Ventilation and Concentrations

Abstract

Although most work on air pollution has focused on ambient (outdoor) concentrations, indoor environments are of most interest here. As shown in Figure 1.8, indoor pollutant concentrations are a function not only of the source strength but also of the characteristics of the building and the way it is used. It is important to understand these factors separately because their manipulation may be an effective means to reduce human exposures and ill health. Indeed, changes in building characteristics may be easier and less expensive to achieve in many circumstances than modifying stoves and fuels.
