Study reveals presence of arsenic, lead, and other toxic metals in tampons | Science & Technology Update
Scientists have discovered toxic metals in tampons, potentially posing a greater risk to women’s health.
A study conducted by researchers from the University of California, Berkeley examined 30 tampons from 14 different brands and found all 16 metals they tested for in each type.
The metals found included arsenic, lead, mercury, nickel, copper, and iron, among others.
The levels of metals varied depending on the origin of the tampons (US, UK, or EU), whether they were organic or not, and whether they were branded or generic.
According to the study, between 52% and 86% of women in the US use tampons during their period.
Contaminated tampons can be particularly dangerous as they come into direct contact with the vagina, allowing for easier absorption of harmful substances.
Absorption of metals has been linked to increased risk of serious health conditions such as dementia, cancer, infertility, diabetes, and harm to the liver, kidneys, brain, cardiovascular system, nervous system, endocrine system, and can also affect unborn babies.

Jenni Shearston, lead author of the study, stated: “Despite the potential public health concern, there has been limited research on chemicals in tampons.
“This study is the first to measure metals in tampons. Alarmingly, we found concentrations of all metals we tested for, including toxic metals like arsenic and lead.”
No ‘safe’ level of metal
Organic tampons had higher levels of arsenic, while non-organic tampons contained more lead, according to the study.
Metals can enter tampons through contaminated water, air, soil, or intentional addition by manufacturers as part of a pigment.
The researchers cautioned that there is no “safe” level of any of the metals tested for.
Ms Shearston added: “I hope that manufacturers will be required to test their products for metals, especially toxic ones.
“It would be beneficial to see the public demand this, or request better labeling on tampons and other menstrual products.”
