Background
The
Environmental
Fate
and
Effects
Division
(
EFED)
has
revised
the
Tier
II
surface
water
values
for
the
drinking
water
assessment
and
the
ecological
exposure
assessment
of
pentachloronitrobenzene
(
PCNB).
Also
revised
were
the
terrestrial
exposure
values
for
use
in
the
ecological
exposure
assessment.
Exposure
values
were
revised
using
the
lower
application
rates
proposed
by
the
registrants
for
cabbage,
peanuts
and
cotton.
Also
included
in
this
memo
for
use
during
Phase
Six
of
re­
registration,
i.
e.,
risk
mitigation,
are
terrestrial
and
aquatic
risk
quotients
(
RQs)
that
reflect
the
revised
estimated
environmental
concentrations
(
EECs)
associated
with
the
proposed
reductions
in
applicaton
rates.

Revised
maximum
annual
application
rates
are:
cabbage
 
22.5
lb
ai/
A/
yr
(
down
from
30
lb
ai/
A/
yr);
peanuts
 
1
lb
ai/
A/
yr
(
down
from
10
lb
ai/
A/
yr);
and
cotton
 
1.5
lb
ai/
A/
yr
(
down
from
2
lb
ai/
A/
yr).
For
each
of
these
uses,
all
modeling
(
aquatic
and
terrestrial)
is
done
assuming
that
the
maximum
application
rates
are
given
on
an
annual
basis
and
that
the
maximum
annual
rate
is
equivalent
to
the
maximum
single
application
rate
(
so
that
only
single
applications
occur
for
each
use).
It
is
important
to
note
that
if
the
revised
labels
(
not
available
to
EFED
at
the
time
of
this
review)
state
that
the
rates
are
per
season,
it
may
be
necessary
to
further
revise
the
estimated
drinking
water
concentrations
(
EDWCs)
and
EECs
reported
for
cabbage,
as
cole
crops
may
be
planted
more
than
once
per
year
in
some
regions
of
the
U.
S.
It
is
also
assumed
that
the
maximum
application
rate
given
for
each
use
(
e.
g.,
for
peanuts)
is
the
maximum
rate
across
all
labels
(
including
Special
Local
Need
labels)
for
any
type
of
soil
application
(
e.
g.,
in­
furrow,
t­
band,
etc.)
to
that
crop.

Revised
Risk
Estimation
for
Terrestrial
Species
As
mentioned
previously,
terrestrial
exposure
is
estimated
using
TREX.
This
model
also
calculates
risk
quotients;
output
from
the
TREX
model
is
contained
in
Appendix
B.
Acute
and
chronic
dietary­
based
risk
quotients
for
birds
based
on
maximum
PCNB
residues
are
presented
in
Table
7a.
Avian
acute
dose­
based
risk
quotients
are
also
presented
using
a
bobwhite
quail
LD50
greater
than
2250
mg/
kg
(
Table
7b).
Since
both
the
dietary­
based
and
dose­
based
risk
quotients
rely
on
avian
toxicity
endpoints
that
exceed
the
highest
concentration
tested,
all
acute
avian
RQ
values
are
less
than
the
calculated
values.
