目的掌握沧县范围内水氟含量状况以及长期饮用高氟水对健康带来的影响。方法普查检测2009年沧县辖区水源含氟量和抽样调查人群氟中毒状况。结果全县517个自然村中,有501处饮用水源氟化物含量超标,覆盖人口占全县总人口的97.5%。重度高氟地区8～12岁人群氟斑牙患病率为80.94%,其中极轻度3.88%,轻度32.4%,中度39.5%,重度5.18%;尿氟检测正常者仅占0.85%,99%的儿童尿氟水平严重超标;16岁以上人群氟骨症患病率为51.49%,其中轻度41.7%,中度7.7%,重度1.82%。结论沧县水氟含量超标严重,地方性氟中毒表现明显,应及时采取有效措施予以防治。
Objective To understand the effect of fluoride content in Cangxian County on long-term high fluoride drinking water. Methods Census test Cangxian area in 2009 fluorine content of water sources and sampling fluorosis survey population. Results Among the 517 natural villages in the county, 501 out of drinking water sources exceeded the fluoride content, covering 97.5% of the total population of the county. The prevalence of dental fluorosis in 8 to 12-year-old population with severe high fluoride was 80.94%, of which 3.88% was very mild, 32.4% mild, 39.5% moderate and 5.18% severe. Only 0.85% In 99% of children, the level of urinary fluoride was seriously exceeded. The prevalence of skeletal fluorosis was 51.49% in patients over 16 years old, with mild 41.7%, moderate 7.7% and severe 1.82%. Conclusion In Cangxian County, the fluoride content in water in Cangxian County exceeded the standard seriously, and the manifestations of endemic fluorosis were obvious.
