“…Abstract This research investigates the concentrations, sources, and health risks of polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs (NPAHs) in particulate matter with an aerodynamic diameter of 10 $$\mu$$ m or less (PM $$_{10}$$ ) from critical urban centers in northern Mexico: Metropolitan Monterrey Area (MMA), Chihuahua (CHI), and
Ciudad Juárez (CDJ). Advanced gas chromatography-mass spectrometry (GC-MS and GC-NCI-MS) revealed significant PAHs concentrations, with levels in MMA reaching 108.89 ± 99.90 ng/m $$^3$$ , CHI at 100.69 ± 122.60 ng/m $$^3$$ and CDJ at 73.26 ± 90.85 ng/m $$^3$$ . …”
