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 recent years, SCE analysis has […]
Fluoride’s Mutagenicity: In vitro Studies
According to the National Toxicology Program, “the preponderance of evidence” from laboratory “in vitro” studies indicate that fluoride is a mutagenic compound. Many substances which are mutagens, are also carcinogens (i.e. they can cause cancer). As is typical for in vitro studies, the concentrations of fluoride that have generally been tested are far higher (millimolar levels) […]
New Study Fails to Refute Fluoride-Osteosarcoma Link
A paper in the Journal of Dental Research by dentist Chester Douglass and colleagues, “An Assessment of Bone Fluoride and Osteosarcoma,” claims to show no association between fluoride bone levels and osteosarcoma, a form of bone cancer. However, Douglass’ study has serious scientific flaws and is incapable of disproving a previous study which linked water fluoridation to osteosarcoma.
Micronucleus and Sister Chromatid Exchange Frequency in Endemic Fluorosis
The rise of sister chromatid exchange (SCE) and micronucleus (MN) in the peripheral blood lymphocytes of the fluorine-intoxicated patients indicates that fluorine is a mutagenic agent which can cause DNA and chromosomal damage.
Scientist Who Spoke Out on Fluoride Ordered Reinstated to Job
A two-year battle against the federal government ended in victory for a scientist fired from the Environmental Protection Agency after raising health concerns about fluoride. Labor Secretary Robert B. Reich ordered that William L. Marcus be returned to his $ 87,000-a-year job at EPA and be paid back wages, legal costs and a $ 50,000 penalty.
Reich Orders EPA to Reinstate Scientist
In a precedent-setting ruling, U.S. Department of Labor (DOL) Secretary Robert B. Reich has ordered the U.S. Environmental Protection Agency (EPA) to reinstate toxicologist Dr. William L. Marcus.
EPA Ordered to Reinstate Whistleblower
The Environmental Protection Agency has been ordered to reinstate a senior scientist and pay him $ 50,000 for emotional distress after he was fired allegedly for whistleblowing activities. The Administrative Law Judge concluded that EPA’s reason for the firing were “a pretext” and that Marcus really was dismissed “because he publicly questioned and opposed EPA’s fluoride policy.”
Fluoride bioassay study under scrutiny
A recent animal study by the National Toxicology Program that failed to give fluoride a totally clean bill of health is now being questioned as being maybe too lenient on the widely used tooth decay preventative. Also, a government panel appointed to assess the risks and benefits of human exposure to fluoride and to put the NTP study into broader perspective is apparently running into some problems and has delayed its final report.
Weak Link on Fluoride and Cancer Is Backed
A panel of scientific experts today endorsed the findings of a Federal investigation showing that a compound widely used to fluoridate public water supplies may cause bone cancer in male rats.
Rat Study Reignites Dispute On Fluoride
A long-smoldering dispute over the safety of fluoridating public water supplies has flared anew, forcing the nation’s top health officials to reevaluate the risks and benefits of using fluorides to reduce tooth decay. The latest review was triggered by a Congressionally mandated study that recently reported evidence that high doses of fluoride may cause cancer […]
