Abstract
The aim of the research was to compare the dynamites of the deposition and eliminatlon of lead from the teeth In young and adult rats whiich had been poisoned by lead. The rats were poisoned by the addition of lead acetate to their dmiinking water. We determined the lead concentration in the teeth by anodal stripping voltaimetry. In the first part of the experiment, for thiirty days, the rats were given 2,64 nmol/L lead acetate in solution to drink. Within that period the lead concentration in the teeth was six times determinated. Continuing the experiment the rats received tap water to dirtiwk. In this part of he experiment the lead concentration in the teeth was four tiimes measured. The achieved results show that the accumulation and elimination of the lead from the teeth in young rats was faster than those of adult rats.
