Carbon monoxide (CO) was clearly identified in gas that emanated from human skin and is called skin gas. It was collected by covering the skin surface of the subject’s hand with a poly (vinyl fluoride) bag for 10 minutes and then analyzed by a GC with a semiconductor gas sensor. It was proved that CO was emanated from the human skin of six healthy volunteers. The emanated CO amounts from the hands for 10 min were 8.1 ± 4.2 ng. Furthermore, CO in skin gas correlated with that from the breath at a level of r = 0.68.
