Nitrogen
dioxide
is a
yellowish-brown
gas
with
a
characteristic
pungent,
acrid
odor.
Nitrogen
dioxide
is
soluble
in
water
at
which
time
it
reacts
to
form
nitric
acid.
NO2
can
be
found
in
industries
where
the
burning
of
diesel
fuel
takes
place.
The
most
toxic
component
in
diesel
emissions
is
nitrogen
dioxide.
Nitrogen
dioxide
exposure
in
low
doses
can
cause
irritation
of
the
eyes
and
throat,
headache,
nausea,
and
gradual
loss
of
strength.
High
doses
of
NO2
can
cause
pulmonary
edema
(water
in
the
lungs)
and
death.
