“…A comprehensive assessment of heavy metal contamination and subsequent risks for ecosystems and humans is necessary to develop management measures, reduce soil insecurity, and handle climate change (Kumar et al 2019 ; Lian et al 2022 ). Additionally, large quantities of Egyptian tomatoes are shipped to other nations throughout the world.…”

Heavy metal contamination of food crop plants is viewed as a global issue. Heavy metals like cadmium (Cd), copper (Cu), lead (Pb), chromium (Cr), zinc (Zn), nickel (Ni), arsenic (As), cobalt (Co), and mercury (Hg) are poisonous. Depending on their concentration and capacity for bioaccumulation, they can provide a range of health risks.This research sought to investigate the effects of toxic metals (TMs) on the growth characteristics of produced tomatoes grown under wastewater irrigation. Additionally, it looked into the potential repercussions of both domestic and foreign individuals consuming this plant. In south Cairo, Egypt, two study locations were looked into: a control site in Abu Ragwan, which received water from tributaries of the Nile River, and a contaminated site in El-Shobak El-Sharky, which had raw industrial wastewater. The nutrients of soil and tomato plants (N, P, and K) decreased (P < 0.01), while TMs increased (P < 0.001) significantly as a result of using wastewater for irrigation. Except for Cu, all examined TM accumulating in tomato plants’ roots as opposed to shoots had a bioaccumulation factor (BF) > 1. However, the tomato plant’s shoot had solely undergone Pb and Ni translocation and storage, with a translocation factor (TF) > 1. A significant amount of Fe (5000.1 mg kg−1), Pb (360.7 mg kg−1), and Mn (356.3 mg kg−1) were present in the edible fruits. The ingestion of contaminated crops increases the daily intake rate of metals (DIR). The values of the high hazard quotient (HQ) were obtained (2073.8 and 2558.9 for Pb, 574.0 and 708.3 for Cd, and 41.1 and 50.7 for Fe for adults and children, respectively). Therefore, tomato plants grown in soils irrigated with untreated wastewater may offer a greater danger to human health, indicating that they should not be grown as a crop for human consumption.

“…The contributions of Cd and Cu were 19.5% and 14.01%, respectively, ranking second in their respective total percentages. The content of Cd in phosphate fertilizers ranges from 9 to 100 mg kg −1 (Lian et al, 2022), and Cd is present in organic and N fertilizers. The correlation analysis showed a highly significant positive correlation between SOM, Se, and N ( p < 0.01), while most SOM and Se values were homologous with N. Combining the correlation and PCAs, several factors with higher contributions to PMF1 were homologous, so it can be judged that PMF1 is related to agricultural material.…”

The present study investigates heavy metal pollution and its sources in cultivated soils in Bijie City, Guizhou Province, China. The ground accumulation index method was used to evaluate the associated risks, while correlation, principal component, and positive matrix factor model analyses were used to identify sources. The results show that the overall contamination levels, except for Cd, were not serious. Agricultural materials, industrial activities, transportation, coal combustion and atmospheric deposition, parent rock, and irrigation accounted for 19.66%, 14.11%, 14.54%, 16.33%, 20.70%, and 14.67% of the total accumulation of metals, respectively. Copper, Ni, Zn, and Cr came mainly from parent rocks; Pb was mainly from traffic emissions; Hg was mainly from coal deposition; As was mainly from irrigation; and Cd was mainly from industrial activities. The main sources of soil metals were irrigation, agricultural activities, and coal deposition in the east and industrial activities and soil-forming parent rocks in the west.

“…Anthropogenic emissions are a significant contributor to point source pollution in cultivated soils. [ 5 ] Inappropriate farming practices, such as utilizing wastewater for irrigation and applying fertilizers and compost improperly, play a crucial role in the contamination of agricultural soils with metals and affect the distribution of metals therein.

“…[ 1,2 ] Long‐term presence of toxic metals in farmland can diminish soil productivity, impair crop yields, and pose potential health risks to humans through the food chain and exposure to soil pollution. [ 3,4,5 ] Generally, excessive toxic metals in agricultural soil mainly originated from anthropogenic activities, such as metal smelting, mining, sewage irrigation, and the overuse of metal‐containing fertilizers and pesticides. [ 6,7 ] These human activities result in a sharp increase in metal pollution on local, regional, and even global scales.…”

Metals in soils exert toxic effects on soil quality and human health. In order to carry out metal contamination assessment and human health risk assessment of agricultural soils, a total of 662 cultivated soil samples were collected from two industrially oriented towns and three agriculturally oriented towns of Shifang City, Southwest China. Various indices were applied to analyze the pollution levels of soils caused by metals (Cr, Fe, Pb, Sr, Ti, V, Zn, and Zr). The relatively high values of the geo‐accumulation index (Igeo) and the enrichment factor (EF) suggested that Sr, V, and Zn had cumulative trends in the soils. The average pollution load index (PLI) values of the industrial towns (1.19 and 0.99) were higher than those of the agricultural towns (0.92, 0.53, and 0.43), demonstrating the contribution of industrial activities to soil metal enrichment. The health risk assessment from the five towns indicated that Cr and V were the dominant contaminants in soils with high potential health risks. Dermal contact was the major pathway of the exposure of children and adults to Cr and V. This study improved the understanding of the pollution levels of metals in Shifang agricultural soils and put forward the necessity of minimizing the health risk of Cr and V in agricultural soil.
