| Outline of Final Research Achievements |
Metal oxide nanoparticles are widely used in industry, cosmetics, and biomedicine. However, the effects of exposure to these nanoparticles on the cardiorespiratory function remain unknown. The objective of this study was to survey workplace exposure levels and health effects of workers exposed to nano-TiO2 or nano-CaCO3. The study showed that exposure to particles with a diameter <300 nm might affect heart rate variability in workers handling TiO2 particles. The results highlight the need to investigate the possible impact of exposure to nano-scaled particles on the autonomic nervous system. In addition, long-term and high-leveled CaCO3 particles exposure can induce pulmonary hypofunction in workers. Thus, lung function examination is suggested for occupational populations with nano-CaCO3 exposure.
