Does your dental floss contain toxic chemicals?

IANS  |  New York 

Using dental floss could contribute to elevated levels of toxic that can lead to problems, especially in women, including and testicular cancer, high cholesterol, low birth weight, among others, says a study led by US-based

In the study, the team measured the presence of 11 different PFAS (per- and polyfluoroalkyl substances) -- water- and grease-proof substances -- in blood samples of 178 middle-aged women.

The findings, appearing in the Journal of Exposure Science and Environmental Epidemiology (JESEE), showed that women who flossed with tended to have higher levels of a type of PFAS called PFHxS (perfluorohexanesulfonic acid) in their body compared with those who did not.

"This is the first study to show that using dental floss containing PFAS is associated with a higher body burden of these toxic chemicals," said Katie Boronow, a at the institute.

"The good news is, based on our findings, consumers can choose flosses that don't contain PFAS," she added.

Further, the team also tested 18 dental flosses (including three products) for the presence of fluorine -- a marker of PFAS, all of which tested positive for fluorine. The new findings are consistent with previous reports that Glide is manufactured using Teflon-like compounds.

In addition, the study also showed that women who frequently ate in coated cardboard containers, such as French fries or takeout, had elevated blood levels of PFAS

"Overall, this study strengthens the evidence that are an important source of PFAS exposure," Boronow said. "Restricting these from products should be a priority to reduce levels in people's bodies."

Other behaviours that were associated with higher PFAS levels included having stain-resistant carpet or furniture and living in a city served by a PFAS-contaminated
