| Research Abstract |
It is well recognized that photocopiers or laser printers emit ultra-fine particles in less than one micrometer diameter when they are operated. We evaluated the effect of inhaled emission of a photocopier machine under conventional operation condition on the autonomic nervous system in eight healthy volunteers. There was no significant difference either in heart rate variability or in chromogranin-A amount in saliva between before and after the emission of ultra-fine particles from the photocopier was started.
