Abstract:
The concentrations of isoprene, the main hydrocarbon of human breath, were measured in the blood of humans and of different animal species (rat, rabbit, dog, ewe, cow). In human blood, the concentrations of isoprene were between 15 and 70 nmol/liter (mean value of 37 +/- 25 (SD) nmol/liter). In the blood of the different animal species tested, traces of isoprene were unambiguously detected by mass spectrometry, but the levels were always lower than 1 nmol/liter.
