Scientists have issued a warning after discovering poisonous heavy metals in dozens of mainstream tampon merchandise. Specifically, lead was detected in all merchandise examined, elevating issues concerning the impacts of this publicity on ladies’s well being.
Tampons are utilized by between 52 to 86 % of menstruators within the U.S., with the typical lady utilizing 1000’s of tampons all through their reproductive years. Not solely that, however tampons spend lengthy intervals of time in touch with the fragile pores and skin of the vagina, which is extra absorptive than different tissues within the physique. Consequently, any contaminants within the tampons have the next probability of getting into our bloodstream.
“Regardless of this massive potential for public well being concern, little or no analysis has been carried out to measure chemical compounds in tampons,” Jenni Shearston, a postdoctoral scholar on the UC Berkeley Faculty of Public Well being and UC Berkeley’s Division of Environmental Science, Coverage and Administration, who led the examine, mentioned in an announcement.
Of their examine, revealed within the journal Atmosphere Worldwide, Shearston and colleagues from Berkeley and Columbia College evaluated the degrees of 16 heavy metals in 30 tampons from 14 completely different manufacturers. They included tampons with completely different absorbencies, in addition to natural vs, non-organic, EU/U.Okay. vs. U.S., and whether or not it included a plastic applicator.
In whole, heavy metals have been discovered throughout all tampon sorts and types, together with detectable ranges of lead.

“There is no such thing as a protected publicity degree to guide,” the researchers wrote. “Any proportion of lead which will leach out of a tampon and attain systemic circulation may contribute to detrimental well being outcomes.”
Lead is a naturally occurring poisonous metallic that may exchange the calcium in our bones and enamel and could be saved in our physique for many years after the preliminary publicity. Over time, this heavy metallic can accumulate and could also be launched again into our blood.
The metallic has been related to a spread of neurological and cardiovascular circumstances, in addition to issues with our kidneys, our blood, our immune system and our reproductive well being.
“Of specific observe, even low-level publicity to guide can lead to neurobehavioral impacts in adults and youngsters, together with decreased cognitive perform corresponding to impaired consideration, reminiscence, and studying potential,” the researchers wrote.
Kids are notably susceptible to guide publicity, as are unborn fetuses, which is likely to be uncovered to guide that’s rereleased from the mom’s bones into her blood throughout being pregnant.
Of all of the tampons included within the examine, the very best ranges of lead have been present in non-organic tampons, these with plastic applicators, and people with increased absorbencies.
“Though poisonous metals are ubiquitous and we’re uncovered to low ranges at any given time, our examine clearly exhibits that metals are additionally current in menstrual merchandise, and that ladies is likely to be at increased threat for publicity utilizing these merchandise,” examine co-author Kathrin Schilling, assistant professor at Columbia College Mailman Faculty of Public Well being, mentioned in an announcement.
Precisely how these metals enter the tampons is unclear, however the researchers have advised it might happen at a number of phases of the manufacturing cycle: metals could also be by chance absorbed by cotton via water, air and soil or they might be deliberately added via pigmentation and whitening.
It’s also unclear how a lot (if any) of the lead and different heavy metals in these tampons is ready to be absorbed into the physique, warranting additional investigation.
“I actually hope that producers are required to check their merchandise for metals, particularly for poisonous metals. It will be thrilling to see the general public name for this, or to ask for higher labeling on tampons and different menstrual merchandise,” Schilling mentioned.
