The concentrations of mercury (total and organic) and selenium in samples of human placentae obtained after normal births from 22 women living in Genova (Italy), were determined by atomic absorption spectrometry. The concentration of total mercury was between < 0.005 and 0.230 .mu.g Hg/g dry weight, and the average value was 0.076 .mu.g Hg/g dry weight. For the same samples, the average percentage of organic mercury as mercury was 65%, with a maximum of 95%. Smaller variations were observed for selenium, i.e. concentration ranging between 0.38 and 1.03 .mu.g Se/g dry weight, with an average value of 0.77 .mu.g Se/g dry weight. The ratio between wet weight and dry weight was determined for each sample and the average value found was 6.32. The placental selenium concentration did not correlate with total and organic mercury content, which is inaccordance with the results of other researchers.
