“…The inflow of Cd 2+ at 300 µm around the root tips of Bidens pilosa L. plants was reduced when treated with 16 mM Ca 2+ , 8 mM Mg 2+ , 8 mM SO 4 2- , or 18 mM K + as detected by NMT, indicating that treatment at a large concentration of nutrient ions inhibited the absorption of Cd 2+ ( Wang et al., 2023 ). Using the NMT method, a peak in the net Cd 2+ flux was observed at a distance of 100 µm from the surface of the root tips of Amaranthus hypochondriacus L., a plant famous for its ability to accumulate large quantities of this metal ion ( Han et al., 2023 ). Furthermore, fluorescent labeling revealed that Ca 2+ channel blockers conspicuously suppressed Cd 2+ influx compared to other blockers, suggesting that Ca 2+ channels serve as primary pathways for Cd entry through the roots ( Han et al., 2023 ).…”

In a similar observation, Cd primarily entered Sedum plumbizincicola through Ca 2+ channels; the net flux of Cd 2+ altered from inflow to outflow as the concentration of Ca 2+ increased ( Li et al., 2017b ).…”

Heavy metal (HM)-induced stress can lead to the enrichment of HMs in plants thereby threatening people’s lives and health via the food chain. For this reason, there is an urgent need for some reliable and practical techniques to detect and analyze the absorption, distribution, accumulation, chemical form, and transport of HMs in plants for reducing or regulating HM content. Not only does it help to explore the mechanism of plant HM response, but it also holds significant importance for cultivating plants with low levels of HMs. Even though this field has garnered significant attention recently, only minority researchers have systematically summarized the different methods of analysis. This paper outlines the detection and analysis techniques applied in recent years for determining HM concentration in plants, such as inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS), atomic fluorescence spectrometry (AFS), X-ray absorption spectroscopy (XAS), X-ray fluorescence spectrometry (XRF), laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS), non-invasive micro-test technology (NMT) and omics and molecular biology approaches. They can detect the chemical forms, spatial distribution, uptake and transport of HMs in plants. For this paper, the principles behind these techniques are clarified, their advantages and disadvantages are highlighted, their applications are explored, and guidance for selecting the appropriate methods to study HMs in plants is provided for later research. It is also expected to promote the innovation and development of HM-detection technologies and offer ideas for future research concerning HM accumulation in plants.

“…Cd is also capable of being bound to phosphorites and sulfides, resulting in increased accumulation in soils, due to the use of these rocks in the fertilizer industry [8]. Moreover, apart from fertilizers, its usage in industry, mining, and pesticides can elevate the Cd content in both soil and water [9]. Cadmium is a highly labile element in soil and can easily be assimilated by plants.…”

Cadmium (Cd) contamination poses a major threat to plants and human health, as well as to ecosystem services. Biostimulants provide a promising eco-friendly solution to enhance the phytoremediation of Cd-contaminated soils. We examined the influence of a humic and fulvic acids-based biostimulant on two plant species, e.g., Plantago weldenii and Sonchus oleraceus (common sowthistle), in a soil spiked with Cd at 45 mg kg−1. The aim of this study was to determine whether a biostimulant can potentially affect Cd mobility in soil and absorption in plant tissues. We found that the biostimulant significantly decreased Cd bioavailability (recorded as DTPA extractability) in the soil where Plantago was grown from 17.57 to 13.12 mg kg−1, probably due to the Cd immobilization effect of the added biostimulant. However, the biostimulant had the opposite effect in the soil where S. oleraceus was grown (Cd-DTPA significantly increased from 10.13 to 13.03 mg kg−1). S. oleraceus was found to have accumulated higher Cd concentrations in its aerial parts, resulting in a soil-to-plant transfer value close to 1 and root-to-shoot translocation value well above 1. These two indices exhibited the potential of S. oleraceus to be used as hyperaccumulator in Cd-contaminated soils, while P. weldenii behaved rather as a Cd excluder. These findings highlight the complex dynamics of added biostimulants and Cd behavior in soil and plants. We recognize the need for further research so that the mechanisms dictating Cd behavior after biostimulant application can be better elucidated.
