In-plant measurement of aerosol nanoparticles and determination of workers‘ exposure

DACP has been cooperating with the Department of Occupational Medicine, 1st Faculty of Medicine, Charles University in Prague, and the Technical University of Liberec since 2015 to determine the acute and chronic effects of nanoparticle inhalation in nanoparticle manufacturing workers. Over the monitoring period, more than 10 impactful papers have been published, describing the effects of inhaled metal oxide nanoparticles (e.g. TiO2) and a variety of composite materials on upper respiratory tract inflammation, and impairment of metabolism of fats, proteins, and nucleic acids. Chronic studies indicate that the effect of these particles on the human organism is statistically significant and in some cases irreversible. In all these studies, DACP is involved in the development and application of methods to determine workers’ real exposure to aerosol particles. The published results have been widely cited by the international scientific community.
