Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride/kg body weight). [ 2 ] [ 3 ] [ 4 ] Ingestion of fluoride can produce gastrointestinal discomfort at doses at least 15 to 20 times lower (0.2–0.3 mg/kg or 10 to 15 ...
In 2011, the U.S. Department of Health and Human Services (HHS) and the U.S. Environmental Protection Agency (EPA) lowered the recommended level of fluoride to 0.7 mg/L. [51] In 2015, the U.S. Food and Drug Administration (FDA), based on the recommendation of the U.S. Public Health Service (PHS) for fluoridation of community water systems ...
Ligaments and cartilage can become ossified. [2] Most patients with skeletal fluorosis show side effects from the high fluoride dose such as ruptures of the stomach lining and nausea. [3] Fluoride can also damage the parathyroid glands, leading to hyperparathyroidism, the uncontrolled secretion of parathyroid hormones. These hormones regulate ...
If you drink water that's not from a well, you're getting at least some level of fluoride in your tap water. In fact, 75% of fluoride intake comes from drinking water with added fluoride and from ...
Water fluoridation is not mandatory, and while there is a recommended fluoride concentration in drinking water (0.7 milligrams per liter) from the CDC, that level is not an enforceable standard.
The U.S. Public Health Service recommends a fluoride concentration of 0.7 mg/L of drinking water. NIH’s Taylor said there was not enough data to determine whether that level has any impact on ...
The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay. By ...
That doesn't mean the water is fluoride-free: According to the Los Angeles Department of Water and Power, the city's groundwater contains fluoride at concentrations ranging from 0.1 to 0.3 mg/L ...
