A study found that tampons contain toxic metals such as arsenic and lead, with concentrations varying based on factors like purchase location and organic vs non-organic. Exposure to these metals through tampons could have health risks, including dementia, infertility, and cancer. Despite the potential health concerns, there is limited research on this topic. Metals may have reached tampons through the manufacturing process or from the cotton absorbing them from the environment. The lead author of the study calls for manufacturers to test their products for toxic metals and for better labeling on menstrual products to inform consumers.
