indoor environment. The most important include indoor pollutants, outdoor pollutants near the building, pollution transport through the ventilation system, air cleaning or filtration, and indoor climate (temperature and relative humidity). Many building materials, the furnishings and equipment, and the occupants and their activities are sources of indoor pollution. Following is a list of some o...

Indoor air pollution (IAP) is a key contributor to the global burden of disease mainly in developing countries. The use of solid fuel for cooking and heating is the main source of IAP in developing countries, accounting for an estimated 3.5 million deaths and 4.5% of Disability-Adjusted Life Years in 2010. Other sources of IAP include indoor smoking, infiltration of pollutants from outdoor sour...

BACKGROUND Tobacco smoking, passive smoking, and indoor air pollution from biomass fuels have been implicated as risk factors for tuberculosis (TB) infection, disease, and death. Tobacco smoking and indoor air pollution are persistent or growing exposures in regions where TB poses a major health risk. We undertook a systematic review and meta-analysis to quantitatively assess the association be...

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...

The sol-gel process is a wet-chemical technique (chemical solution deposition), which has been widely used in the fields of materials science, ceramic engineering, and especially in the preparation of photocatalysts. Volatile organic compounds (VOCs) are prevalent components of indoor air pollution. Among the approaches to remove VOCs from indoor air, photocatalytic oxidation (PCO) is regarded ...

Recent air pollution incidents in Chinese cities prompted this study, which makes use of air particulate monitoring information being submitted by volunteer-owned equipment to a public website. As an indicator of severe air pollution spikes, such as those seen in February 2014, the daily average readings for all monitoring locations were mapped and animated as a time series. Figure 1: China air...

This paper proposes an integrated ecological, economic and social model to assist sustainable rural development in villages in Bangladesh. In the model, renewable energy technologies (RETs) create income-generating activities for male landless and marginal farmers and for women from such households, while reducing environmental problems, like deforestation and indoor air pollution from cooking ...

BACKGROUND While any type of field-based research is challenging, building action-oriented, participatory research in resource-constrained settings can be even more so. OBJECTIVE In this article, we aim to examine and provide insights into some of the practical challenges that were faced during the course of a participatory project based in two non-notified slums in Bangalore, India, aiming t...

A knowledge-based system is presented that has been developed to be used as an advisor in the preliminary design stage of HVAC systems. It enables designers to configure and size HVAC equipment for different climatic conditions, in terms of building type, indoor requirements, outdoor and indoor air pollution. A new approach has been used in building the system, using a modified knowledge engine...
