目的了解山东省东营市地方性氟中毒流行现状,为制定防控策略提供科学依据。方法采用流行病学抽样方法,调查丁五等6个病村的居民饮用水氟含量,检测8~12岁儿童尿氟含量,调查8~12岁儿童氟斑牙检出率,16岁及以上成人临床与X线氟骨症检出情况。结果6个病村饮用水平均水氟浓度为3.04 mg/L,22份水样水氟浓度均超过国家标准(≤1.0 mg/L),最高者达4.15 mg/L;8~12岁儿童氟斑牙平均检出率59.7%,缺损率11.8%,斑釉指数1.20,最高的码头村氟斑牙检出率达69.4%,缺损率21.5%,斑釉指数1.51;8~12岁儿童尿氟几何均值2.40 mg/L,6个病村均未达到≤1.5 mg/L的控制标准;成人临床氟骨症检出率和X线阳性检出率均为14.8%,病情以码头村最重,并出现2例X线Ⅱ期氟骨症患者。结论东营市地方性氟中毒病情尚未得到控制,需加大改水力度,控制氟源,尽快落实防制措施,以期早日摆脱高氟危害。
Objective To understand the prevalence of endemic fluorosis in Dongying City, Shandong Province, and to provide a scientific basis for making prevention and control strategies. Methods The epidemiological sampling method was used to investigate the fluoride content of drinking water in residents of 6 villages including Ding Wu et al. The detection of urinary fluoride in children aged 8 ~ 12 years and the detection rate of dental fluorosis in children aged 8 ~ 12 years, aged 16 and above Adult clinical and X-ray skeletal disorders detected. Results The average water fluoride concentration in drinking water of 6 villages was 3.04 mg / L, and that of 22 water samples exceeded the national standard (≤1.0 mg / L) and the highest was 4.15 mg / L. The fluoride The average detection rate of teeth was 59.7%, the defect rate was 11.8%, the spot glaze index was 1.20. The highest detection rate of dental fluorosis was 69.4%, the defect rate was 21.5% and the spot glaze index was 1.51. Urinary fluoride The geometric mean of 2.40 mg / L, 6 disease villages did not reach ≤ 1.5 mg / L of the control standard; adult clinical skeletal fluorosis detection rate and positive X-ray detection rate was 14.8% And 2 cases of X-ray skeletal fluorosis patients. Conclusion The endemic fluorosis in Dongying city has not been controlled yet. It is necessary to increase the intensity of water diversion, control the source of fluoride, and implement the control measures as soon as possible so as to get rid of the danger of high fluoride as soon as possible.
