Jan 01, 2018 1. Introduction. Thallium is a nonessential toxic element that causes an environmental hazard (Rodríguez-Mercado and Altamirano-Lozano, 2013).Tl is present in two speciation forms, Tl(I) and Tl(III), which strongly differ in terms of environmental mobility and toxicity.

Sep 11, 2003 Thallium was determined in 120 samples of soil and 30 samples of stream sediments from the southeastern part of the Silesian-Cracowian zinc−lead ore deposits. Soil samples were taken from topsoils (0.0−0.2 m) and bottom soils (0.8 and 1.0 m). Thallium was determined by flow-injection−differential-pulse anodic stripping voltammetry. The samples were decomposed sequentially

translocation, and storage of trace elements (DOE, 1994; Tangahuet al., 2011). In plants, monovalent thallium ions (Tl+) do not complex with other materials and are not transformed into trivalent ions (Tl3+). Therefore, almost all thallium found in plants is the uncomplexed ionic Tl+ species and is not detected as Tl3+ (Mestek et al., 2007). For

In zinc-lead ores thallium concentration ranges from below 0.2 to 550 mg/kg. Its average concentration of 52.1 mg/kg is very high in comparison to the copper ores (1.3 mg/kg). The geometric mean (9.8 mg/kg) and median (11.1 mg/kg) are also high when compared with the corresponding values in the sedimentary rocks, especially in carbonates

Oct 26, 2016 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.

In 1981 the production of thallium in the USA was discontinued. Sources for the production of thallium are zinc, lead and sometimes copper or iron smelters and sulfuric acid plants. Flue dust in particular is used as a thallium source (Zitko, 1975a; Smith & Carson, 1977; Micke et al., 1983; Briese et al., 1985).
