Tielemans, E. Skarping, G. Bobeldijk, I. van Hemmen, J. Heederik, D. Preller, L. TNO Kwaliteit van Leven Publication year 2006 Abstract As part of a large-scale epidemiological study, occupational isocyanate exposure was assessed in spray-painting environments. The aim was to assess which compounds contribute to isocyanate exposure in car body repair shops and industrial painting companies, and to identify tasks with high risk of isocyanate exposure. Mainly personal task-based samples (n = 566) were collected from 24 car body repair shops and five industrial painting companies using impingers with DBA in toluene. Samples were analysed by LC-MS for isocyanate monomers, oligomers and products of thermal degradation. From the 23 analysed compounds, 20 were detected. Exploratory factor analysis resulted in a HDI, TDI and MDI factor with the thermal degradation products divided over the TDI and MDI factors. The HDI factor mainly consisted of HDI oligomers and was dominant in frequency and exposure levels in both industries. Spray painting of PU lacquers resulted in the highest exposures for the HDI factor ( Subject HealthFood and Chemical Risk AnalysisIsocyanateOccupational exposureOligomersSpray paintingThermal degradationEpidemiologyGround vehiclesOccupational diseasesOccupational risksOligomersPaint sprayingPersonnelPyrolysisCar body repair shopsImpingersIsocyanateNitrogen compoundsisocyanic acid derivativeoligomeraerosolcomparative studyexploratory behaviorhigh risk populationindustrial workerpaint industrypainterpaintingsamplethermal injuryworkerAir Pollutants, OccupationalAutomobilesEnvironmental ExposureEnvironmental MonitoringFactor Analysis, StatisticalHumansIndustryInhalation ExposureIsocyanatesOccupational ExposurePaintWork To reference this document use: http://resolver.tudelft.nl/uuid:69817923-75b6-4b9a-bc18-9b8b25a11227 DOI https://doi.org/10.1093/annhyg/mei044 TNO identifier 239071 ISSN 0003-4878 Source Annals of Occupational Hygiene, 50 (1), 1-14 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
