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.

众所周知，复印机或激光打印机在运行时会释放出直径小于一微米的超细颗粒。我们评估了八名健康志愿者在常规操作条件下复印机吸入排放物对自主神经系统的影响。在复印机开始发射超细颗粒之前和之后，心率变异性或唾液中嗜铬粒蛋白-A的量没有显着差异。
