“…The assessment of HM pollution status and the comprehensive pollution degree of soil and water resources in the study area utilized screening values from GB 15618-2018 China's "Soil Environmental Quality Construction Land Soil Pollution Risk Control Standard" [39], in conjunction with the single-factor pollution index (P i ) [40][41][42] and Nemerow pollution index (P N ) [43][44][45][46]. Specific values are detailed in Tables S2 and S3.…”

Understanding the contamination and sources of heavy metal(loid)s (HMs) at historical sites is vital for safeguarding human health and the ecological environment. This study focused on As, Hg, Cd, Cu, Pb, Ni, and Cr concentrations in the residual soil, groundwater, and surface water around a mineral processing plant. The sources of these elements and the human health risks posed by them were evaluated using various indexes. Soil HM concentrations exceeded background values for Yunnan Province, ranked as As > Pb > Cd > Cu > Hg > Ni. The river water met China's Class II waterbody standard; however, Cd, Cu, Pb, and pH exceeded the maximum permissible sewage discharge concentrations in the accumulated water. The groundwater showed severe HM pollution, meeting China's Class III water quality standard. The average value of the Nemerow pollution index was consistent with that of the single-factor pollution index in the following order: As > Pb > Cd > Ni > Cu > Hg. Children face heightened risk through the oral ingestion of As, Cd, and Pb, particularly in high-value sampling points in the residue deposit area. The main sources of these pollutants are anthropogenic activities and the soil formation matrix.

“…Power generation and transmission are two of the major causes of cancer in humans [12,13]. Reports have shown that power transmission and distribution activities can elevate the concentrations of metals in the environment [14][15][16][17][18]. Metals such as aluminum (Al), copper (Cu), iron (Fe), cadmium (Cd), and lead (Pb) are closely associated with power transmission and distribution, hence, the environment could be contaminated by these metals over time.…”

The generation, transmission, and distribution of power have both positive and negative effects. However, this has not been effectively assessed and documented in the study area. Hence, this research was conducted to assess the impact of power transmission and distribution activities on the levels of trace metals in soil, including Telfairia occidentalis (T. occidentalis). In this research, topsoil and T. occidentalis were obtained from the vicinity with high tension copper cables at Ikono, Ibiono Ibom, Itu, Uyo, and Uruan in Akwa Ibom State. Similar samples were obtained 100 m away from areas with high-tension copper cables and used as controls. The mean values (mg kg-1) of cadmium(Cd), copper (Cu), iron (Fe), and lead (Pb) obtained in soil were 2.13 ± 1.24, 43.52 ± 9.28, 1,265.84 ± 287.33, and 27.39± 5.66, respectively. Whereas, the mean concentrations (mg kg-1) of these metals in T. occidentalis were 0.17 ± 0.10, 12.98 ± 2.50, 217.81 ± 62.56, and 1.47 ± 1.40, respectively. The results obtained revealed that the mean concentrations of Cd, Cu, and Fe in soil were higher than their recommended safe limits, while the mean concentrations of Cu, Fe, and Pb in T. occidentalis exceeded the limits. The results indicated that the mean concentrations of all metals in the impacted soils were higher than in the control plot for both soil and T. occidentalis. Pollution models employed showed that soils and T. occidentalis from the studied locations were highly impacted by metals originating mainly from power transmission and distribution activities. The estimated daily intake rate of all the metals through soils and T. occidentalis was investigated for the children and adult groups within their recommended oral reference doses except for Cd. The non-cancerous risks for the children and adult groups for both soil and T. occidentalis were less than than 1 mg kg-1 day-1. However, the children’s class was more susceptible. Cancer risks for both the children and adult groups via soil and T. occidentalis were within the acceptable limit, but the entire cancer risk for the children via T. occidentalis from the Uyo vicinity was higher than the safe limit. This study revealed the effects of power transmission and distribution activities on the metal loads in soil and T. occidentalis and the related human health problems. Consequently, consistent exposure to soil particles impacted by high-tension cables and the cultivation of edible plants under high-tension cables should be avoided.
