This article presents a method of measuring the degree of fluorosis in
people who work in a fluoride-polluted environment by the determinati
on of fluoride in human hair. The oxygen flask method of decomposing a
nd the addition of auxiliary combustible adhesive paper to the filter
paper wrapping the hair sample before ignition, in combination with Gr
an's multiple addition of fluoride electrode coupled minicomputer are
recommended. This method is simple, rapid, and sensitive and hair samp
les are easy to obtain. It is the same for the results of the analysis
of the degrees of fluorosis of workers who work in a fluoride-pollute
d environment. (C) 1995 Academic Press, Inc.
