged as pervasive factors significantly impacting farmland quality, attracting widespread societal concern. In this study, we systematically applied multivariate statistical analysis, geostatistical methods, and the positive matrix factorization (PMF) source apportionment technique to elucidate the sources and contributions of eight heavy metals (Cd, Hg, As, Pb, Cr, Cu, Zn, Ni) in farmland soils within an industrialized town. Our findings reveal that Cd, Hg, Pb, and Zn exhibit pollution or enrichment in farmland soils compared to natural background levels, with Hg and Cd surpassing 164.3% and 50.2%, respectively. Notably, Zn demonstrates discernible point-source pollution. Source apportionment results highlight industrial point sources, coal combustion, and agriculture as the primary anthropogenic contributors to heavy metal contamination, with zinc-plating enterprises being the predominant industrial point sources. Addressing the specific issue of point-source pollution from Zn in industrial activities, further analysis establishes a correlation between soil Zn content and the distance from zinc-plating enterprises. Utilizing an atmospheric transport model, we observe that the impact of industrial activities on soil Zn is limited when the distance exceeds 1.5 km, emphasizing the importance of monitoring Zn pollution within areas less than 1.5 km. This study pioneers a progressive source apportionment approach, considering the origins of different heavy metals, pollution levels, distance factors, and the cost-effectiveness of environmental measures. The insights gained provide scientifically sound strategies for future decision making in environmental protection.

“…Soil, as a fundamental component of our ecosystem, plays a crucial role in human survival and development (Fei et al, 2020). However, in recent years, the rapid socio-economic growth driven by industrialization, urbanization, and intensi ed agriculture has led to the increased release of heavy metals (HMs) into soil ecosystems (Safari and Delavar, 2019;Wu et al, 2021;Xue et al, 2019). The ubiquity, toxicity, and persistence of these HMs have raised concerns about their escalating concentrations in soil, which are believed to pose ecological and human health risks (Fei et al, 2023;Sun et al, 2021;Yang et al, 2022a).…”

To conduct a precise health risk assessment of heavy metals (HMs) in soil, it is imperative to ascertain the primary sources of potential health risks. To achieve this objective, we conducted comprehensive measurements of HMs, including Al, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Sb, Ti, V, and Zn, in soil extracted from the polymetallic mining area. A method combining the positive matrix factorization with the health risk assessment model was used to quantify the source-specific health risks. Results indicate that when compared to the local background values, the accumulation of Cd, Cr, Cu, Mn, Pb, Sb, and Zn in the local soil appears to be influenced by anthropogenic activities. Among these sources, local industrial-related activities contributed the largest proportion of HMs to the soil at 34.7%, followed by natural sources at 28.7%, mining and metallurgy-related activities at 28.2%, and traffic-related activities at 8.40%. Although the non-carcinogenic and carcinogenic risks associated with individual heavy metal elements were found to be below safety thresholds, the cumulative health risks stemming from total heavy metals exceeded safety limits for children. Moreover, the unacceptable health risks for children originating from industrial-related activities, natural sources, and mining and metallurgy-related activities were primarily concentrated in proximity to mining sites and industrial areas within the local region. This investigation furnishes valuable insights that can aid governmental authorities in formulating precise control policies to mitigate health threats posed by soils in polymetallic mining areas.
