“…This showed that ingestion was the predominant exposure route for PTEs affecting human health, followed by inhalation and skin contact, which was the least. These results were also reported by previous studies [ 59 ]. The non-carcinogenic risks of PTEs in adults and children were in the order of As > Cr > Pb > Ni > Hg > Cu > Zn > Cd.…”

The accumulation of potentially toxic elements (PTEs) in agricultural soils is of particular concern in China, while its status, ecological risks, and human health hazards have been little studied in the permafrost areas of Northeast China. In this study, 75 agricultural soil samples (0–20 cm) were collected from the Arctic Village, Mo’he City, in the northernmost part of China. The average concentration (mean ± standard deviation) of As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn were 12.11 ± 3.66 mg/kg, 0.11 ± 0.08 mg/kg, 52.50 ± 8.83 mg/kg, 12.08 ± 5.12 mg/kg, 0.05 ± 0.02 mg/kg, 14.90 ± 5.35 mg/kg, 22.38 ± 3.04 mg/kg, and 68.07 ± 22.71 mg/kg, respectively. Correlation analysis, cluster analysis, and principal component analysis indicated that As, Cu, Ni, and Zn likely originated from geogenic processes, Hg and Pb from long-range atmospheric transport, Cd from planting activities, and Cr from Holocene alluvium. The geo-accumulation index and enrichment factor showed that As, Cd, Hg, and Zn are enriched in soils. The Nemerow pollution index showed that 66.67%, 24%, and 1.33% of soil samples were in slight, moderate, and heavy pollution levels, respectively, with Hg being the most important element affecting the comprehensive pollution index. The potential ecological risk index showed that 48.00% and 1.33% of soil samples were in the moderate ecological risk and high potential ecological risk levels, respectively. The non-carcinogenic and carcinogenic human health risk index for adults and children were both less than 1, which was within the acceptable range. This study revealed the accumulation pattern of PTEs in agricultural soils of permafrost regions and provided a scientific basis for research on ecological security and human health.

“…With the rapid development of rural industrialization in China, the farmland soil in some areas has been polluted by heavy metals to varying degrees [24]. The content of heavy metals in the soil of Qianjin town has accumulated to a certain extent, which is greater than that in 2010 and more than that in 2008.…”

In order to study the pollution, ecological risk and health risk of heavy metals and risk elements in the surface farmland of the cold black soil area in Northeast China, the main grain production area in China, based on the collection and analysis of samples in 2010 and 2021, the soil heavy metals and risk element in this area were assessed by using the method of Geo accumulation index (Igeo), potential ecological hazard index (RI) and health risk assessment (HRA) model. The results show that there are heavy metals and risk element pollution in the soil, which is accumulated year by year. The average contents of Hg, Cd, Cr, Ni, Pb, Zn, As and Cu in the soil in this area are higher than the background values of Qianjin town. The heavy metals and risk element in the black soil and farmland in the cold area are obviously affected by human activities. There are different degrees of regional variability, and the coefficient of variation of Hg is 79%; Some elements have ecological risk, and Hg and Cd are the main influencing elements of soil ecological risk in shallow farmland; Heavy metals and risk element have non-carcinogenic health risks to children. The carcinogenic risk index of adults and children exceeded the soil treatment benchmark value of 10 -6 proposed by EPA, As is the element that contributes the most to non-carcinogenic health risk and carcinogenic health risk in adults and children. In view of the continuous accumulation of heavy metals and risk element in farmland soil, it is necessary to improve ideological understanding, improve laws and regulations, formulate norms

In order to understand the pollution status of potentially toxic elements (Hg, Cd, Cr, Ni, Pb, Zn, As, and Cu) in the surface farmland soil of black soil in Northeast China and its impact on human health, Hailun City, a representative area of black soil in Northeast China, was selected as the study area. The pollution degree, ecological risk, and health risk of soil and potentially toxic elements in this area were evaluated by the index of geoaccumulation method (Igeo), the potential ecological hazard index method (RI), and the health risk assessment model (HRA). The results showed that the average contents of eight potentially toxic elements in the soil in this area were higher than the soil background value in Hailun City, showing different degrees of accumulation. There are Cd and Hg pollution and ecological risks in the soil of Hailun City. Cd has slight, medium, strong, and extremely strong ecological risks, and the risk index ranges from 19.32 to 751.64; Hg takes second place. Children are more vulnerable to the health threat of potentially toxic elements, and oral intake is the main source of soil exposure risk. The potentially toxic elements As and Cr are more likely to cause human health risks.
