摘要: The aims of this study were to determine implications inter- and intraindividual variation in exposure respirable (quartz) dust heterogeneity characteristics for epidemiologic research construction workers. Full-shift personal measurements (n = 67) from 34 workers collected. between-worker day-to-day variances quartz estimated using mixed models. Heterogeneity was evaluated by electron microscopic analysis spin resonance. A grouping strategy based on job title resulted a 2- 3.5-fold reduction expected attenuation hypothetical exposure-response relation exposure, respectively, compared an individual approach. Material worked explained most the variance exposure. However, risk assessment epidemiology, materials they work is not practical. Mic...
