“…The mean contents in lettuce and cabbage were relatively high in this group. A previous study discovered that the Brassicaceae family (cabbage, rape, turnip, and mustard) contains high levels of Tl [27]. Cabbage showed the highest concentration of Tl (4.13 ± 6.82 µg kg −1 ) in our category, although the SD across samples was large, indicating the differential Tl content in the soils where the samples were grown.…”

Thallium (Tl) is a rare element and one of the most harmful metals. This study validated an analytical method for determining Tl in foods by inductively coupled plasma mass spectrometry (ICP-MS) based on food matrices and calories. For six representative foods, the method’s correlation coefficient (R2) was above 0.999, and the method limit of detection (MLOD) was 0.0070–0.0498 μg kg−1, with accuracy ranging from 82.06% to 119.81% and precision within 10%. We investigated 304 various foods in the South Korean market, including agricultural, fishery, livestock, and processed foods. Tl above the MLOD level was detected in 148 samples and was less than 10 μg kg−1 in 98% of the samples. Comparing the Tl concentrations among food groups revealed that fisheries and animal products had higher Tl contents than cereals and vegetables. Tl exposure via food intake did not exceed the health guidance level.

“…As a nonessential toxic heavy metal that is harmful to plants [1,2], thallium (Tl) is not only more toxic than lead (Pb) and mercury (Hg), but also easily accumulated in the human body [3,4]. The minimum lethal dose of Tl (salt) in adults ranges from 0.1 to 0.7 g, usually from 0.5 to 1 g [5].…”

Thallium (Tl) is a nonessential and toxic trace metal that is detrimental to plants, but it can be highly up-taken in green cabbage (Brassica oleracea L. var. capitata L.). It has been proven that there is a significant positive correlation between Tl and Calcium (Ca) contents in plants. However, whether Ca presents a similar role for alleviating Tl toxicity in plants remains unclear, and little is known in terms of evidence for both Ca-enhanced uptake of Tl from soils to green cabbage and associated geochemical processes. In this study, we investigated the influence of Ca in soils on Tl uptake in green cabbage and the associated geochemical process. The pot experiments were conducted in 12 mg/kg Tl(I) and 8 mg/kg Tl(III) treatments with various Ca dosages. The results showed that Ca in soils could significantly enhance Tl uptake in green cabbage, increasing 210% in content over the control group. The soluble concentrations of Tl were largely increased by 210% and 150%, respectively, in 3.0 g/kg Ca treatment, compared with the corresponding treatment without Ca addition. This was attributed to the geochemical process in which the enhanced soluble Ca probably replaces Tl held on the soil particles, releasing more soluble Tl into the soil solution. More interestingly, the bioconcentration factor of the leaves and whole plant for the 2.0, 2.5, 3.0 g/kg Ca dosage group were greatly higher than for the non-Ca treatment, which could reach 207%, implying the addition of Ca can improve the ability of green cabbage to transfer Tl from the stems to the leaves. Furthermore, the pH values dropped with the increasing Ca concentration treatment, and the lower pH in soils also increased Tl mobilization, which resulted in Tl accumulation in green cabbage. Therefore, this work not only informs the improvement of agricultural safety management practices for the farming of crops in Tl-polluted and high-Ca-content areas, but also provides technical support for the exploitation of Ca-assisted phytoextraction technology.

“…Predloženi prag za klasifikaciju hiperakumulacije Tl iznosi 100 μg g-1 [38]. Iako postoji značajna koncentracija ovog metala u hiperakumlatorima, lokacije gde bi se oni mogli primeniti u fitorudarenju su vrlo ograničene [39]. Stoga je još značajniji nalaz vrsta Viola allchariensis, V. arsenica i V. tricolor subsp macedonica sa teritorije rudnika talijuma Alšar (Severna Makedonija), koje hiperakumuliraju talijum [40].…”

Phytomining is a currently developing biotechnology aiming to extract rare and precious metals from naturally enriched or polluted soils with the help of hyperaccumulator plants. On the territory of the Balkans, hyperaccumulating species mainly accumulate elements such as nickel, zinc, thallium, copper and arsenic. This paper provides an overview of the studied technologies around the world for the extraction of these elements from hyperaccumulator's biomass, as well as the areas of potential application of the obtained products. Phytomining has a potential for development in Serbia, and for this purpose it is necessary to utilitized available hyperaccumulators, as well as to investigate technologies for the extraction of metals from their biomass.
