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 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.

Rhynchophorus palmarum es plaga relevante en palmeras (Arecaceae) en Brasil. Su respuesta comportamental (olfatometría) y electrofisiológica (electroantenografía, sola y acoplada a cromatografía) se estudió frente a compuestos orgánicos volátiles emitidos por hongos entomopatógenos nativos aislados en Coruripe (Alagoas, Brasil) mediante aireación durante 24 horas. El aislado CVAD01 no originó respuesta comportamental significativa, pero el CVAD02 originó atracción significativa en machos. Los bioensayos electrofisiológicos mostraron actividad antenal en los dos sexos de R. palmarum frente a los componentes volátiles de los extractos de los dos hongos identificados. Los análisis cromatográficos de los extractos indicaron perfiles de compuestos orgánicos volátiles con la presencia de dos alcoholes, tres hidrocarburos aromáticos, dos monoterpenos, tres cetonas y tres hidrocarburos lineales. Rhynchophorus palmarum is a major pest of palms (Arecaceae) in Brasil. Both the behavioral (olfactometry) and electrophysiological (electroantennography, both alone and coupled to chromatography) was studied against volatile organic compounds emitted by native entomopathogenic fungi isolated from Coruripe (Alagoas, Brazil). Fungal isolates were identified by aeration system for 24 hours. CVAD01 did not cause a significant behavioral response; however, males were significantly attracted to CVAD02 extracts. Electrophysiological bioassays showed antennal activity, in both sexes, to volatile components of the two identified native fungi. The chromatographic analysis of the extracts indicated profiles of volatile organic compounds with the presence of three alcohol, three aromatics, three ketones, and four hydrocarbons.
