Overview

A group of 20 lactating mothers ageing on the average 28.6 years without amalgam fillingsof metall alloy prosthetic appliances in their mouths participated in this study. All individualswere dentally examined, interviewed for possible occupational or food exposure to mercury andsamples of blood, urine, colostrum and breast milk were taken for mercury analyses. Thesewere performed by cold vapor atomic absorption spectrophotometry with the detection limit0.10 ng Hg/g. Mercury levels in sera and urine amounted to 0.188 and 0.213 ng Hg/g(non-significant difference). Colostral and breast milk levels of mercury amounted to 0.321 and0.412 ng Hg/g (non-significant difference). Differences of sera and urine against colostrum andmilk were significant (P < 0.05) and represented the ratio of 1 : 1.3 – 2.

Key words:
mercury content – breast milk – serum – urine – lactating mothers – amalgamfree individuals
