Discussion
Chloropicrin
is
a
non­
selective
soil
fumigant
whose
primary
toxic
effect
is
sensory
irritation
in
which
stimulated
free
nerve
endings
mediate
sensations
and
clinical
signs
in
the
nose,
eyes,
throat,
and
upper
respiratory
tract.
Chloropicrin
is
a
unique
soil
fumigant
in
that
it
is
also
used
as
an
indicator
chemical
or
warning
agent
(
2%
or
less
by
weight
in
formulations).
The
Agency
is
developing
an
assessment
to
estimate
inhalation
risk
to
bystanders
and
workers
from
acute
exposures
to
chloropicrin.

Scientific
considerations:

The
Agency's
"
Weight
of
Evidence"
(
WOE)
document
and
Data
Evaluation
Records
(
DER)
for
chloropicrin
describe
the
study
design
of
the
acute
inhalation,
human
toxicity
study.
The
Agency
has
concluded
that
the
human
toxicity
study
is
appropriate
for
developing
a
point
of
departure
for
extrapolation
of
inhalation
risk
to
bystanders
and
workers
exposed
to
chloropicrin.

Please
comment
on
whether
the
study
is
sufficiently
sound,
from
a
scientific
perspective,
to
be
used
to
estimate
a
safe
level
of
inhalation
exposure
to
chloropicrin.

2.
Ethical
considerations:

The
Agency
requests
that
the
Board
provide
comment
on
the
following:

a.
Is
there
clear
and
convincing
evidence
that
the
conduct
of
the
Cain
study
was
fundamentally
unethical?

b.
Is
there
clear
and
convincing
evidence
that
the
conduct
of
the
study
was
significantly
deficient
relative
to
the
ethical
standards
prevailing
at
the
time
the
research
was
conducted?

In
private

research
laboratories,
investigators
themselves
have
sometimes
served
as
research
subjects
when
assessing
chemicals
for
insect
repellent
activity.
What
scientific
and
ethical
issues
would
such
a

raise?
Under
what
conditions,

g.
Please

an
ethical
obligation

Discussion
The
Agricultural
Handlers
Exposure
Task
Force
(
AHETF)
has
submitted
protocols
for
five
pesticide
exposure
studies
that
are
part
of
a
larger
research
program
the
AHETF
is
conducting.
The
premise
of
the
AHETF
research
program
is
that
data
can
be
used
generically
by
various
stakeholders
(
e.
g.,
applicants,
registrants,
EPA,
and
others)
for
calculating
exposures
for
the
occupational
handlers
of
pesticides.
The
scope
of
the
AHETF
research
program
is
very
broad
in
that
it
intends
to
address
exposures
related
to
many
job
functions
in
agriculture
and
also
to
assess
generally
the
impacts
of
various
parameters
on
exposure
(
e.
g.,
How
do
changes
in
the
pounds
of
pesticide
handled
or
acres
treated
affect
exposure
levels?).
The
protocols
submitted
for
HSRB
review
describe
studies
to
measure
exposures
for
five
specific
scenarios
(
i.
e.,
closed
or
open
system
mixing/
loading
,
airblast
applications
to
trellis
and
orchard
crops,
or
pilot
exposures
from
fixed
wing
agricultural
aircraft).

The
Agency
believes
these
studies
improve
EPA's
ability
to
assess
the
risks
of
using
pesticides
because
the
data
will
reflect
current
agricultural
practices,
equipment
and
techniques
and
will
allow
for
more
refined
exposure
estimates.
Further,
the
monitoring
techniques
to
be
used
for
these
studies
also
have
been
standardized
for
use
across
the
AHETF
research
program..
These
more
refined
and
reliable
data
will
allow
the
Agency
to
estimate
better
how
worker
exposure
levels
are
affected
by
changes
in
various
factors
such
as
the
amount
of
active
ingredient
handled,
type
of
application
equipment
used,
application
rate
used,
volumes
handled,
and
personal
protective
equipment
used.

It
should
be
noted,
however,
that
the
use
of
the
data
generated
in
this
study
by
the
U.
S.
EPA
and
other
stakeholders
will
depend
upon
the
nature
of
the
results.
For
example,
the
adequacy
of
the
field
or
laboratory
quality
control
data
may
dictate
that
correction
factors
are
applied
to
adjust
monitored
exposure
levels
to
account
for
losses
from
field
samplers
or
low
performing
analytical
methods.
