[目的]掌握重庆市燃煤型氟中毒病区人群不同途径摄氟量与尿氟的相关关系,为防治氟中毒提供科学依据。[方法]抽样检测病区和非病区饮水、饮食、空气中的氟水平,调查病区和非病区生活习惯,估算出通过不同途径摄入人体的氟水平,与成人和儿童尿氟水平进行相关性分析。[结果]病区成人和儿童的尿氟含量水平高于非病区,经呼吸道摄入的氟水平,病区远高于非病区,经消化道摄入人体的氟水平病区与非病区无差异。[结论]呼吸道的摄氟量可能是影响重庆市燃煤型氟中毒病区氟中毒病情的主要因素。 [Objective] To master the correlation between fluorosis and urinary fluoride in different ways in population of coal-fired fluorosis area in Chongqing and provide scientific basis for prevention and treatment of fluorosis. [Methods] The fluoride levels in drinking water, diet and air of ward and non-ward area were sampled and tested. The living habits of ward and non-ward area were investigated. The fluorine levels ingested by different ways were estimated. Compared with the levels of urinary fluoride in adults and children Conduct correlation analysis. [Results] The urinary fluoride levels in adults and children in ward were higher than those in non-ward. The fluoride level in respiratory tract was higher in ward than in non-ward, No difference in area. [Conclusion] The fluoride intake in the respiratory tract may be the main factor that affects the fluorosis in Chongqing coal-fired fluorosis area.
