Validation of a measurement method for diacetyl using sorbent tubes and thermal desorption
Diacetyl, also known as 2,3-butanedione, and the closely related chemical 2,3-pentanedione, are naturally occurring substances with a characteristic butter-like odour found in foods such as dairy products, beer and fruits. Diacetyl is also added to various food products as artificial butter flavouring and both substances are present in emissions generated by coffee roasting and grinding. Occupational levels of diacetyl exposure has been linked with the lung disease bronchiolitis obliterans which is life threatening and irreversible. In Great Britain, occupational exposure limits to protect workers'...
Respiratory morbidity in a coffee processing workplace with sentinel obliterative bronchiolitis cases
Rationale: Obliterative bronchiolitis in former coffee workers prompted a cross-sectional study of current workers. Diacetyl and 2,3-pentanedione levels were highest in areas for flavoring and grinding/packaging unflavored coffee. Methods: We interviewed 75 (88%) workers, measured lung function, and created exposure groups based on work history. We calculated standardized morbidity ratios (SMRs) for symptoms and spirometric abnormalities. We examined health outcomes by exposure groups. Results: SMRs were elevated 1.6-fold for dyspnea and 2.7-fold for obstruction. The exposure group working in both...
Éléments techniques sur l’exposition professionnelle à cinq solvants ou familles de solvants oxygénés aliphatiques
Ce guide présente les matrices emplois-expositions à cinq solvants ou familles de solvants oxygénés ainsi qu'à au moins une de ces cinq familles, développées par le Département santé travail (DST) de l'Institut de veille sanitaire (InVS) et l'Unité mixte de recherche épidémiologique et de surveillance en transport, travail et environnement (Umrestte). Ces matrices permettent une vision d'ensemble de l'utilisation de ces solvants en France de 1950 à 2012. Pour tous les emplois considérés...
