A concerning level of metals has been found in tampons raising questions about potential health risks associated with their use
The study analysed 30 tampons from 14 different brands and discovered measurable concentrations of 16 different metal(loid)s, including some toxic metals like lead, cadmium, and arsenic.
Tampons, widely used by between 52–86% of menstruating individuals in the United States, are designed to absorb menstrual blood using materials such as cotton or rayon/viscose. However, these materials can inadvertently contain metals from agricultural or manufacturing processes.
Why is this concerning?
The concern lies in whether these metals, absorbed by the highly absorptive vaginal tissue, could lead to systemic exposure and potential health implications.
Lead, a well-known toxic metal with no safe exposure level, was found in measurable quantities in the tampons studied. The study reported a geometric mean concentration of 120 ng/g of lead, alongside elevated concentrations of cadmium (GM = 6.74 ng/g) and arsenic (GM = 2.56 ng/g). These findings highlight a previously unrecognised potential source of metal exposure for menstruating individuals.
The research also examined how different factors might influence metal concentrations in tampons. Variations were observed based on the region of tampon purchase (US versus European Union/United Kingdom), organic versus non-organic materials, and store-brand versus name-brand products.While non-organic tampons showed higher lead concentrations, organic tampons exhibited higher levels of arsenic.
Are organic tampons a better option?
Investigations need to go underway to understand whether these metals can leach out of tampons and enter systemic circulation through the vaginal epithelium.
This step is essential in understanding the potential health risks presented by prolonged exposure to these metals.
The findings show the importance of consumer awareness and regulatory scrutiny regarding the materials used in feminine hygiene products.
Manufacturers may need to reevaluate their production processes to minimise the presence of harmful metals in tampons. Furthermore, consumers are encouraged to consider the choices available to them, including organic options which, while not free from metals, may offer a different metal exposure profile compared to conventional tampons.
As this research gains traction, health experts and regulatory bodies are expected to delve deeper into the implications for public health and safety. Ensuring the safety of products used intimately by millions of individuals is paramount, requiring collaborative efforts between researchers, manufacturers, and regulatory agencies.
While tampons provide a convenient solution for menstrual hygiene management, the presence of metals raises valid concerns about potential health impacts. Continued research will be crucial in providing clearer guidance on safe usage and regulatory standards aimed at protecting consumer health.
