Healthy Tips for Menstruation: Metal Toxicity in Tampons

A new study led by a researcher from UC Berkeley has found that toxic metals like lead , arsenic , and cadmium can be present in tampons from several popular brands used by millions each month . The study , conducted by lead author Jenni A. Shearston , a postdoctoral scholar at UC Berkeley , revealed that these metals pose serious health risks . Metals have been linked to various health issues , including dementia , infertility , diabetes , cancer , and damage to vital organs like the liver , kidneys , and brain.

The study found that tampons can be a significant source of exposure to toxic metals , especially since they are used by 50 - 80 % of menstruating individuals for several hours at a time . Despite the widespread use of tampons , very little research has been done to measure the presence of chemicals in these products . The researchers evaluated 16 different metals in 30 tampons from 14 brands and found that all types of tampons tested positive for metals.

Metals like arsenic and lead were detected in varying concentrations across different types of tampons , including organic and non - organic varieties . The researchers highlighted that the presence of metals in tampons could be a result of various factors , such as absorption from water , air , soil , or intentional addition during manufacturing processes . The study also emphasized the importance of manufacturers testing their products for metals to ensure consumer safety.

While the study raised concerns about the potential health risks associated with metal exposure through tampons , experts urged caution and further research to determine the extent of danger to users . The thin tissue of the vagina could provide an easy pathway for metals to enter the body , raising concerns about the impact on women 's health . Future research will focus on measuring the leaching of metals from tampons and the presence of other chemicals in these products.

In addition to toxic metals , recent investigations have also raised concerns about the presence of harmful substances like perfluoroalkyl substances ( PFAS ) in tampons . PFAS , known as ' forever chemicals , ' have been linked to various health issues , including cancer , infertility , and high cholesterol . Manufacturers are being urged to improve labeling on menstrual products and conduct thorough testing for potentially harmful substances to ensure the safety of consumers.
