D.
Cumulative
Effects
BASF
has
considered
the
potential
for
cumulative
effects
of
dimethenamid
and
other
substances
that
have
a
common
mechanism
of
toxicity.
BASF
is
aware
of
several
other
chloroacetanilide
herbicides
that
have
been
considered
structurally
similar
to
dimethenamid,
these
being:
Acetochlor,
propachlor,
butachlor,
metolachlor,
and
alachlor.
However,
BASF
believes
that
consideration
of
a
common
mechanism
of
toxicity
to
these
products
is
not
appropriate
or
valid.
This
conclusion
was
based
on
the
presentation
EPA
made
to
the
EPA
FIFRA
Science
Advisory
Panel
(
SAP)
on
March
20,
1997.
The
title
of
the
presentation
was
``
Grouping
of
Chloroacetanilide
Pesticides
Based
on
a
Common
Mechanism
of
Toxicity.''
In
this
presentation
EPA
showed
the
structure
of
several
chloroacetanilides
that
included
dimethenamid.
BASF
is
identifying
Chlor
 
7
as
dimethenamid.
EPA
concluded
that
Chlor
 
7
should
not
be
considered
to
have
a
common
mechanism
to
the
other
chloroacetanilides
based
on
the
following
reasons:
 
Except
for
Chlor
 
7
all
other
members
of
this
case
study
have
a
potential
to
generate
a
quinone
imine.
The
quinone
imine
intermediate,
is
capable
of
reacting
with
macromolecules.
 
Chlor
 
7
has
not
produced
nasal
nor
thyroid
tumors
in
rats,
thus
does
not
support
inclusion
in
the
group
for
a
common
mechanism
for
these
tumor
types.
For
liver
tumors,
Chlor
 
1,
Chlor
 
7,
Chlo
 
r5,
and
Chlor
 
6,
can
be
potentially
grouped
for
a
common
mechanism,
but
EPA
determined
that
there
is
no
knowledge
of
a
common
mechanism
of
toxicity
or
of
a
common
toxic
species
responsible
for
the
effect.
Therefore,
EPA
concluded
that
because
a
mechanism
can
not
be
postulated,
it
believes
that
sufficient
evidence
is
not
available
to
support
a
common
mechanism
for
this
tumor
type
with
these
materials.
Therefore,
BASF
agrees
with
the
position
put
forward
by
the
Agency
and
confirmed
by
the
SAP
that
a
common
mechanism
is
inappropriate
for
dimethenamid
(
Chlor
 
7)
and
the
other
chloroacetanilides
mentioned
in
section
D.
BASF
has
considered
only
the
potential
risks
of
dimethenamid
in
its
exposure
assessment.

E.
Safety
Determination
1.
U.
S.
population.
Using
the
exposure
assumptions
described
in
section
C.,
based
on
the
completeness
and
the
reliability
of
the
toxicity
data,
BASF
has
estimated
that
aggregate
exposure
to
dimethenamid
will
utilize
<
1%
of
the
RfD
(
0.05
mg/
kg/
day)
for
the
U.
S.
population.
EPA
generally
has
no
concern
for
exposure
below
100%
of
the
RfD.
Therefore,
based
on
the
completeness
and
reliability
of
the
toxicity
data,
and
the
exposure
assessment
discussed
in
sections
B.
and
C.,
BASF
concludes
that
there
is
a
reasonable
certainty
that
no
harm
will
result
from
aggregate
exposure
to
residues
of
dimethenamid
including
all
anticipated
dietary
exposure
and
all
other
non­
occupational
exposures.
2.
Infants
and
children.
BASF
cites
results
of
developmental
toxicity
studies
reported
in
section
B.
3.
including:
 
Observed
developmental
toxicity
effects
in
rats
are
not
indicative
of
teratogenic
effect.
 
The
results
of
developmental
study
in
rabbits
also
demonstrated
that
dimethenamid
is
not
a
teratogenic
compound
and
has
a
development
toxicity
NOAEL
of
75
mg/
kg/
day
and
a
maternal
toxicity
of
37.5
mg/
kg/
day.
BASF
believes
that
these
test
results
demonstrate
that
the
rat
and
rabbit
are
similarly
sensitive
to
dimethenamid.
Additionally,
the
NOAEL
of
5
mg/
kg/
day
from
the
chronic
rat
study
used
to
set
the
RfD
is
7.5X
and
5X
lower
than
the
maternal
NOAELs
established
in
the
rabbit
and
rat
teratology
studies,
respectively.
The
developmental
effects
observed
in
either
the
rat
or
rabbit
occurred
only
at
maternally
toxic
doses.
Therefore,
BASF
concludes
that
no
additional
safety
factor
is
needed
for
children.
F.
International
Tolerances
A
maximum
residue
level
has
not
been
established
under
Codex
Alimentarius
Commission
for
dimethenamid
for
any
of
the
proposed
uses.
