This paper reports an investigation of contents of soluble fluoride in the environment and foods in Xiushan and Baojing. On the basis of measuring concentrations of soluble fluoride in drinking water, soil, coal, air, fly ash, maize, chilli, and other kinds of vegetables, it is first to expand the pathway of fluoride migrating from coal into human body is through pollution of air by fluoride contained in fly ash on burning of coal, and then via consumption of polluted maize by air. The significant correlation between both the concentrations of fluoride in maize and in fly ash is proved. It is suggested to select the concentration of fluoride in fly ash or in air as the quality index of indoor air and the control target to prevent fluorosis.
本文报道了对秀山和保靖地区环境及食物中可溶性氟含量的调查。在测定饮用水、土壤、煤、空气、粉煤灰、玉米、辣椒及其他各类蔬菜中可溶性氟浓度的基础上，首次揭示了氟从煤迁移至人体的途径，即煤燃烧时粉煤灰中所含氟污染空气，进而通过食用受污染的玉米进入人体。证实了玉米中氟浓度与粉煤灰中氟浓度之间存在显著相关性。建议选择粉煤灰或空气中的氟浓度作为室内空气质量指标及预防氟中毒的控制目标。
