“…The geo-accumulation index (Igeo) is a quantitative method used to assess the enrichment of trace elements in soil. It achieves this by comparing the ratio of measured values to background values in the soil environment [ 27 , 28 ]. The formula used to calculate it is as follows:

“…In particular, heavy metal pollution in soil has attracted extensive attention all over the world (Lokeshwari and Chandrappa, 2006;Cao et al, 2010;Akbarpour et al, 2021). Heavy metal pollution in soil has the characteristics of a wide range and long duration (Hu et al, 2018;Chen et al, 2021). These pollutants can become enriched in soil and migrate to the human body through the food chain, posing a potential threat to the natural ecosystem and public health (Burges et al, 2015;Zhang et al, 2017;Li et al, 2019).…”

“…It is important to provide information about various heavy metal pollution levels in the soil to guide the formulation of relevant pollution control policies (Solomon et al, 2016). To assess the risk of heavy metals in soil, soil pollution sources have attracted the attention of many researchers (Chen et al, 2021;Yao et al, 2021). There are many indicators of heavy metal pollution in soil, including the enrichment coefficient (Buat-Menard and Chesselet, 1979), the pollution index (Wei and Yang, 2010), the Nemerow comprehensive pollution index (Cheng et al, 2007), the geological accumulation index (Hasan et al, 2013), and the potential ecological risk index (Sun et al, 2010).…”

The distribution of heavy metals in topsoil can have a significant impact on human health. A total of 1, 556 samples were collected from the topsoil of Weifang, China. Various indices, including the pollution index (PI), the Nemerow integrated pollution index (PN), and the potential ecological risk index (RI), were used to analyze the heavy metal pollution levels. The sources of heavy metals were analyzed using the positive matrix factorization (PMF) model. The results are as follows: (1) the ecological risk level of Cu, Pb, Zn, Ni, Cr, and As in the study area is relatively safe, but the ecological risk level of Cd and Hg is relatively high, leading to an increase in the ecological risk level of heavy metals in the study area and (2) the PMF results show that there are six main sources of the eight heavy metals. Cr and Ni come from soil parent material and nonferrous metal industrial activities; As is closely related to fossil fuel (coal)-related industrial activities; Cu originated from diesel fuel-related transportation and agricultural machinery activities; Pb is derived from gasoline transportation activities; Hg is closely related to the application of pesticides in agricultural production; Cd and Zn originated from organic fertilizers used in agricultural activities.

“…At present, there are many methods to evaluate soil heavy metal pollution, among which the index method is the most common, such as nemero comprehensive pollution index [19], enrichment factor [20], meta-analysis [21], geoaccumulation index [22][23][24] and potential ecological hazard index [25][26][27]. Thus, a comprehensive evaluation method is urgently needed.…”

In the process of industrial production, the flue gas discharged from the chimneys adjacent to the farmland often contains some heavy metal elements, which enter the soil by atmospheric deposition, resulting in long-term accumulation of some heavy metal elements in the soil exceeding the standard. The paper reports the spatial distribution and risk assessment of soil heavy metals in suburban soil from the interior area of Ningyuanbu Town in Jinchuan District, China. Forty-one soil samples were obtained from a depth of 0-40 cm or 0-100 cm using a wooden shovel to analyze the concentrations of heavy metals (Zinc, Copper, Nickel, Lead, Cadmium, Chromium, Arsenic and Mercury) by ICP-MS. The results showed that the Zn, Cu, Pb, Ni, As, Hg and Cd were mainly distributed in the soil layers of 0-60 cm, and there was a point of inflection at a depth of 60 cm, it basically showed a uniform distribution below the inflection point, but the Cr in the soil layers of 0-100 cm was distributed uniformly. Based on the assessment of the risk screening values and geo-accumulation index, it was found that Cu and Ni surpassed the standard value. According to the index of potential ecological risk (RI), the average value of RI was 323.71 in the soil layers of 0-20 cm and it belong to severe contamination, and the average value of RI was 236.36 in the soil layers of 20-40 cm and it belonged to moderate contamination, and more attention must be paid to Cu and Ni in farmland soils in these areas. Therefore, the study area should be divided into safe utilization category and priority protection category. The input of pollution sources should be strictly controlled for the priority protection category, for instance, alternative planting, fallow and rotating should be implemented to reduce the transfer of heavy metals to crops and reduce the risk of food safety and health.
