“…There are major components of most of the primary mineral such as quartz, feldspar and plagio-clase and minor secondary iron oxide minerals such as hematite and goethite in samples SLP01, SLP02 and SLP08. In samples SLP03, SLP04 and SLP07 the presence of mica and secondary minerals (neoformed or not) such as gypsum and jarosite as minor components is noteworthy (Cruz-Hernández et al 2018).…”

“…The considerably high BA Mn contents is surprising, considering Mn(III/IV) oxides cannot dissolve, except through a reductive dissolution mechanism. This suggests that HCl may be acting as a mild reducing agent (Table SIII), because using HNO 3 instead yields much lower extracted Mn (Cruz-Hernández et al 2018).…”

“…However, at higher contents they become toxic and cause adverse effects (Li et al 2014. Other elements such as thallium, arsenic, cadmium, mercury and lead are toxic even at low contents (Mingot et al 2011, Smith et al 2011, Yang et al 2015, Mendoza et al 2017, Cui et al 2018, Cruz-Hernández et al 2018, Pelfrêne and Douay 2018.…”

“…However, other less available chemical forms may also pose high threats to organisms because of the chemical reactions that occur upon their entry into or their interactions with the organisms (Santana-Silva 2016). The different chemical forms of PTEs depend on many factors and geochemical conditions, such as pH, their mineralogical occurrence or associations, the environmental redox status, and the availability of complexing agents (Cruz-Hernández et al 2018).…”

The potential to determine the gastric bioaccessibility (BA) of Tl, As, Pb(II), Cu(II), Zn(II) and Cd(II) using a simple extraction method was evaluated in selected samples from soils contaminated by mining and metallurgical wastes. The SBRC (Solubility and Bioavailability Research Consortium) test was used as a gastric BA comparative method versus a simple extraction method using HCl solution at pH 1.5. High correlations (r ≥ 0.98, p ˂ 0.01) were obtained between the two extraction methods for Cd(II), Cu(II), Tl and Zn(II), in all samples investigated. Bioaccessible As, however, only showed a high correlation in the metallurgical area (r = 0.99, p ˂ 0.01), but not in the mining area (r = 0.88, p ˂ 0.01). Conversely, Pb(II) showed a better correlation in samples from the mining area (r = 0.99, p ˂ 0.01) than in those of the metallurgical area (r = 0.92, p ˂ 0.01). Three experimental conditions of the extraction procedures ensured the high correlations observed: (1) Maintaining a strict pH control of 1.5 (± 0.1), (2) a stirring time of 1 h (± 1 min), and (3) filtration of the extraction mixture through a membrane of small pore size (0.05 µm). Bioaccessible Tl was detected in all samples, a fact that has not been reported before in these environments, and alerts to potential health risks not previously identified.

“…Specifically, a concentration of 2.9 mg/kg was detected in an old mining area located in Linares district (south Spain) (Cortada et al 2018); while, a concentration range of 0.67-2.43 mg/kg was observed from aluminosilicates located in two areas near Madrid city. This remains on the site affecting the soils and sediments of the natural watercourses near the city (Cruz-Hernandez et al 2018).…”

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.
