Tampons may have ‘toxic levels’ of lead and arsenic in them, study warns – National | Globalnews.ca
Tampons offered beneath numerous well-liked manufacturers might comprise poisonous metals equivalent to arsenic and lead, in keeping with a latest examine out of the College of Berkeley in California.
The examine, printed within the newest quantity of Environmental International, discovered that every one 30 tampons examined from 14 manufacturers — together with natural tampons — contained lead, with some displaying regarding ranges of different poisonous metals like arsenic.
“We chosen a number of completely different merchandise and examined them for a panel of 16 completely different metals. And we discovered concentrations of each single one of many metals we examined. For a few of the metals, like lead, which is poisonous, we discovered a presence in each single one of many tampons we examined. So we discovered loads of metals,” stated lead writer Jenni Shearston, a postdoctoral scholar on the UC Berkeley College of Public Well being.
However regardless of the big potential for public well being concern, she instructed International Information, little or no analysis has been executed to measure chemical substances in tampons.
Menstruators might use greater than 7,400 tampons over their reproductive years, with every tampon being retained within the vagina for a number of hours, the examine stated. They’re sometimes produced from cotton, rayon, or a mix of each supplies.
A tampon is separated into its parts, together with the (A) non-woven outer overlaying, (B) withdrawal string, (C) interior absorbent core, (D) applicator and (E) wrapper.
Environmental Worldwide
In Canada, tampons are regulated as medical gadgets by Health Canada. The well being regulator’s web site states it “makes certain that the tampons offered in Canada are protected, efficient, and of top of the range primarily based on necessities for licensing, high quality manufacture, and post-market surveillance.”
In an electronic mail to International Information on Tuesday, Well being Canada stated it, “displays data associated to the protection of medical gadgets which might be marketed on the market in Canada, together with menstrual tampons. Well being Canada will assess the findings of the examine and can take motion if warranted. ”
The examine raises issues that these present rules is probably not sufficient.
Tampons are of explicit concern as a possible supply of publicity to chemical substances, together with metals, as a result of the pores and skin of the vagina has a better potential for chemical absorption than pores and skin elsewhere on the physique, in keeping with the examine.
“A whole lot of the metals that they discovered, we naturally have in our physique, our physique naturally makes use of for numerous issues,” defined Dr. Eboni January, a U.S.-based obstetrician-gynecologist.
“Nonetheless, when it’s at poisonous ranges, that’s of most concern to me. Lead was present in just about each tampon and lead just isn’t protected at any stage,” she instructed International Information.
Metals have been discovered to increase the risk of dementia, infertility, diabetes and most cancers. They will harm the liver, kidneys, mind, and cardiovascular, nervous and endocrine programs.
“Arsenic is a recognized carcinogen, interval,” January stated. “It might probably trigger lung most cancers, pores and skin most cancers, bladder most cancers and fertility points.”
She added that she believes the examine was properly executed and hopes extra analysis on the subject will comply with.

‘Discovered metals in all the things that we examined’
The researchers evaluated ranges of 16 metals (arsenic, barium, calcium, cadmium, cobalt, chromium, copper, iron, manganese, mercury, nickel, lead, selenium, strontium, vanadium and zinc) in 30 tampons from 14 manufacturers throughout the US and Europe.
They bought the tampons between September 2022 and March 2023 from shops within the U.S., the UK and Spain and two main on-line retailers.
The researchers didn’t specify which manufacturers they examined, however Shearston stated they chose each name-brand and store-brand merchandise that had been extra well-liked.
Steel concentrations diverse relying on the nation the place bought, whether or not the tampons had been natural or non-organic and whether or not they had been store-brand or name-brand.
However there was one frequent issue it doesn’t matter what sort of tampon or the place it was bought: steel was present in each tampon pattern.
“What’s actually necessary is the consistency of our outcomes, the truth that we discovered metals in all the things that we examined, no matter what its model was or traits of the product,” Shearston stated.
Lead concentrations had been increased in non-organic tampons however arsenic was increased in natural tampons.
A number of poisonous metals had been detectable in all tampon samples, together with arsenic, cadmium, chromium, lead and vanadium. Amongst these, lead had the best focus.
January just isn’t certain why zinc and cadmium had been generally seen collectively, however speculates it could be for hygiene functions.
“Zinc is antimicrobial. Perhaps they had been placing it in there from an antimicrobial standpoint. And people two mixed (zinc and cadmium) truly helped to stop micro organism,” she stated.
How are the metals getting in tampons?
Metals could make their means into tampons in a number of methods, Shearston stated.
“One in every of them is that cotton, for instance, is a reasonably first rate accumulator of metals. So it may take in metals that could be naturally current in soil or water would possibly take in metals from fertilizer. In order that’s a method that some metals may get into a few of these merchandise,” she stated.
“Additionally, if it occurs that the uncooked materials, like cotton, is grown close to a air pollution supply, for instance, close to a highway or close to a lead smelter, a few of the metals from these air pollution sources would possibly float down and land on the cotton.”
She famous that it’s additionally attainable these metals are being added throughout the manufacturing course of, as both an antimicrobial agent, a pigment or a whitener.
Due to this, the authors be aware that they hope producers of tampons are required to check their merchandise for poisonous metals.
International Information reached out to Tampax maker Procter & Gamble and O.B. tampon proprietor Edgewell Private Take care of touch upon the examine, however neither firm responded by the point of publication.
Can or not it’s absorbed into the physique?
The examine discovered lead in all of the tampons examined, however a key query stays unanswered: can these metals be absorbed into the physique?
“We don’t know if the lead can truly come out of the tampon and be absorbed into the physique. So whereas we’re discovering these metals current within the tampon, we will’t say if it’s contributing to any well being impact at this level,” Shearston stated.
She emphasised the necessity for additional analysis as a result of widespread use of tampons.
Whereas the precise results of those metals stay unclear, January identified a regarding issue: the vagina’s absorbency.
“The vagina could be very vascular,” she defined. “So it’s not flat like pores and skin. It has folds primarily. And so what that does is it will increase the floor space, and primarily based on the kind of cell layer that it’s, there’s increased danger for issues to be absorbed within the vagina.”
She used the instance of toxic shock syndrome, which happens when sure toxins from micro organism might be absorbed into the bloodstream by means of the extremely absorptive vaginal partitions, typically related to using tampons.
“With the vagina being as absorptive as it’s, the arsenic in these tampons, that was regarding to me as an ob-gyn,” January stated. “Ladies begin their intervals on the common age of 12. Menopause common age is 51. So these ladies have used a ton of tampons. That is power publicity.”
Time to throw away the tampons?
There’s no must panic and throw out your tampons simply but, however this discovering highlights the significance of ongoing analysis in ladies’s well being merchandise, Shearston stated.
Whereas the examine recognized the presence of metals in tampons, it emphasised the necessity for additional investigation to find out whether or not and to what extent these metals are absorbed by the physique and pose potential well being dangers.
January prompt discussing any issues along with your physician relating to the supplies which may be current in your tampons.
“However we do produce other choices,” she added. “You might have the menstrual cups, you might have the disc, you might have the reusable pads as properly. So do your homework, educate your self, attain out to the producers and ask them to be clear.”
