background: in the past few decades, indoor air pollution (iap) has become a primary concern to the point. it is increasingly believed to be of equal or greater importance to human health compared to ambient air. however, due to the lack of comprehensive indices for the integrated assessment of indoor air quality (iaq), we aimed to develop a novel, fuzzy-based indoor air quality index (fiaqi) t...

Background and Objectives: In recent years exposure to fine airborne particles has been identified as an important factor affecting human health. Epidemiological studies have showed that the aerosol laden air can be an agent for microorganisms’ dispersion. Ignoring internal sources, ambient air quality significantly affects indoor air quality. Since people spend most of their times in the indoo...

Introduction: Although epidemiological studies have reported an association between smoking and increases in tuberculosis the , relationship between indoor air pollution and risk of tuberculosis is not fully understood. A limited number of studies have suggested that smoking and indoor air pollution may play a role in the pathogenesis of tuberculosis. In this study, we investigated the effect o...
