hair analysis iodine lithium lead uranium selenium mercury aluminum arsenic

TLDR Hair samples showed changes in chemical elements over time and location in Venezuela.

The study analyzed hair samples from 316 Venezuelan subjects between 1991 and 2011 to assess the presence of essential and toxic chemical elements. Hair analysis, which reflects months of exposure, showed a decrease in iodine, lithium, and lead concentrations over the years. Uranium levels were higher in the insular region, selenium was more concentrated in the Andes, and mercury was elevated in Tucupita. The study highlighted the geographical and temporal variations in nutrient elements like iodine, lithium, and selenium, and toxic elements such as lead, aluminum, uranium, and arsenic.
