pollutant

This paper describes a pilot study conducted in an occupied family house in Ohio to determine if a script-based protocol could be used to obtain data useful for the identification of the key factors affecting air-exchange rate (AER) and the relationship between indoor and outdoor concentrations of selected traffic-related air pollutants.

An optimal placement of outside air intakes is important for a good IAQ protection. A proper intake placement can also reduce the need for filtration, and reduce re-entrainment of chemical emissions.

The IAQ characteristics and the corresponding health symptoms and thermal sensation of the occupants of child care centers in Singapore under 3 different ventilation strategies are reported. The 3 child care centers studied were centrally air-conditioned and mechanically (ACMV) ventilated (Case A), naturally ventilated (Case B) and hybrid (natural and air-conditioning) ventilated (Case C).

The key principle of this work is that intermittent ventilation is equivalent to continuous ventilation if the pollutant exposure to an individual in the space is the same in both cases.

This study surveyed concentrations of airborne AP (alkyphenols) in indoor air and outdoor air in Tokyo. An analytical method has been developed using the gas chromatography/mass spectrometry-SIM.

The second part of the VIP Indoor air pollutants concerns the sources of pollutants and effective measures to control them or to make their impact on occupants less severe.

The author describes the most important indoor air related health determinants and a table gives information on the source characterisation of health determinants indoors, their control method along with examples of actions that could be taken by national level bodies or societies.

This paper is a review of data collected in European dwellings on particulate matter (PM), nitrogen dioxide (NO2), carbon dioxide (CO2), carbon monoxide (CO), volatile organic compounds (VOCs), formaldehyde, dampness/mould and dust mites at home. Related health effects are summarized in this review too, along with some results not yet published from two Italian indoor air studies.

For that study, 200 children in Manchester were recruited to assess their asthma status, their indoor environment was analyzed. Levels of a variety of indoor agents, reported as important factors in the development or the exacerbation of respiratory troubles were examined. Results are presented.

This paper provides an overview of existing guidance, regulations, and design approaches to control diesel exhaust from locomotives operating in buildings. First, design guidance and standards for exposure to major components of diesel exhaust are reviewed. Next, issues regarding engine design, fuel composition, and outdoor emissions control strategies and their potential impact on current and future indoor emissions are discussed. Ventilation approaches that have been implemented in existing facilities are also presented.
