Colorimetric sensor arrays with a pre-oxidation method for gaseous analytes
… chlorocarbons) which are commonly found indoor are not especially reactive and are difficult to detect at low concentration by our colorimetric sensor array. To improve the array response, a disposable pre-oxidation technique has been developed in which a vapor stream is passed through an …

Determination and control of some pollutants in indoor environments
Unsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to …

Study of building material emissions and indoor air quality
… materials and furnishings emit a wide variety of indoor pollutants, such as volatile organic compounds (VOCs). At present, no accurate models are available to characterize material emissions and sorption under realistic indoor conditions. The objective of this thesis is to fill that gap. Using the …

Modeling contaminant exposure in a single-family house
… trends to reduce the risk of overexposure to indoor pollutants. In this study, occupational exposure to household contaminants in a single-family house with several ventilation, heating, and climactic conditions was simulated using CFD. Typical household exposure to CO2, CO, HCHO …

MEASUREMENTS OF ATMOSPHERIC RADICALS IN AMBIENT AND INDOOR ENVIRONMENTS: OUTDOOR-INDOOR RELATIONSHIPS, INDOOR FORMATION MECHANISMS, AND INSTRUMENTAL ANALYSIS
… ozone and secondary organic aerosols (SOA)—air pollutants affecting human health and welfare in ambient and indoor environments. In ambient environments with high mixing ratios of biogenic VOCs and low mixing ratios of NOx, measurements using our current instrumental technique for radicals have …

INDOOR AIR QUALITY AND ENERGY IMPLICATIONS IN THE USE OF VRV SYSTEM FOR OFFICE BUILDING
… of this work was to evaluate the impact of indoor air quality and energy implication on the usage of variable refrigeration volume (VRV) in the low-rise office environment. Two offices equipped with the VRV installation and employing two different modes of fresh air supply were selected for …

Emissions of Phthalate Plasticizer from Polymeric Building Materials
Modern indoor environments contain a vast array of contaminating sources. Emissions from these sources produce contaminant concentrations that are substantially higher indoors than outside. Because we spend most of our time indoors, exposure to indoor pollutants may be orders-of-magnitude greater …
