“…We found that the HQ and HI values obtained in the present study are significantly higher than those previously reported for this area by Zhuo et al (2020) [14], Liu et al (2021) [68], and Hua et al (2022) [69], which we suspect could be attributed to our grid-intensive soil sampling across the entire region, rather than assessments based on sporadic soil sampling. [69], which we suspect could be attributed to our grid-intensive soil sampling across the entire region, rather than assessments based on sporadic soil sampling. Given that As and Cd have high toxicity coefficients, they are often used to calculate carcinogenic risk [26,70].…”

This study collected 1135 topsoil samples of cultivated land in Laiyang County, eastern China, to analyze the distribution, pollution and health risks of heavy metals (As, Cd, Cu, Cr, Hg, Ni, Pb and Zn). The results show that: (1) the levels of eight heavy metals at some sites were higher than the risk screening values in China, and there was heavy metal pollution. (2) An improved geoaccumulation index was used to evaluate soil pollution. The average value of Igeo before and after improvement was 0.32 (Iml, no pollution to medium pollution) and −0.04 (Iol, no pollution), respectively. (3) Hg and Cd were identified as the main contributors to ecological risk in this study, with a cumulative ecological risk contribution percentage > 65%. The results of the potential ecological risk index (PERI) show that 9.3% of the sampling sites were considered to have moderate ecological risk. (4) As, Pb, Ni and Cu made a contribution of >95% in terms of non-carcinogenic risk to adults and children through different exposure routes, and different soil intake routes posed no non-carcinogenic risk to adults; there was a sampling site with HQChildren > 1, which was consistent with the non-carcinogenic risk site, indicating that children in this location and surrounding areas are more likely to face dual health risks. Therefore, it is necessary to promote the risk management of heavy metals in the study area in order to safely use soil resources.

“…Cd is closely related to phosphate fertilizers along with TP [2,7,11,91], and phosphate fertilizers are known to contain high concentrations of Cd [10,92,93]. Furthermore, the accumulation of phosphorus in soil is associated with intensive livestock production [11,14].…”

“…In contrast, Cr and Ni are known to be influenced by natural sources because they depend on the parent rock [2,70,96,97]. Al is also a main component of the earth's crust and has been mainly used as a reference element [98,99].…”

“…Agricultural soils play an essential role both in the ecosystem and as the basis for food production. However, they have recently been exposed to various pollutants such as heavy metals (HMs) and phosphorus owing to the rise in industrial development and agricultural activities [1][2][3][4][5][6]. In particular, the use of fertilizers, for increasing crop production in agricultural soils, and pesticides have generated concerns regarding the accumulation of phosphorus and HMs [7][8][9][10][11].…”

“…For example, various citrus, apple, grape, and avocado orchards have experienced an increase in Cu concentration in the soil when using Cu-based products (e.g., CuSO 4 , CuO, Bordeaux mixture) [22][23][24][25][26][27]. HMs accumulated in soil via these agricultural activities exhibit low solubility and are considered potentially toxic, causing various cancers and kidney function disorders in humans when they enter the food chain or through direct contact [2,[28][29][30][31][32].…”

This study investigated the accumulation of total phosphorus (TP) and heavy metals (HMs; Pb, Zn, Cu, Cd, Cr, and Ni) in citrus orchard soils in Jeju Island, Korea, identifying potential soil pollution sources using statistical analysis. Anthropogenic HM pollution was evaluated using the geoaccumulation index and enrichment factors, whereas HM bioavailability was assessed via single extraction. TP, Zn, Cu, and Cr concentrations in citrus orchard topsoil were significantly higher than those in forestland soils, indicating their accumulation in the surface layer. Statistical analyses confirmed that elements with high concentrations were closely related to potential pollution sources accumulated on the surface layer of citrus orchards owing to agricultural activities. Particularly, Zn and Cu accumulation was confirmed to originate from intensive compost and pesticide use in citrus orchards. Cu showed the highest contamination and enrichment of all HMs. However, Zn and Cu fractions, determined via an availability assessment, were dominated by acid or complex compounds, indicating that labile Zn and Cu have potential bioavailability for plants. Nevertheless, their fractions accounted for a small proportion (mean < 15%). Therefore, despite the high pollution levels of Zn and Cu, their availabilities were extremely low, indicating a negligible bioavailability in crops and no impact on aquatic ecosystems.
