The exposure of children to air pollution in low resource settings is believed to be high because of the common use of biomass fuels for cooking. We used microenvironment sampling to estimate the respirable fraction of air pollution (particles with median diameter less than 4 μm) to which 7-9 year old children in southern Nepal were exposed. Sampling was(More)
paper presents the work carried out in developing a precision, bolus injection system to study the effect of regional deposition of fine particulate matter (PM) within the human respiratory system and to investigate the optimal conditions for inhaled drug delivery. In contrast to existing methods, the new system computes parameters necessary and injects PM(More)
Household Air Pollution (HAP) from biomass cooking fuels is a major cause of morbidity and mortality in low-income settings worldwide. In Nepal the use of open stoves with solid biomass fuels is the primary method of domestic cooking. To assess patterns of domestic air pollution we performed continuous measurement of carbon monoxide (CO) and particulate(More)
precision, bolus injection system to study the effect of regional deposition of fine particulate matter (PM) within the human respiratory system and to investigate the optimal conditions for inhaled drug delivery. In contrast to existing methods, the new system computes parameters necessary and injects PM into breath cycles by a process of dynamic breath(More)
