With the marked increase in the awareness of indoor air quality (IAQ) issues, facility managers are under more pressure than ever to recognize and resolve IAQ problems. They must understand both the sources of these problems as well as the various methods for handling them. This document has been developed to help facility managers improve their understanding of IAQ issues and provide guidance ...

Inside IAQ is distributed twice a year and highlights indoor air quality (IAQ) research conducted by EPA’s National Risk Management Research Laboratory’s (NRMRL’s) Indoor Environment Management Branch (IEMB) and other parts of EPA’s Office of Research and Development. If you would like to be added to or removed from the mailing list, please mail, fax, or e-mail your name and address to; Inside ...

BACKGROUND Maternal smoking can cause health complications in pregnancy. Particulate matter (PM2.5) metrics applied to second hand smoke (SHS) concentrations provide indoor air quality (IAQ) measurements and have been used to promote smoking behaviour change among parents of young children. Here, we present the qualitative results from a study designed to use IAQ measurements to help pregnant w...

BACKGROUND Poor indoor air quality (IAQ) and psychosocial problems are common in schools worldwide, yet longitudinal research on the issue is scarce. We examined whether the level of or a change in pupil-reported school environment (IAQ, school satisfaction, and bullying) predicts recorded sick leaves among teachers. METHODS Changes in the school environment were assessed using pupil surveys ...

For healthcare centers, local outdoor sources of air pollution represent a potential threat to indoor air quality (IAQ). The aim of this study was to study the impact of local outdoor sources of air pollution on the IAQ of a university hospital. IAQ was characterized at thirteen indoor and two outdoor locations and source samples were collected from a helicopter and an emergency power supply. V...

BACKGROUND The complex hospital environment requires special attention to ensure healthful indoor air quality (IAQ) to protect patients and healthcare workers against hospital-acquired (nosocomial) infections and occupational diseases. The aim here is to recommend effective guidelines for the control and management of hospital IAQ. MATERIAL/METHODS The authors have done an extensive literatur...

The research represents the preliminary data of the monitoring of IAQ for improvement of Safety and Health Factor towards sustainable work environment in industry. The system were develop and using the computer application and the IAQ instrumentation such as IAQ meter and the TOXIC meter to getting the direct reading data. The data were transfer and evaluate by using the Visual Basic Software. ...

Indoor air quality (IAQ) is the problem that people increasingly pay attention to. With the development of Chinese railway undertaking, air-conditioned train is developing to the direction of higher speed and more comfortable. However, in China, people pay more attention to the temperature and the relative humidity in train compartments, but do not care for IAQ, so it leads to poor IAQ in train...

Effective and efficient ventilation is essential when improving energy performance and Indoor Air Quality (IAQ) of buildings. Reducing air permeability can considerably improve the energy performance of buildings; however, making the buildings more airtight may result in lower rates of natural ventilation which may in turn increase the risks of condensation and unacceptable IAQ. This study eval...
