“…Well Hakanson's ecological hazard index method is a widely recognized quantitative ecological risk assessment index, taking into account not only the concentration but also the toxicity of heavy metals (Hakanson, 1980 ). Although first put forward in 1980, the index is still in use today (Long et al, 2021 ; Mohammadi et al, 2020 ). The formulas are as follows: …”

As medicinal plants can accumulate harmful metals from the native soil, people's consumption of these materials may cause the human body to accumulate toxic metal elements. This has given rise to people’s concerns about the quality and safety of Chinese medicinal materials. This research aims to determine the levels of Cr, Ni, Cu, Zn, As, Cd, Hg and Pb in four medicinal plant species ( Aster tataricus L.f., Salvia miltiorrhiza Bge , Radix Aucklandiae, Scutellaria baicalensis Georgi ) and their native soil. All samples were collected from Qian’an city, beside Yanshan Mountain Range in Tangshan city, east Hebei Province, north China. The contents of heavy metals we detected in the soil conformed to the current limits. However, the Cd and Hg in the soil had a very high potential ecological risk because of their contents higher than the base level of local soil. The contents of Cu, Cd, Hg and Pb in some medicinal herbs exceeded the standards. The content of Cu in Radix Aucklandiae exceeded the standard by 3 times, and others exceeded the standard by less than one time. The comprehensive health risk assessment of heavy metals with chronic non-carcinogenic effects for human body showed that none of the four medicinal herbs can create a health risk. Thus, there is no strong positive correlation between heavy metal pollution in medicinal herbs and that in the native soil. Further research should be investigated to the connection between the heavy metal levels in the soil and plants, and the comprehensive effects of soil, air and irrigation water on heavy metal pollution of Chinese herbal medicines. We also recommend that Chinese herbal medicines should be cultivated and gathered only from controlled or uncontaminated areas.

To explore the characteristics of heavy metal pollution in farmland soils in the Jiefangzha Irrigation Area of the Hetao Irrigation District, Inner Mongolia, 60 samples of the surface soil (0–20 cm) of the irrigation area were collected to detect and analyze the content of the typical heavy metal elements Cu, As, and Pb in the soil. The methods utilized included the single factor index method, the Nemerow index method, the geological accumulation index method, and the potential ecological hazard index method to evaluate their pollution and ecological risks, and these were combined with geostatistical methods using GIS technology to quantitatively analyze their spatial distribution characteristics. The results showed that the average content of Cu, As, and Pb did not exceed the background values in the Hetao Irrigation Area, and the contents showed a moderate variation, with the order of variation as As>Cu>Pb. The multivariate statistical analysis results showed that the three elements, Cu, As, and Pb, had similar sources, being primarily the use of agrochemicals, such as fertilizers and pesticides. The semi-variance function model fitting results showed that Pb was a spherical model, and Cu and As were Gaussian models. The Kriging interpolation showed that the contents of As, Pb, and Cu, in general, showed a trend that was higher in the northwest and lower in the southeast, with a change of gradient increasing from the southeast to the northwest. Human activities were the primary factors that were causing the distribution difference.

“…Some metals like As, Cr, Pb, Cd, Hg, and U are very toxic even at low concentrations. Heavy metals in the soil and water may come from natural (volcanic eruption and sedimentation) and anthropogenic sources (ore melting, smelting, mining, overuse of fertilizers, pesticides, and sewage sludge) (Ayangbenro & Babalola, 2017; Gabarrón et al, 2017; Long et al, 2021). Sources of heavy metals that accumulate in the soil through natural and anthropogenic activities are summarized in Table 1.…”

Heavy metal pollution in soil and water is a potential threat to human health as it renders food quality substandard. Different biosorbents such as microbial and agricultural biomass have been exploited for heavy metal immobilization in soil and sorptive removal in waters. Biosorption is an effective and sustainable method for heavy metal removal in soil and water, but the inherent challenges are to find cheap, selective, robust, and cost‐effective bioadsorbents. Microbial and agricultural biomass and their modified forms such as nanocomposites and carbonaceous materials (viz., biochar, nanobiochar, biocarbon), might be useful for sequestration of heavy metals in soil via adsorption, ion exchange, complexation, precipitation, and enzymatic transformation mechanisms. In this review, potential biosorbents and their metal removal capacity in soil and water are discussed. The microbial adsorbents and modified composites of agricultural biomasses show improved performance, stability, reusability, and effectively immobilize heavy metals from soil and water. In the future, researchers may consider the modified composites, encapsulated biosorbents for soil and water remediation.
