in
response
to
solicitations
for
the
43
vanadium
compounds
listed
in
the
ITC's
51st
Report
(
Ref.

the
ITC
reviewed
the
PAIR
reports
submitted
in
response
to
the
June

listed
in
the
ITC's
51st
Report.
The
ITC
is
continuing
to
analyze
the
data
in
those
reports
as
well
as
data
submitted
voluntarily.
For
the
43
vanadium
compounds
listed
in
the
ITC's
51st
Report
(
Ref.
6),
the
ITC
is
still
soliciting
voluntary
submissions
of:
1.
Recent
non­
CBI
estimates
of
annual
production
or
importation
volume
data
and
trends,
and
use
information,
including
percentages
of
production
or
importation
that
are
associated
with
different
uses.
2.
Estimates
of
the
number
of
humans
and
concentrations
of
vanadium
compounds
to
which
humans
may
be
exposed
during
manufacturing
or
processing.
3.
Health
effects
data
including
pharmacokinetics,
genotoxicity,
subchronic
toxicity,
reproductive
and
developmental
toxicity,
and
any
human
data
from
occupationally
exposed
workers.
The
ITC
is
soliciting
this
information
in
order
to
adequately
assess
the
extent
and
degree
of
exposure
and
potential
hazard
associated
with
the
various
forms
of
vanadium.
In
addition,
the
ITC
is
soliciting
voluntary
information
submissions
for
the
3
pyridinamines
and
20
tungsten
compounds
being
added
to
the
Priority
Testing
List
to
meet
U.
S.
Government
data
needs.

information
being
solicited
is

Revisions
to
the
TSCA
Section
4(
e)
Priority
Testing
List
A.
Chemicals
Added
to
the
Priority
Testing
List
1.
Pyridinamines
 
a.
Recommendation.
Pyridinamines
are
being
added
to
the
Priority
Testing
List
to
obtain
importation,
production,
use,
exposure,
and
health
effects
information
to
meet
U.
S.
Government
data
needs.
Three
pyridinamines
are
being
recommended:
2­
Pyridinamine
(
CAS
No.
504
 
29
 
0),
3­
pyridinamine
(
CAS
No.
462
 
08
 
8)
and
4­
pyridinamine
(
CAS
No.
504
 
24
 
5).
b.
Rationale
for
recommendation.
Pyridinamines
are
readily
absorbed
through
the
skin
and
the
gastrointestinal
tract
and
widely
distributed
in
the
body,
including
the
brain.
They
are
not
metabolized
and
are
completely
excreted
through
the
kidneys.
Studies
in
animals
and
humans
have
shown
that
pyridinamines
are
acutely
toxic
compounds.
Part
of
this
toxic
response
may
be
due
to
their
ability
to
block
K+
channels
causing,
among
other
effects,
convulsions.
The
chronic
toxicity
of
these
compounds
has
not
received
adequate
evaluation.
To
determine
a
priority
for
testing
members
of
the
pyridinamine
class
of
compounds,
additional
information
is
needed
to
characterize
human
exposure
potential.
c.
Information
needs.
For
each
individual
pyridinamine:
Recent
data
or
estimates
of
annual
production
and
importation
volume
and
trends;
information
on
specific
uses,
including
percentages
of
production
or
importation
volume
associated
with
each
of
these
uses;
estimates
of
the
number
of
persons
potentially
exposed
to
each
pyridinamine
during
its
manufacture
and
use
and
health
effects,
including
chronic
toxicity
data.
d.
Supporting
information.
Pyridinamines
are
chemicals
in
commerce.
The
annual
production
volume
of
2­
pyridinamine
exceeded
1
million
pounds
in
1998;
it
is
used
in
hair
colorants
and
as
an
intermediate
in
the
manufacture
of
pharmaceuticals.
3­
Pyridinamine
is
an
intermediate
in
the
production
of
agrochemicals
and
pharmaceuticals;
it
may
have
end­
uses.
In
addition
to
its
use
as
a
chemical
intermediate,
4­
pyridinamine
is
the
active
ingredient
in
the
registered
pesticide
Avitrol
 
and
has
been
evaluated
as
an
experimental
drug
to
treat
several
neurological
syndromes.
Under
the
Food
and
Drug
Administration
(
FDA)
Modernization
Act
of
1997
(
http://
www.
fda.
gov/
opacom/
7modact.
html),
4­
pyridinamine
was
nominated
for
inclusion
on
the
list
of
bulk
substances
for
use
in
pharmacy
compounding
but
was
not
included
by
the
FDA
on
the
initial
list.
Human
exposure
data
are
limited
for
pyridinamines.
A
survey
conducted
between
1981
and
1983
by
the
National
Institute
for
Occupational
Safety
and
Health
estimated
that
4,618
workers
in
452
facilities
representing
3
industries
were
potentially
exposed
to
4­
pyridinamine.
2.
Tungsten
compounds
 
a.
Recommendation.
Twenty
tungsten
compounds
are
being
added
to
the
Priority
Testing
List
to
obtain
importation,
production,
use,
exposure,
and
health
effects
information
to
meet
U.
S.
Government
data
needs
(
Table
2).
The
ITC
believes
the
list
of
tungsten
compounds
in
Table
2
includes
those
most
likely
to
be
in
current
use.

Rationale
for
recommendation.
Tungsten
was
recently
nominated
for
toxicology
and
carcinogenicity
studies
to
the
National
Toxicology
Program
by
the
Centers
for
Disease
Control
and
Prevention's
National
Center
for
Environmental
Health
(
http://
ntpserver
niehs.
nih.
gov/
NomPage/
2003Noms.
html).
The
nomination
was
based
on
recent
data
showing
elevated
tungsten
body
burdens
in
residents
of
Fallon,
NV,
and
the
limited
data
available
to
assess
the
potential
long­
term
adverse
health
effects
of
tungsten
exposure
(
http://
www.
cdc.
gov/
nceh/
clusters/
Fallon).
The
source
and
pathways
of
exposure,
and
the
form
of
tungsten
to
which
Fallon,
NV,
residents
are
exposed
is
presently
poorly
understood.
The
Agency
for
Toxic
Substances
and
Disease
Registry
(
ATSDR)
has
completed
community
exposure
and
health
investigations
in
Churchill
County,
NV
(
http://
www.
atsdr.
cdc.
gov/
HAC/
PHA/
region_
9.
html#
nevada)
and
is
developing
a
toxicological
profile
for
tungsten
(
http://
www.
atsdr.
cdc.
gov/
toxprofiles/
tp186.
html).
Tungsten
and
tungsten
compounds
have
numerous
important
industrial
uses.
Other
than
workplace
exposure
limits,
there
are
few
regulatory
controls
on
the
use,
emission,
and
disposal
of
tungsten
compounds
and
few
data
on
which
to
assess
the
ecological
effects
and
human
health
impacts
resulting
from
environmental
and
general
population
exposures.
Further
information
is
needed
to
more
fully
evaluate
human
and
environmental
exposures
and
health
effects.
c.
Information
needs.
To
meet
U.
S.
Government
data
needs,
the
ITC
needs:
1.
Recent
non­
CBI
estimates
of
annual
production
or
importation
volume
data
and
trends,
and
chemical­
specific
use
information,
including
percentages
of
production
or
importation
that
are
associated
with
different
uses.
2.
Environmental
release
and
monitoring
information,
including
occurrence
and
concentrations
in
environmental
media.
3.
Fate
and
transport
data.
4.
Ecological
effects
data,
especially
for
aquatic
and
sediment
organisms,
if
there
is
evidence
that
tungsten
compounds
are
mobilized
and
transported
to
groundwater,
surface
water,
and
sediments.
5.
Estimates
of
the
number
of
exposed
humans
and
concentrations
of
tungsten
compounds
to
which
humans
may
be
exposed
in
each
relevant
manufacturing,
processing,
or
other
occupational
scenario.
6.
Case
studies
from
occupationally
exposed
workers
and
pharmacokinetics,
dermal,
inhalation,
and
oral
acute
toxicity,
subchronic
toxicity,
chronic
toxicity,
genotoxicity,
carcinogenicity,
neurotoxicity,
reproductive
and
developmental
toxicity,
and
epidemiology
studies.
The
ITC
is
soliciting
this
information
in
order
to
adequately
assess
the
extent
and
degree
of
exposure
and
potential
hazard
associated
with
the
various
forms
of
tungsten
and
to
determine
if
additional
test
data
are
needed.
d.
Supporting
information.
Tungsten
compounds
are
naturally
released
to
the
atmosphere
by
windblown
dusts.
Tungsten
compounds
can
be
released
to
surface
waters
from
sources
of
human
origin
(
e.
g.,
water
effluents
from
tungsten
mining).
Deposition
of
tungsten
aerosols
or
dusts
from
both
natural
and
anthropogenic
sources
is
also
a
source
of
tungsten
in
surface
waters.
Individuals
who
work
in
manufacturing,
fabricating,
and
reclaiming
industries,
especially
individuals
using
hard­
metal
materials
or
tungsten
carbide
machining
tools,
may
be
exposed
to
higher
levels
of
tungsten
compounds
than
the
general
population.
Occupational
exposure
is
primarily
via
inhalation
of
dust
particles
of
elemental
(
metallic)
tungsten
and/
or
its
compounds.
Pulmonary
fibrosis,
memory
and
sensory
deficits,
and
increased
mortality
due
to
lung
cancer
have
been
associated
with
occupational
exposure
to
dusts
generated
in
the
hard­
metal
industry.
Historically,
the
respiratory
and
neurological
effects
observed
in
hard­
metal
workers
have
been
attributed
to
cobalt,
not
tungsten.
However,
based
on
the
presence
of
tungsten
oxide
fibers
in
air
samples
taken
at
some
hard­
metal
facilities
and
demonstrations
that
tungsten
oxide
fibers
are
capable
of
generating
hydroxyl
radicals
in
human
lung
cells
in
vitro,
it
has
been
suggested
that
tungsten
oxide
fibers
may
contribute
to
the
development
of
pulmonary
fibrosis
in
hard­
metal
workers.
Limited
reports
associate
tungsten
exposure
with
reproductive
and
developmental
effects
such
as
decreased
sperm
motility,
increased
embryotoxicity,
and
delayed
fetal
skeletal
ossification
in
animals.
Tungsten
has
been
observed
to
cross
the
placental
barrier
and
enter
the
fetus.
Dermal
or
ocular
exposure
to
tungsten
may
result
in
localized
irritation.
