As
part
of
the
Office
of
Pesticide
Program's
reregistration
review
of
methyl
bromide
the
potential
impacts
on
stratospheric
ozone
depletion
and
the
related
human
cancer
risk
via
ozone
depletion
is
being
assessed
for
the
United
States.
Methyl
bromide
is
a
stratospheric
ozone
depleting
substance.
This
reduction
in
stratospheric
ozone
allows
more
ultraviolet
radiation
to
reach
the
earth's
surface
which
in
turn
can
lead
to
increased
rates
of
skin
cancer.
As
model
inputs
to
this
assessment,
BEAD
estimated
the
methyl
bromide
usage
in
the
U.
S.
for
2004
based
on
information
from
the
methyl
bromide
critical
use
exemption
process,
US
Department
of
Agriculture,
Animal
and
Plant
Health
Inspection
Service,
and
EPA
proprietary
sources.
Based
on
these
sources
BEAD
estimates
there
were
a
total
of
23
million
pounds
of
methyl
bromide
used
in
the
U.
S.
in
2004
with
3
million
pounds
used
on
commodities,
food
processing
facilities,
and
food
quarantine
uses,
and
20
million
pounds
used
on
all
other
sites.
