摘　　要：用水浸、酸浸超声、灰化及高温燃烧水解法分别测定煤烟型氟中毒地区环境样品中不同形态氟化物。测定结果表明,土壤中水溶性氟约占1％;室内空气中气态氟约占总无机氟的54～83％;粮食总氟含量中的70％以上为酸溶性氟化物。The forms of fluoride in environmental samples from an endemic fluorcsis area with coal-smoke pollution were determined by different methods. The results indicate that the water-soluble fluoride content in soil samples are nearly 1％, the concentration of gaseous fluoride in indoor air samples are 34-76％, and more than 70％ of the total fluoride content in food samples are acid-soluble.
