Abstract

Case reports are presented of 8 patients with end stage renal disease who while undergoing dialysis received IV, excessive amounts of fluoride due to an unreported spill of hydrofluosilicic acid into the public water supply caused by cross connections in a treatment plant. Water used to mix dialysis solutions in this unit was treated only by a softening device; no reverse osmosis or deionization had occurred. The afebrile illness, predominantly characterized by hypotension, nausea, substernal pain, diarrhea, itching, and vomiting, developed after one to 2 hr of dialysis. One patient upon autopsy was found to have high fluoride levels in lung tissue (5.6 ppm), kidney (7.0 ppm), brain (0.9 ppm) and blood (4.9 ppm). When a chemical accident does occur, public health officials should be immediately informed so that dialysis units and End Stage Renal Disease Networks in particular can be promptly notified. Finally, it is recommended that water purification techniques such as reverse osmosis and deionization be used to ensure high quality dialysate.

    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

  • Fluorosis by the Ministry of Health & Family Welfare, National Health, India.

    Introduction Fluorosis is a crippling disease resulted from deposition of fluorides in the hard and soft tissues of body. It is a public health problem caused by excess intake of fluoride through drinking water/food products/industrial pollutants over a long period. Ingestion of excess fluoride, most commonly in drinking-water affects the teeth

  • Oxidative stress parameters in rats exposed to fluoride and caffeine

    In our experiment, the 1-month effects of caffeine (Caff) and fluoride (F) administered separately and together on nitric oxide and total antioxidant status in serum, brain, liver and kidney of rats were investigated. Also, the influence of caffeine on fluoride excretion with urine was studied. Thirty adult male Wistar rats

    Rats were given Na18F as a radiotracer for F- at varying chemical dose rates by continuous i.v. infusion for 3 h. Blood fluoride was assessed 6-7 times over the infusion period, at the end of which the animals were sacrificed for determination of tissue fluoride distribution. At sublethal dosages, the

    The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts

    The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.
