INDUSTRY AND FLUORIDATION
INDUSTRY WELCOMED fluoridation with open arms. Chemical Week,
a publication for the chemical industry, vividly portrayed this
fact in 1951 with an enthusiastic news account:
All over the country, slide rules are getting warm as waterworks
engineers figure the cost of adding fluoride to their municipal
supplies. They are riding a trend urged upon them by the US Public
Health Service, the American Dental Association, the State Dental
Health Directors, various state and local health bodies, and vocal
women's clubs from coast to coast. ... it adds up to a nice piece
of business on all sides and many firms are cheering the USPHS
and similar groups as they plump for increasing adoption of fluoridation.
(1)
The beneficiaries named in this article were chemical companies
and equipment firms: General Chemical, Harshaw
Chemical Co., Blockson Chemical Co., American Agricultural Chemical
Co., Aluminum Co. of America (ALCOA), Davison Chemical Corp., and
Baugh Chemical Co. Chemical Week obviously failed to discuss
how many other industries in addition to chemical corporations would
eventually gain financially from the unexpected bonanza. Even so,
the desire of corporations to sell their products was not the only
significant motive for industry to "plump" for the new health measure.
THE PROBLEM
In the early 1930s, ALCOA and other manufacturers of aluminum had
a problem so serious that it threatened their very existence. During
the smelting and reduction process, when bauxite (aluminum oxide)
is dissolved and electrolyzed in molten cryolite, hydrogen fluoride
and other volatile fluorides are released into the air, and sodium
fluoride remains in the bath. (2) The latter cannot simply be dumped
on the ground because it seriously pollutes grass and other forage.
Indeed, in 1950 ALCOA's plant in Vancouver, Washington, was fined
for dumping fluorides into the Columbia River, and the airborne
fluorides heavily contaminated the grass and forage, "which resulted
in injury and death to cattle." (3) If it could be established
further that human health also suffered from fluoride pollution,
the consequences to the company in terms of damage suits would have
been immeasurable.
Damage to Animal Life. Many other industries, especially
the manufacturers of steel and phosphate fertilizer, shared this
problem with ALCOA. On August 25, 1961, W. S. Meader and his wife
May, near Pocatello, Idaho, obtained a judgement in the US Court
of Appeals, Ninth Circuit, against Food Machinery and Chemical Corp.
for the sum of $57,295.80 and against J. R. Simplot Co. for $4,246.41.
The factories of these corporations emitted solid and gaseous fluoride
compounds which seriously damaged the Meader trout farm and fish
hatchery. According to the court record, "eggs were worthless" and
did not hatch properly; the fish also exhibited malformations. "During
the week after rains, the Meaders were hauling away about a ton
of dead fish per day." (4) Fluoride levels in water samples
from the Meader hatchery ranged between 0.5 and 4.7 ppm - no different
than the fluoride concentrations in food and drinks consumed today
by humans in many places. Inevitably, the business of the farm began
to deteriorate as "customers were lost."
Damage to fish is not the only source of litigation resulting from
environmental fluoride. Ever since the beginning of the industrial
revolution, wholesale pollution of air and of the countryside with
fluoride fumes and fallout has taken place, and fluoride poisoning
has become an important industrial hazard. Early reports of damage
came from Great Britain and also from Freiburg, Germany, where by
1893, 880,000 marks (about $200,000) had been paid for current injuries
and 644,000 marks for permanent relief. Around the industrial city
of Freiburg in Saxony a disease of cattle, endemic for 20 years,
was identified in 1907 as fluoride poisoning from the smelters.
(5) At about the same time, cattle near copper mines of Anaconda,
Montana, were reported to have developed "copper teeth," which were
remarkably similar to what was later recognized in humans as "Colorado
brown stain" or "mottled teeth" (Fig. 17-1). (6)
In the early 1950s American industry was plagued with a virtual
epidemic of litigation. In 1950, Mr. and Mrs. Julius Lampert had
won their suit against the Reynolds Metals Company's Troutdale aluminum
plant for fluoride burns to their gladiolus crops. (7) In Blount
County, Tennessee, prior to January 1, 1953, ALCOA had hardly made
up the loss of income incurred by 141 farmers and cattle raisers,
(8) when another suit charged that fluoride fumes "damaged farmlands,
injured registered cattle," making them unmarketable, and caused
premature deterioration of teeth, stiffness of joints, knots on
ribs, loss of appetite, and general retardation of growth. (9)
Other suits involved the ALCOA plant at Vancouver, Washington,
which had to pay cattleman William Fraser $60,000 in 1962 and in
the same year, $20,000 to Earl Reeder because of fluoride injury
to their cattle on Sauvies Island. (10) In 1961 Fairview Farms.
Inc., received $300,000 from the Harvey Aluminum Company's reduction
plant in The Dalles, Oregon, because of damage to dairy herds, loss
of forage and of milk supply, as well as depreciation of the lands.
Orchardist W. J. Meyer and his wife Mary Ann also received $485,000
for "willful damage" to cherry, apricot, and peach crops. (11)
The threat to farming by fluoride pollution can be visualized if
we realize that Polk
County, which was Florida's leading cattle producer in 1954
with 120,000 head, had some 30,000 fewer cattle by 1965. Fluoride
emissions from phosphate plants on pastures were building up toxic
levels as high as 1800 ppm in the grass and other forage. The official
maximum allowable concentration for cattle is 40 PPM, (12) but even
this level permits significant damage. (13)
Human Health. When human health was at stake, the spectre
of these damage suits became even more ominous for the corporations.
In the 1955 suit Paul M. Martin and his wife Verla vs. Reynolds
Metals, it was proved for the first time in the United States that
fumes from an aluminum reduction plant had caused illness to humans.
(14) The significance of this litigation is underscored by the fact
that seven other aluminum, metal, and chemical companies joined
Reynolds Metals as "friends of the court" to obtain a reversal of
the judgement against their fellow corporation. Fred Yerke, a Reynolds
attorney, "contended that, if allowed to stand, the verdict would
become a ruling case, making every aluminum and chemical plant liable
to damage claims merely by operating." (15) The verdict did stand:
in June 1958, the U.S. Court of Appeals upheld the decision against
Reynolds by a five to one vote. (16) Finally, in 1968, the company
settled the case by buying the Martin ranch - a solution to the
problem that has been followed by other corporations.
Another suit involving human health threatened the Rocky
Mountain phosphate plant in Garrison, Montana, when residents
complained constantly of "strep" throats, burning eyes, and asthmatic
symptoms which they associated with fumes emanating from the plant.
Classes of the Garrison school were interrupted 35 times during
the first year of the plant's operation (1963-1964) because of fluoride
fumes. That fluoride was the chief culprit became evident when ranchers
observed: their cows suffered from mottled teeth (Fig. 17-1) and
legs so stiff and painful that they had to graze on their knees
(Fig. 17-2). Samples of vegetation near the stack fallout showed
fluoride concentrations several thousand times the usual levels.
(17) In spite of the installation of pollution control equipment,
the plant had to be shut down repeatedly. Finally, the factory discontinued
operation altogether for reasons unrelated to the pollution problem.
In another part of the country, a jury decided on March 13, 1972,
in favor of P. G. and P. N. Barci, father and son, in the suit of
Barci vs. Intalco Aluminum Company of Ferndale, Washington, because
of damage to cattle, trees, and to human health. A lung specialist
from Spokane testified that P. G. Barci suffered from pulmonary
fibrosis, a permanent lung disease which had completely disabled
him. (18) About two years later, the same aluminum company lost
a $130,500 fluoride emission suit to Ray and Helen Freeman, who
resided a mile away from the plant on Lake Terrell. (19)
THE SOLUTION
These are but a few of the numerous law suits highlighting the
magnitude of environmental damage by fluoride. Ironically, the expenditures
I have discussed are small compared to the cost of installing effective
air-cleaning equipment. For instance, by 1957 the United States
Steel Corporation's Columbia-Geneva Division's plant in Provo, Utah,
had spent $9 million to install electrostatic precipitators and
other anti-pollution devices. The same company had previously been
faced with nearly 900 damage claims totaling approximately $4.5
million. (20) Unfortunately, even high-priced air-cleaning equipment
does not solve the problem, since fluoride scrubbed from chimneys
does not disappear; it has to be washed onto the land or into rivers
and lakes and eventually creates further difficulties.
Dismayed by the prospect of continuous litigation and fearful of
recognition of widespread damage to human health, corporations initiated
extensive research programs to convince communities and the courts
that small amounts of fluorine are not harmful to man. They collaborated
with scientists at leading universities and at industrial research
laboratories.
One of these temples of learning is the Mellon Institute in Pittsburgh,
Pa., founded by Andrew W. and Richard B. Mellon, the former owners
of the Aluminum Company of America. LIFE magazine of May 9, 1938,
described the Mellon Institute as an "Intellectual holding company
and a laboratory for applied science open to the US businessman"
where every possible resource and piece of equipment is available
to industry. Such varied subjects as shaving, cigarette technology,
or insecticides could be studied to improve products or to find
new uses for them. LIFE added: "When a manufacturer is in trouble,
for example, he finds the market for his goods is shrinking, he
goes to the Institute. For $6,000 or more he gets a fellowship entitling
him to employ a scientist for a year and use laboratory facilities.
When the research is satisfactorily completed, all discoveries are
turned over to the manufacturer exclusively." (21) Thus, findings
incriminating to the corporations need not be published or presented
to the medical and veterinary professions.
Whereas the Mellon Institute was the most logical place to seek
aid in their precarious plight, corporations also sought help from
other institutions of higher learning, especially the Universities
of Tennessee, Cincinnati, and Wisconsin, all of which received large
research grants to create a favorable climate of opinion for fluoride.
Between 1940 and 1960, a flood of scientific reports issued from
these institutions, which acknowledged the receipt of financial
support from nine corporations, several of whom had been dumping
fluoride into the environment. (22)
One of the scientists engaged in research at the Mellon Institute,
Gerald J. Cox, a biochemist, was to play a major role in promoting
fluoridation. (23) Some of his research had suggested to him that
fluoride "may be specifically required for tooth formation." (24)
He therefore recommended that it be added to water supplies as a
means of reducing tooth decay. (25) On September 29, 1939, Cox told
the Western Pennsylvania Section of the American Water Works Association
meeting at Johnstown that "the present trend toward complete removal
of fluorine from water and food may need some reversal." Cox's term
"reversal" referred to the fact that water works engineers had been
recommending 0. 1 PPM as the maximum level of fluoride in drinking
water because they felt that at least a tenfold margin of safety
should be maintained (Table 17-1 ). (26)

At that time even the official
USPHS regulations stated: "The presence of . . . fluoride in excess
of 1 p.p.m...shall constitute ground for rejection of the water
supply." (27) Because fluoride had been universally recognized
as a toxic agent until then, Cox realized that water works officials
might be held liable for poisoning people drinking fluoridated water.
He therefore cautioned his audience: "Fluorides are among the most
toxic of substances. Mottled enamel results from as little as 0.0001
percent of fluorine in drinking water [1 PPM] . The results on adults
of drinking water containing sufficient fluoride to prevent dental
caries in children must be determined." (25) Cox undeniably sensed
The Great Dilemma right at the start.
Cox's theory that fluoridated water could protect teeth against
decay was based on his own experiments and on evidence provided
in 1938 by W. D. Armstrong, professor of biochemistry at the University
of Minnesota, and a consultant for the Dental Division of the PHS.
In collaboration with P. J. Brekhus, Armstrong had reported more
fluoride in enamel of healthy than in decayed teeth. (28) Twenty-five
years later, however, his own reinvestigation convinced him that
he had misinterpreted his early data, and he realized that the differences
in the fluoride content between the sound and the carious teeth
in his study were due to differences in the age of the teeth and
did not reflect their susceptibility to decay. (29) Thus the basis
of Cox's main argument for recommending the addition of fluorides
to drinking water was later shown to have been wrong!
In 1943, F. A. Arnold, Jr., of the National Institute of Dental
Research in Bethesda, Maryland, took up Cox's suggestion. He advocated
fluoridation in the Journal of the American Dental Association
on the basis of Cox's experiments, Dean's PHS surveys, and the Armstrong-Brekhus
fluoride analyses of tooth enamel. Arnold stated: "The cumulative
toxic effects on the body from ingestion of fluoride in this concentration
is admitted to be a possibility. However, all things considered,
such a possibility seems rather remote." (30) Even in 1946 he still
maintained in his AAAS report that "such a procedure cannot be recommended
for other than research purposes at the present time" and suggested
a study which "may take 12-15 years before the final answer is clearly
delineated." (31)
In the early 1940s Cox had an excellent opportunity to introduce
his idea to scientists when he became a member of the Food and Nutrition
Board of the National Research Council (23) and prepared for this
illustrious body several pro-fluoridation summaries of the literature
on dental caries. Through this organization, with its close link
between industry and government, he was able to influence many scientists...
Cox lost no time in implementing his project. On September 20,
1939, five years before Newburgh and Grand Rapids experiments were
initiated, and at the very time when he first suggested the fluoridation
idea to the water engineers in Johnstown, he recommended fluoridation
for that city; (25) however, his proposal was rejected. Subsequently
he promoted the measure more successfully before chemical and dental
organizations, parent-teacher associations, and city councils.
Nevertheless, Cox's research at the Mellon Institute and his political
activities fell short of relieving the aluminum industry of its
distressing plight. ALCOA also tackled its fluoride pollution problem
on another front, namely through the Kettering
Laboratory in Cincinnati. This institute was founded in 1930
by gifts of the Ethyl Corporation, General Motors' Frigidaire subsidiary,
and the duPont Company to investigate chemical hazards in American
industrial operations. Like the Mellon Institute, it has made many
valuable scientific contributions. Its 1955 budget of $643,000 was
funded by industry (about 90%) and most of the rest by government
agencies. (33) Dr. Robert A. Kehoe, its first chief, one of the
nation's leading industrial toxicologists, personified the close
link between PHS and industry since he was Medical Director of the
Ethyl Corporation and a consultant of the Division of Occupational
Medicine of the PHS, the Tennessee Valley Authority, and tile Atomic
Energy Commission. He and his staff have also been consulted almost
routinely by editors of medical journals as to the suitability of
articles submitted for publication and have thus given industry
a foothold in influencing the medical literature on fluoride. Kehoe
and his colleagues at Kettering also played a key role in developing
government standards to prevent lead poisoning in industry. These
standards have subsequently been criticized severely because they
were far too lax. (34)
Since 1931 a considerable portion of the Kettering Laboratory's
facilities has been devoted to the study of fluoride, particularly
the refrigerant gas Freon 12. Like the Mellon Institute's findings,
those of the Kettering Laboratory are made available to the professions
and to the public only upon approval of the industrial donor of
the grant. Article 8 of one of the contract agreements between the
Aluminum Company of America and the Laboratory specified that the
University of Cincinnati shall "disseminate for the public good
any information obtained. However, before the issuance of public
reports or scientific publications, the manuscripts thereof will
be submitted to the Donor for criticism and suggestions. Confidential
information obtained from the Donor shall not be published without
permission of said Donor." (35) The corporations were allowed to
interpret the term "confidential information." One can only guess
how much valuable research has been lost to the medical profession
because of these agreements.
During the mid-20th century, the research that issued from the
Kettering Laboratory dominated the medical literature on the toxicology
of fluoride. Among its most useful products in the area of fluoride
research were the abstracts and an annotated bibliography prepared
by Irene R. Campbell covering the literature on fluoride through
1971. (36, 37)
Although written mostly by proponents, many scientific articles
in Campbell's annotated bibliography reveal serious health hazards
of fluoride even in small amounts and at low concentrations. It
is impossible to understand, therefore, how Kehoe could state publicly
in March 1957 that "the question of the public safety of fluoridation
is nonexistent from the viewpoint of medical science." (38)
Kettering Institute scientist E. J. Largent, who subsequently became
consultant for Reynolds Metals Company, has written a book entitled
Fluorosis: The Health Aspects of Fluorine Compounds, which
was expressly designed, as indicated on its jacket, to "aid industry
in law suits arising from fluoride damage." This book has been used
as a reference source by many physicians and health organizations
and strongly supports the use of fluoride in drinking water and
discounts or minimizes its toxicological effects: "in recent years
additional surveys of information have been reported that establish
again and again the complete safety of fluoridating drinking water."
(39)
.....
(from page 311-314)
Interestingly, the corporations that originally sponsored fluoridation
rarely promoted their product publicly. In 1950-1951 ALCOA had explicitly
advertised sodium fluoride "of a uniform high degree of purity"
for addition to water supplies in the Journal of the American Water
Works Association (61). On May 22, 1957, however, ALCOA's Chemical
Sales Manager, H.P. Bonebrake, stated in a letter to C.A. Barden
of Oberlin, Ohio, that his firm was not promoting fluoride for water
fluoridation or selling it "directly to any municipality."
Nevertheless, Hearings on Fluoridation before the Committee on Interstate
and Foreign Commerce, House of Representatives, suggest that ALOCA
was the driving force behind fluoridation:
In 1944 Oscar Ewing was put on the payroll of the Aluminum Company
of America, as attorney, at an annual salary of $750,000. This
fact was established at a Senate hearing and became a part of
the Congressional Record. Since the Aluminum Co. had no big litigation
pending at the time, the question might logically be asked, why
such a large fee? A few months thereafter Mr. Ewing was made Federal
Security Administrator with the announcement that he was taking
a big salary cut in order to serve his country. (62)
It was Ewing, as chief of the PHS, who officially gave the green
light to fluoridation only five years after the initiation of the
10 to 15-year experiments in Grand Rapids, Michigan, and Newburgh,
New York. At that time the permanent teeth of children born under
fluoridation had not yet erupted, and therefore no reliable scientific
conclusions concerning its benefits could possibly have been reached.
Prior to Ewing's tenure of office in the federal government, Andrew
Mellon, the founder of ALCOA, had been the U.S. Treasurer. The PHS
was then in the Department of the Treasury. One can only speculate
concerning Mr. Mellon's role as protector of his company. Nor can
it be ascertained whether or not such scientists as Knutson, Dean,
Russell, and their colleagues in the Dental Division of the PHS,
were in any way influenced in their desire to please their boss,
Oscar Ewing. This thought is bound to occur to anyone who is familiar
with governmental agencies; it is also driven home clearly by the
Watergate affair. When decisions are made at the top level -be they
right or wrong -it is not easy for government employees to report
"corruption, waste, or regulatory abuse." The consequences: "Too
often they are characterized as troublemakers, then are fired, frozen
out of promotions or subjected to personal harassment for the rest
of their careers.""
Industry's vital role in promoting fluoridation cannot be doubted
nor can the leadership of ALCOA be denied in this affair. In carefully
orchestrated harmony, industry, science, and the PHS collaborated
in a plan that instituted a health procedure touching virtually
everyone in America. Enormous research activity produced a mountain
of evidence-much positive-that fluoridation was the long-sought
answer to our dental health care problems. But what of the serious
problems discovered? Why were they obscured, discounted, or simply
ignored? If we examine the fluoride literature closely to determine
how much of it was supported or generated by industry and/or the
PHS, we shall find the answers to our questions. We shall also understand
some of the reasons why scientists, physicians, and dentists are
generally ignorant of the true consequences of fluoridation.
