Article Synopsis
- Thorium is a common radionuclide found in the earth's crust that contributes to radiation exposure in living organisms, with concentrations altered by human activities like mining.
- In Zacatecas State, Mexico, historical mining has resulted in waste dumps that could affect soil composition, but previous studies on thorium levels in this area have been limited.
- Analysis of 33 soil samples revealed an average thorium concentration of 13.6 mg/kg, consistent with natural levels, suggesting no significant anthropogenic alteration, although slight isotopic disequilibrium was noted due to the region's climatic conditions.
This paper presents an evaluation of uncertainty associated to analytical measurement of 18 polycyclic aromatic compounds (PACs) in ambient air by liquid chromatography with fluorescence detection (HPLC/FD). The study was focused on analyses of PM(10), PM(2.5) and gas phase fractions.
