Narażenie mieszkańców Poznania na fluorki. Cz. II. Fluorki w moczu oraz włosach dzieci szkolnych
[The exposure of fluoride to the Poznań’s inhibitants. Part II. Fluorides in childrens urine and hair]

ABSTRACT

In view of the plans of fresh water fluoridation in Poznań the necessity arose of obtaining of information about the exposure to fluoride compounds. The reported study was carried out in Poznań and environs. Urine and hair samples of children were obtained. The determinations were done with a ion- selective electrode. The mean fluoride concentrations in urine were between 0.3 and 0.9 mg F/dm³. The concentration in hair was 2.2 mg F/g in Poznań and 3.3 mg F/g in Luboń. These values were, however, not exceding the acceptable ones. In Luboń the concentrations of fluorides in hair was 50% higher than in Poznań. The authors believe that the possible cause was Fertilizer Chemical Works in that location.
