Scientists Discover Lead and Arsenic in Feminine Hygiene Tampons

In total, they analyzed 60 samples representing 30 unique tampons. All 16 studied metals were present in all samples. The highest concentrations were observed for zinc and calcium, and the lowest for arsenic. Among the toxic metals, the highest concentration was of lead - 120 nanograms per gram. Further research will determine whether the metals can leach out of the tampons and penetrate through the epithelium into the systemic bloodstream.
