Thallium is a non essential and highly toxic metal listed by USEPA and the European Water Framework Directive as a priority pollutant. It is present in the environment mainly as Tl(I) and Tl(III) usually at very low concentrations, which makes it a challenging element requiring high sensitive instrumental techniques to measure it in complex matrices.

Thallium concentrations range between 7 and 244 ng/g for a basalt-based lateritic profile and 37–652 ng/g within a greywacke lateritic profile. The average Tl stable isotope composition of the two profiles is similar to many typical igneous materials, however, the intense tropical weathering causes a small but resolvable fractionation of Tl ...

Thallium concentration was measured with an atomic absorption spectrometer. Thallium concentrations averaged 20.84 mg kg-1 and varied from 4.42 to 49.82 mg kg-1. In all studied soils they exceeded values typical for uncontaminated soils (0.02 to 2.8 mg Tl kg-1). This indicates that Tl contamination may threaten the environment and public health.
