Determining indoor air quality and identifying the origin of odour episodes in indoor environments

Abstract

Abstract. A methodology for identifying volatile organic compounds (VOC) and15 determining air quality in indoor air has been developed. The paper standardizes the 16 procedure of sampling and analysis for low concentration VOC air samples in buildings. 17The methodology is based in the activation of pump samplers by the inhabitants of the The concentrations of some individual VOC (ethanol, acetone, isopropanol, 1-butanol, 31 acetic acid, acetonitrile and 1-metoxy-2-propanol) were also higher than the expected

Determination of the biogenic secondary organic aerosol fraction in the boreal forest by NMR spectroscopy

“…Nonetheless positive artefacts or accidental contaminations during the sampling cannot be definitely ruled out. In fact, glycol ethers are chemicals commonly used in paints and ethylene glycol butyl ether (butoxy ethanol) was identified among other VOCs of toxicological interest in urban areas (Gallego et al, 2009). If not laboratory contaminants, they may have originated from a local source at the sampling site or nearby.…”

Toluene photocatalytic oxidation at ppbv levels: Kinetic investigation and carbon balance determination

“…Volatile organic compounds (VOC) represent the major group of indoor air contaminants [2]. Sources of VOC have been attributed to outdoor air, cooking, carpets, desks, paintings, ceilings [3,4], for instance. Concentrations of VOC can build up because of the low turnover rate of air in modern buildings sealed by high efficiency thermal insulation devices.…”

Indoor Air Quality

“…5 Chemical pollutant concentrations have been found to contribute to sick building syndrome. 6 Higher total VOC levels were detected in indoor air (1.33 ± 1.53 mg/m 3 ) than in outdoor air (0.71 ± 0.46 mg/m 3 ). 6 Ethanol, acetone, isopropanol, 1-butanol, acetic acid, acetonitrile, and 1-methoxy-2-propanol were determined in indoor air.…”
