Scientists warn of toxic substances that you may find everywhere, from fast food packages and frozen foods, through frying pans, to clothes.

How does it infiltrate our bodies?

Packages of frozen foods, fast food, nonstick frying pans, and some clothing contain chemicals known as PFAs, including PFOA and PFOS.

These chemicals consist of a series of fluorine atoms, and the danger is that they do not degrade in the environment;

Which is dangerous to our health, according to a report in Deutsche Welle.

The United Nations Environmental Adviser, Roland Webber, described these substances as one of the most invented chemicals that threaten human health.

And falls under the classification of toxic chemicals - known as "PFAS" - more than 4,500 man-made substances, and they are found all around us;

In soil, drinking water, animal foods, and even inside our bodies.

From the atomic bomb to the kitchen

The invention of chemicals - known as "PFAS" - dates back to around 1938 with the invention of the first chemical of its kind known as Polytetrafluoroethylene PTFE.

Polytetrafluoroethylene was invented because of its ability to protect metals from corrosion at incredibly high temperatures, so it was used in the atomic bomb first, but soon this material appeared in homes all over the world, and was used as a strong coating for frying pans.

Do these substances exist in our bodies?

98% of Americans had BFAs in their blood, while studies in India, Indonesia and the Philippines found BFAs in all of the mothers' milk samples tested.

In Germany, it was found that every child contained permanent chemicals, and in one fifth of the cases the concentrations exceeded critical levels.

This prompted Tim Schauenberg, a reporter for Deutsche Welle, to consider determining the levels of BFAS in his body.

However, it is not easy work;

He has to go to specialized laboratories, which are few in number even in Germany, to perform the necessary tests.

In the end, he found what he wanted in a laboratory in Erlangen (southern Germany).

Schauenberg sent a sample of his blood to a lab, and it was analyzed for PFAS chemicals, particularly PFOA and PFOA, which can damage the liver or kidneys, reduce fertility in men and affect the size of newborns.

Accumulation

Lab results from a blood sample taken from Schauenberg indicated that his body contained 4 nanograms of both acids per liter of his blood.

To round it off, this is about one-thousandth the weight of a grain of sand, which means Schauenberg's body contains PFAS chemicals well below critical levels, in line with the German average.

Thomas Guin - the German researcher who conducted the analyzes - said that the results indicate that these levels of the chemical "PFAS" substances do not pose a threat to Schauenberg's health, according to current scientific research.

Nevertheless, the researcher stressed that it is not that simple, adding that "the main problem is that these substances may eventually accumulate to increase their concentration."

The human body excretes these substances very slowly, and scientists are currently working on finding ways to break them down, but the matter has not been resolved yet.
