Abstract The current study investigated indoor and outdoor levels of PM10 (particulate matter with aerodynamic diameter <10 μm), PM2.5 (particulate matter with aerodynamic diameter <2.5 μm), carbon monoxide (CO), carbon dioxide (CO2), temperature and relative humidity (RH) in 60 households located in two urban residential areas in Alexandria. In addition, indoor concentrations of PM2.5, CO and CO2 were measured simultaneously in the domestic kitchens of all monitored homes. Information on buildings characteristics (ventilation, building age, etc.), domestic activities of the occupants (smoking, cooking, and cleaning), and socioeconomic factors (monthly income and education level) were collected through a self-administered questionnaire. Furthermore, air exchange rates (AERs) were measured in the living rooms of all selected residences. Almost all measured parameters showed significant spatial variation (p < 0.01) between the two study areas. This spatial variability was mainly due to the impact of ventilation, indoor activities and socioeconomic status (SES). Households having natural ventilation through frequent opening of doors and windows had higher AERs and therefore showed stronger associations between indoor and corresponding outdoor levels of measured air pollutants compared to mechanically ventilated ones. The current study showed for the first time in Egypt the relationship between indoor air quality (IAQ) and socioeconomic factors and highlighted the importance of considering SES alongside other influencing factors when studying residential IAQ. SES variables examined in this study proved to be significant predictors for IAQ where households with lower monthly income and education level were more likely to have higher indoor pollutants’ levels. The findings of this research could identify the drivers of poor IAQ in lower socioeconomic residences.
Highlights Residential indoor air quality is affected by various indoor and outdoor factors. Actions to improve ambient air quality could result in better indoor air quality (IAQ). Socioeconomic status should be considered with other key factors of residential IAQ. Higher income and level of education decreased indoor air pollutant concentrations. This study identified the salient drivers of poor IAQ in lower socioeconomic homes.
