“…Thallium concentrations in Korean soils near cement plants were distributed between 1.20 and 12.91 mg kg −1 . However, soils near mines and smelters contained relatively low thallium concentrations ranging from 0.18 to 1.09 mg kg −1 (Jin-Ho Lee et al 2015). Ores in western Małopolska contain up to 90 mg kg −1 (Zn sphalerite ores) and up to 1000 mg kg −1 of thallium (Fe marcasite ores) (Cabała 2009).…”

Thallium is released into the biosphere from both natural and anthropogenic sources. It is generally present in the environment at low levels; however, human activity has greatly increased its content. Atmospheric emission and deposition from industrial sources have resulted in increased concentrations of thallium in the vicinity of mineral smelters and coal-burning facilities. Increased levels of thallium are found in vegetables, fruit and farm animals. Thallium is toxic even at very low concentrations and tends to accumulate in the environment once it enters the food chain. Thallium and thallium-based compounds exhibit higher water solubility compared to other heavy metals. They are therefore also more mobile (e.g. in soil), generally more bioavailable and tend to bioaccumulate in living organisms. The main aim of this review was to summarize the recent data regarding the actual level of thallium content in environmental niches and to elucidate the most significant sources of thallium in the environment. The review also includes an overview of analytical methods, which are commonly applied for determination of thallium in fly ash originating from industrial combustion of coal, in surface and underground waters, in soils and sediments (including soil derived from different parent materials), in plant and animal tissues as well as in human organisms.

“…24,25 Thus, the content of thallium in environmental systems has to be strongly regulated and controlled. A previous study 18 reviewed worldwide standards for thallium contamination levels in soil (Canada and Switzerland, 1 mg/kg); occupational exposure limits in air (Argentina, Mexico, United States, Canada, U.K., and Germany, 0.1 mg/m 3 , and Russia, 0.01 mg/m 3 ); and maximum contaminant levels in drinking water (United States, 2 mg/m 3 ).…”

Thallium Transfer from Hydrochloric Acid Media into Pure Ionic Liquids

et al. 2016

Pure hydrophobic ionic liquids are known to extract metallic species from aqueous solutions. In this work we have systematically investigated thallium (Tl) extraction from aqueous hydrochloric acid (HCl) solutions into six pure fluorinated ionic liquids, namely imidazolium- and pyrrolidinium-based ionic liquids with bis(trifluoromethanesulfonyl)imide and bis(fluorosulfonyl)-imide anions. The dependence of the Tl extraction efficiency on the structure and composition of the ionic liquid ions, metal oxidation state, and initial metal and aqueous acid concentrations have been studied. Tl concentrations were on the order of picomolar (analyzed using radioactive tracers) and millimolar (analyzed using inductively coupled plasma mass spectrometry). The extraction of the cationic thallium species Tl(+) is higher for ionic liquids with more hydrophilic cations, while for the TlX(z)(3-z) anionic species (where X = Cl(-) and/or Br(-)), the extraction efficiency is greater for ionic liquids with more hydrophobic cations. The highest distribution value of Tl(III) was approximately 2000. An improved mathematical model based on ion exchange and ion pair formation mechanisms has been developed to describe the coextraction of two different anionic species, and the relative contributions of each mechanism have been determined.

“…Lee. et al conducted a study on soil in South Korean locations and reported the estimated Tl content of 1.20-12.91 mg kg −1 in the soil near a cement industry facility, and 0.18-1.09 mg kg −1 near a smelter and mine [44]. In addition, 2.28 ± 1.39 mg kg −1 of Tl was found in rhizospheric soils near cement plants in China [45].…”

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.
