A groundbreaking study conducted by researchers at the University of California, Berkeley has shed light on a concerning discovery – small traces of arsenic, lead, and other toxic metals have been found in multiple brands of tampons.
Published last week in the scientific journal Environment International, the study examined 30 tampons from 14 different brands sold in the U.S., U.K., and Greece. Researchers tested for 16 types of metals and found that all types of tampons contained limited amounts of lead. Lead, a toxic metal with no safe exposure level, was present in all sampled tampons.
Lead concentrations were higher in non-organic tampons, while arsenic was higher in organic tampons. The lead found in the average tampon was equivalent to about 25% of the lead present in a typical U.S. cigarette.
Lead is known to cause neurological damage, and the researchers expressed concerns about the potential dangers of metal exposure through tampon use. While it is unclear whether the metals can leach into a person’s bloodstream and impact health, the researchers emphasized the need for further research to assess the risks.
Manufacturers have been called upon to test for metals in tampons, as the metal traces could come from the soil in which the cotton is grown or contamination during the manufacturing process. Health Canada is currently assessing the findings, and if warranted, will take action to address the issue.
The study’s lead author, Jenni A. Shearston, expressed surprise at the findings, highlighting the importance of understanding the potential health risks associated with using these menstruation products. As the investigation continues, more studies are needed to determine the extent of metal absorption and its impact on the health of individuals using tampons.
