“…Herbaria are widely recognized as a source of information on plant species, especially of taxonomic, genetic, and phytogeographic data (Gei et al, 2020; van der Ent, Echevarria, et al, 2019; van der Ent, Ocenar, et al, 2019). In addition to traditional (taxonomical) analyses of herbarium data, specimens have been increasingly used in recent years for elemental analysis and extraction of information on the plant ionome/elementome (Invernón et al, 2021). Aiming at revealing new (hyper)accumulator species, this approach for quantitative determination of elemental concentrations in plant samples has been called “Herbarium X‐ray Fluorescence Ionomics” and allows the analysis of entire taxonomic groups or the flora of a given geographical area in a short time without damaging the herbarium material (Purwadi et al, 2022; van der Ent, Echevarria, et al, 2019; van der Ent, Ocenar, et al, 2019).…”

X‐ray fluorescence spectroscopy (XRF) is a relatively new method for non‐destructive elemental analysis of herbarium material that meets the scientific interest in being capable of discovering new hyperaccumulator plant species. Since the genus Noccaea (Brassicaceae family) is known to be one of the most numerous in term of the hyperaccumulator plant species it contains, especially those that hyperaccumulate Ni, the herbarium material available worldwide represents a great resource for expanding our knowledge of their elemental profiles. In this first systematic XRF scanning of herbarium specimens of the genus Noccaea, a total of 794 specimens from the collection of the National Museum of Natural History in Paris (MNHN) were analyzed, and the raw values obtained were corrected using regression formulas against inductively coupled plasma atomic emission spectroscopy data. Hyperaccumulation of Ni was detected in 90 specimens covering 21 taxa, with Ni concentrations reaching up to 48,700 mg kg−1 in Noccaea cappadocica, an ultramaficophyte from Syria. Zinc concentrations above the hyperaccumulation threshold were found in 210 specimens covering 23 taxa, most of which belonged to different subspecies of Noccaea caerulescens, with the highest concentration reaching up to 56,200 mg kg−1 in N. caerulescens subsp. caerulescens. Although the accumulation of Ni and Zn is contrasting in most of the specimens studied, in 10 specimens, predominantly belonging to N. caerulescens, simultaneous hyperaccumulation of Ni and Zn was found. This study also revealed previously unknown hyperaccumulation of Ni in several Noccaea taxa, as well as a simultaneous hyperaccumulation of Ni and Zn that needs to be confirmed by further experimental and field studies.

“…Both methods are time-consuming, destructive, and use harmful chemicals and flammable gas (Wilschefski and Baxter, 2019). The recent development of X-ray fluorescence spectroscopy (XRF) has allowed non-destructive and high-throughput elemental analysis for both living samples and herbarium specimens (Invernón et al, 2021;van der Ent et al, 2022). This new analytical approach facilitates and speeds up the discovery of hyperaccumulators, thus the number is expected to increase in the near future (Jaffré et al, 1976;Manara et al, 2020;Reeves et al, 1999;van der Ent and Mulligan, 2015).…”

Soil is a non-renewable natural resource that forms the foundation for the life of numerous terrestrial organisms. Importantly, it supports ecosystems and human communities by serving as a medium for agricultural production and providing habitats for several animals and plants (Cassidy et al., 2013;Gao et al., 2022;. Unfortunately, the rapid expansion of human urbanization and advancements in industry have released a substantial amount of various kinds of hazardous and harmful contaminants into soils, including inorganic toxic metals. There are nine metals and metalloids commonly found in contaminated soils, including arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), selenium (Se), and zinc (Zn) (Evanko and Dzombak, 1997;FAO and UNEP, 2021;Su, 2014). Four of these metals (Cu, Ni, Zn) are essential elements required in only small concentrations for proper plant growth, but high-level exposure can be toxic for plants. The rest are non-essential elements and highly toxic for plants even at low concentrations. In addition, these contaminated metals are non-biodegradable and persistent in nature (FAO and UNEP, 2021). Due to these properties, metal contamination has been recognized as a serious concern for soil resources and human health worldwide
