Abstract

The increased excretion of fluorides in urine was shown by ion-selective method, in three different groups of workers, inhabitants of Chorzów–the most polluted town in the Upper Silesia. In nearly all workers (90%) of Nitrogen Chemical Plant and Slaughterhouse (groups A and M), the urine fluoride exceeded three to four times the upper limit of the normal range, while only two times in slightly less number of workers (77%) of the Steelworks (group S). The subjective complaints and bone pains were correlated with excessive urine fluoride concentrations in about 40% of workers studied in groups A and M, and in 18% of workers in group S. These results point to an excessive exposition of people to fluorides from the polluted environment, as well as to a high risk of fluorine retention in bones and osteofluorosis.

    Skeletal fluorosis is a metabolic bone disease caused by accumulation of fluoride and is generally associated with chronic exposure to fluoride-contaminated groundwater, a phenomenon endemic to developing countries. Whereas elevated water fluoride concentrations do not constitute a public health issue in the United States, emergence of skeletal fluorosis as a

    BACKGROUND:  High fluoride ion (F(-)) levels are found in many surface and well waters. Drinking F(-)-contaminated water typically explains endemic skeletal fluorosis (SF). In some regions of Asia, however, poor quality "brick tea" also causes this disorder. The plant source of brick, black, green, orange pekoe, and oolong tea, Camellia

    Objective: To investigate the control effect of water improvement for endemic fluorosis over a long period of time, the health status of the residents in the disease area and the restoration to health of endemic fluorosis patients. Methods: It was investigated that the water improvement lasting for 40 years and the rate

  • Incidence of fluorosis and urinary fluoride concentration are not always positively correlated with drinking water fluoride level.

    The aim of this study was to assess the effect of fluoride on human health, focusing on the incidence of fluorosis, urinary fluoride concentration and fluoride level in drinking water in three fluoride-affected villages of Birbhum district, West Bengal, India. In one village urinary fluoride concentration was very high along

  • Skeletal Fluorosis: The Misdiagnosis Problem

    It is a virtual certainty that there are individuals in the general population unknowingly suffering from some form of skeletal fluorosis as a result of a doctor's failure to consider fluoride as a cause of their symptoms. Proof that this is the case can be found in the following case reports of skeletal fluorosis written by doctors in the U.S. and other western countries. As can be seen, a consistent feature of these reports is that fluorosis patients--even those with crippling skeletal fluorosis--are misdiagnosed for years by multiple teams of doctors who routinely fail to consider fluoride as a possible cause of their disease.

  • "Pre-Skeletal" Fluorosis

    As demonstrated by the studies below, skeletal fluorosis may produce adverse symptoms, including arthritic pains, clinical osteoarthritis, gastrointestinal disturbances, and bone fragility, before the classic bone change of fluorosis (i.e., osteosclerosis in the spine and pelvis) is detectable by x-ray. Relying on x-rays, therefore, to diagnosis skeletal fluorosis will invariably fail to protect those individuals who are suffering from the pre-skeletal phase of the disease. Moreover, some individuals with clinical skeletal fluorosis will not develop an increase in bone density, let alone osteosclerosis, of the spine. Thus, relying on unusual increases in spinal bone density will under-detect the rate of skeletal fluoride poisoning in a population.

  • Fluoride & Osteoarthritis

    While the osteoarthritic effects that occurred from fluoride exposure were once considered to be limited to those with skeletal fluorosis, recent research shows that fluoride can cause osteoarthritis in the absence of traditionally defined fluorosis. Conventional methods used for detecting skeletal fluorosis, therefore, will fail to detect the full range of people suffering from fluoride-induced osteoarthritis.
