enhance
the
repellency
of
other

was

C
MGK
®
Repellent
326
is
currently
classified
as
a
probable
human
carcinogen
(
B2)
based
on
the
findings
in
the
rat
and
the
mouse
studies.

Risks
C
Acute
and
chronic
dietary
(
food
and
drinking
water)
risks
are
not
of
concern,
because
dietary
exposure
from
use
as
an
insect
repellent
is
not
expected.

C
Residential
non­
cancer
risks
from
dermal
and
incidental
oral
exposure
is
not
of
concern.

C
Residential
cancer
risks
are
of
potential
concern
from
dermal
exposure
to
MGK
®
Repellent
326;
however,
the
Agency
considers
this
assessment
to
be
conservative.

C
Aggregate
(
food,
water,
&
residential)
risks
are
not
of
concern,
because
there
is
no
potential
for
concurrent
exposure
via
the
food,
water,
and
residential
pathways.

C
Worker
risks
are
not
of
concern,
because
there
are
no
specific
occupational
uses
of
MGK
®
Repellent
326.

C
Ecological
risks
are
not
of
concern.
The
Agency
believes
that
there
is
little
to
no
exposure
to
non­
target
organisms
and
endangered
species
from
the
registered
uses.
