In the present research, performance validation of a Heating, Ventilation, and Air Conditioning (HVAC) system operating in a library building was conducted. The operating HVAC system was studied in terms of the provided indoor air conditions and energy consumption level. The fieldwork measurements showed that the HVAC system is not capable of providing the desired indoor air conditions based on...
Increasing attention has been focused on the health effects of urban transport in recent years. This report highlights the framework in which integrated assessment of the effects of urban transport on health can be carried out. The discussion is based on the results of a research project called HEARTS (health effects and risks of transport systems) conducted as part of the Fifth Framework Progr...
OBJECTIVES In Bangladesh, second-hand smoke (SHS) is recognised as a principal source of indoor air pollution and a major public health problem. However, we know little about the extent to which people are aware of the risks of second-hand smoking, or restrict smoking indoors or in the presence of children. We report findings of a community survey exploring these questions. DESIGN AND SETTING...
Asthma is common in children worldwide, although its prevalence varies substantially by location. The prevalence of wheeze over a 12-month period ranged from 2.1% to 32.2% in the older age group (13–14 years) and 4.1% to 32.1% in the younger age group (6–7 years) [1]. There is a positive association between current symptoms of asthma in younger and older children with gross national income [2],...
OBJECTIVE To evaluate indoor air pollution in hospitality venues in Argentina. MATERIAL AND METHODS PM₂.₅ levels were measured in a convenience sample of venues in 15 cities with different legislative contexts following a protocol developed by Roswell Park Cancer Institute. RESULTS 554 samples were collected. Across all 5 smoke free cities the mean PM₂.₅ level was lower during daytime vs. e...
BACKGROUND To meet the current diversified health needs in workplaces, especially in nonindustrial workplaces in developing countries, an indoor air quality (IAQ) component of a participatory occupational safety and health survey should be included. OBJECTIVES The purpose of this study was to evaluate and suggest a multidisciplinary, integrated IAQ checklist for evaluating the health risk of ...
Alternative cook stoves that replace solid fuels with cleaner energy sources, such as biogas, are gaining popularity in low-income settings across Asia, Africa, and South America. Published research on these technologies focuses on their potential to reduce indoor air pollution and improve respiratory health. Effects on other cooking-related aspects, such as diets and women's time management, a...
Air pollution is among the leading global risks for mortality and responsible for increasing risk for chronic diseases. Community perceptions on exposure are critical in determining people's response and acceptance of related policies. Therefore, understanding people' perception is critical in informing the design of appropriate intervention measures. The aim of this paper was to establish leve...
BACKGROUND/AIMS The current study was designed to determine whether the indoor air pollution in a hemodialysis room (HD) was different from that of other comparable areas in a hospital. METHODS Five air monitor samplers were hung on the ceiling and placed on the table in both the HD and general ward nursing stations, respectively. In addition, five samplers were placed in the nurse's breathin...
the natural ventilation is an easy way to exchange the indoor polluted warm air with outdoor fresh air. the wind power injects outdoor fresh air into the building. a good indoor air current and subsequently a proper exhaust depend on the openings’ conditions and their situations. a serious architectural question is under what conditions of the openings the wind-cross ventilation can be effectiv...
