NEW YORK (Reuters Health) – Dental floss, commonly used to clean teeth of food scraps, can contain toxic chemicals that can contribute to serious health problems, according to a recent US study.
The study was conducted by researchers at the Silent Spring Institute, in collaboration with the California Institute of Public Health and published in the latest issue of the journal "Journal of Exposure Science & Environmental Epidemiology".
The researchers explained that certain types of consumer products, including floss, were contributing to increased levels of toxic chemicals "PFAS" in the body and were badociated with many health problems.
And PFAS, impervious and greasy materials are used in a range of consumer products, including fast food packaging, waterproof clothing and stain resistant carpets.
People may be exposed to substances directly from the products they use and the foods they consume, and may be exposed to air, dust and drinking water. contaminated.
Scientists are worried about the widespread spread of PFAS because these chemicals are badociated with serious health effects, including kidney and testicular cancers, thyroid, high cholesterol, low weight at the birth and reduced fertility, as well as the immune system.
In the new study, researchers measured 11 different PFAS chemicals in blood samples collected from 178 middle-aged women exposed to these substances, including products such as flossing.
The researchers badyzed 18 lines of teeth using a technique called spectral spectroscopy of gamma-ray emissions by particles, three of which contained toxic chemicals.
The researchers found that women who used PFAS products, such as dental floss, increased the proportion of toxic chemicals in their bodies, exposing them to health risks.
"This is the first study showing that the use of dental floss containing toxic chemicals is badociated with an increase in these substances in the body," said Dr. Katie Borono, responsible for the # 39, research team.
"The good news is that based on our results, users can choose a string that does not contain PFAS and avoid coated junk food"
