Occupational exposure to benzene, toluene, xylene and styrene and risk of prostate cancer in a population-based study
Objectives: While several monocyclic aromatic hydrocarbons are classified as definite or possible carcinogens to humans, little data exist on their role in prostate cancer (PCa). We examined occupational exposure to benzene, toluene, xylene (BTX) and styrene and PCa risk in a population-based case–control study in Montreal, Canada. Methods: Cases aged ≤75 years diagnosed with PCa in 2005–2009 (n=1920) and population controls frequency-matched on age (n=1989) provided detailed work histories. Experts evaluated the certainty, frequency and concentration of exposure to monocyclic aromatic...
Mise en oeuvre manuelle des polyesters stratifiés
Cette brochure est conçue comme un guide et un document de référence pour la conception, la réception, la conduite et le contrôle des installations de ventilation dans un atelier de polyesters stratifiés. Dans ce guide pratique de ventilation, sont abordés les points suivants : - Généralités sur les matières premières, le niveau de risque, le polluant principal (styrène), le moulage au contact. - Méthodologie d'étude du système de ventilation. - Conception du système de ventilation...
Maternal occupational exposure to polycyclic aromatic hydrocarbons and small for gestational age offspring
Objectives: While some of the highest maternal exposures to polycyclic aromatic hydrocarbons (PAHs) occur in the workplace, there is only one previous study of occupational PAH exposure and adverse pregnancy outcomes. We sought to extend this literature using interview data combined with detailed exposure assessment. Methods: Data for 1997–2002 were analysed from mothers of infants without major birth defects in the National Birth Defects Prevention Study, a large population-based case-control study in the USA. Maternal telephone interviews yielded information on jobs held in the month before...
Occupational exposure to solvents and acute myeloid leukemia
A population-based, case–control study in four Nordic countries Objective: The aim of the current study was to assess the relation between occupational exposure to solvents and the risk of acute myeloid leukemia (AML). Methods: Altogether, this study comprises 15 332 incident cases of AML diagnosed in Finland, Norway, Sweden and Iceland from 1961–2005 and 76 660 controls matched by year of birth, sex, and country. Occupational records were linked with Nordic Occupational Cancer Study job exposure matrix (JEM) to estimate quantitative values for 26 occupational exposure factors. Hazard...
Urinary S-phenylmercapturic Acid as a Key Biomarker for Measuring Occupational Exposure to Low Concentrations of Benzene in Chinese Workers
A Pilot Study Objective: This study analyzed the level of urinary S-phenylmercapturic acid (U-SPMA) for low benzene exposure in a group of Chinese shoe-making workers. Methods: Urinary samples from 55 workers exposed to benzene at levels lower than 10 parts per million (ppm) were collected at postshift. U-SPMA level was determined using high-performance liquid chromatography/mass spectrography (HPLC/MS) method. Results: Good linearity of U-SPMA was observed within the range from 10 to 320 μg/L (r = 0.9994). Concentration of airborne benzene ranged from 0.71 to 32.17 mg/m3, and three segments...
Effets des pics de concentration sur la neurotoxicité du styrène dans l’industrie de plastique renforcé de fibre de verre
Le projet de recherche avait deux objectifs principaux. D'une part, nous voulions faire des mesures en continu dans les milieux de travail pour bien connaître les profils d'exposition des travailleurs de l'industrie du plastique renforcé de fibre de verre (IPRFV). D'autre part, nous voulions savoir s'il est possible que de « fortes » expositions pendant de courtes périodes de temps, les « pics », puissent avoir un effet sur le système nerveux des travailleurs.
