“…Taking advantage of this peculiarity, some researchers have developed soil remediation technologies by plants (Ashwini Waoo 2011). Tang et al showed that Cd had a higher translocation factors from soil to root in rice (Tang et al, 2019 ). Bonari et al also mentioned that most of the trace elements analysis in the medicinal herb showed significant differences ( Hypericum perforatum L. ) (Bonari et al, 2018 ).…”

“…Hakanson's evaluation model was applied in the present paper to evaluate the pollution level of the soil at the medicinal planting area (Hakanson, 1980 ). There are various models to evaluate the ecological risk of heavy metals in soils, such as Nemerow’s Pollution Index (NPI), Geoaccumulation Index (Igeo), Pollution Load Index (PLI) (Mohammadi et al, 2020 ; Tang et al, 2019 ). 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 ).…”

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.

The index of geo-accumulation (I geo) and the pollution load index (PLI) were used to assess the pollution level and the U.S. Environmental Protection Agency (EPA) health risk model was implemented to determine the health risk for children. Besides, a geographic information system (GIS) was utilized to map the distribution characteristics of risk elements contents. The results showed that: (1) the mean content of Mn was the highest in each park. Besides, the mean content of all risk elements except As exceeded the background value of Shaanxi in each park. (2) The I geo of Co was obviously higher than other elements in each park and the highest (4.07) content occurred in the Xing Qing Park (XQP). The pollution condition of the Urban Sports Park (USP) was the most serious among the four parks. (3) The children were more susceptible to risk elements pollution through oral intake. (4) The hazard indices (HI) of non-carcinogenic risk (NCR) were within the safe range (HI = 1) and the carcinogenic risks (CR) of Cr, Ni, As and Co for children were within the receivable range in each park.

“…Excessive accumulation of heavy metals in the paddy field from anthropogenic activities like using contaminated irrigated water caused by mining activities had been the foundation of understanding how heavy metal can be transferred and accumulate in the human body by consuming contaminated food crops. High accumulation of heavy metals in cereals can be detrimental to human health (Tang et al, 2019). Cadmium was the first heavy metal that had been associated with heavy metal toxicity risk in the consumption of contaminated rice with diseased called Itai itai disease and causing cancer.…”

The prospect of three native upland paddy landraces known as Bokilong, Ponsulak and Taragang as heavy metals accumulator for phytoremediation was determined. Bioaccumulation of heavy metals (As, Cd, Cr, Cu, Fe, Pb, and Zn) in various parts of paddy plants collected from Kiulu valley, North Borneo in the natural conditions during the vegetative phase and harvest season were analysed by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). All selected heavy metals were traced in soil samples of all three paddy landraces rhizosphere where the most available heavy metals were Fe followed by Zn. Heavy metals bioavailability in soil seemed to be influenced by the local climate of the cultivation field. Bokilong landrace is an accumulator of As, Cd, Cu, Pb and Zn. Ponsulak paddy can help clean up the soil by phytoextraction of As, Cr, Cu, Fe and Zn. Taragang paddy has a prospect in phytoextraction of Cd and Pb to remediate excess amount of this element in the soil. Different heavy metals concentration trends were accumulated in these three paddy landraces in grain indicated different nutritional values. Heavy metal uptake characteristic differs between upland paddy landraces and there was also environmental influence affecting the mobility rate of these elements in paddy plant depending on the element type and paddy genotype.
