“…Moscow grain's total Cd concentration was also greater than the grain from the southern Idaho locations such as Parma (0.042 mg kg −1 ) and Kimberly (0.043 mg kg −1 ). A study conducted in Zhejiang Province in China found that Cd concentrations in wheat were between 0.048 and 0.053 mg kg −1 (Lu, 2020). In Austria, the Cd concentrations varied from 0.01 to 0.10 mg kg −1 (Wenzel et al., 1996).…”

Current efforts to reduce the maximum allowable cadmium (Cd) concentrations in wheat (Triticum aestivum L.) for at-risk populations such as infants require sourcing wheat with low concentrations of Cd. Since Idaho (USA) is a major wheat supplier, there is a need to understand which varieties and locations in Idaho produce wheat containing low Cd. Therefore, the main objective of this paper is to report on a survey of total Cd concentrations in 469 wheat grain samples and 216 soil samples from several varieties and locations throughout Idaho. Total Cd concentrations in wheat grain ranged from <0.01 to 0.28 mg kg −1 , varying by both wheat variety and location grown. Total soil Cd ranged from 0.450 to 1.85 mg kg −1 . Bioaccumulation factor (BAF) was calculated by dividing the grain total Cd concentration by the soil total Cd concentration and ranged from 0.05 to 0.5. The variety 'UI Sparrow' had the lowest mean BAF (0.06), and several other varieties were also relatively low. Overall, almost all wheat varieties meet European Food Safety Authority (EFSA) requirements for Cd concentration for adult consumption. However, meeting the EFSA maximum allowable limit of Cd in infant food requires planting varieties noted for low Cd uptake, like UI Sparrow, and careful selection of growing regions with the lowest total soil Cd, such as northern, central, or western Idaho.

“…Through application of EFA technology, the efficiency of soil remediation was improved [5,6], the growth and trace metal content of aquatic plants are affected [2], and the harmful contaminants, which strictly limited the land application of the sludge, were reduced from sludge [7]. The EFA technology was also being used in drug delivery research [8].…”

Electric field assisted technology has been widely used in many fields. Candida tropicalis degrading thiophene has been successfully screened by electric field assisted screening (EFAS). However, the mechanism of EFAS is yet unclear. In this study, the cell concentration of C. tropicalis at different locations in the electric field was studied. In the electric field, C. tropicalis cells migrate towards the cathode plate. When the loading electric field intensity was 0.6 V /cm, the concentration of cells near the cathode plate reached the maximum and it was nearly stable at 15 minutes of loading time. Analysis of the cell morphology at different locations showed that only the budding cells could migrate in the electric field. The charged characteristic of the budding cells in the electric field explained the screening mechanism of thiophene-degrading C. tropicalis by EFAS. The results can provide a theoretical foundation for EFAS in screening other biodegradable microorganisms.
