The United Nations proposed Sustainable Development Goals to promote healthy, safe and resilient lives. In recent years, indoor air pollution has been attracting increasing consideration listed as one of the prime environmental hazards. Thus, it is vital investigate influence outdoor on quality. To fill this lacuna, study conducted simultaneous indoor–outdoor measurements particulate matter with a diameter ≤2.5 μm (PM 2.5 ) their metallic composition (Zn, Na, Cr, Cu, Ba, Ni, Ca, Al, Mg, Fe, K Pb) in urban residential buildings Agra. Results showed higher PM concentrations indoors (83.2±15.8 μg/m 3 compared outdoors (73.5±12.2 an indoor/outdoor ratio 1.13, indicating dominance emission sources (cooking building materials). Infiltration analysis was applied transport particles. Zn, Ba Ni were high (I/O > 1) while Pb dominant < 1). This identified four potential source factors both outdoor. Field scanning electron microscope revealed difference morphologies (mostly spheroidal particles C, S, Cl indoors). These findings will help develop strategies control metals , reducing adverse health effects.
