摘要: The present work was conducted to highlight the elemental composition, quantify extent of pollution, and assess linked risk due exposure metals in dust samples. collected samples from Al-Qassim Region were subjected two complementary analytical techniques: instrumental neutron activation analysis inductively coupled plasma mass spectrometry. A total 42 elements determined, concentrations (mg/kg) compared with corresponding values literature. Considerable Br (7.1), Zr (640), Hf (16.5), As (8.9), Sb (0.7) observed. Enrichment factor (EF) calculated be more than 7 for same elements, this a good indicator mixed source pollution these elements. integrative index (PI) sorted Bureydah South as strongest contributor contamination. assessment showed no hazard observed inhalation selected that distinguished their high toxicity.
