High uptake rate radial diffusive sampler suitable for both solvent and thermal desorption
1996 - Cocheo, V., Boaretto, C., Sacco P.
A new diffusive sampler with radically changed diffusive path geometry was developed. The small cylinder has a height greater than its radius; the diffusive surface is the external cylindrical one, and the adsorber is a coaxial inner cylindrical cartridge. Due to the high value of diffusive area-path length ratio and to the high loading capacity… View Article
Ambient volatile organic compounds monitoring by diffusive sampling. Compatibility of high uptake rate samplers with thermal desorption
1997 - Bates, M., Gonzalez-Flesca, N., Cocheo, V., Sokhi, R.
Field and laboratory validation studies were carried out on a novel, high uptake rate, radial diffusive sampler loaded with Carbotrap, a thermally desorbable adsorbent. For field experiments parallel techniques were employed for comparison. The goal was to assess the compatibility of the device for subsequent thermal desorption and preconcentration of the sample for analysis. Some… View Article
Benzene exposure assessment at indoor, outdoor and personal levels. The French contribution to the Life MACBETH Programe
2000 - Gonzalez-Flesca N., Bates M.S., Delmas V., Cocheo V.
Many VOC represent hazards to human health through chronic exposure. Recent European and world-wide legislation proposes limit values for ambient concentrations of these compounds. However, very little experimental data exists for true population exposure. In 1996, the European MACBETH initiative set out to measure population exposure to benzene in six European cities. This study details… View Article
Atmospheric volatile organic compound monitoring. Ozone induced artefact formation
2000 - Bates M.S., Gonzalez-Flesca N., Sokhi R., Cocheo V.
Assessment of population exposure to VOC in ambient atmospheres is receiving heightened interest as the adverse health effects of chronic exposure to certain of these compounds are identified. Active (pumped) and passive samplers are the most commonly used devices for this type of monitoring. It has been shown, however, that these devices, along with all… View Article
Exposure to benzene in urban workers: environmental and biological monitoring of traffic police in Rome
2001 - Crebelli, R., Tomei, F., Zijno, A., Ghittori, S., Imbriani, M., Gamberale, M., Martini, A., Carere A.
OBJECTIVES To evaluate the contribution of traffic fumes to exposure to benzene in urban workers, an investigation on personal exposure to benzene in traffic police from the city of Rome was carried out. METHODS The study was performed from December 1998 to June 1999. Diffusive radiello® personal samplers were used to measure external exposures to… View Article
An overview of commonly used methods for measuring benzene in ambient air
2001 - Skov, H., Lindskog, A., Palmgren, F., Christensen, C.S.
Emitted primarily from traffic, benzene has been identified as a carcinogen, inflicting deleterious effects on human health. This has mandated a high degree of scientific attention, both to measure ambient levels in urban regions and to explore mitigation strategies, which can form the basis of policy. In this paper, we present an overview of the… View Article
Benzene exposure and the effect of traffic pollution in Copenhagen, Denmark
2001 - Skov, H., Hansen, A.B., Lorenzen, G., Andersen, H.V., Løfstrøm, P., Christensen, C.S.
Benzene is a carcinogenic compound, which is emitted from petrol-fuelled cars and thus is found ubiquitous in all cities. As part of the project Monitoring of Atmospheric Concentrations of Benzene in European Towns and Homes (MACBETH) six campaigns were carried out in the Municipality of Copenhagen, Denmark. The campaigns were distributed over 1 year. In… View Article
Human exposure to traffic pollution. Experience from Danish studies
2001 - Hertel, O., Jensen, S.S., Andersen, H.V., Palmgren, F., Wåhlin, P., Skov, H., Nielsen, I.V., Sørensen, M., Loft, S. and Raaschou-Nielsen, O.
Air pollution may have severe long-term as well as short-term health effects. The determination of possible links between pollution levels and impact on human health is, however, not a straightforward task. A key problem is the assessment of human exposure to ambient pollution levels. In later years, the possible role of particulate pollution as a… View Article
Air quality in major Portuguese urban agglomerations
2002 - Ferreira, F., Tente, H., Torres, P.
This paper presents some recent research work that has been developed for the major Portuguese agglomerations. Three main topics are developed: the methodology used in Portugal to limit agglomerations (as they are defined by the European Air Quality Framework Directive 96/62/EC), the preliminary assessment of the air quality levels in the most densely populated agglomerations… View Article

Anaesthetic gases and vapours: the sampling rate, experimentally measured, for desflurane is now available. Radiello codice RAD 132
Radiello is now available for the sampling of 1,3-butadiene and isoprene.
14 October 2019
1,3-butadiene and isoprene are trapped by adsorption, recovered by thermal desorption and analysed by capillary gas chromatography with MS detector. The LOQ for 8-hour workplace exposure is 0.3 μg·m-3. For a 7-day exposure to ambient air, the LOQ is 0.01 μg·m-3. radiello code RAD 141
