“…Определение содержания РЗЭ в растениях становится инструментом, позволяющим решать разнообразные задачи, такие как изучение качества воздуха в сельских, городских и промышленных экосистемах [10][11][12], исследование возможности очищения водоемов от РЗЭ за счет биоаккумуляции различными водными растениями [12,13], изучение уровня содержания РЗЭ в биообъектах для оценки экологической ситуации в регионе [14], детальное изучение токсичности РЗЭ для растительных организмов [6,7]. Также эта группа элементов показала себя как возможный маркер при определении происхождения и способа выращивания растений, употребляемых в пищу [15].…”

Method of microwave digestion using HNO3, HCl and HF in MARS‑5 system followed by ICP-MS analysis is proposed for determination of rare earth elements (REE) in plant materials. Limits of detection are 0.0001–0.001 ppm and allow for determination of all REE in certified reference materials Tr‑1, LB‑1 and EK‑1 and new reference material NSP‑1, relative standard deviations are lower than 13 %.Influence of HF addition during microwave digestion in UltraWAVE system on the ICP-MS analysis of REE in plant materials depending on silica content is studied. Necessity of HF addition during microwave digestion for better REE recoveries is shown for plant materials with Si contents exceeding 0.1 %

“…Unlike heavy metals, the phytotoxicity of REEs has not yet been su ciently studied (Thomas et al 2013). It is known that the concentration of light REEs in the roots of vascular plants is usually higher than in other plant organs, including shoots (Carpenter et al 2015;Grosjean 2019;Mikołajczak et al 2017;Nazreen et al 2017;Thomas et al 2013). However, the accumulation of these in leaves and stems, being the main organs of photosynthesis, can have major consequences for plant growing (Thomas et al 2013).At the same time, effective REE transport from the root system to the leaves is one of the most important criteria in an effective phytoextraction strategy: with the active accumulation of REEs in the aboveground parts of plants, these are easily removed from the environment (Mikołajczak et al 2017).Research on abandoned wastelands has shown that Poaceae are the dominant plant family there (Mishra et al 2017;Singh 2011).…”

This paper presents the results of an assessment of the ground and plant chemistry in disturbed areas exposed to impacts from adjacent rare metal ore concentration waste storage facilities.The focus of research were areas with sparse vegetation cover near the site of the first tailing storage facility (TSF), which is not exploited from 1985. In the summer of 2019, on three key plots within the study area, plant samples were collected at a small distance from the TSF and operating process transport routes (<1 km). Based on a bulk chemistry analysis of the ground samples, concentration values were measured above the background values adopted for the region’s soil parent rock materials, and in the absence thereof, the clarkes of elements in acidic (SiO2 >60%) rocks found in the earth's crust. Grounds were found to be rich in Ta, Ce, La, Th, Zr, Nb, which are also present in the loparite ores of various origins mined by the operation.The chemistry was examined of Salix spp. commonly found both in the study area and in the region as a whole and of wavy hair grass Avenella flexuosa L. An abnormally high level of zinc accumulation was observed in Salix lapponum (>850 mg/kg, biological absorption coefficient (BAC) >4), and technological transport influence was proposed as a possible cause. High paired correlation coefficients of rare and trace elements with Al and with each other (>0.9) in the bulk chemistry analysis of Salix spp. indicate the likelihood of deposition of minerogenetic dust particles. Based on the observed values of the BAC, the plants were classified into biological accumulation (BAC >1) and biological uptake (BAC <1) classes and the latter was found to be dominant.
