[Urinary fluoride excretion as proof of exposure in welding with lime electrodes].
In a model experiment 8 test persons each were given 1 mg and 2 mg fluoride per os. In a subsequent period of urine collection of 4 hours on an average 10% of the adduced fluoride were eliminated. Taking into consideration extraprofessional intake of fluoride may be concluded that the estimation of fluoride in the urine of welders working with Kb-electrodes may give references to the individual load of the respiratory tract by weld fumes.
