Since the 1950s, thousands of chemicals called PFAS (per- and polyfluoroalkyl substances) have been used for various reasons, but it is their use in extinguishing fires that has led to widespread pollution worldwide. Human exposure to PFAS is broad and observed in almost every human being, starting with exposure in the womb, because these substances accumulate in the human body over time and do not disintegrate in nature.
This exposure has been linked to many disorders such as hormonal imbalance, weak immune system, reproductive and developmental damages, and poor efficacy of vaccines.
Scientists at the EWG (Environmental Working Group) and Indiana University now tell us that every PFAS analyzed shows almost the same properties of other carcinogens based on the key characteristics of carcinogens, a work structure that was established to evaluate and identify carcinogens, and has performed The researchers looked at 26 PFAS to determine the ability of this chemical to cause DNA damage, induce oxidative stress or cause chronic inflammation, which was confirmed in addition to many other things.
Each PFAS analyzed showed at least one similar trait to other carcinogenic chemicals, despite differences in the report and methods for estimating ratios in the studies reviewed.
The editors of the International Journal of Environmental Research and Public Health wrote: “We have found strong evidence that two PFAS subjects are inducing oxidative stress, which are immunosuppressive, and modulating the effects of mediated receptors. We also found evidence to confirm that some PFAS induce changes in morphogenesis, which have an effect on cell proliferation.
These discoveries were based on previous work that showed us to a large extent the potential dangers of these “eternal chemicals”. A previous analysis of more than 70,000 people living or working in places where drinking water contaminated with PFOA chemicals showed us that they were more threatened by non-Hodgkin’s lymphoma as well as kidney, testis, prostate and ovarian cancer.
DuPont Chemicals used PFOA materials for the Teflon (Tefal) industry. EWG discovered earlier this year that PFAS chemicals are found in drinking water in dozens of cities in the United States, and these materials are widespread in rainwater, which makes their presence in the majority of major US water sources possible.
Alex Temkin, PhD and toxicologist at the EWG and the first editor of the new study, made a statement saying, “Our research demonstrated that PFAS influences biological processes associated with an increased risk of developing cancer. This is of concern, given that all Americans are exposed to a daily mix of PFAS of contaminated water, food and everyday products.
Researchers end their research by noting that officials have a duty to protect their citizens from cancer by preventing human exposure to potential carcinogens, starting with PFAS.
