“…They are also identical with the exceeded Cd limit values in the surface layer in all monitored arable soils (except autumn 2019 at Locality I). Our results also confirm the conclusions of the authors Yuanan et al [87]; in general, the heavy metals in the soil's surface layers indicate the impact of human activity. Soil contamination by Cd can be caused by, amongst other reasons, the use of large amounts of inorganic fertilizers, mainly phosphorus fertilizers [88][89][90][91], and also agrochemicals [44], which were also used in the localities we monitored.…”

“…The correlation of Cd with other heavy metals may have a mixed source (e.g., lithogenic and anthropogenic) or different geochemical properties from other heavy metals in the soil, as reported by Chai et al [102]. The authors Yuanan et al [87] stated that, in general, high values of the correlation coefficients between the contents of the heavy metals are likely to contribute to the same or closely related sources. The contents of the heavy metals Cu, Pb, and Zn, can be interconnected and are probably partially influenced by biological factors, the content of organic substances in the soil, and/or pollution [104].…”

This study assisted in identifying and preventing the increase in heavy metals in soil and winter wheat. Its accumulation can affect cultivated crops, quality and crop yields, and consumers’ health. Selected heavy metals were analyzed using the GTAAS method. They were undertaken on selected heavy metals content (Cd, Cu, Pb, and Zn) in arable soils at three sites in Slovakia and their accumulation in parts of cultivated winter wheat. Our study showed that the limit value of Cd in soil samples was exceeded in the monitored arable soils from 2017–2019. The average content values of Cu and Zn did not exceed the limit values, even in Pb values (except for the spring period). The analyses also showed that the heavy metals content for plants bioavailable in soil did not exceed the statutory critical values for Cd, Cu, and Zn’s average content values. However, Pb content exceeded permitted critical values. Heavy metals bioaccumulation (Zn, Cu) was within the limit values in wheat. Analyzed Cd content in wheat roots and Pb content were determined in all parts of wheat except grain. The study showed that grain from cultivated winter wheat in monitored arable soils is not a risk for consumers.

“…It has been proved that heavy metal accumulation in soil differs by soil texture, physical properties, and chemical properties [7]. Additionally, ecological processes such as biological metabolism and surface runoff and human activity, such as industrial emission, waste pollution, agricultural pollution, and traffic emission particles, can affect heavy metal accumulation in soil [8,9]. Heavy metals in the roadside agricultural soil are more likely to be linked to complex human activities.…”

The agricultural soil alongside highways has experienced multiple potential ecological risks from human activities. In this study, 100 soil samples near the highways were collected in Lishui District, Nanjing City. Using the single-factor pollution index, the Nemerow comprehensive pollution index, and the potential ecological risk index, the study investigated the heavy metal contents and distribution in roadside agricultural soil. PCA and a multiple regression model were applied to quantitatively analyze the spatial relationships between sampling soil heavy metal accumulation and the surrounding man-made landscape. The mean contents of Cu and Pb exceeded the background, while Cd, Cr, and Zn were lower than that. The potential ecological risk index exhibited a very low ecological hazard and only Cr in soils rarely showed moderate risk. Furthermore, quantitative analysis for the sources of contamination revealed that agricultural practices were the dominant contributors to the heavy metals, including Cd, Cu, and Zn, while road and heavy industrial practices contributed to Cr and Pb. The study provides sources of heavy metal pollution from human activities in roadside agricultural land and serves as a reference for ecological restoration.

“…And other health problems such as stomach and heart diseases, hypertension, and anorexia (Qian et al 2020). Chronic PTEs toxicity has adverse effects on human health, such as lung disease, renal failure, bone fracture, and may lead to hypertension, fertility and hormonal, immune, liver function, and endocrine system deficiency (Yuanan et al 2020). To understand this kind of threat, it is important to evaluate the surface and groundwater quality by means of PTEs distribution in disaster prone mining and non-mining areas and their associated health risk.…”

Accelerated mining activities have increased water contamination with potentially toxic elements (PTEs) and their associated human health risk in developing countries. The current study investigated the distribution of PTEs, their potential sources and health risk assessment in both ground and surface water sources in mining and non–mining areas of Khyber Pakhtunkhwa, Pakistan. Water samples (n=150) were taken from selected sites and were analyzed for six PTEs (Ni, Cr, Zn, Cu, Pb and Mn). Among PTEs, Cr showed high mean concentration (497) μg L–1, followed by Zn (414) μg L–1 in mining area, while Zn showed lowest mean value (4.44) μg L–1 in non-mining areas. Elevated concentrations of Ni, Cr and moderate level of Pb in ground and surface water of Mohmand District exceeded the permissible limits set by WHO (2017). Multivariate statistical analyses showed that pollution sources of PTEs were mainly from mafic-ultramafic rocks, acid mine drainage, open dumping of mine-wastes and mine tailings. The hazard quotient (HQ) was highest for children relatively to adults, but not higher than the US-EPA limits. The hazard index (HI) for ingestions of all selected PTEs were lower than the threshold value (HIing <1), except Mohmand District which showed (HI >1) in mining areas through ingestion. Moreover, the carcinogenic risk (CR) values exceeded the threshold limits for Ni and Cr set by the US-EPA (1.0E−04 to 1.0E−06). In order to protect the drinking water sources of the study areas from more contamination, the management techniques and policy for mining operations need to be implemented.
