Indoor air pollution has been causally linked to acute lower respiratory infections in children younger than 5. The aim of this study was to identify target behaviors for a behavioral intervention to reduce child exposure to indoor air pollution by attempting to answer two research questions: Which behaviors are protective of child respiratory health in the study context? and Which behaviors do...
We study the effect of outdoor air pollution on the productivity of indoor workers at a pear-packing factory. Increases in fine particulate matter (PM2.5), a pollutant that readily penetrates indoors, leads to significant decreases in productivity, with effects arising at levels below air quality standards. In contrast, pollutants that do not travel indoors, such as ozone, have little, if any, ...
A simultaneous study on indoor and outdoor particulate matter concentrations was done in five elementary schools in central parts of Tehran, Iran. Three sizes of particles including PM10, PM2.5 and PM1.0 were measured in 13 classrooms within this schools during winter (January, February and March) 2009. A laserbased portable aerosol spectrometer Model Grimm-1.108, was used for the continuous me...
INTRODUCTION The present study examined indoor air quality in a global sample of smoke-free and smoking-permitted Irish pubs. We hypothesized that levels of respirable suspended particles, an important marker of secondhand smoke, would be significantly lower in smoke-free Irish pubs than in pubs that allowed smoking. METHODS Indoor air quality was assessed in 128 Irish pubs in 15 countries be...
BACKGROUND The association between ambient air pollution and heart rate variability (HRV) has been well-documented. Little is known about the association of HRV at night with indoor air pollution and coffee consumption. The aim of this study was to investigate the association of HRV indices with indoor air pollution, working time and coffee consumption. METHODS We recruited 60 young healthy c...
One largely unstudied benefit of relocating families from slums to public housing is the potential improvement in indoor air quality (IAQ). We compared families that moved from slums to public housing with those that remained living in slums in Santiago, Chile in terms of fine particulate matter (PM2.5) as main indicator of change. A cross-sectional study of 98 relocated families and 71 still l...
This chapter summarizes the methodology used to assess the burden of disease caused by indoor air pollution from household use of solid fuels. Most research into and control of indoor air pollution worldwide has focused on sources of particular concern in developed countries, such as environmental tobacco smoke (ETS), volatile organic compounds from furnishings and radon from soil. Although the...
Background and Aim: One of the notorious air pllutants on which air quality is determined is carbon monoxide (CO). The aim of the present study was to measure the concentration of CO outdoor and indoor urban environments and compare it with air quality standards within buildings and open spaces. Materials and Methods: This research was a descriptive-analytical study of CO estimation in ou...
BACKGROUND Exposure to indoor air pollution may be responsible for nearly 2 million per year deaths in developing countries. In Kenya, it is among the factors linked to high morbidity, especially in children aged below five years. OBJECTIVES The survey was conducted in 2005 in 350 rural households to identify household factors that are likely to enhance indoor air pollution. METHODS Questio...
OBJECTIVE Nearly all China's rural residents and a shrinking fraction of urban residents use solid fuels (biomass and coal) for household cooking and/or heating. Consequently, global meta-analyses of epidemiologic studies indicate that indoor air pollution from solid fuel use in China is responsible for approximately 420,000 premature deaths annually, more than the approximately 300,000 attribu...
