A group of 20 lactating mothers ageing on the average 28.6 years without amalgam fillings of metall alloy prosthetic appliances in their mouths participated in this study. All individuals were dentally examined, interviewed for possible occupational or food exposure to mercury and samples of blood, urine, colostrum and breast milk were taken for mercury analyses. These were 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 and 0.412 ng Hg/g (non-significant difference). Differences of sera and urine against colostrum and milk were significant (P < 0.05) and represented the ratio of 1 : 1.3 - 2.
Keywords: mercury content; breast milk; serum; urine; lactating mothers; amalgamfree individuals
