To all:
I will have to take back what I said a day or two ago, and
intervene in this dispute about DU. (Caution: this is a long message;
about 2000 words.)
On March 1, James Salsman offered a challenge to Robert Cherry and
John R. Johnson, asking them to join him in calling for some testing or
release of data pertaining to depleted uranium (DU) and its effects. To
support his claims about the toxicity of DU he offered nine refereed
papers, and gave brief real or purported quotes from each one. On March 4,
he wrote again, saying, I note again that in the additional complaints
about my posts, there remains no opposition to my assertions supported by
the peer-reviewed medical and scientific literature.
I have read the germane portions of eight of the nine papers
Salsman offered, and some additional portions of those eight. (The ninth
one was not available to me.) Below, in the order they appeared in
Salsmans challenge e-mail, are listed the nine papers, exactly as he
posted them on RADSAFE. My comments follow each one. Do they constitute
opposition to James Salsmans assertions that, he says, are supported by
the literature?
At the end of all this I have asked four question which I would
like James Salsman to answer on RADSAFE.

P.R. (2005) "Oxidation states of uranium in depleted uranium particles from
Kuwait." Journal of Environmental Radioactivity, 78, 125135:
http://www.bovik.org/du/Salbu-uranyl-detected.pdf Abstract: "Environmental
or health impact assessments for ... DU munitions should ... take into
account the presence of respiratory UO3...."
The full sentence reads: Environmental or health impact
assessments for areas affected by DU munitions should therefore take into
account the presence of respiratory UO2, U3O8, and even UO3 particles,
their corresponding weathering rates and the subsequent mobilisation rate
of U from oxidised DU particles.
This same sentence is also in the Conclusions, and is followed by
this sentence: As the radioactivity of DU is lower than for natural
uranium impact assessments should focus on DU as a heavy metal
contamination problem. (This study is laboratory work.)

survey of 30,000 veterans." Annals of Epidemiology, vol. 11, pp. 504-11:
http://www.annalsofepidemiology.org/article/PIIS1047279701002459/abstract
Abstract: "Both men and women deployed to the Gulf theater reported
significant excesses of birth defects among their liveborn infants. These
excess rates also extended to the subset of 'moderate to severe' birth
defects [males: OR= 1.78 (CI = 1.19-2.66); females: OR = 2.80 (CI =
1.26-6.25)]."
This paper has an untitled heading listing Purpose, Methods,
Results, and the Conclusion of the study. The Both men sentence is in
the Results, and is followed by this sentence: No statistically
significant differences by deployment status were found among men or women
for stillbirths, pre-term deliveries or infant mortality.
The Conclusion states: The risk of veterans reporting birth
defects among their children was significantly associated with veterans
military service in the Gulf War. This observation needs to be confirmed by
a review of medical records to rule out possible reporting bias. (The
authors describe their study as a health survey.)

"there was a statistically significant increase in the frequency of
dicentric chromosomes (dic) and centric ring chromosomes (cR) in the
veterans. group...."
The quote is correct.
This is a study of 16 British war veterans (Gulf War, Balkans, or
both) who may have been exposed to DU. At the end of their study, the
authors write, Due to the small size and heterogeneity of the study group
our findings should be interpreted with due caution. They continue,
However, the results raise some concern with respect to potential
biological hazards from DU exposure. They go on to recommend further and
larger studies.

of uranium and depleted uranium exposure on reproduction and fetal
development," Toxicology and Industrial Health, vol. 17, pp. 180-91:
http://www.bovik.org/du/reproduction-review-2001.pdf Summary contains: "A
number of studies have shown that natural uranium is a reproductive
toxicant...."
Before the Summary and ongoing research says this, it says, At
this time, the multigenerational effects of DU exposure on rodent
reproduction and development are not known. Studies have shown DU to be
potentially genotoxic and possibly carcinogenic. Then we have Salsmans
quote, which has been truncated: A number of studies have shown that
natural uranium is a reproductive toxicant in rodents and may be toxic and
teratogenic to the developing rodent fetus. The authors endorse more
rodent studies, and the last sentence of the paper says, Alternatively,
exposure to DU alloy may have no adverse impact on rodent reproductive
success or fetal development.
This paper has an untitled heading noting some DU studies on
rats. It then says, There is [sic] limited available data for
reproductive and teratological deficits from exposure to uranium per se,
typically from oral respiratory, or dermal exposure routes. Alternatively,
there is [sic] no data available on the reproductive effects of DU
embedded. The paper reviews published studies of reproductive toxicity
in humans and animals from uranium or DU exposure, and discusses ongoing
animal research to evaluate reproductive effects in male and female rats
embedded with DU fragments, and possible consequences in subsequent
generations. (Note that this is a review paper.)

uranium aerosols: A review from an epidemiological perspective,"
Environmental Health, vol. 4, pp. 17:
http://www.ehjournal.net/content/4/1/17 "Conclusion: In aggregate the human
epidemiological evidence is consistent with increased risk of birth defects
in offspring of persons exposed to DU."
Salsman quotes the Abstracts Conclusions correctly, and the
Abstracts Results say, Animal studies firmly support the possibility that
DU is a teratogen.
For what its worth, in the Acknowledgements, the authors
write: Sunny Miller, executive director of Traprock Peace Center of
Deerfield, MA hosted a presentation by Damacio Lopez (director of IDUST,
International Depleted Uranium Study Team) which Rita Hindin attended and
that eventually led to the writing of this paper. Our appreciation. Thanks
to Len Dietz, Dan Bishop (of IDUST) and Tom Fasy (Mt. Sinai Medical Center,
NYC) for their assistance early on explicating DU toxicology, and to the
Uranium Weapons Study Team (of Traprock Peace Center) for thoughtful
conversations and support to explore leads and deepen understanding of
DU. (New Mexico readers may recognize the name Damacio Lopez. DU is an
important part of his life, and as recently as Jan. 20 he had a letter
published in the Daily Lobo, the University of New Mexico campus
newspaper, calling for yet another study of DU residues around Socorro, NM,
where some DU testing was done in the mid-1980s.) (This is a review paper.)

natural and depleted uranium: a review," Reproductive Toxicology, vol. 15,
pp. 603-9. Abstract: "Decreased fertility, embryo/fetal toxicity including
teratogenicity, and reduced growth of the offspring have been observed
following uranium exposure at different gestation periods."
(No comments. Reproductive Toxicology is not at the local
university library and I could not find it on line.)

uranium," Croatian Medical Journal, vol. 40, pp. 49-66:
http://www.bovik.org/du/asaf_99.htm Abstract: "well documented evidence of
reproductive and developmental toxicity...."
This quoted snippet appears in some untitled introductory
material. The full sentence reads, Radiation toxicity of uranium isotopes
has been recognized since the beginning of the nuclear era, with well
documented evidence of reproductive and developmental toxicity, as well as
mutagenic and carcinogenic consequences of uranium internal
contamination. This sentence is preceded by some general comments about
the purpose of Durakovics paper, and about the chemical toxicity of
uranium. Durakovic had said nothing about DU before writing the sentence
from which Salsman quoted a mere eight words. To be specific, Durakovic
was making a general comment about the radiation toxicity of uranium. He
is not talking about DU in particular. (This is a review paper.)

results of Gulf War I veterans exposed to depleted uranium," International
Archives of Occupational and Environmental Health, vol. 79, pp. 11-21.
Abstract: "genotoxicity measures continue to show subtle, mixed results...."
This paper appears to have been published in 2005, not in
2006. It was accepted in April, 2005, and is a study of veterans of the
first Gulf War who were in their twelfth year of DU exposure.
The full sentence about genotoxicity measures from the
Abstracts Results reads, Markers of early changes in renal glomerular and
tubular function were not statistically different between groups; however,
genotoxicity measures continue to show subtle, mixed results. Before the
Markers sentence, the authors wrote, No clinically significant uranium
related health effects were observed in blood count, blood chemistries
including renal markers, neuropsychological measures, and semen quality or
genotoxicity measures. (This sentence was followed by the Abstracts
Conclusions.)
In their studys Conclusions, the authors write, The subtle but
biologically plausible findings in this chronically exposed, sentinel
cohort continue to reassure on the one hand, but recommend ongoing
surveillance on the other. (This study was a clinical assessment.)

http://www.bovik.org/du/Miller-DNA-damage.pdf Abstract: "chemical
generation of hydroxyl radicals by depleted uranium in vitro exceeds
radiolytic generation by one million-fold...."
There is no sentence in the Abstract that is in any way similar to
the one Salsman quotes, nor is there any sentence in the paper that is
similar to it. Salsmans quote appears to be a patchwork quilt of two or
three sentences from the Abstract.
This study was published in 2002 (accepted, Feb. 2002), and is a laboratory
study on the effects of DU. In their introduction, the authors state that
because of its low specific activity DU is not believed to be a
significant radiation hazard.
END OF COMMENTS
On March 4, James Salsman also wrote:
What, then, is the proper tact [sic] to take, when the peer-reviewed
literature is increasingly clear that dozens of those who were supposed to
have been responsible have in fact been criminally negligent, resulting in
not only harm of the reproductive health of our armed forces and their
civilian families, but the resulting
effect on enlistment rates and thus national security?
This is not a job for polemic couched in any kind of
courtesy. This is a time for action. Those responsible must be held
responsible.
My Questions:
Mr. Salsman: How many of the quotes you offered did you read from
the primary source material? Or, did you collect these quotes from one or
more anti-DU sources and merely reproduce them here?
How do any of these papers show criminal negligence? (I believe
that is a legal term, not an epidemiological term.) It seems likely that
the allegation of harm [to] reproductive health is still a matter of
debate, along with most or all of the other allegations of harm.
Can it be shown that enlistment rates have fallen as a result of
DU exposure? If any studies of this have been published, please give
citations to the primary source material.
This is not a question, but as far as polemics are concerned, I
believe you were the one who made an accusation about a person (or persons)
un-named being cowardly. (You wrote, What does it say about their
regard for the men and women serving in the United States armed forces that
these so-called professionals and their colleagues have not already been
asking these questions? Are they so cowardly that they feel it more
important to depend on a poison with as-yet-unknown long-term effects than
to take personal responsibility for their actions?)
