FLUORIDE IN HAIR AS AN INDICATOR OF EXPOSURE TO FLUORINE COMPOUNDS

sors was significantly increased in the exposed animals. More fluoride accu- mulated by the inhalatory than by the oral route. Positive correlations were found between the fluoride content in bone and in washed hair (r = 0.696) as well as in unwashed hair (r = 0.647). The results of this study indicate that hair may be a useful indicator of long-term exposure to fluorine compounds.
