Workers in this field often lack protective safety gear and are exposed to mining pollutants that can adversely affect their health and well-being. Given the limited availability of occupational biomonitoring studies in the mining industries of countries like Sudan, this study aimed to investigate the effectiveness of a micro Particle Induced X-ray Emission (µ-PIXE) approach to biomonitor human tissue—specifically hair samples—obtained from artisanal gold miners for the presence of toxic metals, including iron (Fe). Gold miners from the region in Sudan voluntarily provided hair samples, which were subsequently analyzed using the PIXE technique. The analysis revealed a range of elements, including sulfur (S), chlorine (Cl), potassium (K), calcium (Ca), titanium (Ti), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), bromine (Br), strontium (Sr), and lead (Pb). However, some essential elements, such as silicon (Si) and chromium (Cr), were notably absent. All samples contained elevated levels of sulfur, phosphorus (P), and chlorine, with some samples indicating the presence of lead (Pb). <br />Additionally, only six out of the nineteen samples contained lead, and its absence can result in metabolic issues and hinder tissue growth. Furthermore, all analyzed hair samples exhibited low levels of essential elements like zinc, which is vital for plant disease resistance, photosynthesis, cell membrane integrity, protein synthesis, and pollen formation. https://jpoll.ut.ac.ir/article_99867_4a97a817e8c11b30762c1f1f67a2c9b4.pdf
