“…Oxidizable/ organically bound fractions were highest in the SC soil that was higher soil organic matter content. Similar results of residual fractions making up the major part of thallium fractions in soils formed on floodplain terraces (Jakubowska et al 2007), in accidently polluted soils (Rao et al 2008), in river basin sediment (Liu et al 2010), and in sediment formed by a tsunami (Lukaszewski et al 2012), which ranged between 41.0 % and 96.9 %, have been reported. In addition, major labile forms of thallium in different materials were mostly reducible and/or oxidizable fractions.…”

The objectives of this study were to investigate the distribution of thallium in soils collected near suspected areas such as cement plants, active and closed mines, and smelters and to examine the extraction of thallium in the soils using 19 single chemical and sequential chemical extraction procedures. Thallium concentrations in 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). Thallium extractability with 19 single chemical extractants from selected soils near cement plants ranged from 0.10% to 8.20% of the total thallium concentration. In particular, 1.0 M NH4Cl, 1.0 M (NH4)2SO4, and 1.0 M CH3COONH4 extracted more thallium than other extractants. Sequential fractionation results of thallium from different soils such as industrially and artificially contaminated soils varied with the soil properties, especially soil pH and the duration of thallium contamination.

“…Heim et al (2002) investigated thallium contents in soil and plants in the EuroRegion Neisse (includes Germany, the Czech Republic, and Poland) and found 0.5 mg/kg Tl in the median topsoil. Tl concentrations in the median French topsoils were 0.3 mg/kg (Tremel et al 1997), and soils from southeastern part of Silesian-Cracovian zinc-lead ore deposit region contained 0.44 μg/g as median level of Tl (Jakubowska et al 2007). A study of Asami et al (1996) showed an average of 0.33 mg/kg in Japanese unpolluted surface soils.…”

Surface soil samples collected from a Pb and Zn mining area in India were subjected to multi-elemental analysis by using inductively coupled plasma-atomic emission spectrometry. Multivariate statistical methods such as principal component analysis and cluster analysis, coupled with correlation coefficient analysis, were used to analyze the data and to apportion the possible sources of elements in soils of a metal mining area. Soils in this area have elevated heavy metal concentrations especially Pb, Zn, Mn, Cu, As, and Tl. Using principal component (PC) analysis, six components were extracted, out of which two PCs explaining 50.12% of total variance are more important. The first principal component with a high contribution of Ag, As, Be, Cd, Co, Cu, Mg, Mn, Ni, Pb, and Zn was deemed to be technogenic/anthropogenic component, and the second principal component, with high loadings for the five discerning variables (Al, Be, Cr, K, Li), was considered as lithogenic component. The third component having strong loadings of Ba, Ca, K, and Na is supposed to have a mixed origin (lithogenic as well as technogenic). Electrical conductivity and total organic matter were not correlated with any element and also have a strong loading in the fifth component which is probably the biomass and ions present in these soils. The findings of the principal component analysis were also substantiated by the cluster analysis. The present study would not only enhance our knowledge regarding the soil pollution status in the study area but would also provide us information to manage the sources of these elements in the study area.

“…A sequential extraction scheme used to investigate Tl fractionation in polluted soils from Poland indicated that almost half of the Tl was in a nonlabile fraction and associated with the soil parent material [80]. Of the labile fraction, about 30 % was extracted with a reducing agent and presumably associated with Mn-and Feoxides, and about 10 % was extracted with an oxidizing agent and presumably associated with soil organic matter.…”
