目的了解新疆阿克苏市饮水型地方性氟中毒防治措施落实情况,动态观测病情变化趋势,综合评价改水工程运行效果,为及时调整防治措施提供科学依据。方法采用随机抽样方法,调查抽取的改水工程的运行情况及相关指标,监测病情的变化。结果抽查改水工程10个,合格率70%,8~12岁儿童氟斑牙检出率为70.8%,氟斑牙指数1.50。临床氟骨症检出率15.4%。结论阿克苏市改水后,生活饮用水水质生化指标已达标,理化指标70%达标,因此改换水源是预防饮水型氟中毒最有效的方法。
Objective To understand the implementation status of drinking water endemic fluorosis in Aksu, Xinjiang, to dynamically observe the changing trend of the disease, comprehensively evaluate the operation effect of the water diversion project and provide a scientific basis for timely adjustment and prevention measures. Methods A random sampling method was used to investigate the operation status and related indicators of the water diversion project and monitor the changes of the disease. Results A total of 10 water improvement projects were selected, with a pass rate of 70%. The detection rate of dental fluorosis in children aged 8 to 12 was 70.8%, and the dental fluorosis index was 1.50. Clinical skeletal fluorosis detection rate of 15.4%. Conclusion After the water is changed in Aksu City, the biochemical indicators of drinking water quality have reached the standard 70% of the physical and chemical indicators, so changing the water source is the most effective way to prevent drinking water fluorosis.
