摘要： The aim of the study was to develop a model for describing the relationship between the fluoride (F) content in drinking water and foodstuffs, and the urinary F level in residents, of different age groups, residing in low and high F exposure areas in Mitauli block, Lakhimpur (Kheri) district of Uttar Pradesh, India. The rural population at the study sites used groundwater for drinking and irrigation purposes without any quality test. The source of the F contamination in the groundwater was natural as no large industries were located in the study area which contained only a few agro-based industries.The F concentration was measured in the groundwater from 73 sites in Khanta, Khudania, Murai-tajpur, Salahpur, and Usari villages and in the urine of 548 residents. The range of the F concentration in the drinking water in Khanta, Khudania, Murai-tajpur, Salahpur, and Usari villages was 1.0-2.3, 0.5-1.4, 0.9-1.5, 1.8-2.8, and 2.7-4.3 mg L-1, respectively. The urinary F level in the 548 villagers was found to vary in different age groups. The highest urinary F concentration (4.73 mg L-1) was found in younger males, aged 20-40 yr, with the next highest group (3.72 mg L-1) being older females, aged 60-70 yr.
