“…Table 2 indicates that available concentrations of the studied trace elements within different soil locations and depths significantly correlated with their corresponding total contents in soil. Probably, the alkaline pH range of the studied soils increased TEs precipitations and accumulations (Hale et al, 2012;Kluge et al, 2018;Dotaniya et al, 2020). As mentioned above, such available concentrations of TEs were significantly correlated with TEs contents in well waters.…”

“…30-60 cm and 60-120 cm. This is probably because Pb accumulated at higher concentrations in the surface soil layers (Dotaniya et al, 2020) mainly in the form of lead phosphate (Gao et al, 2020) due to extensive fertilization with P-fertilizers (Valipour et al, 2016). Moreover, this area is also near Ismailia-El-Zagazig highway.Thus, aerosol depositions might also enrich soils with Pb (Hashim et al, 2017) and Cu (El-Khatib et al,2020) and the later element deposits in soils with relatively high mobile fractions (Zhou et al, 2020).…”

N ILE Delta aquifer is one of the largest aquifers worldwide that receives the agrochemical leachates from the surrounding environments. To assess the status of some trace-elements (As, Co, Cd, Pb, Cu and Ni) in the NorthEast area of Egypt, well-water samples beside of surface, subsurface and deep-soil-samples were collected from 17 different locations to represent three environmental-pathways: the first one signifies areas relatively nearby Damiettabranch, while the third pathway stands for the arable lands nearby Ismaellia-canal. The second pathway is in-between these two pathways. Furthermore,a reference soil (irrigated with fresh-Nile-water) was sampled for data comparison.These samples were estimated for their total and AB-DTPA-extractable contents of the aforementioned trace elements (TEs). Results revealed that AB-DTPA-extractable-TEs were in dynamic equilibrium with the corresponding soluble contents in irrigation water. Likewise, AB-DTPA-extractable-TEs significantly correlated with their corresponding total contents in soil. Concentrations of TEs in surface-soil-layer were higher than the corresponding ones in the subsurface and deep-soil-layers. The calculated values of contamination factor indicated moderate to very high levels of soil contamination with TEs. According to the principal component analysis, total and AB-DTPA-extractable-TEs in soil were affected by only one-principal-component, recording 86.13 % of the data variance. This indicates that these contaminants originated probably from the same source. Moreover, multivariate-analyses revealed that total TEs significantly and positively correlated with soil hydraulic conductivity and bulk density, while negatively correlated with exchangeable sodium percentage, clay and organic matter contents. These results indicate that the groundwater flow is the potential source that enriched soils with TEs. Accordingly, any reductions in effluents of fresh Nile water, which is in hydraulic continuity with the groundwater in the studied area, can increase the severity of soil pollution with TEs in the studied area.

“…The main source of Pb contamination in the soil is its geogenic contribution, which reduces the soil microbial activities. The effects of Pb on soil are several, such as reducing soil nutrients, microbial diversity, and soil fertility [73]. Furthermore, earthworms (Eisenia fetida) are usually affected by Pb toxicity, which may cause earthworm mortality.…”

Environmental problems have always received immense attention from scientists. Toxicants pollution is a critical environmental concern that has posed serious threats to human health and agricultural production. Heavy metals and pesticides are top of the list of environmental toxicants endangering nature. This review focuses on the toxic effect of heavy metals (cadmium (Cd), lead (Pb), copper (Cu), and zinc (Zn)) and pesticides (insecticides, herbicides, and fungicides) adversely influencing the agricultural ecosystem (plant and soil) and human health. Furthermore, heavy metals accumulation and pesticide residues in soils and plants have been discussed in detail. In addition, the characteristics of contaminated soil and plant physiological parameters have been reviewed. Moreover, human diseases caused by exposure to heavy metals and pesticides were also reported. The bioaccumulation, mechanism of action, and transmission pathways of both heavy metals and pesticides are emphasized. In addition, the bioavailability in soil and plant uptake of these contaminants has also been considered. Meanwhile, the synergistic and antagonistic interactions between heavy metals and pesticides and their combined toxic effects have been discussed. Previous relevant studies are included to cover all aspects of this review. The information in this review provides deep insights into the understanding of environmental toxicants and their hazardous effects.

“…A human health hazard is closely linked to the intake of metal(loid)s-contaminated food crops. Excess Pb levels in the human body cause neurological and cardiovascular effects in humans, especially children (Dotaniya et al 2020;Manisalidis et al 2020). Health risk effects due to As exposure range from acute to chronic effects, including cancer, hyperkeratosis, melanosis, peripheral vascular diseases, lung diseases, and hypertension.…”

Soil to plant metal(loid) accumulation has been highly evaluated in recent years due to its significant impact on human health. This study reports the concentrations of 15 metal(loid)s in four vegetables (tomato, onion, chili, and lettuce) cultivated in one greenhouse, one top garden, and two roof gardens, rooftop urban gardens in four locations within the metropolitan area of Mexico City. In this experiment, the contribution of metals and metalloids due to atmospheric deposition and irrigation may be negligible. It is considered that the concentration of metals depends only on transfer from the soil. Soil analysis indicates that only vanadium in one location (a rooftop garden in V. Carranza) exceeds the permissible limits recommended by the Mexican government. For most metals, lettuce shows the highest concentrations and transfer factors compared to the other vegetables studied. The transfer factors were exceptionally high for Cd (lettuce) and Hg (tomato), presenting values above 1. The concentrations of As, Cd, Hg, and Pb were compared with permissible limit values recommended for vegetables by different international agencies. It was observed that, except for As, these values are exceeded in various vegetables harvested in this study. This information must be corroborated with more detailed studies evaluating the chemical species in which those metal(loid)s is present and identifying the physicochemical parameters of the soil that caused the enrichment of these metal(loid)s to exceed the permissible limit values.
