“…Naturally, Tl can be observed in oxidation states of Tl + and Tl 3+ (Scheckel et al 2004). In most evidenced cases, Tl can be found as mostly stable in mining waste/soils (Grösslová et al 2018) or can be released into the atmosphere in the form of non-evaporative compounds with various oxide, hydroxide, and sulfide composites. The similarity of the metallic and covalent radii of Tl to that of lead (Pb) implies their similar behavioral patterns in the aquatic system (USEPA 1979).…”

Thallium (Tl) is an extremely harmful metal that is substantially distributed in the environment. It can threaten human health via consumption of food potentially derived from Tl-contaminated agricultural production. Little information is available on how to utilize biochar to remediate Tl contamination in agricultural soils. More efforts are urgently needed to be devoted to developing effective techniques to empower biochar with high selectivity of Tl in agricultural soils. In this review, we provided comprehensive information on Tl contamination in agricultural soils. We also discussed recent developments and assessed the current status of biochar applications. We briefly reviewed the bridge between biochar preparation technology and utilization wherein further developments can exhibit potential in terms of Tl remediation. Hence, biochar is expected to exhibit excellent Tl remediation performance in contaminated agricultural soils with promising application prospects. The obtained knowledge provides further insights into the remediation of Tl contamination in agricultural soils.

“…Thallium (Tl) is of great concern due to its geoavailability, mobility, dispersivity, bioaccessibility, bioavailability, and toxicity to plant and animal species. Many thallium studies have been centered on natural and man-induced pollution sources in the context of their implications for the environment and humans (Zhang et al 1998;DelValls et al 1999;Cheam 2001;Xiao et al 2012Xiao et al , 2004aMurciego et al 2010;Casiot et al 2011;Bačeva et al 2014;Tatsi and Turner 2014;Gomez-Gonzalez et al 2015;Vaněk et al 2015Vaněk et al , 2016Campanella et al 2016Campanella et al , 2017Wojtkowiak et al 2016;Biagioni et al 2017;Grösslova et al 2018;Perotti et al 2018;Cruz-Hernández et al 2018;D'Orazio et al 2020). It should be mentioned that different physicochemical, environmental, toxicological and technological issues of this toxic metal have been reviewed in several papers (e.g., Kazantzis 2000;Heim et al 2002;Twidwell and Williams-Beam 2002;Peter and Viraraghavan 2005;Karbowska 2016;Caritat and Reimann 2017;Belzile and Chen 2017;Xu et al 2019;Liu et al 2019a;Zhang and Rickaby 2020).…”

This overview presents the updated physicochemical characteristics of thallium and its stable isotopes (205Tl/203Tl) in the context of their occurrence and fate in abiotic and biotic systems. This also deals with the thallium behavior in geochemical interactions in and between different environmental compartments and describes its natural (geogenic) and industrial sources. The particular emphasis is placed on some extreme environments, including acid mine drainage areas where oxidation processes of Tl-bearing pyrite and other sulfides lead to very high concentrations of this metal in reactive acidic waters. Many geochemical studies have also employed stable thallium isotopes to reconstruct redox conditions in different environmental systems, to fingerprint relative pollution source strengths and to evaluate mobility of this element and its geochemical interactions in the mineral-water and soil–plant systems. This is the reason why this overview also highlights the growing potential of stable Tl isotopes in solving different geologic and environmental issues. Graphic abstract

“…Thallium is a heavy metal whose toxicity to mammals is second only to that of methylmercury and far exceeds that of chromium, mercury, and lead (Campanella et al, 2016; Campanella et al, 2017; Casiot et al, 2011; Galván-Arzate & Santamaría, 1998; Grösslová et al, 2018; Li, Xiao & Zheng, 2012; Liu et al, 2016a; Perotti et al, 2017). Thallium can be accumulated in bone marrow, kidneys and different organs, thereby affecting the gastrointestinal and urinary tract, and even causing permanent damage in muscle atrophy or central nervous system (Galván-Arzate & Santamaría, 1998; Peter & Viraraghavan, 2005).…”

Rutile nano-titanium dioxide (RNTD) characterized by loose particles with diameter in 20–50 nm has a very large surface area for adsorption of Tl, a typical trace metal that has severe toxicity. The increasing application of RNTD and widespread discharge of Tl-bearing effluents from various industrial activities would increase the risk of their co-exposure in aquatic environments. The adsorption behavior of Tl(I) (a prevalent form of Tl in nature) on RNTD was studied as a function of solution pH, temperature, and ion strength. Adsorption isotherms, kinetics, and thermodynamics for Tl(I) were also investigated. The adsorption of Tl(I) on RNTD started at very low pH values and increased abruptly, then maintained at high level with increasing pH >9. Uptake of Tl(I) was very fast on RNTD in the first 15 min then slowed down. The adsorption of Tl(I) on RNTD was an exothermic process; and the adsorption isotherm of Tl(I) followed the Langmuir model, with the maximum adsorption amount of 51.2 mg/g at room temperature. The kinetics of Tl adsorption can be described by a pseudo-second-order equation. FT-IR spectroscopy revealed that -OH and -TiOO-H play an important role in the adsorption. All these results indicate that RNTD has a fast adsorption rate and excellent adsorption amount for Tl(I), which can thus alter the transport, bioavailability and fate of Tl(I) in aqueous environment.
