摘要: PM2.5 (particulate matter with an aerodynamic diameter <2.5 μm) samples were collected in the indoor environments of 15 urban homes and their adjacent outdoor Alexandria, Egypt, during spring time. Indoor carbon dioxide (CO₂) levels also measured concurrently. The results showed that concentrations sites, daily averages 45.5 ± 11.1 47.3 12.9 µg/m³, respectively, significantly higher than ambient 24-hr standard 35 µg/m³ recommended by U.S. Environmental Protection Agency (EPA). CO₂levels correlated corresponding levels, demonstrating convection infiltration could lead to direct transportation indoors. Ventilation rates selected residences ranged from 1.6 4.5 hr⁻¹ median value 3.3 hr⁻¹. indoor/outdoor (I/O) ratios monitored varied 0.73 1.65 average 0.99 0.26 for PM2.5, whereas those CO₂ranged 1.13 1.66 1.41 0.15. sources personal activities, including smoking cooking, found influence levels.
