| 内容記述 | Endemic fluorosis is prevalent in many areas of Hebei Province, China, and represents a considerable health hazard for the local population. An investigation was accordingly conducted from 1980 to 1982 to determine the fluoride concentration in the drinking water, soil, crops, and atmosphere, as well as the fluoride level in human urine and the prevalence of mottled enamel and osteosclerosis, Patients with endemic fluorosis numbered 5,672,539 persons living in 126 cities, 1,200 communes, and 10,727 villages throughout the province. These patients represent 10% of the total resident population. The high incidence areas divide geographically into plateaus, mountains, basins, plains, and coastal regions, Most of the sources of drinking water showing high fluoride levels were shallow wells, although some deep wells, springs, and rivers were similarly contaminated. Fluoride concentrations were generally higher in the northern part of the province and lower in the south. No significant relation obtained between the prevalence of fluorosis and the fluoride levels in grain and vegetable crops or the atmosphere. Although atmospheric fluoride levels were higher in areas of high prevalence of fluorosis, its source was attributed to smoke from coal burned as fuel. The prevalence mottled teeth was found to increase sharply when the fluoride level in the drinking water rose above. 1.0 mg/1, and accounted for 100% of the population when the fluoride level was greater than 4.0 mg/1. In patients from areas of relatively low concentrations, the tooth enamel showed an opaque whiteness. Patients from areas of high concentrations exhibited pitted enamel. Osteosclerosis was also found to increase in severity with higher concentrations of fluoride in the drinking water. As result of this investigation, we conclude that endemic fluorosis in Hebei province is caused by high fluoride in the drinking water. Accordingly, lowering the fluoride concentra-tion in drinking water is the primary measure for preventing this condition. | |||||||
