Abstract
Two independent experiences with animals in captivity revealed a dramatic onset of severe debilitating symptoms when the nonfluoridated water supplies were changed to municipal water fluoridated with fluorosilicic acid, H2SiF6. The first group of animals, chinchillas in a small fur farm operation, quickly more than doubled their water consumption with the change to silicofluoridated water and gradually began to have inferior fur quality, stillbirths, and premature mortality. In the second group of animals, when a similar change in the water occurred, caimans and alligators in a noncommercial private animal collection exhibited swelling and ulceration of eye membranes and later bloated bellies, liver silicosis, spinal deformity, tumors, and shortened life spans. The health of the rat colony in this collection rapidly deteriorated and numerous tumors developed. When hatchling caimans were raised in distilled water, they remained healthy until, because of their size, they were transferred to the silicofluoridated water, after which the above symptoms began to appear. Similarly, when the rats were changed to distilled water, tumor formation ceased, and they became healthy with greatly extended life spans.

Fluoride in Drinking Water: A Scientific Review of EPA’s Standards.
Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

The influence of fluoride on the content of testosterone and cholesterol in rat
Fifty four Wistar male rats were randomly divided into three groups, drinking water containing 0.6 mg/L (control group), 100 mg/L, and 200 mg/L sodium fluoride, respectively. Rats were killed at the second, fourth and sixth weeks after experiment initiation, respectively. The levels of serum testosterone, testis cholesterol, and hepatic tissue

Excess dietary fluoride affects laying performance, egg quality, tissue retention, serum biochemical indices, and reproductive hormones of laying hens.
The present study aimed to evaluate the effects of excess dietary fluoride (F) on laying performance, egg quality, tissue retention, serum biochemical indices, and serum reproductive hormones of laying hens. A total of 384 Hy-Line Gray hens, 37 wk old, were treated with sodium fluoride added to a corn-soybean meal

Evaluation of the toxicity of fluorine in Antarctic krill on soft tissues of Wistar rats
Antarctic krill are a potential food source for humans and animals, but krill are known to contain high levels of fluorine (F). In this study, we investigated the toxicity of F in Antarctic krill using Wistar rats. There were three experimental groups: The control group were fed a basal diet,

Fluoride's Mutagenicity: In vivo Studies
Consistent with dozens of in vitro studies, a number of in vivo studies, in both humans and animals, have found evidence of fluoride-induced genetic damage. In particular, research on humans exposed to high levels of fluoride have found increased levels of "sister chromatid exchange" (SCE). As noted in one study: "In

Fluoride & Liver Cancers in NTP Bioassay
On October 28, 1988, Battelle Columbus Laboratories submitted its Final Report to the NTP concerning the results of the Mouse study. The principal finding of Battelle's report was that a dose-dependent increase of a rare liver cancer (hepatocholangiocarcinoma) had occurred in the fluoride-treated male and female mice.

A Critique of Gelberg's Study on Fluoride/Osteosarcoma in New York
The case-control study by Gelberg, published first as a PhD dissertation and then later in two peer-reviewed journals, may represent the most substantive study on fluoride/osteosarcoma previous to Bassin’s 2001 analysis. In assessing Gelberg’s data, we were at first struck by the existence of several notable errors in both the thesis and papers. While these errors do raise questions about the study, our primary concern with Gelberg’s work relates to the methods she used to analyze her data.
