  • 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

  • Suppression of pulmonary antibacterial defenses mechanisms and lung damage in mice exposed to fluoride aerosol

    In endemic fluorosis areas in China associated with coal burning, indoor airborne fluoride pollution is severe. To determine the effects of fluoride aerosols on pulmonary antibacterial defense mechanisms and lung damage, mice were exposed to various concentrations of fluoride aerosol (2, 5, or 10 mg/m3) or filtered air (control) for

  • [Hydrofluoric acid injury analysis on the health of workers].

    Objective: To analyze the damage caused by hydrofluoric acid to the health of operating workers and to explore health monitoring indicators. Method: Occupational health examinations were carried out on 536 hydrofluoric acid operating workers from the etching process at a certain factory, and 256 persons in the control group. Results: Among the

  • Review of the Bartlett-Cameron survey: a ten year fluoride study.

    Analysis of the data produced the following conclusions: 1.  As was expected, dental fluorosis was significantly greater in Bartlett than in Cameron (all of the participants born and in continuous residence in Bartlett during the tooth formative period exhibited positive evidence of dental fluorosis). 2.  The incidence of cardiovascular disease was higher

  • A longitudinal study of respiratory symptoms in aluminum potroom workers

    The influence of occupational work exposure and host factors on the incidence of dyspnea and wheezing as reported in questionnaires was examined in 1,301 new employees in aluminum electrolytic potrooms. The incidence appeared to decrease after 2 yr of exposure, and the estimated probability of development of symptoms was nearly

  • Fluoride Enhances Toxicity of Beryllium

    Occupational exposure to beryllium is well-documented to put workers' health at risk. The two principal targets of beryllium poisoning are the respiratory system and the skin. Of all beryllium compounds, beryllium fluoride complexes (including beryllium fluoride and beryllium oxyfluoride) appear to be the most toxic. As shown below, studies dating back

  • Respiratory Risks from Occupational Fluoride Exposure

    Starting in the 1930s, scientists have observed that workers exposed to airborne fluorides suffer from an elevated rate of respiratory disorders. For over 50 years, however, US government and industry scientists made repeated assurances that the allowable level of fluoride dusts and gases in industrial workplaces would not cause any

  • Fluoride & Arteriosclerosis

    Healthy arteries are flexible and elastic, allowing efficient transfer of blood and nutrients from the heart to the rest of the body. Arteriosclerosis refers to a stiffening of the arteries, including loss of elasticity. This is a slow, progressive disease that may begin early in life from damage to the

  • Fluoride & Myocardial Damage

    Structural damage to the heart resulting from fluoride toxicity has been observed in numerous human and animal studies. The general features of this damage include cloudy swelling, vacuolization or vacuolar degeneration, hemorrhages, interstitial edema, fibrous necrosis, dissolution of nuclei, and thickening of the vessel walls in the heart muscle (Basha

  • Is the Ingestion of Fluoride an Immunosuppressive Practice?

    This paper records several observations which suggest that habitual ingestion of small doses of fluoride, even as small as the 1 mg/L contained in fluoridated water, may decrease the function of the immune system.
