An emissions barrier was used in premises with indoor air complaints due to emissions from the buildings in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood, and volatile organic compounds (VOC), mainly 2-ethylhexanol, from PVC flooring and the glue used to paste the flooring onto a concrete slab. Attaching the barrier at the surfaces from where the emissions were spread (floor, walls, ceiling) resulted in a fresh and odour-free indoor air. We conclude that using an emissions barrier in buildings made unhealthy by moisture is an efficient way of restoring a pleasant and healthy indoor air.

Abstract The photocatalytic oxidation of seven typical indoor volatile organic compounds (VOCs) is experimentally investigated using novel nanocrystalline TiO2 dip-coated catalysts. Not only the role of hydrophilicity of the reactants but also other physico-chemical properties and molecular descriptors are studied and related to kinetic and equilibrium constants. The main objective of this work consists in establishing simple relationships that will be useful to deepen the understanding of gas-phase heterogeneous photocatalytic mechanisms and for the prediction of degradation rates of these VOCs using an indoor air treatment process.

Volatile Organic

Abstract The indoor environment can constitute a serious health hazard if buildings are not properly constructed and finished. Building, finishing and furnishing materials may emit a large number of volatile organic compounds (VOCs) into the indoor air. That wood-composite products are among the sources of formaldehyde emissions is well documented. Up until now very little has been known about the emission of VOCs from wood-composite products (Merrill and Steiber 1987; Levin 1992; Sundin and Edenholm 1992; Catananti et al. 1993; Barry and Corneau 1999). The aim of this work is the determination of VOC and formaldehyde emissions from particleboard veneered with decorative paper foil.

Catalytic Deactivation

AbstractGas-phase photocatalytic oxidation of different classes of volatile organic compounds (VOCs), including alkanes, ketones, alcohols, chlorinated compounds and aromatic compounds, was investigated using an annular thin film reactor. For all organic compounds tested, catalytic deactivation was not observed, except for toluene (506 ppmv). For this compound, maximum destruction (87%) was maintained during the first 60 min of irradiation, dropping steadily due to catalyst deactivation to 20% after 150 min. The use of ozone as auxiliary agent in the photocatalytic oxidation of toluene and pyridine was also tested. For toluene, when O
