.2.5 Effects of Carbon Monoxid
When inhaled, Carbon Monoxide is absorbed b
the
lun
s and reacts with the blood hemo
lobin to
orm
arbon hemo
lobin, which reduces the ox
en carr
in
apacit
of the blood. The result is a lack of ox
en
or the tissues, causin
subsequent tissue death and, i
prolon
ed, death o
the individual.
arbon Monoxide in
hi
h concentrations can be fatal in a matter of minutes.
ven lower concentrations must not be i
nored because
the a
ects o
exposure to
are cumulative and can
be
ust as lethal. Certain health related problems and
a
e increases the e
ects o
. People who smoke or
