Conclusions
Quantitative analysis of acetylene was made possible in blood
and urine samples by the present method. This method showed
good reliability, and is also simple and rapid. In acetylene explosion
cases, the quantification of acetylene in blood and/or urine
from cadavers gives important information, because the acetylene
concentration is a vital reaction or sign. For example, when acetylene
is filled in a closed space and then explodes, in antemortem
explosion, the blood acetylene concentration of the cadaver might
be significant. On the other hand, in postmortem explosion, acetylene
is not detected in blood. Furthermore, when several victims are
involvedin one explosion,comparison of thesample concentrations
can also provide useful information to establish the conditions at
the accident scene.
