Utilisation des composés organiques volatils microbiens comme biomarqueurs de l'exposition aux moisissures en milieu de travail ? Étude de faisabilité
La problématique de la qualité de l'air est un aspect important de la santé et de la sécurité au travail. Les moisissures et leurs composés sont des contaminants auxquels les travailleurs peuvent être exposés. Ces microorganismes sont responsables de nombreux problèmes de santé (maladies ou inconforts), incluant des allergies aiguës, de l'asthme, des sinusites/rhinites, des céphalées, de l'hypersensibilité environnementale, des irritations et des inflammations. La surveillance classique de...
Isocyanate Exposure Assessment Combining Industrial Hygiene Methods with Biomonitoring for End Users of Orthopedic Casting Products
Previous studies have suggested a potential risk to healthcare workers applying isocyanate-containing casts, but the authors reached their conclusions based on immunological or clinical pulmonology test results alone. We designed a study to assess potential exposure to methylene diphenyl diisocyanate (MDI) among medical personnel applying orthopedic casts using two different application methods. Air, dermal, surface, and glove permeation sampling methods were combined with urinary biomonitoring to assess the overall risk of occupational asthma to workers handling these materials. No MDI was detected...
Comparative Emissions of Random Orbital Sanding between Conventional and Self-Generated Vacuum Systems
Conventional abrasive sanding generates high concentrations of particles. Depending on the substrate being abraded and exposure duration, overexposure to the particles can cause negative health effects ranging from respiratory irritation to cancer. The goal of this study was to understand the differences in particle emissions between a conventional random orbital sanding system and a self-generated vacuum random orbital sanding system with attached particle filtration bag. Particle concentrations were sampled for each system in a controlled test chamber for oak wood, chromate painted (hexavalent...
